In short

TEM’s “AI-native infrastructure” for electricity transactions—price discovery and moving money more efficiently to cut intermediary/labor costs—plus lessons on founding, scaling, fundraising, hiring, and culture.

Key claims

founders aren’t usually happy after selling; the journey and “company market fit” matter; build the “new nucleus” (transaction layer) rather than peripheral tools; raise money only when needed (valuation matters less than exit); hire for outcome ownership and high quality bar; culture can’t be rebuilt once eroded; use an “intelligence layer” (docs/recordings/data) to enable flatter, outcome-based orgs.

Notable examples

Joe’s friend’s catering business shut down after ~400% energy price spike; a trader got ~£750k bonus; TEM’s early liquidity problem led them to build their own utility in ~8 weeks and launch “Red”; customers include schools saving ~$75k/year and data centers saving ~$2m/year; Series B closed ~$75m in two weeks after months of prep.

Guests

Joe McDonald, TEM co-founder/CEO (15 years in energy; prior company sold to Shell in 2019); Adam Chirkowski, partner at Albion VC (13 years; invested ~$150m into renewable generating assets; energy-focused investor).

0:00Joe McDonald:I don't care what you index on, what you think your outcome is going to be, and I've lived this. I don't think any founder is that happy when they sell their company. I have not yet met someone who is. So I've learned that the journey is important for me. So it self-selects also the kind of people you can bring in and the people that stay and the kind of leaders then you can develop at an organizational level.

0:24Adam Chirkowski:A big warm welcome to another 40 Minute Mental Live. I am very excited to have Joe and Adam here today to hear all about TEM's incredible scaling story. There are lots of things I'd love to discuss, but we really should start with proper introductions. So if you don't mind, maybe we'll start with you, Joe. Can you just introduce yourself and tell us a bit about TEM?

0:45Joe McDonald:Yeah, so I'm Joe, one of the co-founders and CEO at TEM. A little bit about my role, really, I'm kind of unchanged since the beginning, right? I'm there to look after the product strategy, to make sure we're making the right bets, to ensure that kind of meta problem solving of all the smart people I have who can't solve those problems kind of arrive at my doorstep and then evangelize that mission, storytell, and make sure we have enough money in the bank to build a generational company. So just a few things really. Yeah, it sounds like a small job. Actually a little bit about what I did before as well.

1:15Joe McDonald:I've actually been in the energy space for about 15 years. I joined a company as a very naive 21-year-old, thinking I was joining a startup with smoothies. I was actually founding a company with two other guys in the energy space. We sold that to Shell in 2019. So scaled the company, sub-hundred million dollar exit, but amazing set of learnings. Before that, I was getting rejected from Google. Before that, I was doing some odd sales jobs. And before that, I was actually rejecting the law because I actually qualified as a lawyer back in the day. A little bit about Tem. So Tem is a Series B company.

1:43Joe McDonald:We are building the kind of AI native infrastructure for electricity transactions. What that actually means is that we do price discovery and we move money way more efficiently between the users of a system, right? People who need to pay for the energy they use and the people that need to get paid for the energy they generate. And we use quite a complex machine learning and reinforcement learning infrastructure combined with a gentic kind of operating system that just strips out the entire intermediary and labor cost of running an energy company. and ultimately puts more money back into the pockets of our users, right?

2:15Joe McDonald:So a school was saving$75 ,000 a year and they can have another teacher again and a rugby club might solve their problem of 14 ,000 extra costs that they shouldn't be paying, all the way through to data centers we work with that are saving over like$2 million a year through our transaction infrastructure on their energy costs. Incredible.

2:32Adam Chirkowski:And I always have huge respect for anyone that's been a founder before and then wants to go again. So we'll probably get into that. It's enough to traumatize a lot of us, but we're all broken somehow that's the way i think of it indeed well thank you i can't wait to dig into the story in more detail but adam my name's adam i'm a partner at albion vc we have been around for 30 odd years which in uk vc terms is one of the longest standing especially in london we invest fundamentally in founders that are looking to change the world everything from from pre-seed through to series A and generalist.

3:07Adam Chirkowski:We've got clusters in fintech and cyber and big data and AI. And from my sins, I've done quite a bit in the energy space. And that's because I've been at Albion 4 getting on for 13 years now. And back then, we actually didn't just do tech. We didn't just do B2B tech. We did some infrastructure investing as well. And I helped raise and deploy about 150 million into renewable energy generating assets back when they were fit subsidized by the government. So knew enough about renewable energy and the energy system to have some idea what Joe was talking about. Interesting. Thank you very much. We're going to get into this story, but we should probably start with how you actually met.

3:51Adam Chirkowski:So I don't mind who goes first on this. Tell us a bit about how you came together. I'll go for that because I can remember it. It was actually on an online demo day, which there can be variable quality online demo days. And every now and again, you get a diamond in the rough. But yeah, I saw Joe pitching on that kind of 10 minutes. It was, I mean, it's happenstance, right? Because it's a renewable energy background that I kind of understood. I had a semblance of understanding of what the kind of problem, high level, what the problem was that Joe was trying to solve, Joe and the team. as in when we had generating assets we were always thinking about ways to try and sell the power more locally kind of direct to the local customer and cut out a whole load of the margins which happen when you go centrally without trying to do it with private wires that was kind of from an infrastructure aspect what joe was talking about was much more from the tech point of view but yeah it was an online demo day and even with that mustache i followed up and kind of went from there I love that.

4:54Adam Chirkowski:And it is one of the best moustaches we've ever had on the podcast. So that's something. We should talk about the origin story of Tem, Joe. So taking back to the very beginning, you're doing online demo days, looking for investment. But where did the original thesis for Tem come from? And tell us a bit more, alluded to it a bit, but a bit more about the mission that you were really setting out upon.

5:14Joe McDonald:It's funny, right? I think you see this a lot in people talking about their journey. I think when you look at historically, it's quite a linear path. It makes sense. At the time, it's all felt like absolute chaos. But I can explain it from that linear standpoint, which is it was built over 10 years, right? Because my first company was solving a peripheral problem in the energy market. It was building like automation and trading services for renewable generators and aggregating battery storage and what we call now virtual power plants. When I joined that, I honestly had no idea when you flick a light switch on how it all worked, right?

5:45Joe McDonald:So I just love the idea that electricity is more like data than it is like a fossil fuel commodity. So there was surely more opportunity if the whole market is shifting to electricity to utilize technology to completely change the way things are done. But I sold that to Shell and I saw probably for the first time, and I was a handful of people in the world that actually seen the end-to-end electricity transaction at that point. And it was that realization and understanding all the systems, all the people, all the reasons, all the behaviors, it kind of came together to like, unless we change the nucleus here, we're never going to actually build true innovation into this market.

6:20Joe McDonald:We're all going to be innovating around peripherals, but it all comes back to actually the transaction of the electricity itself. But I think the moment it flipped, and it really was a moment, it was in one week, it was in 2022 during the energy crisis. I'd been mulling over this, walking the dog thinking like, maybe I'd do like the end of life pension from Shell, and maybe I can just do a nine to five. And I'm sure my partner will be really happy with that. But I met a friend on a Tuesday and she came to me in tears. She was shutting down her catering business after six years because her energy price had just spiked by about 400 % for an external contract.

6:51Joe McDonald:And she just came to me, she was like, I don't understand why. And she was looking for advice. Thursday, I went for dinner with my friend down in London Bridge, who's an energy trader. He'd just been paid about£750 ,000 bonus for the quarter. And it was just this disparity of realizing in the same way, I think maybe people thought about the cost of compute back in the 1970s. Like if we can bring down the cost of the electron in the same way, it really empowers an entire new phase in kind of human history because it's real people that are affected by this cost. Like that was my friend who was affected by that.

7:22Joe McDonald:I just thought there has to be a different way to do this. So with a little bit of the, okay, let's do this again and make sure I take all the learnings. I think I learned what not to do, not necessarily what to do with the next business. And to kind of prove myself, like we talk about growth mindset all the time at Tem, if I wasn't willing to go again, take all those learnings and take a risk. Who am I and what have I stood for for the last few years? It kind of all came together with the three other founders who I'd worked with as well. And I took the idea to them. I expected them to say, you're crazy.

7:49Joe McDonald:This is impossible. They all quit their jobs that week. Right. So that was that initial kind of new. And since then it has been a whirlwind of mistakes as well. But that inception moment, yeah, is incredibly clear. And we still come back to that every single time we think about the decisions we're making at 10. I love that. And And that is the perfect segue, talking about mistakes.

8:06Adam Chirkowski:We would love to talk about the early days in the business. I'm sure there were many challenges, probably things you underestimated. Even though you're a second-time founder, this is such a big problem space. There's always challenges when you're trying to grow a business. So can you talk to some of those early challenges that you have faced and how you overcame them?

8:23Joe McDonald:So I think there is incredible power in the naivety of a first-time founder. Because I think if you truly knew, you probably wouldn't do it. And equally, when I was doing it the second time around, I think I was overanalyzing things. Oh, how did I do it last time? Can I do it differently? So I think there is a real power in that naivety. However, an example of that naivety failing me again with the second one was, in my head, I realized if you build the new nucleus of a system, the new infrastructure, and you can win on price, and no one else can compete because this is a technology play, it's a network effect play, you can't just simply reverse engineer this.

8:56Joe McDonald:Every other participant in the energy market will eventually die. So my view is I'll bring it to them and say, look what I've created, this infrastructure, you can use this. And obviously if you don't use this and someone else does, you're going to lose. What I didn't expect is all 20 utilities in the UK to be like, no, why would we use this infrastructure? Why would we cannibalize our own profit streams? Who are you? What kind of proof points do you have? So in my head, I was so excited from that pitch deck. I was like, everyone will get this. And I didn't realize that actually what it ended up meaning is, and this was quite close to the funding realm, we were like, we couldn't get started.

9:29Joe McDonald:We couldn't get liquidity into the infrastructure. So it ended up meaning that we built our own utility. We had to basically build a utility in about eight weeks to get our first few customers in. And then actually Red, which is the product you'll see in the market from us, that is the kind of first UK Neo utility that is built on top of our infrastructure. And that has become our stalking horse in the market. And long story short, three years later, everyone's coming back to us saying, oh, okay, that thing you sold us,

9:55Adam Chirkowski:can we have it now please yeah i love that but that must be very validating and it shows how far you've come it's real i think it's one of the things we really try to focus on the podcast is just regardless of the success of the founder and the story where they are today it's always good to reflect there are those moments of the oh god and that's a perfect one for any founder that's going to listen and watch this adam you clearly saw immense potential in joe genius very early on yes the genius the mustache but they're clearly the team the idea the concept you were hooked so what made it such a great opportunity when you saw that i think there's a there's an element of many stars aligning many tailwinds that go with it i mean the energy market is if you're looking to build big global businesses or you're looking to invest the energy market is a market of true global scale that rivals pretty much every other market so market size is there you always have to ask yourself with that kind of market the why now question because it's been pretty stuck in its ways for what 50 60 years it's like why now why is this market kind of on the cusp of shifting and you had the energy transition going on and a complete 180 shift of the supply model.

11:20Adam Chirkowski:You had a whole load of tech advancements pretty much in the two or three years before you, which kind of enabled what was going to happen. And then you started having the energy crisis where prices were just going through and all of a sudden this stable line in the P &L was killing businesses left, right and centre. So people were actually much more willing to say, right, we're not just going to go with the status quo. We need to find something else. Otherwise, it's kind of what we die. So there's all those kind of tailwinds that makes it exciting. But fundamentally at that early stage, it's down to the team.

11:54Adam Chirkowski:It always is. It's the vast majority of the decision is down to the team. And it's not just Joe, but there's Jay Spartak and Ross as well. And four founders can be problematic. It's actually probably more often problematic than not. But each one of them brought a very specific skillset to the table, which turns out being handpicked for that reason. But they'd also worked together for kind of a decade. And also in energy, I think energy is a very complicated space, which brings real kind of defensibility, potential to build defensibility moats, which in today's age, everyone is craving. But you really need to know what you're doing.

12:37Adam Chirkowski:As Joe said, it's one of the few that's sort of the end-to-end transaction. And you think that can't be true. you know massive global market the venn diagram of skills in terms of the knowledge that in-depth knowledge but also the tech skills and the startup experience and that kind of mindset just does not grow in trees on trees in energy you're getting it more and more but it's a rare combo and then there's the ambition that you just gotta love i mean he said to me we're going to take down big energy and we're in some terrible building by london bridge with little space eaters

13:13Joe McDonald:The first board, it was too cold. So everyone was sitting on these old sofas with coats on and space seats. And he's sitting there going, yeah, we're going to take down big energy.

13:20Adam Chirkowski:Can't even afford our own heating. I love that. And the irony got lost to me that you exited your previous business to Shell. I mean, ambition is one thing and having that vision. It can sound glib to say anyone can say that. There's also a real strategic idea of how to get there. And not just sat there, you know, in an armchair in a cold building saying, yeah we're going to take it's like this is how we're going to take down the energy step by step and a thesis on how the world is developing which means that those steps make sense right and that clarity must have given you a lot of confidence and conviction well i was pretty cold but other than that yeah and you've seen these amazing milestones i'd love to hear what you're as an investor what your kind of favorite the bits to stand out to you on the journey so far and particularly how joe and the team have evolved as leaders in that time frame i think when the The platform and Rossa and the whole thing really started to rip.

14:15Adam Chirkowski:The first year, and I think it probably took you guys longer to build than you thought post-funding round, by a good six to eight months. But it was always very purposeful, that build, because it was never, we need to go from zero to one. This needs to be built in a way that can 100 ,000x. So there's no point rushing this and getting it wrong. And then a period of kind of flushing, opening the taps a little, bit just to test and see where water leaks out of the pipes and do that but then turning it on in earnest which was probably i think about 18 months ago and just seeing it rip from there is very satisfying and then i mean the series b that you guys have just done it kind of validates everything because light speed came in and energy there still isn't a space even with all these there's a lot of size and a lot of factors which make you would think make it very attractive it ticks a lot of boxes but it's still not a space that's been properly leaned into by the big kind of global vcs so having one of those the more generous alongside some great kind of energy specialists as kind of validates everything that's awesome and congrats on the series b exciting milestone a lot of the people in this room will have done fundraising before and know how painful it can be.

15:36Adam Chirkowski:A lot of people listening will be either going through that process as founders or have been through it before. So I'd love to hear about your own experience of the fundraising journey and any learnings you can share with our listeners.

15:47Joe McDonald:Yeah, for sure. I mean, my first kind of reflection is try not to compare yourself against anyone else. I always get sucked into that. Oh, they're raising this quickly and this amount. And actually just really focused for me on what do we need to do to achieve our mission, right? We knew we were going to build a generational company, we knew that wouldn't be for everyone. So we had to go in knowing that eight out of 10 people will self-select themselves out even in the investment process. And that's been pretty much the case every time. So we've been very targeted on who we build relationships with well ahead of the funding round.

16:17Joe McDonald:So we have that planned. We then have the materials before we share anything to market. We really go quite deep, which means that we raise money when we don't need it. Because the moment we start raising money in the windows where we need it, everything gets compressed, you rush. And actually, the longer you're out in the market, the worse. It's just a simple fact, right? So for example, our Series B, we closed a$75 million round in two weeks. But we had spent four or five weeks blitzing preparation beforehand. And I'd been speaking to Paul from Lightspeed for nine months before that. Part of the, I think, philosophy that enables this is this idea that we had as founders, which, especially if you're trying to build an insanely ambitious company, don't be greedy.

16:57Joe McDonald:So raising money when you don't need it might mean that you're giving up a little bit on the valuation. Valuation means nothing until exit. I've learned that very firsthand. So it's just a necessary means to protect investors, make sure they're obviously not getting diluted. And my team, obviously, they're not getting diluted too much. But it's just a stepping stone to get there. So finding the right partner, doing all the prep, and then coming out incredibly efficiently in a very clearly timed process has worked well for us and hopefully will continue to work well for us from this point onwards.

17:24Joe McDonald:It's easy though now to see it with the traction, right? When you look at Adam, he was making a bet where everyone else said no, rightfully so, because I couldn't explain it very well. And I was getting way too geeky about it. Whereas now we can be like, okay, zero to nearly a billion dollars in gross revenue for the transaction platform in 24 months. Like that growth story, sixth or seventh fastest growing company in Europe. These things then just help tick the boxes, but it will still come down to the nuance and the explanation of risk and defensibility and why Claude won't just take you out the market.

17:51Joe McDonald:All of these things do matter and being prepared really, really helps. Yeah, definitely.

17:55Adam Chirkowski:Adam, when you look at particularly impact-driven founders like Joe, what do you look for to distinguish between kind of true conviction for the space and just like a good pitch, narrative, great presenter? And how do you sort of test for that to sort of work out who's worth the risk? I think a lot of it, A, comes down to really knowing the value proposition or really knowing the pain point. and not just kind of having scanned the horizon and gone oh that looks interesting i think people that have really almost lived the pain that they're trying to solve lived the problem like i said these guys had been in energy for you know 10 to 15 years so they it was day in day out kind of really understanding it also that also helped because i know i know joe's not going to sell for 100 million because the problem won't have been solved so it would keep him up at night right he'd have nicer sheets but he'd be lying there going i haven't solved the problem like the underlying motivation which i think you've said before in your case is that injustice that you're talking about you know the friend going out of business versus that kind of injustice hadn't been solved so it's really understanding the motivation i think for impact driven especially I've done a fair amount in the climate space, energy space.

19:15Adam Chirkowski:I think it's very important to me, I always look at things that are at the intersection of economic and say environmental impact, right? If you're not having the economic impact, as much as you would like to think that it shouldn't matter, that's not how the world works. You need to have an economic impact to scale, to get to a scale that any other kind of impact actually moves the needle. So, I mean, these guys, yes, behind it, there's a lot of renewable energy, etc. But they're selling on the basis of cheaper power, right? 30 % cheaper power, up to 30 % cheaper power. That's why you scale quickly, right?

19:55Adam Chirkowski:Because at the end of the day, the P &L impact, it's why people go out of business. Totally. Yeah. Thanks for sharing. And that combination of purpose and profit is clearly compelling from an investor standpoint. but also from a talent perspective, we see it every day. When we talk to execs who are often very good, very cappy in their roles, the things they will consider are purpose-driven businesses where they can get behind the mission. And this is one I'd imagine everyone coming through the door, the applications you'll get, hopefully a few more after this podcast will validate that. I know you are very passionate about building a really strong people function.

20:29Adam Chirkowski:It's really important to you, which we here at Amplify Group are really super excited to hear that. Can you share a bit about why it's so important to you and what that actually looks like in a TEM context?

20:40Joe McDonald:Yeah, I think it really boils down for me for two reasons. One, actually just sharing an experience is with our first company, we had a great culture. We were an in-office small team. We didn't invest in our culture and our structure and we didn't sort of innovate on what we needed to be as a company. and then by the time we got to about 130, 140 people, just the wheels started falling off. And what we learned was you can't put those back on. Once your culture started getting eroded and you moved to like 60 % developer churn because there's friction in the company and we're still all in the same office.

21:14Joe McDonald:So I realized that for me, if I can build a remote first company that allows me to get diversity of talent at an extreme level, which is gonna be necessary for us to solve the problem, it doesn't actually matter if I'm in person or not. It matters about having the right people and the right structures to support them. So I knew I had to be very, very intentional about culture and what I call like company market fit. So almost the moment after we found product market fit, I have spent, I'd say 70 % of my time on company market fit. That is thinking about culture, organizational structure. We call it our heartbeat, like our execution process, our empowerment, our progression.

21:47Joe McDonald:I got that very wrong. I've tried different things. Sometimes I've tried to reinvent the wheel. My general advice would be don't try that. But right now there is a new world emerging of how to build a new company. And that's probably only become possible in the last four months. So I've become very obsessive about ensuring I have other people in the company. And I would say the people team itself is also changing. It's not necessarily just your traditional people team and HR and processes now. It's about finding people who can understand how to embed and embody and protect the culture, think about the operational efficiency, build your intelligence layers, like work on standardized processes for how you hire great talent, how you bring people into a tribe.

22:24Joe McDonald:That takes a lot of effort. My first hire was a head of people. above everyone else. So I think that's paid out really well for us. The second point, I said this, we were at Temfest recently. We do twice a year. We fly everyone out for a very intense three, four days together to spend in person because you can't replicate that remotely. If you don't enjoy the journey, it's not worth it. I don't care what you index on, what you think your outcome's going to be. And I've lived this. I don't think any founder's that happy when they sell the company. I have not yet met someone who is. So I've learned that the journey is important.

22:54Joe McDonald:For me, the journey is about who you share it with and so you have to have the right people those people have to annoy you they have to inspire you you want to get out and like fight for them every day and that is the culture of a company defining that equally to say what you're not is important because a culture that's not suitable for everyone is a unique culture and that's a good thing so it self-selects also the kind of people you can bring in and the people that stay and the kind of leaders then you can develop at an organizational level.

23:21Adam Chirkowski:Yeah, I love that. So if you're designing your org from scratch today in this new world that's emerging, what would you build differently? And what does the company stack look like in 2026?

23:33Joe McDonald:I will regurgitate things I've learned from the market, right? This is not, and I think the learning for me as a founder is sitting in a room by yourself and thinking you're a genius is not a good idea because we're not and ideas are quite cheap. So I've been extracting things. I think Jack from Block had done some great thinking on this and you've seen Tom from Monzo has gone on to YC, think about company structures, and there's a lot out there at the moment. The way we see it, if I was building from scratch, which is now what we have done today, there does not need to be more than three degrees of separation between the founding team, or we call it our Elrond, because we're Lord of the Ring geeks, that you're bored, and then your ICs.

24:07Joe McDonald:Because we have traditionally for hundreds of years built things around information flow structures, and that's why you needed management, like to take information and decentralize it to your teams. And so you had to create hierarchies. And I think now with the AI tools and LLMs, what you're able to do is remove the need for that hierarchical information flow. And you can create an intelligence layer at your company. So what I would do is I'd obsess about where is all your documentation? Where is all of your recordings? Where is all of this intelligence layer that's built around databases that are secure, that have good access rights, that allows anyone in the company to prompt for an answer rather than wait to hear that flow up and down?

24:44Joe McDonald:It creates a much flatter company, but also creates a company that can still move at amazing pace because with access to that information, you can create lots and lots of owners who can just autonomously work and execute and move very fast. And I think it also then really challenges the model of managers, right? Where at our space, the entire structure of the company is set on outcome ownership, not team size. So I think if you combine that kind of structure, you're going to get amazingly smart people who can move incredibly fast, either with agents or with teams. and we can stay very close to the problem.

25:16Joe McDonald:And you can bring everyone closer to that problem, which I think really helps in terms of both motivation, understanding and speed of execution. That was impossible five months ago, and it's still not perfect today. And people go, oh, I'm being managed by AI. No, no, what's happening is this intelligence layer is giving you the power to performance manage yourself and understand your gaps, not wait for your one-to-one three weeks down the line with your manager who may or may not have done all of the work up front to look at how to improve you as an individual. Yeah, it's an absolute game changer.

25:42Adam Chirkowski:It was a very exciting time to be in this space and great how intentional you're being and how passionate you are about. That's something I would encourage all founders listening to this to lean into it. It will make a big difference for your business.

25:52Joe McDonald:I came to the board, didn't I? I was like, am I insane? Like, shouldn't I be spending more time on the product? But it really starts to shift to execution. And execution, I think, is defined by your culture. And actually reading stuff like Dario from Anthropic has spent 70 % of his time on culture over the last 12 months in the fastest growing company in human history. I think I can take a lot of like okay maybe I am doing the right thing here I'm not insane

26:14Adam Chirkowski:no I love that we know firsthand as headhunters how hard hiring is I'd love to ask you Adam first then we'll come on to Thames experience of this like what would you say are the most common mistakes you're seeing founders make across your portfolio across your network when it comes to hiring not across our portfolio because all our founders are perfect they don't make mistakes but I mean, the top one just forever has been trying to hire too fast, right? And it's not necessarily just trying to hire too fast that's the problem. It's the quality bar. And it's making sure that you maintain a really, really high quality bar.

26:51Adam Chirkowski:I mean, that's something Joe is a good at, but also can struggle with, as in the bar is so high. Too high. yeah well i'm not too high but it then becomes very difficult to hire a lot of people very quickly because you can't do both you can't hire loads of people quickly and stick to the same quality bar i would always gun for keeping the quality over trying to get too many people through the door because if you get a load of people through the door that aren't then they have to churn then you have to rehire them and it just ends up taking longer and being more of a drag on you then yeah definitely a mediocrity spreads and when you get exceptional talent they are talent magnets right so it's a real signal to the market when you you know when that bar is super high and it's amazing for candidates to get through that sort of process and they're surrounded by incredible people so when you do find amazing people get them on board and i wouldn't be too sensitive to to price if they're that good right there is an old adage that if you pay peanuts you get monkeys music to a headhunter to see us there.

27:51Adam Chirkowski:Thank you very much. Appreciate that. Joe, what type of talent are you looking to attract? And can you tell us, our audience, any little tips, tricks, things that are helping you attract these world-class operators?

28:01Joe McDonald:Yeah. So we optimize every single person at TEM for outcome ownership. I don't look at inputs or outputs. I tend to not look at logos either of what they've done. I look at what have they owned and what level of ownership and how can they autonomously execute on achieving the outcomes that they want to have. So it requires people who are comfortable in ambiguity. It requires people who really love to own a problem. And in itself, we can now shift away from that needing to be the traditional, as I said, managers and leaders of teams that you can have individuals that have literally no management, but have huge outcome ownership, have a swarm of agents and still need to sit at the table and make big strategic decisions with the business, which I really enjoy to kind of have that different in the kind of specialism that now can be brought up to the highest points of the company.

28:45Joe McDonald:Otherwise, then it's kind of countering some of those things with massive curiosity and very low ego. And even we have to run this as founders, right? We have always said from day one, the mission is more important than us being in the seat we're in or having control of the teams that we have. So by bringing in that low ego, I think you create a much stronger overall unit case because then you've got lots of owners, but they're willing to think differently, not assume they know the right answers. And they are able to, with positive friction, work with everyone else to kind of compound and help solve problems at a faster rate.

29:17Joe McDonald:Like that's ultimately what we're looking for is I have a very fast growing company that has an exponential increase in problems being created and needing to be solved. So what we need to find is a way of organizing people and systems to meet that exponential curve. Because if that gap grows too wide, then obviously you're going to have to either slow down growth, which is really painful, or you're going to increase growth and become terminal because in two years time, you just haven't built foundational level thinking system that can really solve the problems and provide all the benefit to the customer.

29:45Joe McDonald:So that's kind of what we look for. Ultimately, in terms of finding these people, again, it's time and quality. So my experience has been if you meet someone, even if it's like just serendipity, you know, you just meet them in a room and you have a moment of like, wow, this person has some of this kind of raw skill set. I find a way to get them into the company. I don't worry about the title. I don't worry about the salary. I just worry about like pitching them the mission, the vision, giving them the problems and seeing if that excites them. And the people who run towards those problems have become my best hires ever.

30:16Joe McDonald:You know, my original CMO is now our kind of CGO, CRO, right? She hadn't necessarily done full go-to-market before, but she's exceptional first principle thinker. She is a category creator and she was able to build on the cutting edge of what is now a new way to actually build go-to-market motions right so that has been like the best payoff of any hire i've ever had and that's happened now a few times the rest of it is tough though because you have to throttle and we're having to think about new ways of hiring you can't necessarily have a linear kind of factory line of hiring you need to think about how do we go out and run events where 20 engineers turn up and we hire 10 of them on the spot right after two days of like hackathons over the weekend or something rather than this idea of one by one engineers come through and we have a 75 rejection rate which then means our current best performers are being slowed down by having to interview loads right so we're always trying to find the right frictions of quality and speed it's fascinating

31:06Adam Chirkowski:to hear and really appreciate and i'm sure our founders listening to this will be taking notes the ego point though is also relevant for the founding team the reason why four actually worked because all of them just left the ego at the door from day one. It was always very honest, transparent, which for me is key. Joe and the team are not trying to feed me all the sugary good stuff. That almost gets put to the side. It's like 30 seconds at the start, right? This is what we need help on. This is what we have problems with.

31:40Joe McDonald:There's work going up as well. So the partners that we chose to invest into us represent, it's like a hire for me. and if the board sets the wrong tone and pressure and pace and understanding and cultural misalignment that will feed pressure into the founders who whether they like it or not will be pushed to do things differently in the way maybe they originally intended so we also look up to our board to make sure i went into i think q1 with unbelievable growth we grew more in one quarter than we grew in the last two years right we've done 10x 10x and we're maybe going on for 10x again this year and we scored ourselves a four out of ten and i feel confident enough to go in and tell the board these are the problems in the same way i've given you the problems that you need to help me with rather than like here's my pitch and here's my how's everything's rosy so having that and that kind of transparency and trust is vital both up and down i think as a founder it's not to be

32:29Adam Chirkowski:underestimated who you take on this journey 100 that clearly you have an incredible partnership the fact you're here talking about your experience of scaling this business together is a great sign and something that i think founders obviously when you're fundraising it is hard and you are looking for people to invest and come on that journey but you also shouldn't cut corners in terms of who you get into bed with and make sure you've done your own due diligence you get some on the

32:52Joe McDonald:paddle court oh i like that high rocks whatever it might be oh really take people out their comfort zones i don't know no to be honest he took me for dinner i was like oh that's nice okay good to know

33:01Adam Chirkowski:paddle okay jason on the other hand yeah buy him dinner and he's golden yeah i have to be very very careful i love that we're coming towards an end but for any early stage founders we'd just love to give any other advice when it comes to hiring and maybe one hire that you wish you'd have made sooner that maybe you put off for whatever reason is there anything that others can learn from your

33:23Joe McDonald:experience yeah i think general advice would be don't listen to advice listen to shared experience like listen for the other experiences that that other founder or advisor or investor might have actually had to make it relevant what they're telling you because i think i spent too long listening to advice and trying to reflect that back and missing out that they were doing something completely different to me and had a different vision, a different outcome. So that's just generally off the table, look for those shared experiences. I think the two areas on hiring, certainly the role I wish I'd hired earlier was now thinking about the individual that can build this intelligence layer in a business because it's very, it's technical, it's operational, it's data, and then it's layered on with a hell of a lot of empathy about how you build your kind of coaching and performance structures, right?

34:06Joe McDonald:So your people partners of the past or your heads of people, your HR, they might have the idea of like how to do a performance-based culture, but they have no idea how to translate that into like a talent-based kind of AI system for this kind of modern stack company. So I think finding those people, there isn't a name for them yet. So it might be the chief of staff getting that earlier than you wanted, or it might be the founder associate, or it might be the in-house engineer who just loves the idea of building like coaches for the staff. I really wish I'd invest in that earlier because documentation and process and data, trying to unwind that and bring that up slows you down so much.

34:40Joe McDonald:Whereas if you get it right from day one, it's massively, massively helpful. And then I think it's recognizing when you're going to have the really tough hires. I don't know if there's another way around this, but I reckon there's less than 20 CFOs in the entire world who are right for our company. And you can't expect them to find them in a month because you're looking for the timing of the window to open up. So you've got to be thinking about how do you build teams to be self-sufficient, potentially without those real like superstar leaders to give yourself enough time in the market to like ships crossing at night eventually right time right place right person and then i think you know that's tough because i'm under pressure from the border like we're growing so fast and get a cfo but equally i know bringing the wrong person in probably damages the mission more and that's seven months of work already today to find that person yeah it's just persist just

35:27Adam Chirkowski:at the end of the day it's just be resilient yeah yeah and resilience is the probably the most common theme that comes up on this podcast i'm going to shout out one of your early hires that changed my life from getting information from you which is court i mean jammer as well but one of the earliest just someone that can clear your mind space and just deal with your life

35:49Joe McDonald:i think revolutionized you way back when yeah so courtney is my ea and she was actually ex transfer wise and worked with the founders there so i'd seen what journey she'd gone through and the kind of culture you'd operated in. And yes, Claude can basically be my mini chief of staff, can manage my diary, can tell me what I need to look at. But there is a having someone who can compound my human aspects and allow me to do more as a CEO and take a lot of that weight away. And actually, she builds that chief of staff and she manages that. It just frees me up. I actually think probably that was under the advice of you guys.

36:23Joe McDonald:We got someone like that early enough. And I do see a lot of founders aren't willing to because I think they feel it's embarrassed, like the idea that they can't do the whole job themselves it's a failure to hand that over and delegate that to someone and I do think you can get the wrong person as well I don't need a personal system right my life can just about run because it's very simple I get up and I run the business and I go to sleep and I think about the business but like finding someone who can actually be that extender of what I'm trying to do and how am I trying to operate in the business was like such

36:49Adam Chirkowski:an amazing heart that's great advice thank you before we get to our wrap-up question looking ahead I know everyone here will be excited to know about the future for Tem both in terms of the short term, the next 12 months and longer term. So tell us a bit about that if you don't mind.

37:02Joe McDonald:So I think we've gone in two years of operating, we've gone from zero to about 6 ,000 businesses that are now transacting with us. We'll be closing, as I said, about a billion pound of annualised revenue flowing through the transaction infrastructure. That's just in the UK. And I think the reality is we come back to some of the kind of other points we made earlier. Our North Star is transaction fees saved for businesses, literally dollars put back into businesses pockets. And so we look at that and we're like, wow, like 50 million, that's amazing. And there's real life stories there. And then we look at the percentage against the global transaction fees and it's 0.0013.

37:37Joe McDonald:So it always makes us realize like our journey is only just getting started. So when I think long-term, 10 represents a solution to one of the three pillars of bringing down the cost of the electron to like close to zero and ushering an entire new kind of industrial world, very similar to what happened with compute. And we feel responsibility for doing that at the transaction level. And that's our core focus is to do that across the world in every market, providing that nucleus and backbone in infrastructure. No dissimilar to what Stripe has done in the payment sector. In the short term, it's just prioritization.

38:07Joe McDonald:We're getting pulled everywhere. We've got internationalization. We've got companies coming out wanting third-party access. There's a lot of trade-offs that we're trying to make in terms of where's the next bet, whilst also still growing our own stalking horse in the market that's moving at a million miles an hour. So I think the next 12 months is about picking that next market, proving the interoperability of the platform. And in reality, our mission is to bring well over 100 new utilities to market in a market that's had no more than 30 in 30 years. And that for me is that step change of like, wow, there's a different way now to serve businesses and usher in a kind of a new ecosystem into the UK market and then hopefully a couple other markets around the world.

38:43Adam Chirkowski:Love that. Very excited for you. What is one final piece of advice you'd like to leave founders listening and watching today whether it's career life advice will come to you first i think really understand your value proposition and who is valuable to really understand the customer and what you're delivering and then fundamentally it's just execute it's execute execute execute i mean more and more moats right get eroded very quickly technical moats and defensibility a lot of it just all roads lead back to the founders and their ability to execute and stay ahead. Love that.

39:21Joe McDonald:Thank you very much. Enjoy. Part of me wants to say everyone looks better than they are. And whatever you think you're suffering with, or your business isn't growing fast enough, or like that comparison, I think is really dangerous. I think if you just truly believe passionately about solving that problem, that's all that really matters. And some businesses compound a lot slower and become huge. Some businesses go very fast and then blow up. So I think to stop comparing myself was probably to everyone else and even getting off the LinkedIn and Twitter threads and just being like, no, focus on what matters to me.

39:51Joe McDonald:And then I think kind of what links that is the why. Like really don't hesitate to keep going, why am I doing what I'm doing? And having that with your co-founders or with your business and even over your strategy is so important. That aligning on the reasoning on the why, I think then really empowers you to make the right decisions moving forwards. Everyone seems to focus on how, how are we going to do this and what is the right strategy, but why are you doing it? I think serves an incredibly deep question that as a founder team we consistently go deeper and deeper on every single kind of quarter about what motivates us and what gets us up in the morning to do the job that we're trying to do.

40:25Adam Chirkowski:I love that two very inspiring answers having a strong purpose focusing not getting distracted and having the relentlessness to get through the harder times to achieve your potential I think is a brilliant place.

40:37Joe McDonald:One more thing as well because I hear it a lot be really ambitious the UK founder ecosystem is built around the idea of success in the UK which previously was sell your business for 20 million, get a knighthood and everything looks great. Right. And that's different if you look at the West coast. Yeah. They're about changing the world and being fearless on dominating that perspective and being really aggressive in what you believe. And we have the talent in London. That's why people are setting up all of their engineering systems and R and D systems. And the one thing we're missing, I think, is that level of like ambition and fearlessness and whatever failure risk is gone because they're looking for asymmetric.

41:12Joe McDonald:I hope more founders feel like they can be confident in making those grand statements and utilizing the UK for what it is, which we have unfair advantages in creating generational companies. We've just not done it at the scale yet that I think we're about to.

41:24Adam Chirkowski:I cannot agree more. And don't let perfection kind of be a barrier. Just get out there and do because no product or anything that's built, especially a V1, is perfect. If you keep trying to make it perfect before you actually get it out there, then you won't get it anywhere. that is the perfect place to end what has been a brilliant genuinely inspiring entertaining conversation so thank you both so much for being fortunate mentors and sharing your mentorship with us all no thank you

From the publisher

In this 40 Minute Mentor episode, we’re joined by Joe McDonald, Co-Founder and CEO of tem., and Adam Chirkowski, Partner at Albion VC, to hear the unfiltered story of building one of Europe's fastest-growing energy companies and what it really takes to back, build and scale a mission-driven startup.

Joe has spent over a decade in the energy industry and has seen first-hand how broken the infrastructure underpinning it all really is. After selling his previous startup in 2019, he’s back in the Founder seat building the fix through an AI-native energy transaction infrastructure built for the way modern businesses actually operate - from Premier League clubs and Formula 1 circuits to local cafes and independent retailers. 

Adam was one of the earliest believers, spotting Joe at an online demo day and backing the team before almost anyone else would. Although ultimately a generalist investor, he has a particular focus on EnergyTech and has invested, advised, and sat on the board of companies across a broad range of sectors, including raising and deploying over £150m of funds into Renewable Energy. 

Together, they share a candid and honest account of the inception moment that launched tem., the early mistakes that nearly derailed it, the philosophy behind closing a $75 million Series B in two weeks, and why Joe spends 70% of his time on culture. 

Whether you're a founder, operator or investor, this episode is full of hard-won lessons on hiring, fundraising, mission, and what it actually looks like to build a generational company.
