Key Themes and Discussions

Oskar Hartmann's Journey

  • Background:
  • Oskar is a legendary operator who has built and exited over 10 companies across various countries including Germany, Russia, Japan, and now Dubai and Silicon Valley.
  • He has invested in over 150 ventures, including 14 unicorns.
  • Transition to Angel Investing:

"Beast Mode" Philosophy

  • Definition:

  • He contrasts this with the need for work-life balance, particularly as a parent.
  • Importance of Meaning:
  • Emphasizes the necessity of having a purpose or "product-soul fit" for sustained motivation and success.

Challenges in VC and Entrepreneurship

  • Adverse Selection:
  • Oskar highlights the challenge of adverse selection in venture capital, where investors end up with subpar companies due to poor selection processes.
  • Community Over Individualism:
  • Believes that enduring success stems from communities rather than individuals, advocating for collaborative approaches in investing.

Accumulator

A New Angel Investing Model

  • Concept:
  • Accumulator operates on a share-pooling model aimed at mitigating concentration risk for founders and angel investors.
  • Investors can pledge equity in one unicorn company to gain access to a diversified portfolio of other unicorns, enhancing liquidity and investment opportunities.
  • Community Engagement:
  • The community of investors serves as a gatekeeper for selecting companies, fostering a sense of shared responsibility and accountability.

European VC Landscape

  • Need for Growth:
  • Oskar argues that Europe requires not just more unicorns but deca-corns and hecto-corns to avoid losing valuable entrepreneurial talent.
  • Serial Entrepreneurship:
  • Encourages a mindset where entrepreneurs continue building after achieving initial success, rather than stopping at their first billion-dollar valuation.

Personal Insights and Lessons

  • Building a Network:
  • Oskar shares his experience of networking, engaging with over 500 top-performing angel investors to establish a robust community.
  • Learning from Failures:
  • Reflects on his past failures and how they have shaped his investment philosophy and strategies.

Key Takeaways

  • Sustainable Entrepreneurship: Balancing work and personal life is crucial; "beast mode" should be tempered with a sense of purpose.
  • Community Power: Engaging with a community of like-minded investors helps mitigate risks and enhance the chances of success.
  • Innovative Models: New investment models like Accumulator can revolutionize traditional approaches to angel investing by focusing on diversification and liquidity.
  • Continuous Growth: The European VC landscape needs to support founders in pursuing larger, more ambitious goals beyond their initial successes.

0:00Welcome back, everyone, to another episode of the UBC Podcast. I hope you know by now that this is a place where we try and reshape how starters and companies are being built and funded. Today, we're joined by Oscar Hartman, a legendary operator turned super angel. From building and exiting companies in Germany, Russia, and Japan, to pioneering one of the most novel angel investment models I have seen, Oscar is flipping the script on early stage capital.

2:17Tear down this wall. It's more than just an alliance. This is a union of values. Let's start acting. This show is not investment advice and the hosts of this episode may be invested in the funds and companies featured. Welcome to the podcast, Oscar. Yeah, thank you so much for having me, Andres. So, Oscar, let's start right with your focus on or your commitment to relentless focus. I want to ask you because you've said the founder mode is beast mode and you've built more than 10 companies from zero to exit in 25 years. It's not just a mindset. It's a way of life. What does beast mode really mean to you?

3:03I'm still waiting to meet some people that can teach me how to be balanced and have high achievement at the same time. I have not met them so far. I have met Martin Warshawski. I think Martin Warshawski is the best example. he built five unicorn companies and he has seven kids and is a like a family man but what he does is alternation so he goes to beast mode to the u.s for two weeks and then he goes back to the family and he just like alternates between the two which i think is a good model for later stages he's he's more older than 60s i think but when most people i see that build unicorns they are definitely i'm not i'm not sure if it's beast mode or something but if you count the hours it's definitely a lot so yeah that's the only way of life i have scenes of these scheduled meetings saturday evening they schedule meetings on their birthdays they do zoom calls on in their wedding you know like who does that tell me oscar though you've you've you've been on that journey yourself let me hear a bit about and last time we spoke you know you said well right now i'm in a place in life where I have small kids.

4:18So I'm trying to live life differently. And for that reason, I also am focusing right now on investing rather than building. Talk a bit about that. Yeah, basically I was burning out every two years or so, meaning that, you know, you have to go to the hospital, you get like, you have like health care because your nervous system shuts down or something like that. And then you come out and you go beast mode again and then you burn out again and then you it's never maybe that's normal maybe that's the cycle of life but uh yeah it was definitely the worst year for me was 2013 i think where you know i thought it's going to be the best year ever because i sold two companies in 2012 i finally had my big exits i sold the company for 75 million and i thought it's going to be the best year ever and it was the worst year ever.

5:13So my expectations to reality mismatch basically killed my brain because it was very difficult to adapt to that mode. I always say founding a company is like having sex with a gorilla. You know, you are not done before the gorilla is not done. So as soon as you are found a CEO, that's it. You know, the thing happens to you. It's just the thing happens to you and there is so much uncertainty and so much unplanned things. So at the moment, I'm focusing on angel investments because I cannot be a founder CEO at the moment for the first time in my life. I have four kids. So I said, okay, I'm going to be an angel for at least seven, eight years while the kids grow up so they know who their dad is.

6:08they know how I look like and so on and then I'm going to go back to beast mode hopefully so that's my model and I think it's a good model I think rarely people do it because if you think about life life is going to be long right yesterday my wife and I we signed a 120 year pact so we want to be together for 120 years which means we have to do biohacking we have to survive the next 30 years and then there's going to be a lot of innovation. And if you think about this type of frame, then taking seven, eight years off as a founder is not that much. It's not that much. You build a family and then you still have 50 years out.

6:54You can still do it like five more times, hopefully. So I want to be like Warren Buffett. I want to sit 95 years old. I want to still, you know, sit there and like give up the CEO role while not actually giving it up, you know. Tell me though, tell me, just give me some value judgment here, because there's a lot of conversation, of course, around where the 996 and beast mode is sustainable. Is that something that we should be actually saying to our founders that they should go for? And this is the model. this is what you got to do? Or is there something to more work-life balance when you are a founder in a venture-backed startup?

7:40Yeah, I think what is much more important is that people don't stop. Because what happens with 996, a lot of times, people burn out and they never come out. So basically, the midlife stage, like at the age of between 35 and 50, A lot of people have their peak achievements already behind them. So nothing much happens after. And that's a huge loss for humanity. Because these people, just like Martin Warshavski, he's 67. He's disrupting the fertility market. 300 ,000 people were born in his clinics that would have otherwise not been born. And this guy's on a mission, right? And we would not have him if he had burned out at 50 and said, basically, that's it.

8:34Now I want to enjoy life. So the most important thing is we need more entrepreneurs who, after achieving success, keep going. They just keep going and keep going and keep going. You know, there's so many examples. I just spent five weeks in the Silicon Valley. I met like four or five 60-year-old founders who are still building stuff, making things, and they don't need to. If you take the top 100 people in history in science, top 100 in entrepreneurship, top 100 in influence, they have almost nothing in common. They're very different people. But they have one thing in common. None of them stopped.

9:19But they were at their thing until the last days of their life. There was no pension in this group of people. So I think that is the most important thing. And this 996, this goes hand in hand, Andreas, with meaning. There's two types of 996. One 996 where you actually have answers to the why you do this and what is your long-term vision. And it's aligned with you as a human. you have founder what i call everybody's looking for product market fit i'm always looking for product soul fit is this company your soul's purpose you know then 996 is not the problem it's easy easy but people lose meaning and when people lose meaning and they just grind it out they don't they don't know why they're doing it i think it's okay for your first company or so you You know, when you're still young, when you're still figuring out how you, what you are and you're trying things.

10:21But 996 is really easy, really easy. When you are a man on a mission, when you have the project that you are building with your own hands, that you believe is, you know, helping people, bringing joy to people, bringing solutions to people. It's very easy. But when you don't have that, for example, I didn't have it when I was building factory market in Germany. We were building a cross-border marketplace where Chinese factories could sell directly into the European market. And we grew up to 2 million orders per month. But I was in my biggest midlife crisis ever because we were basically selling trash.

11:07The average order, we were basically competing with, you know, like the likes of what is called Temu now and, you know, Shein and AliExpress. And our average order value was like€3.50. And there was a package flying from China to Europe. And when my team created the pop-up store for me with all our best sellers, they wanted to make me happy. And when I entered this pop-up store, my brain said, why are you spending your life on this? Why are you spending your life doing this? That the bunch of useless shit, 5 million products per month fly through the air. Yes. So that is where you really burn out, Andres.

11:59It's like when I do entrepreneurship development, I'm doing entrepreneurship development since 13 years when I created my first scholarship program. I never burn out doing entrepreneurship development. I think that is very important. It's much more important. The technical 996 is not important. What is more important that we have people who become serial entrepreneurs, who keep scaling? Because as you know, Europe doesn't have a problem with unicorns. Europe has a problem with deca-corns, hecta-corns and giga-corns. Because a lot of people just stop, Andreas. They just stop. They say that's enough.

12:38You know, a billion is enough. And then they stop. And then after that, nothing happens. And that's where we lose, that's where we lose so much talent that is so scarce that it makes me, it is very painful for me to observe. I think we lose like half of the founders at the midlife point. Oscar, you've said a bunch here. I think that it all deserves the context of your life, so to say. So let's just talk a bit about your journey. Take us through, you got out of college. What do you do? My first part of my story, I'm a never-ending immigrant. So I was born in Kazakhstan. We moved to Germany when I was seven.

13:21I moved to the US when I was 17. And I just kept moving kind of because I just like this immigrant lifestyle, I guess. I just keep moving. I spent the last seven years in Dubai thinking to relocate to the Silicon Valley. I'm German by blood, if you can say that. And then, you know, I wanted to be a scientist. Physics was my favorite subject. And then I figured out that the people who actually make decisions are entrepreneurs and people who did economics. So I studied at the WHU in Germany, which is a fantastic school where 25 % of all German unicorns came out of this small school, which is quite incredible.

14:04Yeah, basically the only company I ever worked for was Boston Consulting Group. And other than that, I created my first online shop when I was 18. When I came back from the US to Germany, I created the online shop for fitness products, which was the same as bodybuilding.com. I thought that this business model is not very scalable and switched to construction products. So I actually closed the successful online store. Later, Protein.com proved that this business model is scalable to like 50 million in net profit per year. I was three years before Protein.com, but I messed it up because I had this immigrant mindset of, you know, like not being able to hire people.

14:48and then I went into online fashion after university because I said oh wow you know I know online you know e-commerce and I did the VHU so I thought I can build a bigger company now what I had in mind was like a five million dollar company because before that my company reached one million in revenue that was where I maxed out and then I said okay I'm gonna build a five million and just I put seven in the business plan because, you know, and it became a$250 million company in four years. So obviously the business model was much better than, you know, than I anticipated. And it just like that. I grew up with this company and then, you know, sold my first online shop for shoes for 75 million.

15:35And that gave me the startup capital to do more things and to start investing. So since then I have participated in 150 ventures that I either co-founded or I was the first investor, the first angel investor. So this 150 business stories, you know, 43 died. They don't exist anymore. And unfortunately, I spent 90 % of my working hours on these 43 companies. like i really that's what i don't want to do in the future like i it's really stupid to spend all your time on on the sick part of your of your life 14 companies became unicorns one billion dollars and and more you know i was very lucky to pick some of the right business models that i could have several unicorns in different countries with the same business model and I still have a portfolio that is quite large.

16:36I think I'm at 91 companies at the moment and I'm enjoying this. Somehow I became one of the top 20 angel investors in the world by the statistics of CB Insights and Deal Room over the last 10 years. And I thought, oh, wow, if I'm feeling so bad all the time and I'm top 20, how bad must everyone else feel? You know, it really sucks to be top 20.

17:06Tell me, Oscar, because you've now taken. So first and foremost, you have a crazy vision of, was it 100 unicorn companies you want to be an owner of? I want to be a grandfather who has 100 stories to tell his grandkids. I don't want to be the grandfather who keeps telling the same three stories all over and over. I want to have a hundred stories that I can tell, you know. So my dream now is to retire at Stanford, you know. I just did lectures at Stanford and it's like the best quality of life ever. So I want to be at Stanford and I need a hundred stories that I can tell my students and my grandkids.

17:49That's my dream. And unicorns are good stories because they are very bright and they are very meaningful. and they touch the lives of thousands of people. And yeah, so I want to build a collection of 100 unicorns. And you make a great point because in the beginning you set out to build a company, then that company reached 1 million. Then you were hoping you maybe built something next time that would reach five, it reached 250 then. And so on, you've continued through your life. And I think one of your learnings, if I should deduct anything from what you've said here is always dream even bigger.

18:28And you can actually do it if you just bring your energy and build in a different way than maybe what most people do. It took me 20 years to realize that I can almost build anything. if it correlates with my meaning that I give life, if it correlates with my soul purpose, there's nothing I cannot build. And it took me 20 years to get there because I was this immigrant child and our grandparents were always telling us, you have to get a good job. That was like, you have to get a job. And it takes a very long time to... And I think a lot of people, I see some people do it faster. They're like 29 years old and they already dream big and they set big goals.

19:23And I always wonder, there was this Indian entrepreneur pitching me in the valley and he was like 29. And he pitched this crazy vision. And I was like, what is it about this guy that makes him believe he can outcompete like Salesforce, Microsoft? What happened with this? It's always a very interesting question. How can you get to that mindset faster that all the people who change the world are not better and not worse than you? they are the same. Yeah, they just work very focused. Tell me, Oscar, because what you've then dedicated this next chapter of your life to, so to say, is reaching those 100 unicorns.

20:16And you've then looked at the angel model, the venture model, and said, this is how I'm going to do it. Take us through that analysis because you've ended up building something that I have never seen before. And I think a lot when they hear this, they'll be like, huh, that's an interesting model. Yeah, by unique experience, maybe it's how can you turn pain into pleasure? I lost more than$100 million in equity value more than three times. So more than three times, I had equity worth more than$100 million that evaporated because unicorns, they are born and sometimes they also die. And every time that happens, it's very painful.

21:03Sometimes there's people who have only this equity. So I saw people that had literally all their value in their life in one company and then just evaporates for all kinds of different reasons where I believe 75 % are outside of their control. So that was the first life experience that I had. The second life experience that I had was how difficult it is to become shareholder at any unicorn company. It's almost impossible. Almost impossible. It's like literally one in a million companies. And if you just invest in Stanford companies, then it's one in a thousand. It's one in a thousand if you just invest in Stanford graduates, you know.

21:49so it's very so most of angels and most of founders they see one unicorn company throughout their life it's literally if you take the top one percent out of them 99 will only see one unicorn outcome whatever that means to you in during their lifetime so that is a very big so it's almost impossible to find one two martin warszavsky with five it's like top five in history of mankind. Yeah, a lot of investors get very frustrated because they become angel investors and then they see only one unicorn company. And the reason why they invest is they want to be part of more than one thing, right? They want to experience it.

22:33So I said, how can we solve this problem? How can I solve it for me? And how can I solve it for others? And the final click came when I saw that there were$5 trillion of unicorn equity and only$50 billion of secondaries a year, like two years ago. So there was less than 1 % of an asset class that is$5 trillion that was actually liquid, which is like, and a lot of people see that, right? They have no liquidity since 2022. and I said wow we need a liquidity platform for the unicorn asset class and that will allow all of us who have equity in unicorns to solve liquidity but also to become shareholders of more success stories so I created a share pooling fund where you can become an LP by pledging equity in one unicorn company against a portfolio, a very diversified portfolio of unicorn companies.

23:39In order to make this work, I created the community of the best unicorn founders and unicorn angels. We created the community first and the community is the gatekeeper of the fund. We decide as a community, we select the companies that we would like to approach with this offer. Then we proactively approach and say, hey, you have$100 million of equity in what company won. Do you want to use some of it and become an LP in a portfolio of equally great companies? It's quite a good value proposition to a lot of people. So we are at 300 million AOM now with zero cash. So basically, we pool, and then whenever we have an exit, we share the proceeds, right?

24:26We had our first exits now and we share the proceeds. So it's improving liquidity for everyone. And now we have also cash. We can also give advance cash, liquidity. Every time somebody joins, we can give up to 20 % cash. And tell me, do you approach investors in unicorns or founders as well or only founders? We approach private people who are not funds. So it could be an angel investor, the first angel investor or the founder. There's more angel investors than unicorn founders. So I would say it's 60-40, 60 % of the people are early angels and 40 % are unicorn founders. Unicorn founders have a much higher concentration risk usually, right?

25:15They have usually much bigger equity packages, not diversified. And also unicorn founders always believe that their unicorn is the best of all unicorns. I think angel investors are very easy to convince that diversification makes sense. All of a sudden, you own 30 million in Rippling or Canva or whatever great company. And then you say, oh, I'm going to take 20 % of my stake and do secondaries. and I want to take 20 % and put it into a diversified fund of private tech companies. Tell me a bit about the analysis that kind of got you started on this journey because I think you made a pretty interesting one.

26:05Yeah, I mean, there's analysis and what gets you started, Andreas, is always emotions. So the emotion was, I will die and I will not achieve my dream. That was my first emotion. The second emotion was, if I want to achieve my dream, I need to do 1 ,500 investments like Fabrice Grinder. And that means I will have 400 bankruptcies. Way to play rounds, founder fighting. Like when I thought about this, my head exploded. I'm like, there must be a better way. that is statistically what i would have to do with my current track record to achieve my targets and the last emotion i had was the emotion of i have a never-ending fomo like in ai now how can you know it's so painful you're not there and you're not in this and everything is growing all these important companies are coming up and you want to be part of the important companies of the decade, right?

27:12If you were not part of Airbnb and Uber in the last decade or before that. Yeah, so FOMO makes me sleep really badly. So I said, I want to sleep well at night. And the only way I can sleep well, if I have a portfolio of 150 companies that all have a good chance, that means they are already at a billion and they have a very good chance that they will become the most important companies of the decade. to come yeah so that were the emotions and the analysis obviously everybody knows the numbers we have 1500 unicorns in the world out of which half are not really unicorns they are corpses or fake unicorns or dead zombie corns there's something else but there's about 750 companies a lot of which have been funded in 21 that have raised too much money that have raised more than a billion dollars if you raised more than a billion dollars and you are unicorn it's i guess it's not the big achievement in terms of value creation and there's a lot of companies that have almost no revenue and now you know almost so there's a lot of buy and build type stories all of a sudden vcs thought that they can build companies and drive them to ipo they don't need founders anymore.

28:35So there's a lot of this VC type made for IPO companies that have no real founder. So the remaining 750 are really, really valuable companies, I think. And we don't know. The sad part, Andreas, the saddest part of my analysis was me understanding I cannot predict which of these companies will become HECTA and which will become GIGA and you can sometimes predict which ones will be wipe out right I kind of predicted the you know wipe out of VFOX and some other companies but it's easier to predict the wipe out than to predict who's gonna you know who's gonna be irrational enough to be like Brian Chetsky from Airbnb this guy he's at 150 billion and he's saying for us at Airbnb, it's day one.

29:32We are a startup. We're going to grow 10. Like what is inside this person's mind? Like where? 150 billion he's claiming it's day one, you know, so. Then tell me also because you have a very special approach to how you use the community. It's not just Oscar Hartman's fund and you just do your own thing and you employ a bunch of principals, but rather you employ the community. Yeah. So I think I just saw 150 stories. That's not even scientifically enough to make any conclusions. So I get at people who made more than 10 ,000 investments all over the world and collectively have invested in more than 300 unicorns.

30:22And we built a community first before we started to do anything. And luckily, you know, people like Fabrice Grinder joined, and then Stefan Glentzer joined. We had like the, in Germany, we had Philippe Dames, Philippe Meerman. We had the amazing angels from the top, Avishai from Vicks in Israel joined, and then Jose Marine from South America. And all of a sudden, we had this mastermind that had like a collective wisdom to make decisions. And I have only one vote in the entire community like everybody else. The only people who have two votes are the people who are already LP. They have skin in the game.

31:07They have skin in the game. I'm also an LP, obviously, and then that's why I have two votes. And the community idea is very simple. when you look back and reflect on your track record, what you realize is that not people become successful, but communities become successful. So I was in my life part of some bad communities and some good communities. For example, when we were immigrants, we had this weird community where we would fight all the time. And then, like, people would literally call and tell the location, and you had to run there and fight, not even knowing who is wrong, who is right. And the culture of this community, I realized that this is going to end badly, like my grandmother used to say.

Read the full transcript

32:04And so I left. I left to the U.S. And the members of this community, they ended up in a very bad place. Most of them Then I went to this WHU community Which was for me Very surprising That I was able to get into the school And all of a sudden I am the first Investor in 10 % of all German unicorns And given How difficult it is to find Even one unicorn How can you be how can Oscar be, you know, 10 % of all the great companies that came out of Germany. I was one of the first investors. And then I looked at my email because I've saved all my emails in my life. And I looked it up. If I had invested in every introduction that came from WHU, I would have been in 20 % of all German Unicom.

33:07And then I did an analysis that I would have made more money by indexing VHU introductions versus my cherry picking. And, you know, that is very sad because obviously my decision-making skills are not good. Then I said, okay, what should I do the next 10 years? Because now I need a community, a global community. Where's my community? Yes, I'm part of Founders Forum and I'm part of some great communities. but I was like, okay, I need to build a community of people who share a dream to be shareholders of multiple unicorns. There's not that many. For most people, one is enough. They're like, I'm done.

33:54You know, I always have this discussion, Andreas, when a company reaches a billion dollar in valuation, the founder a lot of times wants to exit. A lot of times, one billion is kind of the dream and that's it, right? And every time I'm trying to convince not to sell. Especially when we had Flaschenpost, Andreas, can you imagine when we sold Flaschenpost for one billion? We were only covering 20 % of Germany. so we were we were not even available in in 80 of germany cities so you can grow 5x without changing a single thing you just do the same thing five more times but the founder was like no i'm selling let's see yeah yeah so anyway so most people don't want multiple and i think the people who do want it they should unite and we share a dream and we want to learn from each other we want to help each other we want to help each other make better decisions by sharing knowledge from practice so we do about 12 events a year one event a month where we meet up and we discuss everything around unicorns, unicorn building, unicorn investing, and all the topics around.

35:21You can probably hear that Oscar is a bit of a machine, but when Oscar set out to build this community, he built a list of 800 global angels that were top performing. And then you personally met with 500 of them and you handpicked the first 50 to join the community. Take us through that process. What you learn, kind of some profiling stuff here, maybe also on what makes a top tier angel you know i wrote a book that's called just do it i'm not sure if i can say this word but uh maybe you definitely can it's door-to-door sales at the end you know when you have a product that is good yeah you have a target list of maybe 3 000 people that this is relevant for in the world that's it you know it's very easy to imagine that you can speak to 3 000 people in about five six years personally personally right it's not impossible yeah so i guess my idea was to just go out and yes to speak as many as possible we reached out to everybody we just found their contact details and then first we sent an email then we sent the whatsapp whether we sent the present to the office, then we try all different ways.

36:39Obviously it helps that I have a, you know, some people know my name because of the things that I did and, you know, it helps to open doors and introductions. It's not difficult, Andreas, like speaking to 500 people, it's not that difficult. It's like, you know, five a week or, you know, seven a week. and if you look at your calendar and there's all this stuff in there, board meetings and this, and then all of a sudden there's a one-hour call with Martin Warschavsky or one-hour call with Stefan Glenza or with Vick, you are like, you know, like it's the most inspiring meetings because these people tell me about how to build a university, how to do impact investing, how to solve the bigger, which problems they care about, why they care about them.

37:32I could write like three, four books just from the 500 conversations I had. It's not, in this sense, I'm not selling a vacuum cleaner, right? Going door to door and showing a vacuum cleaner. This is my passion. This is my dream. This is what I do. So it's super easy. It's not grinding. It's not, you know, it's very pleasurable, very, very inspiring, motivating challenging to you because you discuss is this a real problem or not can it be solved or not who should solve it and these discussions are just so amazing right yeah i would do it for free all day long oscar you're you're you're preaching to the choir i've done 550 podcast episodes now so so completely agree i got you 100 it is uh these conversations i get up in the morning for exactly exactly you lost all your hair doing all this podcast yeah man i don't know if it was my kids or if it was this maybe a mix of european vcs and my kids that made me lose my hair do you measure your stress level in your watch i i deliberately don't i have i do have a smart watch but i only use it i only use it to to measure my sleep because it does remind me that i gotta sleep a bit more yeah but it's interesting to see are is your stress level higher during the week or on weekends.

38:55I have some weeks where my average stress level is like 55 and then I have two days with the kids and the family and my stress level is like 70. Yeah. My wife's watch does measure her stress level. It shows exactly that always. I'm like, nah, I don't need that in my life. Oscar, on the power of community, let's just touch on your India story because I think it's another great one that proves just the importance of community. I made seven investments in India pre-seed, and four out of seven became unicorns. Okay, Cars24 and Spini were both in the used car auction marketplace. This is a business model I know very well.

39:36So I invested in the Carvana of India and the Auto1 of India. My first investment was Fashion and You with Harish Bal, because he did the same businesses that I was doing, just in a different geography. and that was my entry point to India. And then I saw there was the Forbes article about the most successful angel investors in India. There was like a list of 50 people and the most successful had three unicorns and I had four unicorns in India. I said, how? I mean, I was not angry that they missed the German guy. I mean, I guess it's not fun to put a German guy on the top of the list, But I was like, how is this possible?

40:20These people spent all their life in India. They put all their passion, all their work in India. And the only reason this is possible is because of my entry point to Harish. And then from there, when I started investing in India, there was only one unicorn. And now there's 150 unicorns in India. and if you map out how you know the new unicorns are founded by alumni of the former unicorns and if you map out a social network you find that it's a very small group of people very connected to each other that build all these things so i was just like randomly got into the right like the lucky point was harish and then from harish it was like okay then i had two in used cars and And then from that point, you know, I could make some other investments.

41:17One was NinjaCard and one was Slice, which randomly became one of the biggest new banks in India, even though it was an expense sharing app for students. So it was an app for students where they could split bills. And for some reason, they are now, you know, one of the top three new banks in India. It's incredible. What can you learn from this, Andreas? I have not analyzed enough yet. Either this is the last... No, I think you can learn a bunch, right? I think you can learn a bunch. And there's actually the next thing I wanted to go to because what I've kind of deducted is that your core philosophy is that you fight adverse selection.

41:57And you do that by picking communities rather than picking startups. Am I somewhat correct in saying that? Yeah, but that comes after a lot of pain. That is very true. I built an incubator at some point I thought I can build all the companies myself I had created an incubator I was creating one company every quarter and after building 20 and only the first five were successful 15 that followed were not successful because I had adverse selections of 50 the best entrepreneurs in the world just don't come to incubators accelerators whatever company builders, venture studios, you can give it any name you want.

42:44You automatically don't get the best people. There is only one exception, which is Y Combinator, but there were like 5 ,000 incubators in the world and accelerators and only Y Combinator worked. So it's not really a proof point. It's basically a brand that allows people to increase valuation, you know, 5X. and so it is rational to give a little bit of equity to Y Combinator because you dilute less in the steps after. But what I was doing, I was taking 80 % equity. As a result, my co-founders had 20 % and that created a lot of problems for me. When the companies were going through trouble, sometimes the founders would give up and give me the keys and just say, it's your company, you go solve it.

43:32sometimes they would not capture opportunities so at that point i said i don't care how much i own in any company the only thing i care about is that it should become one of the most important companies that's it doesn't matter if you own one two five eight whatever it is you know i was at eight percent and flash and was when we sold it was quite good and i was maybe at the beginning and out of one I had five percent and then a lot of the success stories you know my I might own is you know just one percent and it doesn't matter because you are participating and when you are helping so the most important is to be next to the most exceptional people in the world the adverse selection is the killer of all portfolios you know yeah that's also for us at Accumulator, the number one topic, because we don't want people to bring us their bad apples and swap them against our amazing portfolio, because we have a really very good list of companies.

44:37And so we watch very carefully. So we basically don't look at stuff that comes to us. We proactively go after the companies that we want. The second, we have this community-led admission board where it's very difficult to pass this admission board because we have the specific you know goal to avoid adverse selection and the third is the community why would you give your bad apple to the community of the hundred most influential people in the world right when you can sell it to some dentist in new york or on hive or whatever uh so it's it's it's probably the the last place where you want to bring is you you don't want to destroy your reputation right so that's that's how that's how we set it up but nevertheless Andreas is always, when I speak to founders, a lot of times they think their company is the very, very best in the world.

45:33And it's very delusional because sometimes I see, and like a year later, they wipe out and the founder had no clue this could happen. You know, like no clue. What do you think will happen to all the AI companies? I met like 100 AI companies in the valley. They're all valued like between 500 million and 2 billion or whatever. They all look like serious A companies in terms of risk profiles, stage, revenue. They are more like serious A companies, but already worth billions. What's going to happen to all of these heavily funded companies? That actually brings up an important point that I thought about earlier that I wanted to ask you about.

46:17You come from a company building angel investor background and so do many of your co-investors I imagine in the community because you were all in very early, the majority of you. You also mentioned Christian Meerman and Philip Dames and so on. They're all incredibly good early stage investors but once you're trading unicorn portfolios, you're actually trading late stage companies, what do you think allows you to be successful in this, which is in the undergrowth growth stage play? That's a very good question, right? Of course, we have like analysts who come from this asset class, know how to analyze this and so on.

46:59But I still think that builders and entrepreneurs, builders, people who build stuff to different levels, you know, to 10 billion, Philip Dames, he was co-founder of Zalando, which is, you know, 25 billion. I hope it still is. Maybe it's less now. When you have people like that on board, I think they make good decisions at all stages. So we want people who have skin in the game, who are builders, who know how it is to build stuff. But I guess we don't have a typical, you know, Goldman Sachs, equity analyst type of profile. Our mandate is not to 10x the fund. Our mandate is to not, you know, allow people to not lose all their money.

47:49We are like an insurance policy. We are like a good life insurance more than like if you want to do 20x, 30x, you might as well invest in Sequoia or Excel Partners and hope that they will, one company in the portfolio will be an outlier, right? And then that's a better way to get to, you know, whatever 25 % IRR. We are more a solution for liquidity and for preservation. Which I guess also describes a bit why your problem is adverse selection and why I think you're in correct terms also discussed the Series A lookalike companies in the NAI. that right now look a lot like 501 billion euro. There's going to be so much blood on the streets.

48:41I already see it coming. The reason is it's not because, I mean, they get a lot of funding, which is good, but I just see so many companies with a total lack of discipline in terms of how they spend it, right? And when companies stop valuing money and when they start throwing it around and when they start doing increasingly crazy things that make no sense, you can already see where this is going, right? There's going to be just a lot of... Are VCs making this mistake again because they haven't learned their lesson or is it because we have inherently destructive incentives in venture? In the last 30 years, there were$3 trillion of VC investment globally and six companies returned$9 trillion.

49:34Six companies created$9 trillion value. Then if these were the trillion-dollar-plus companies, then you have companies$100 billion to a trillion, which added another 25%. Then you have DecaCorns, which added another. and unicorns only returned 1.5 trillion. So if you had only unicorns, you would have lost money in the asset class. So what this crazy distribution of outcomes is basically this wealth concentration, value concentration. What this leads to is that the only thing that LPs care about is that you are in the most important companies. like if you miss there's going to be 10 companies that are going to define 2025 2035 and if you miss them you're dead as a vichy it doesn't matter if you invested that 1 billion 2 billion 8 billion it doesn't matter it doesn't matter so that's why all the money goes to this few companies and at the same time the competitive behavior these companies have a lot of incentive to take all this money because otherwise their competitors get it, right?

50:53And then so that's where they basically can dry the markets. So I think it's very rational. What VCs do makes complete sense. It makes complete sense. It was like that since the beginning when I was, when there were only 30 unicorns in the world, when I was a shareholder of Fab.com, okay? And Fab.com had like 12 investors. and when they reached a billion in valuation and they joined the unicorn club all the sudden the cap table was like 120. like there was just so many people just just fighting to get a place in the cap table it was unbelievable unbelievable there was already the very beginning it was already like that so yeah i think the unfortunate thing for entrepreneurship is that less and less people can do more and more and more things at a much larger scale.

51:51So it leads to... And digital business has a lot of winner-takes-it-all dynamics. When you have digital business, at some point, you just get so much for free. It's very difficult to compete. That is very unfortunate. I'm not sure how many companies in AI are going to capture all the value, but I almost would bet that it's not more than 20. not more than 20 companies that will take basically 90 % of all value created maybe less, maybe it's going to be three Oscar, thank you so much for joining me on the podcast, sharing a bunch of wisdom here I think a lot of people that have tuned in today might have had their mind blown on some of the things you've been talking about here, one final question actually, I didn't ask it do you in any way, so you mentioned Philip Dames, you mentioned Christian Miramad Is it only holdings directly in companies that people can get access to your accumulator community with?

52:48Or is it also LP commits? No, we do see some LP stakes because a lot of funds, they go out of business basically, right? And then they don't know what to do with their portfolio. We also look at those. But my main focus is private people who own equity, significant equity. So founders and unicorn angels. Yeah. or incredibly successful early stage VCs potentially. Yes, I still need to meet 500 more. So anybody who feels like chatting with me on Zoom, please reach out. I hope many will. Thank you so much, Oscar.

From the publisher

In this episode, Andreas Munk Holm speaks with Oskar Hartmann, legendary operator turned super angel.

From Kazakhstan to Germany, Russia, Japan, and now Dubai and Silicon Valley, Oskar has built and exited more than 10 companies, invested in 150+ ventures (14 unicorns among them), and today is pioneering a new way to solve concentration risk for founders and angels: Accumulator, a share-pooling model unlocking liquidity and diversification.

They dive into Oskar’s “beast mode” founder philosophy, his candid battles with burnout, the importance of product–soul fit, and why Europe doesn’t just need more unicorns, it needs deca- and hectocorns.

Along the way, Oskar shares his learnings from India’s ecosystem, his obsession with avoiding adverse selection, and his belief that communities, not individuals, create enduring success.
