0:30right. Prompt, inspect, edit, and publish in one place at a whole new pace. So I was new to this whole website building thing, but Framer helped me get set up and running incredibly fast. For instance, I wanted to add a blog to my website. It was super easy. Starting with a basic blog page template, I added some breakpoints and then jumped into customizing my layout, adding my own special touches with Framer's intuitive tools, and bam, I was ready to start letting my thoughts flow. See why thousands are trusting Framer to help build their websites.

1:13That's framer.com slash tcstartups. Rules and restrictions may apply. Andy Elder and Arjun Mather were Stanford roommates who both studied computer science before spending a decade at Palantir. Elder led product design for a team of 800 people building software for U.S. defense and intelligence agencies, while Mather served as a senior vice president in the company's commercial practice. When the friends decided to build a startup early last year, there was no question they would do it together. Despite having no direct background in architecture, Elder and Mather were troubled by a growing problem.

1:54Fewer buildings are constructed in the U.S. today than a few decades ago, as development costs have surged. Mather told TechCrunch, We've gone from dial-up internet to super-intelligent AI, but our ability to build the physical world around us has actually decreased. Believing AI can boost productivity across the architecture, engineering, and construction industry, They set out to build Dream, a startup developing built-world models that automate building design and engineering. Dream has emerged from Stealth with$17 million in seed funding, led by Andreessen Horowitz alongside other backers including SV Angel, XYZ, and Zig Capital.

2:41The startup aims to replace cumbersome, outdated AEC tools like Autodesk, AutoCAD, and Revit. If you sit next to an architect or a structural engineer, you will notice that they are still drawing every piece of their designs part by part on legacy software, Mather says. AI really plays no role in that equation. While a standard LLM like ChatGPT can generate an image of a building, the result will not be structurally sound. Dream, by contrast, is grounded in real physics and construction standards. Just as LLMs learn from text, Dream's world model is trained on more than 100 million square feet of building data gathered from permit archives across the U.S.

3:30Elder said, Our model actually understands what's within those walls, what materials are used, what the beams are made of, and how much weight they can support. The startup calls its approach structural cognition because its model generates structurally precise designs that account for internal building elements like plumbing and HVAC. Dream has already begun selling its product to AEC professionals and developers who use the model to conceptualize building designs and estimate overall costs. The platform is already deployed across 10 active projects in Texas and California. While Dream is not the only company attempting to update AEC software with AI, other startups working on this include Motif, SnapTrude, and Arkel.

4:20Elder and Mather claim that they are the only ones that developed a world model that instantly designs whole buildings. Kimberly Tan, a partner at Andreessen Horowitz, said that while the firm first invested in Dream over a year ago when the startup model was just an idea. She has been extremely impressed with their progress. I have not seen anybody take the technical approach, she said. They're doing everything based on their own models.

4:52Upwind is a San Francisco startup that uses AI to secure cloud infrastructure, and the company has raised a$400 million Series C round at a$3.8 billion valuation led by Bessemer Venture Partners, with participation from existing backers, including Greylock Partners and Kraft Ventures. The round comes nine months after Upwind closed its previous$250 million financing at a$1.5 billion valuation. The fresh funding, which has been in the works for months, nearly fell apart after Datadog attempted to buy the company, according to a person familiar with Upwind. Datadog is a publicly traded company that sells tools for monitoring how software runs, known as Observability.

5:41It did not offer a premium above the$3.8 billion valuation set by venture capital investors, the person said, so Upwind decided to stay independent. Four-year-old Upwind has grown rapidly amid rising AI-driven cybersecurity threats. The startup has been adding$20 million to$30 million in annualized recurring revenue each quarter, and is projected to end the year at roughly$90 million, according to a person once again familiar with Upwind's financials. That means that VCs and Datadog valued the startup at more than 40 times its forecast ARR, a common yardstick for pricing software companies. The high multiple is also well below the 80x ARR fetched by Syara, another fast-growing cybersecurity startup.

6:34Cybersecurity is poised to be the third big wave of AI software that companies will pay for after AI coding tools and customer support. Theory Ventures general partner Tomas Tungus recently wrote in his widely read blog, By walking away from an acquisition offer, Upwind clearly believes that the company will ultimately be worth more than$3.8 billion that Datadog was ready to pay for it. However, given how few cybersecurity companies have gone public in recent years, an eventual sale remains the most likely outcome for the startup. Upwind continues to draw acquisition interest, according to a person familiar with the company.

7:21The startup was founded by Amaram Shachar, who sold his previous company, the cloud spend management startup Spot.io, to NetApp for$450 million. Upwind calls its approach to thwarting threats runtime security, which means it alerts and remedies attacks and vulnerabilities in active services in real time. You've built your retirement nest egg.

8:34Well, here's another early stage agent management startup to watch because of the backgrounds of the founders and the sheer number of big names it has already attracted as investors. Mentif. Mentif has raised$11 million total, including a newly announced $7 million seed led by Cowboy Ventures. Additional investors include KOTU, Operator Collective, and Hustle Fund. Angels include Okta co-founder Frederick Karest, Discovery Loop co-founder and former Google chief scientist Jeff Dean and OpenAI co-founder Andre Carpathy, among others. Mintive is joining a crowded field of products that promise to govern, provision, and offer identity management to enterprise AI agents.

9:21Its platform includes an MCP gateway that allows IT professionals to authorize what the cloud services agents may access and what actions they can perform on them. It also offers an LLM gateway that routes to different models and can cap costs, handles agent identities and authorizations that may differ from the employees that they serve, and an agent monitor that tracks all agents across the company. The company also allows enterprises to create agents that proactively perform long-running tasks. Still, it's hard to imagine a field with more competition. Agent management systems are offered by Amazon, Microsoft, OpenAI, Anthropic, plus as point products galore from companies as diverse as Langchain, New Relic, and Rippling, to name just a few.

10:15Then there are countless startups working on the idea, 40 plus from Y Combinator alone. So, what's Mintive's secret sauce? Given the founders' long history in building AI for enterprises, they have designed their system to be especially easy to use. Setup amounts to clicking a few buttons. Now, the pitch has won over 50 enterprise customers so far, since the startup launched its product back in February. These include Rho, Modern Treasury, the University of Michigan, Coursera, Apex, and Stability AI. But it was the founder's industry experience that won over Cowboy Ventures managing partner Eileen Lee.

10:59She said, AI is going to be able to power incredible things, but we need more infrastructure that's going to give us governance and visibility and control. Lee also says she particularly respects that the company has been careful by only raising $11 million. This compares to other agentic building startups raising vast amounts at unicorn valuations. As just one example, Prime Intellect raised$130 million for its Series A at a$1 billion valuation. That's all for now. For the latest in startup tech news, go to techcrunch.com.
