When YC began funding hard tech companies, the idea was widely ridiculed. Accelerators were associated with websites and lightweight software, not synthetic biology, nuclear energy, quantum computing, or fusion. Founders were told YC could not understand the technology and that its model could not work for companies that needed years of technical progress and substantial capital.
The first lesson is simple: it worked. Companies including Ginkgo Bioworks, Oklo, Rigetti, and Helion showed that startups could bring genuinely difficult technologies to market. The investors did not need to tell founders how to build a fusion reactor. Their role was to find exceptional builders and help with everything around the technology: forming a company, recruiting, setting milestones, and raising capital.
Difficulty can itself be an advantage. There are many people competing to build straightforward software products. Far fewer people are both qualified and determined to start a quantum computing company. Chad Rigetti’s YC Demo Day slide captured the idea as a Venn diagram: people qualified to build a quantum computer, people who wanted to build one, and Chad at the intersection.
The same pattern showed up with OpenAI. A small nonprofit research lab trying to build AGI looked implausible beside Google, which had the researchers, data, money, and computers. The ambition attracted unusual people precisely because the idea seemed unreasonable.
Funding one ambitious company also attracts others. Early aerospace and deep-tech founders had few places to go for seed financing, so each serious company made the community more useful to the next one. That remains part of the model at Standard Capital: bring together founders solving difficult physical and technical problems so they can compare notes with peers who understand the work.
Ambition is not enough. The hard-tech founders we want to back have a path from here to there. They can explain what they can deliver now, what the next capital will prove, how the company can scale, and which risks they will remove along the way. “We are going to do this impossible thing” is not a plan.
The central financing lesson is that hard-tech companies are built through a series of miracles. Software companies can often raise against revenue and growth. Hard-tech companies must choose technical or commercial milestones that make the next financing possible. Each round should fund a specific proof—not the entire end state.
Tesla did not begin by asking investors to fund the complete future of electric vehicles. It proved the Roadster, then the Model S, then the Model 3. SpaceX proved one impossible step after another, including turning its satellite network into Starlink. Each result made the next one more believable.
Hard-tech founders should not expect investors to recognize the full brilliance of an idea and finance it all at once. Set up the next proof, perform the next miracle, and earn the right to keep going.
