after reviewing 10,000+ Thiel Fellowship applications, Michael and Danielle developed some pretty unusual ideas about what makes a great founder. edge control. hyperfluency. the toilet plunger. Danielle's "Friday Night Dyson sphere." none of these are a personality test. we're just looking for tricky bastards who always find a way.

in 2019, @Atom_Computing trapped its first atom. 2021: 100 qubits. 2023: 1,180 qubits. 2026: selected for DARPA's final quantum benchmarking stage. we found some photos of their early lab in our archives. pretty cool watching a 1517 portfolio company go from one trapped atom to this.

put a bunch of young builders together for a few days. this is what ended up in their camera rolls. 2E camp 2026.

Phoebe Yao got $1K from us, $8K from Tyler Cowen, $100K from the Thiel Fellowship, and raised $4.5M in 2022. When asked which was most meaningful, she pointed to the first $1K. It changed what she thought she was capable of. We still give out those grants.

Exceptional talent is widely distributed. Permission to use it is not. We started the Thiel Fellowship to find extraordinary young people and give them the freedom to pursue ambitious ideas. Fifteen years later, see what they’ve built.
From 2011 - 2014, the Thiel Fellowship gave out 40 $100k fellowships to entrepreneurs That were all under 20 years old at the time... 13 unicorns have since been built by those 40 fellows 4 of those 40 fellows are also now billionaires Absolutely insane hit rate

That's our girl @DStrachman and our boy Michael Gibson (@William_Blake), now doing the same work but at @1517fund

Thrilled to announce the general availability of @positron_ai's Atlas Inference Appliance on @OracleCloud, making Positron the first AI chip startup to be deployed at scale with a hyperscaler. Look out for more announcements this week at Oracle Cloud World! blogs.oracle.com/cloud-infra…

Claude has models named Haiku, Sonnet, and Opus. But does poetry actually have anything to teach people building technology? We asked a 2E camper. Her answer went from creativity to understanding other people, which might be the harder engineering problem.

April 2025: Michael Huynh was working out of a garage with blue tape on the floor, trying to get robots to work as a swarm. 18 months later: he's leading a team of 14, demoing drones they built from scratch for the U.S. military. We were Pheratech's first investors.

michael has spent years betting on young people. understanding what they’re saying is apparently a separate skill.

Record setting 1517 founders, now building a fusion reactor in SF!
Last month, we demonstrated high-rate alchemy: turning mercury into real, stable gold, beating CERN’s record by a factor of 10. Last week, we enriched isotopes in the world’s most powerful plasma centrifuge, beating the Soviet record that stood for 40 years. Now, we’re building a fusion reactor in San Francisco to achieve record power density.

Isaac Newton spent decades huffing mercury fumes in a Cambridge cellar, grinding lead into a worthless sludge while praying to the gods of alchemy. Now Marathon can use its reactor blanket to turn mercury-198 into stable gold by the ton. The alchemist will lose to the atom.

Spent 3 days last week with @DStrachman, @William_Blake & the @1517fund fam, including a day at her place. 1517 was @invariantes first fund investment in 2015. Exceptional returns, but they also helped shape me as an investor. Rare investors build companies & fellow GPs. Love ya!
Sixteen years ago, when @William_Blake and I were on the founding team of the Thiel Fellowship, we called it an older young person’s homeschool program. In a very Thiel-ian way, we built something that fostered independent thinking by giving young people permission to explore what interested them in an environment that trusted them to make decisions and execute on their work. @firstround’s editorial team wrote a really thoughtful piece about those first years of the fellowship. It also covers my journey — going from school founder to handing out $100K grants to teenagers. So wonderful to chronicle that very special time that has become the genesis of 1517 💗 (Link in comments)

We used a voting method borrowed from a fourth-grade classroom to help pick Thiel Fellows. Some of those fellows went on to build Ethereum, Figma, and Anthropic. The early days were a lot weirder than people remember review.firstround.com/inside…

Some scenes from 2E 2026. We got a bunch of unusually curious teenagers together, took them to see some wild technology, and let them spend a few days with people who are just as obsessed with their interests as they are. Pretty good way to spend a weekend.
