DELIAN ASPAROUHOV

Joined Founders Fund as a principal in his early twenties, making him one of the youngest partners at a major venture fund. Co-founded Varda Space Industries in 2020 — a company that manufactures products (particularly pharmaceuticals) in microgravity.

Varda successfully launched its first space factory capsule in 2023 and returned it to Earth with manufactured materials — a historic first. Varda has raised over $100 million in venture funding.

At Founders Fund, has been involved in investments across defense tech, space, and frontier technology. Worked previously at Peter Thiel's other ventures.

Vocal advocate for American defense technology innovation. Active on X (Twitter) where he shares strong opinions on tech, defense, and government.

Frontier technology investing. Asparouhov bets on technologies that most VCs consider too hard, too risky, or too weird: space manufacturing, defense tech, and deep science.

His Founders Fund role gives him access to the most ambitious founders in Silicon Valley. His investing thesis aligns with Peter Thiel's "definite optimism" — the belief that specific, ambitious technology bets can reshape the world.

Varda Space Industries' successful first mission — sending a capsule to orbit, manufacturing in microgravity, and returning to Earth — proved that space manufacturing is technically feasible. This is a historic achievement.

If Varda can scale, the applications for pharmaceuticals alone could be worth tens of billions. The early Founders Fund investments have also been strong.

Too early to judge fully. Varda is pre-revenue and requires enormous capital to scale.

Space manufacturing is technically proven but commercially unproven. If manufacturing costs don't come down dramatically, the business model won't work.

The risk is that Varda proves the science but can't prove the economics.

Build things that seem impossible until they're not. Asparouhov explicitly follows the Thielian philosophy that contrarian bets on hard technology are the highest-return investments.

"If something sounds crazy but the physics works, it's probably going to happen — the question is when and who builds it."

Bulgarian heritage — his last name reflects his Bulgarian roots. Keeps personal life mostly private.

Known primarily through his professional work at Founders Fund and Varda.

MIT (attended). Bulgarian-American background.

His technical education gives him the ability to evaluate deep-tech companies at a level most VCs cannot.
