"If you die, all your crypto doesn't make sense. All your sustainability doesn't make sense. You have not solved the major existential issue or the major existential threat that you have."
In this episode of The Biotech Startups Podcast, host Jon Chee continues his conversation with Sergey Jakimov, Managing Partner at LongeVC, as he reveals launching a $25 million longevity fund. Leveraging relationships with top universities and a scientific advisory board featuring Nobel Prize winners, Sergey built a fund with an unconventional thesis: tackle age-related diseases one at a time, investing solely based on patient outcomes. The results—20 companies, zero write-offs in 3.5 years, with portfolio companies approaching unicorn status.
The conversation turns personal when Sergey shares his experience as a rare disease patient. At 28, a rare autoimmune neurodegenerative condition left him partially paralyzed, forcing him through a healthcare system offering only outdated treatments. This experience fundamentally reshaped his investment philosophy and cemented his belief that biotech is the most important industry. Sergey also discusses expanding his platform with Ani.vc and the Longevity Science Foundation, while reflecting on why health span and "joy span" matter more than simply extending lifespan.
Key topics covered:
- From Angel to Institution: Launching a $25M longevity fund with deal access, KOL relationships, and a science-first thesis
- Disease-by-Disease vs. Curing Aging: Why pragmatic, disease-focused investments outperform holistic longevity approaches
- A Founder's Health Crisis: How becoming a rare disease patient at 28 transformed Sergey's investment philosophy
- Exceptional Fund Performance: Achieving zero write-offs across 20 companies, with portfolio highlights in ADCs and cancer diagnostics
- Expanding the Platform: Building Ani.vc for animal health and the Longevity Science Foundation for fundamental research grants
