Overview
Retro Biosciences is a longevity biotech startup backed by OpenAI CEO Sam Altman (a $180 million seed investment) developing therapies aimed at extending human healthspan, including a clinical-stage pill designed to enhance the body's ability to clear protein aggregates in Alzheimer's disease patients. The company reached a $1.8 billion valuation as of May 2026 after raising additional capital beyond its initial $1 billion Series A target of a $5 billion valuation, following a Q1 2025 $1 billion round that was, at the time, the largest single longevity-biotech funding deal on record.
Strategic Connections
- OpenAI: OpenAI CEO Sam Altman provided Retro Biosciences' initial $180 million seed investment.
- Gene Editing & Longevity Biotech: Retro Biosciences develops longevity and healthspan-extension therapies, including a clinical-stage Alzheimer's treatment, as part of the broader longevity biotech investment wave.
- Altos Labs: Retro Biosciences competes with Altos Labs in the longevity biotech investment space, both backed by prominent tech figures betting on healthspan-extension research.
Strategic Risks
- Longevity biotech as a category has produced limited clinical validation to date, creating substantial scientific and regulatory risk despite large capital inflows
- Heavy reliance on a single prominent backer (Sam Altman) for credibility and capital concentrates reputational risk
Future Outlook
- Clinical trial results for its Alzheimer's protein-aggregate clearance therapy will be a key near-term validation point
- Continued large capital inflows into longevity biotech as prominent tech investors compete for stakes in the category
