Retro Biosciences funding rounds
| Date | Stage | Investors | Raised | Valuation | Deal Summary |
|---|---|---|---|---|---|
| May 2026 | Undisclosed stage | 4P Capital (lead) | - | $1.8B | Retro Biosciences announced the initial close of its next financing round led by 4P Capital alongside other investors, at a **pre-money valuation of USD 1,800 million**. The company said the round was announced on May 22, 2026 and described it as an initial close of its next financing round, indicating the financing is not necessarily fully completed. The financing follows earlier reporting that Retro was seeking a much larger Series A-style raise, but the May 2026 announcement only confirms the initial close and valuation, not the full amount raised. The strategic rationale is tied to Retro’s aim of translating aging biology into a new generation of medicines, with investors backing the company’s lifespan-extension and therapeutics platform. Public reporting in early 2025 said Retro, backed by Sam Altman, was seeking $1 billion, and that Altman had previously funded its entire $180 million seed round. That context suggests continued investor confidence in Retro’s anti-aging drug development thesis and its position in the longevity biotech space. Retro Biosciences is a biotechnology company focused on aging and longevity therapeutics. Available funding references indicate it had raised USD 180 million across earlier rounds before this 2026 financing. No revenue or EBITDA figures were identified in the provided results. |
| Apr 2022 | Angel | Sam Altman (lead) | $180M | - | Retro Biosciences is a San Francisco-based biotech startup focused on extending human lifespan by 10 years through drugs targeting aging-related diseases like Alzheimer’s, using approaches such as epigenetic editing, cell replacement therapies, and AI-enhanced models trained with OpenAI to reprogram cells into stem cells. The company’s $180 million angel (seed) round occurred on April 5, 2022, entirely funded by OpenAI CEO Sam Altman, marking his initial investment in the longevity space. CEO Joe Betts-LaCroix has emphasized rapid drug development within the 2020s. The company has since pursued larger raises, including a $1 billion Series A in 2025 with Altman’s participation and a potential $1 billion round at $5 billion valuation reported in late 2025, positioning it among major billionaire-backed longevity efforts like Altos Labs ($3 billion launch in 2022). Traction includes plans for clinical trials and AI integration. Retro Biosciences operates in a competitive longevity market with strong Silicon Valley interest, boasting a team of PhDs in Redwood City, California. |
