Altos Labs is a biotechnology company pursuing cellular rejuvenation programming to restore cell health and resilience, with the goal of reversing disease, injury, and the disabilities that can occur throughout life. Launched publicly in January 2022 with roughly $3 billion in initial funding from investors including Jeff Bezos and Yuri Milner, the company operates geographically distributed Institutes of Science in the San Francisco Bay Area, Cambridge (UK), and San Diego, alongside an Institute of Medicine and an Institute of Computation. Altos combines experimental biologists with computational scientists to translate laboratory discoveries in cell biology into transformative medicines. It was surfaced as a portfolio company of General Catalyst and added to the API Evangelist network; as a research-stage life-sciences company it currently exposes no public developer API surface.
