Altos Labs

Altos Labs is a longevity-focused biotechnology company founded in 2021 by billionaire entrepreneur Yuri Milner and others, with backing from major tech and biotech investors. The company focuses on cellular reprogramming technologies—reversing aging at the cellular level—drawing on research into induced pluripotent stem cells (iPSCs) and related rejuvenation approaches.

The company has assembled a team of prominent aging researchers and has established multiple research centers globally. Its scientific approach aims to develop therapies that could extend human healthspan by restoring cellular function and reversing age-related decline, rather than simply extending lifespan.

Altos Labs represents a significant bet by Silicon Valley on longevity science, combining academic research with venture-scale funding and commercialization ambitions. The company has raised substantial capital and operates with a long-term research horizon typical of fundamental biology efforts.
