Altos Labs, the $3B biotech startup backed by Jeff Bezos and other investors, is moving from research secrecy to clinical readiness. With Nobel laureates on board, new leadership, and breakthroughs in cellular reprogramming, Altos aims to extend human healthspan — shifting medicine from treating disease to preventing aging itself.
Altos Labs has emerged as one of the most ambitious biotech ventures of the decade. Founded in 2021, the company’s mission is to reverse aging at the cellular level using reprogramming technologies that reset cells to a youthful state. While initially secretive, Altos is now signaling readiness to move toward clinical trials, marking a new phase in its journey.
The company attracted global attention when reports revealed $3 billion in funding, with Jeff Bezos among its backers. Altos assembled a “dream team” of scientists, including Nobel laureate Shinya Yamanaka, whose discovery of induced pluripotent stem cells laid the foundation for cellular rejuvenation. By offering academic freedom and industry-level resources, Altos created an environment where cutting-edge science could thrive.
In 2025, Altos appointed Dr. Joan Mannick as Chief Medical Officer, a move widely interpreted as preparation for clinical translation. Mannick’s experience at Novartis, resTORbio, and Life Biosciences signals a shift from discovery to regulatory pathways. Meanwhile, scientific founder Juan Carlos Izpisúa Belmonte continues to lead research on “mesenchymal drift,” a process linked to aging and degenerative diseases.
Altos insists its focus is not immortality but extending healthspan ie the number of years people live free of disease. As President Hans Bishop explained, longevity gains are “an accidental consequence” of healthier living.
