Company Overview

About Retro Biosciences

Retro Biosciences is the largest-funded pure-play longevity company in history, raising $1 billion in Series A financing at a $5 billion valuation with Sam Altman (OpenAI CEO) as a primary backer. The company is pursuing cellular reprogramming, autophagy enhancement, and plasma factor therapeutics in parallel — a multi-pronged approach to extending healthy human lifespan by targeting the cellular hallmarks of aging simultaneously.

Business Model & Competitive Advantage

The $5B valuation with zero clinical data reflects extraordinary conviction from tech-founder capital that biological aging is fundamentally a solvable engineering problem. Retro is preparing its first human trial, targeted to launch in Australia, which will be a pivotal test of the cellular reprogramming hypothesis in vivo. The company works with leading academic researchers in aging biology and benefits from Sam Altman's network for scientific talent recruitment.

Competitive Landscape 2025–2026

Retro's approach is distinctively ambitious: rather than targeting a single disease or aging pathway, it is attempting to reverse the fundamental epigenetic aging clock that drives age-related decline across all tissues. If successful, this would represent a paradigm shift from disease treatment to genuine biological rejuvenation — a category of medicine that does not yet have an approved product anywhere in the world.
