Michael Polansky is training an AI model on skin that’s still alive
Why it matters
This represents a novel application of AI training on biological systems (living skin tissue as a data source for compound discovery), which is a frontier capability play in biotech AI. The ability to train models on live tissue rather than static datasets or animal models is a methodological breakthrough that practitioners in biotech and AI need to understand.
Key signals
- Michael Polansky (Lady Gaga's partner, former Sean Parker deputy) founded the startup
- Company keeps living human skin tissue alive for weeks outside the body
- AI trained on live tissue to discover new skincare compounds
- Stealth phase lasted years before public disclosure in August 2026
- Novel training data source: living biological tissue vs. traditional static datasets
- Michael Polansky (Sean Parker's former deputy, Lady Gaga's partner) leading the startup
- AI model trained on living human skin tissue kept viable ex-vivo for weeks
- Goal: discover new skincare compounds via AI-driven biological screening
- Stealth operation for years; public announcement only recent
- Novel training data source: biological substrate vs. traditional datasets
The hook
Not a celebrity vanity project. Michael Polansky is training AI on living human tissue to discover skincare compounds — a novel data source that could reshape how biotech validates molecules before human trials.
Michael Polansky — better known publicly as Lady Gaga's partner and a former top deputy to Sean Parker — has quietly spent years building an AI-driven startup that keeps living human skin tissue alive for weeks outside the body to discover new skincare compounds, and is only now going public about i…
