The problem

Serious health data lives everywhere and nowhere

Today

A wearable on the wrist, bloodwork twice a year, the occasional epigenetic test, each trapped in its own app or PDF. No tool answers the question that matters: how fast am I aging, and is what I'm doing working?

  • Data scattered across apps that never talk to each other
  • Affluent optimizers already pay for depth, but no one serves them well
  • Blood-based rivals estimate age without the epigenetic clock

With Bio-Twin

One membership unifies everything, puts an epigenetic biological-age clock at the center, and coaches with cited evidence. It includes an annual TruAge kit mailed to you, with results flowing straight in.

  • All health, fitness & blood data in one place
  • Biological age + an 11-organ-system map
  • Evidence-backed actions, ranked by projected impact
  • Turns a one-time $499 test into a yearly membership
The product

A longevity command center people open daily

Already built as a working, interactive product, not a concept. Biological age leads, with organ ages, bloodwork, connected devices, and an AI coach around it.
