The fittest founder in the room got cancer. Here’s how he used AI to fight back.

Conno Christou doesn’t leave things to chance.

The short version

• He tracks his sleep with a Whoop band, cross-references it with an Oura ring, and gets nearly 100 biomarkers checked every year.
• He had been doing the annual bloodwork for four consecutive years, following the protocols of longevity researchers like Peter Attia and Rhonda Patrick.
• He was optimizing his supplements, his circadian rhythm, his protein intake.
• At 35, building his second company, he was as dialed-in on the latest in health research as anyone he knew.

What happened

His last checkup, in 2025, was green across the board. A week passed before he saw a doctor, who found two blood clots in his veins and scheduled surgery.

Why it matters

A doctor walked back into the room and told him the procedure wasn’t happening.
