How a founder fed his cancer data into AI—and won

Connor Christou, CEO of the Boston-based startup Sifted (which helps investors sift through deals), got cancer last year. He's known for pushing himself hard—run marathons, train hard, live disciplined. When the diagnosis came, he didn't just hand it off to doctors. He took his entire life into the data.

He fed everything into Claude: blood results, imaging, wearable output, even journal entries. The AI tracked his vitals, compared his numbers to medical literature, and flagged patterns his doctors might have missed. What came back surprised him. The model caught things he'd been missing—the kind of detail that shows up when you stop guessing and start measuring.

It's not magic. It's data. Christou is one of those founders who actually lives in the tools he builds, and he treated his own body like a product to optimize. The result? He used the model's output to make real decisions about treatment, and he's back to running marathons.

Why this matters for us: AI isn't just for tech founders and Wall Street anymore—when la gente learn to track their own health data, they get second opinions without paying for them.
