personalized health for 8 billion people.

Traditional medicine optimizes for easy insurance process, not health outcomes. The wellness industry drowns you in generic, unsustainable routines. Both ignore the one variable that matters most — you.

37°N Labs is building deeply personalized experiences to end generic health. We map personalized protocols to first-principles cellular science: understanding exactly why an intervention works at the protein and cellular level.

From passive patient to active author of your own health.

Your body
isn’t an

The What02

Real science, matched to the outcomes that compound.

Our AI sifts basic science literature across thousands of randomized controlled trials. It throws out population averages and traces each result down to cellular mechanisms. It checks the mechanism against you: your genetics, your habits, your signals. What's left is the rare practice that should actually work for your biology, turned into outcomes that matter.

Genetics
The biology you were dealt.
Environment
Where and how you live.
Social
The people and rhythms around you.
Lifestyle
The choices you repeat each day.

The Open Lab04

Experiments,
in the open.

Single-purpose microapps, all built on the same engine. Easy to run, easy to share, straight about the evidence behind them. 22 in development · 64 in the backlog. Each one is a small experiment you run in a tap. The reason it works is always one tap away.

Tiny tools. One job each.
