A Trillion-Dollar Blindspot
Your AI agent will schedule your hardest meeting when your nervous system is depleted. It will push you through a 14-hour day when your biology is screaming for recovery. It optimizes what you do — without understanding who you are.
Are Already Burning Out
Most knowledge workers are running on fumes. The AI tools they rely on have no idea.
Of YC is Building Agents
The agent revolution is here — but every single one of them is blind to your biology.

Two Realities. One You.
There's the version of you on your calendar — and the version your body is actually living. No tool today catches that gap.
Your Calendar Says
- 12 Hours of Deep Work
- On Track for Launch
- Three Calls, No Conflicts
Your Body Says
- Heart Rate Variability Crashed
- Running on 4 Hours of Sleep Debt
- Stress Response Still Firing
What Actually Happens
- You Ship the Wrong Decision
- The Burnout Hits Next Tuesday
- Nobody Saw It Coming — Except Your Watch
Your calendar is a performance. Your body is the truth.

Every Agent Will Need a Body
We're looking for investors who see it, early adopters who feel it, and partners who want to build the future of personal AI — starting from the inside out.
