Listen to your biology

Your body knows
more than your
watch.

Sunesis reads your blood markers alongside your training data to give you a daily prescription — what to eat, and whether your body is truly ready. Not what the algorithm thinks. What your biology is actually saying.

You're on the list. We'll be in touch.

No spam. Early access only. For athletes ready to go deeper than the dashboard.

Beyond the dashboard

Devices track effort. Blood reveals recovery.

Sunesis brings both together so your prescription is grounded in biology, not just activity. Your markers don't estimate — they evidence.

Readiness you can trust

Your HRV score is an estimate. Your blood is evidence.

Ferritin, cortisol, inflammation markers — Sunesis builds your readiness signal from what your body is actually producing, not what a sensor infers.

Intuition, validated

That feeling that something's off? Your blood usually knew first.

Sunesis helps you connect the signal your body was already sending to the action you should take — with a plain-English reason for everything.

How it works
01

Connect your training data

Sync Garmin, Wahoo, or Whoop in seconds. Sunesis uses your training load, HRV, and sleep as context — not conclusions.

02

Upload your blood panel

Forward a PDF from your last lab results. Our AI parses the markers that actually matter — the honest signals your device can't measure.

03

Receive your daily prescription

Each morning: what to eat, how much, and a true readiness signal for your training. Every recommendation explained in plain language — no black-box scores.

04

Your body, understood over time

As your blood markers evolve, your prescriptions adapt. Sunesis builds a picture of your biology — not just a log of your sessions.

Why your body needs more today: Your ferritin is trending low — a signal your device can't see. With a threshold run scheduled, we've increased carbs and flagged iron-rich foods at dinner. Your body was already telling you something was off.
