Longevity, rebuilt as software

Your blood already knows.
Now it texts you.

A finger-prick blood test at home, synced with your wearable and your plate. Every week, an AI coach reads all of it and sends you one text: what to change.

No clinic. No guru. No $15,000 membership.

Rejuveneer → you · Sun 8:00 AM Inflammation ticked up while sleep dropped below 7h. This week: lights out by 11, and swap the Thursday HIIT for zone 2. Everything else — keep doing exactly what you're doing.

The loop your body has been waiting for.

Three signals in. One decision out. Every single week.

01 / DRAW

Prick at home

An at-home blood kit arrives on your schedule. 50+ biomarkers from a finger prick — lipids, inflammation, metabolic, hormones — no lab visit, results via API straight into your profile.

Already have labs? Snap a photo of any Quest, Labcorp or hospital report — we scan it and it becomes structured history, instantly.

02 / SYNC

Wear & eat as usual

Your wearable streams sleep, HRV and activity. Log food by texting a photo or a sentence — we estimate the macros. No fifteenth app to open.

03 / TEXT

One text a week

The coach cross-reads blood, sleep, food and training — and texts you the single highest-leverage change for the next seven days. That's it. That's the product.

$15,000/yr

That's the concierge longevity clinic.
Rejuveneer runs the same loop for the price of a gym membership.

Bloodwork protocols, wearable review, nutrition audit, weekly adjustments — this is what the clinics actually do. We automated it.

RejuveneerScanned. 34 biomarkers from your 2024 physical added to your baseline — your trends now go back two years.
RejuveneerYour ApoB dropped 9 points since the March draw — the fiber change is working. Hold it. New focus: your deep sleep fell 22% the weeks you trained after 8pm.
so… morning workouts?
RejuveneerBefore 6pm is enough. Re-test in 6 weeks — kit ships automatically. Nothing else needs to change.

Not a dashboard. A decision.

Every health app gives you more charts. Rejuveneer gives you fewer: it reads everything and answers the only question that matters — "what should I do differently this week?"

It arrives as a text message. You can reply. It remembers your history, your draws, your last twelve weeks of sleep. Like a coach who never sleeps, minus the invoice.
