The investor list tells you exactly what WHOOP is now.

$10.1 billion for a company that gives away a screenless rubber band. The device has no screen. No buttons. No display. The hardware is free with every subscription. WHOOP charges $199 to $359 per year for the right to look at your own biometric data in an app.

2.5 million members. $1.1 billion bookings run rate. 103% year-over-year growth. Cash flow positive. Those are SaaS metrics from a company that started as a wristband for CrossFit athletes.

Now look at who wrote checks. Qatar Investment Authority. Mubadala. Abbott. Mayo Clinic. Sovereign wealth funds and two of the largest healthcare institutions on Earth. QIA manages over $500 billion. Mubadala manages $300 billion+. These are the same funds buying stakes in global hospital networks, pharmaceutical pipelines, and biotech platforms. They did not invest $575 million because they think recovery scores are cool.

WHOOP sits on 24 billion hours of continuous physiological data. Heart rate variability, respiratory rate, skin temperature, SpO2, sleep architecture, blood pressure, ECG, and now blood biomarkers through Advanced Labs. From 2.5 million people wearing the device 24/7, generating data every single second.

Abbott makes glucose monitors, diagnostics equipment, and cardiac devices used in hospitals worldwide. Mayo Clinic runs one of the largest clinical research operations in medicine. When both of them invest in the same wearable company in the same round, they're buying a distribution channel for continuous patient monitoring outside the clinic.

The athlete investors are the packaging. Ronaldo, LeBron, Rory McIlroy, Virgil van Dijk. Their names make the fundraise go viral. Their actual function is keeping WHOOP positioned as a performance brand while the cap table quietly fills with healthcare infrastructure capital.

Previous valuation: $3.6 billion in 2021. Today: $10.1 billion. A 2.8x jump in five years, with the entire delta coming after WHOOP got FDA clearance for ECG and blood pressure monitoring. The regulatory moat is the valuation inflection.

Will Ahmed built a fitness tracker. The cap table says he's building the consumer front-end for the next generation of preventive medicine. The $10.1 billion bet is that the hospital of the future starts on your wrist.

this was a surprise…I appreciate you Reggie! Does everyone just wear whoop now

Perfectly put. AI is the fabric and infrastructure, not the product.

I’ve long thought that coding would become abstracted away and commoditized over time, and that deciding what to build would be the thing versus the actual act of building. Surreal to see it actively happening

Members share things with WHOOP every day — how rested they feel, how a workout felt, when travel threw off their routine, when an injury slowed them down, or when they hit a new life challenge. Together, they tell the real story of your year.

This year, WHOOP AI connected those everyday moments with your physiological data to power a more complete Year in Review.

In April, a member shared that constant work travel was draining their energy. WHOOP connected that reflection with their lowest Recovery of the year — showing how disrupted sleep and stress shaped their performance.

In July, they mentioned rolling an ankle on a hike. WHOOP saw how their activity shifted and how their Sleep Performance improved as they focused on rest and recovery.

By October, they celebrated running their first half-marathon. WHOOP identified that day as their peak Strain of the year — turning a single check-in into a meaningful highlight of their Year in Review.

These daily conversations with WHOOP become the context that turn raw metrics into something meaningful, into the story of your life.

Your Year in Review isn’t just a recap of numbers. It’s a reflection of the moments you shared, the challenges you navigated, and the goals you grew into over time.

And as WHOOP AI continues to learn from your world — your routines, your comments, your questions, your wins — next year’s review will capture an even fuller picture of your journey.

Keep sharing the moments that matter. WHOOP will connect the dots.

Japan was eliminated from the World Cup today in a game where they were leading 2-0. Despite their heartbreak they took the time to clean their bench and locker room leaving it perfectly clean. Thank you for being an example of pure class and I hope more take your lead.
