Join three Harvard founders building technology that doesn't exist yet; shape the future of human performance

Wear our prototype 24/7; help us prove that continuous monitoring unlocks athletic potential

Lead our seed round; fund a team solving a problem that matters to the world's best athletes

Recovery and sleep are more important than exercise tracking; current wearables miss what actually matters

Your body holds secrets you can't feel; HRV and continuous data reveal when to push and when to rest

Elite athletes will validate the product; their adoption creates an unassailable brand halo for consumers

Build something that helps athletes avoid the overtraining, injury, and burnout you've felt yourself

Stop guessing why you plateau, collapse, or get injured; finally understand your own physiology

First-mover advantage in recovery science; capture the high-value segment giants like Nike are ignoring

You're a talented engineer or data scientist at Harvard. You want to build something that matters.

You're an elite athlete. You train 3-4 hours daily. You have no idea what that means for your body.

Wearables are exploding: Nike FuelBand, Fitbit, Jawbone. Everyone is chasing steps.

Big tech companies and legacy brands are building fitness gadgets, but none understand physiology.

You overtrain, plateau, collapse. 70% of athletes experience this. Current trackers count steps, not recovery.

Most wearables have sky-high churn; users abandon them in months. Hardware alone isn't defensible.

Three Harvard students found what 500 medical papers revealed: HRV and continuous data unlock recovery.

A 24/7 wrist sensor measures what you can't feel: recovery, strain, sleep stages. Your body's secrets revealed.

Elite athlete validation builds brand equity that scales to consumers; subscription data creates stickiness.

Early prototypes working with Cambridge Consultants; custom ML algorithms solving unsolved problems in PPG.

LeBron James and Michael Phelps among first 100 users; their trainers integrate WHOOP into regimens.

$3.39M seed (Aug 2013) from Atlas, Founder Collective, NextView, Accomplice; Board includes MIT Media Lab founder.

Own founding equity in technology that could change how humans understand performance forever.

Feel what it's like to truly know your body; join the athletes who never want to take this off.

Back a contrarian bet: recovery over activity, data over hardware, elite adoption before mass market.

Join a 500+ person team building the most valuable standalone wearables company; own equity in a $3.6B business

Start your free trial today; discover what elite athletes already know about their bodies

Lead our next growth stage; invest in a proven $3.6B platform with 200K+ subscribers and low churn

WHOOP attracts world-class talent solving hard problems at the intersection of hardware, software, and human physiology

Recovery and sleep matter more than exercise tracking; your body holds secrets only continuous data can reveal

Subscription wearables beat one-time hardware sales; elite athlete credibility creates a defensible moat

Work on technology used by LeBron, Phelps, and Navy SEALs; your skills shape how humanity understands performance

Stop guessing why you feel tired, plateau, or get injured; know exactly when to push and when to rest

Capture the premium segment of a $192B wearables market with a sticky, recurring revenue model

You're a talented engineer, designer, or data scientist. You want your work to matter beyond metrics.

You train hard. You sleep poorly. You plateau, get injured, or burn out without knowing why.

Wearables crashed after Jawbone; investors are cautious about hardware without recurring revenue.

Big tech pays well but your impact disappears into products used mindlessly. You crave meaningful work.

Fitness trackers count steps but can't tell you if you should push harder or rest today.

One-time hardware sales create boom-bust cycles; most wearable companies flame out quickly.

WHOOP inverted wearables: recovery over activity, insight over notifications. Built from 500 medical papers.

WHOOP measures 100x per second, synthesizing strain, recovery, and sleep into actionable coaching.

Subscription model with free hardware creates predictable revenue and remarkably low churn rates.

500+ employees, Boston HQ in Kenmore Square; alumni have shaped the future of health wearables.

Used by elite athletes, Fortune 500 CEOs, and everyday performers; members report fewer injuries, better sleep.

$3.6B valuation, $406M raised; NFLPA, PGA, MLB partnerships; expanding into healthcare and B2B.
