About
WHOOP is a Boston-based wearable health and fitness technology company founded in 2012 by Will Ahmed with the mission of unlocking human performance through continuous physiological monitoring. Unlike traditional smartwatches that focus on notifications and step counting, WHOOP was designed from day one as a performance and recovery tool — worn 24/7, screenless, and focused entirely on the metrics that determine readiness: heart rate variability, sleep quality, respiratory rate, and strain. The company pioneered the subscription model for wearables, offering the hardware for free to members who pay a monthly fee for the data platform.\n\nWHOOP's wearable platform continuously monitors physiological signals and translates them into three daily scores — Strain, Recovery, and Sleep — that guide training and lifestyle decisions. The WHOOP 5.0 introduced medical-grade health monitoring capabilities including glucose trend tracking and expanded blood oxygen measurement. With 2.5 million or more members globally and $1.1 billion in annualized revenue, WHOOP has built one of the largest recurring-revenue bases in the wearables category. The platform is used by elite athletes, military operators, and health-conscious consumers across more than 100 countries.\n\nWHOOP raised $575 million in a Series G round in March 2026 at a $10.1 billion valuation, making it one of the most valuable private wearables companies in the world. The round was framed as a pre-IPO financing, with an initial public offering anticipated as the company's next major milestone. WHOOP competes with Apple Watch, Garmin, and Oura Ring but differentiates through its subscription-first model, medical-grade biometric depth, and elite performance positioning. Its $10 billion-plus valuation reflects investor confidence in the convergence of wearables, health AI, and the growing consumer longevity movement.
