Whoop
Whoop is a Smart Rings & Recovery company founded in 2012 and based in Boston, United States. It has raised $976.4M in total funding, most recently a Series G in 2026 at a $10.1B valuation.
Founded in Boston in 2012, Whoop pairs a screenless wristband with a subscription service that tracks strain, recovery, and sleep, aimed at athletes and high-performance professionals. It has launched WHOOP 5.0 and the medical-grade WHOOP MG (ECG and blood-pressure sensing) and added a generative-AI Whoop Coach. The company raised a $575M Series G in March 2026 at a $10.1B valuation, with roughly $1.1B in 2025 bookings run-rate, and has signaled the round may be its last before an IPO.
Whoop pioneered the subscription-hardware model in wearables and established strain and recovery as a monitoring paradigm distinct from step-counting; its Whoop Coach feature signals the integration of LLMs into personal health analytics.
