About the Company

Whoop

Makes screenless trackers for sleep and recovery

Whoop makes a screenless wristband that tracks sleep, exercise strain, and recovery around the clock, and it sells the band to athletes and everyday users only as part of a membership. In 2020, the PGA Tour gave Whoop straps to players and caddies after one golfer's data flagged his COVID-19 infection before he had symptoms. The band records heart rate, the variation between beats, skin temperature, and blood oxygen, and the app turns those readings into daily scores and advice on when to push or rest. Members pay a yearly fee that covers the band, with pricier tiers adding heart-rhythm and blood pressure readings, and Whoop also sells blood tests. Whoop was founded in 2012 at Harvard's startup lab and is based in Boston.
