Rise Science
Series ABetter sleep, better energy
A sleep and energy tracking app that uses sleep debt science and circadian rhythm analysis to help users optimize their daily energy and performance.
About
Rise Science built the RISE app around the two principles that sleep researchers agree unlock better days: sleep debt and circadian rhythm. The app calculates your personal sleep need, tracks how much sleep debt you carry, and predicts your daily energy schedule โ all without requiring a wearable. Founded by Jeff Kahn and Leon Sasson after apprenticing in sleep study, RISE has been adopted by elite athletes (contributing to two Super Bowl wins), Fortune 500 companies, and over a million individual users. The company reports 80% of users feel benefits within five days of using the app.
DailyDropout Take
Rise Science stood out for its science-first approach to sleep โ focusing on the two factors that actually matter (sleep debt and circadian rhythm) rather than gamifying sleep scores. Their B2B traction with NFL teams and Fortune 500 companies validated the product before the consumer launch.
Discovery signal: Strong B2B traction with professional sports teams and enterprise clients before consumer app launch
What Makes Them Unique
RISE focuses uniquely on sleep debt and circadian rhythm rather than sleep stages or sleep quality scores. It works without a wearable device and predicts energy levels throughout the day, helping users optimize when to do focused work, exercise, and wind down.
