All-In PodcastWHOOP CEO, Will Ahmed: 50B Hours of Health Data, a 4 Million Member Data Moat, & the FDA Fight
All-In Podcast
Whoop’s growth and model 0:00
Whoop says the average member wears the device 23.6 hours a day, and the company has collected more than 50 billion hours of continuous physiological data. It has grown to just over 4 million members. Will Ahmed explains that the business shifted from a one-time $500 device sale to a subscription model of about $15 to $30 a month. That lower entry price helped growth, and the subscription focus pushed the company to care more about retention, engagement, and improving the member experience over time.
Core metrics and alerts 8:00
Whoop’s main pillars are sleep, recovery, and strain. It tracks sleep quality, consistency, REM and slow-wave sleep, plus a recovery score that runs from red to green. Ahmed says the journal feature matters because the more you log, the more useful the product becomes. He also describes the health monitor, which watches respiratory rate, resting heart rate, skin temperature, blood oxygen, and HRV. He says those signals have warned him before symptoms appeared, including chest pain tied to lung inflammation and an earlier Covid case.
Heart rate variability 15:31
Heart rate variability sits at the center of Whoop’s stress and recovery scores. It is measured all day, compared against your own baseline, and tracked over time so you can see whether you are getting healthier or less healthy. Ahmed says the company was built around 24/7 data and a 14-day battery so you do not need to take it off, even for showers, baths, or sleep.
Data and coaching 19:30
With members wearing Whoop almost all day, the company now has more than 50 billion hours of continuous physiological data. It is using that data, plus blood tests, medical records, and journal entries, to train its own models and build an AI coach. The journal tracks habits like alcohol, travel, meditation, mood, and late meals, and those logs feed behavioral insights on recovery.
Tracking skiing and goals 30:31
He uses Whoop with meditation apps, but admits he still forgets to log some sessions. Skiing is tracked through Slopes, and that data feeds into his activity record. The system now builds a training plan around his goals. He says he wants to avoid injury and ski better, so the AI suggests exercises and uses long walks, rucking, and farmers walks as part of the plan.
GLP tracking and FDA 32:30
He also tracks a GLP-1, saying he lost 43 pounds and wishes he had Whoop during that stretch. The GLP tracker pushes steps, strength work, hydration, and protein, since weight loss can also mean muscle loss. He then turns to the FDA, saying blood pressure insights were challenged, but Whoop kept pushing. The company still offers blood pressure and ECG features, and he says it does not sell data.
Recovery Over Cardio 45:30
Will says most people should lift more weights and spend less time on an elliptical if they have an hour to exercise. Muscle mass matters for longevity. He then answers quick choices on Whoop habits. On vacation, he would use recovery or sleep to guide wake-up time, but if you are running a tech company, he says you should set an exact alarm. He drinks coffee right away. Of Whoop’s three scores, he watches recovery most closely and waits each morning for the color of that dial.
