Huge congrats to Will Ahmed and the entire Whoop team on their new $575M Series G funding round.
What is the value of a business whose sole mission is to help every member become healthier each day, and that holds a gold mine of data that is literally saving lives? The team has countless personal stories of how Whoop has saved lives by alerting members to key metrics that are out of range, often with no noticeable health conditions or symptoms.
Research shows people who wear Whoop log more than 90 additional minutes of exercise per week, get over two extra hours of sleep, and have 10% higher heart rate variability. That is quite a compelling value proposition, and it shows why so many people continue to join the Whoop platform to improve their health.
Here are some more remarkable stats from Whoop:

Whoop's new round was led by our friends at Collaborative Fund and includes participation from Qatar Investment Authority (QIA), Mubadala Investment Company, 2PointZero, Abbott, Mayo Clinic, Macquarie Capital, IVP, Foundry, Accomplice, and others. Individual investors in the round include Cristiano Ronaldo, LeBron James, Rory McIlroy, Shane Lowry, Niall Horan, Karen Wazen, Virgil van Dijk, Mathieu van der Poel, and others.
It's easy to invest in a team that builds a continuous health monitoring product so central to my life that I cannot imagine a day without checking my Whoop stats. Promus Ventures is excited to have invested again in this Series G and privileged to have been one of Whoop's seed investors many years ago. If you want more backstory, we've written about Whoop along the way here and here.
The greatest sales channel of any product is its customers. Over the many years I have worn Whoop on my wrist, I've been asked countless questions about it by people all over the world. I'm sure this happens to many Whoop members. I often find myself next to a stranger, scrolling through the Whoop app and showing the myriad of data and insights it provides each day. It's a strangely bonding experience with people I've never met - because we all care about our health and want to better understand our bodies.

Often in these posts from venture capital people, the whole point of the writing is to make you understand just how important said VC is to the company that just raised capital. It's really not to highlight the company or the team or the round, rather humble brags up and down making sure the world knows that the firm is a key reason for their success.
We'll state for the record that the Whoop team deserves all the accolades. Over the many years we've worked alongside Will and the exceptional Whoop team, it has been a joy to watch their journey and success. Stay in the boat. Never stop rowing. Keep trying new things. Be methodical about quality. Deliver an extraordinary experience. Continue providing value with each iteration. Nothing great comes without sacrifice, and the Whoop team has kept chugging through the tough moments every startup faces along the way.
So we're beyond stoked to see their great success. Whoop has built an extraordinary platform and is now one of the leading personal health brands in the world. And the world is better (and healthier) for it.
