Boston-headquartered fitness wearable startup Whoop has successfully closed a $575 million Series G financing round. This latest capital injection pushes the company’s valuation to $10.1 billion, marking a significant jump from its $3.6 billion valuation following its 2021 fundraising effort.
Collaborative Fund spearheaded the investment round. Additional participants included Qatar Investment Authority, Mubadala Investment Company, Abbott Laboratories, Mayo Clinic, Macquarie Capital, and GP Bullhound.
A roster of world-renowned athletes joined the funding round as individual backers. Cristiano Ronaldo, LeBron James, Rory McIlroy, Reggie Miller, Niall Horan, and Virgil van Dijk all contributed capital to the raise.
Will Ahmed established Whoop in 2012. The company manufactures a display-free fitness tracker that continuously monitors recovery metrics, sleep patterns, and physical exertion levels throughout the day.
Unlike conventional smartwatches, the device doesn’t display notifications or provide smartphone connectivity. This approach differentiates it from competitors like the Apple Watch, which merges fitness monitoring with comprehensive smart device functionality.
Whoop operates on a membership-based business model. The wearable band is included with subscription plans, currently priced at $239 annually as of early 2026.
Impressive Revenue Momentum
The company documented 103% year-over-year expansion in bookings. By the end of 2025, Whoop achieved a $1.1 billion bookings run rate while maintaining positive operating cash flow.
Whoop’s user community has grown to 2.5 million members. The firm has accumulated more than $950 million in total financing since inception.
Product Innovation and Healthcare Capabilities
Whoop unveiled its latest Whoop 5.0 device alongside a specialized variant called Whoop MG. The MG model obtained FDA authorization for clinical-grade ECG monitoring and blood pressure measurement capabilities.
The company’s ecosystem incorporates an artificial intelligence feature known as Whoop Coach, delivering customized workout recommendations based on individual user metrics.
Oura Health, creator of the Oura Ring, represents Whoop’s primary competitor in the health wearables sector. Oura secured funding last autumn that elevated its market value to $11 billion.
Whoop’s current workforce stands at approximately 800 full-time employees. The organization intends to grow its team by as much as 75%, adding more than 600 positions spanning software engineering, hardware development, sales operations, and marketing functions.
This aggressive expansion strategy has fueled speculation regarding a possible initial public offering. Company representatives have not publicly addressed any plans for going public.
With its present $10.1 billion valuation, Whoop ranks slightly beneath Shield AI at $10.4 billion and Kraken at $10.5 billion among the highest-valued privately held companies, based on Yahoo Finance reporting.
