Whoop, which provides wearable fitness technology and a subscription platform that tracks physiological data for insights, announced Tuesday that it has raised $575 million in Series G funding at a $10.1 billion valuation.
The round marks a significant step-up in valuation from the $3.6 billion that Boston-based Whoop achieved in August 2021 when it raised a $200 million Series F round. In total, it has raised over $900 million since it was founded by Will Ahmed in 2012.
Collaborative Fund led its latest financing, which included participation from a slew of institutional investors, athletes and angels, including 2PointZero Group, Qatar Investment Authority, Mubadala Investment Co., Abbott and Mayo Clinic.
Individual investors in the round include soccer star Cristiano Ronaldo, NBA players LeBron James and Reggie Miller, and musician Niall Horan.
Whoop says it is powered by more than 24 billion hours of physiological data and purpose-built AI models to provide predictive, personalized health insights. It claims to help users understand how they slept, whether they have recovered, how hard to push or pull back, and how daily behaviors like training, nutrition and stress are impacting their performance and long-term health. It further ambitiously claims that it helps users “identify early warning signs, reduce risk, and take action that can prevent serious health events.”
Subscription-based insights
Its model is different from that of many wearables companies. The actual wearable doesn’t cost anything, but “members” pay a subscription to access the insights it offers. There are different tiers based on style and performance level.
Whoop has historically been more popular among athletes and die-hard workout enthusiasts, although it appears to be becoming more mainstream. The company says it now has over 2.5 million members globally, and that in 2025 bookings grew 103% year over year. It operated cash flow positive and ended the year at a $1.1 billion run rate.
The company is actively hiring for over 600 roles as it plans to double down on R&D and global expansion across Europe, the Middle East, Latin America and Asia.
Whoop’s round is a bright spot in a sector that hit a cyclical low last year after peaking about four years ago. Just over $5 billion in global venture funding went to fitness and wellness-related startups in 2025, Crunchbase data shows.
That said, it’s not as if investors have abandoned the space, and there are clearly still companies securing big rounds.
Last year, the standout was Oura, maker of a smart ring that collects data on dozens of personal health and wellness metrics. Last October, the 12-year-old Finnish company announced it had closed on more than $900 million in funding at an impressive $11 billion valuation.
