Boston-based wearable company Whoop has raised $575 million in new funding, boosting its valuation to over $10 billion, roughly three times what it was four years ago, the company said.

The company, which tracks biometric data to optimize performance and recovery, has more than 2.5 million members and grew bookings by 103% year-over-year.

It ended 2025 with a bookings run rate of $1.1 billion and was operating cash flow positive, according to Bloomberg.

Founder and CEO Will Ahmed said the new capital will fuel an “ambitious research and development road map” that could eventually enable the company to predict heart attacks and strokes. “This round brings together an extraordinary group of investors that reflects both where we’ve come from and where we’re going,” Ahmed said.

The funding was led by Collaborative Fund and included participation from 2PointZero Group, Qatar Investment Authority, Mubadala, Abbott, Mayo Clinic, Macquarie Group, Glade Brook Capital Partners, B-FLEXION, IVP, Foundry, Accomplice, Affinity Partners, Promus Ventures, and Bullhound Capital.

The round also attracted high-profile individual investors, including soccer star Cristiano Ronaldo, NBA player LeBron James, golfers Rory McIlroy and Mathieu van der Poel, and soccer defender Virgil van Dijk.

Ahmed said the investment reflects Whoop’s expansion from a performance-focused wearable trusted by elite athletes to a broader preventive health platform. “Healthcare systems around the world are reactive,” he said. “At Whoop, we believe the future looks fundamentally different. We are building the most powerful, personal, preventive health platform in the world — powered by continuous biometric data, advanced analytics, and AI.”

Over the past year, Whoop has received medical clearances, launched blood testing, and created a platform the company says has already saved lives. Abbott and Mayo Clinic’s participation as investors signals a step toward integrating Whoop technology with mainstream healthcare, Ahmed said.

Whoop is expected to file for an initial public offering in the near future, though the company has not disclosed a specific timeline.
