The company will be using the Series G raise to fuel further US growth and international expansion across Europe, the GCC, Latin America, and Asia.
Will Ahmed, founder and CEO of WHOOP, said: “Our raise brings together the world’s most sophisticated investors, leading health institutions, and iconic global athletes behind the mission to unlock human performance and healthspan.
“We are building the personal health platform that people use to improve their health and livelihood.”
WHOOP was founded in 2012 and is headquartered in Boston.
Powered by more than 24 billion hours of physiological data and purpose-built AI models, WHOOP delivers predictive, personalised health insights.
Members open the app an average of over eight times per day – almost three times higher than other screenless wearables – to understand how they slept, whether they are recovered, how hard to push or pull back, and how daily behaviours like training, nutrition, and stress are impacting their performance and long-term health.
The company has raised more than $900m in venture capital, ships to 56 countries, and operates in six languages.
In September 2021, GP Bullhound announced a new investment into WHOOP. The $200m financing round at a $3.4bn valuation was led by Softbank with participation from IVP and GP Bullhound Fund V.
The wearable tech giant now has over 2.5 million members around the world and in 2025, grew bookings by 103 per cent, exiting the year at a $1.1bn run rate.
The Series G round was led by Collaborative Fund and includes global participation from 2PointZero Group, Qatar Investment Authority (QIA), Mubadala Investment Company, Abbott, Mayo Clinic, Macquarie Capital (entities administered by Macquarie Capital), Glade Brook, B-Flexion, IVP, Foundry, Accomplice, Affinity Partners, and Bullhound Capital alongside a group of prominent global athletes and individual investors.
This funding comes at a time when chronic disease is rising globally and will enable the company to scale its platform as a new standard for personalised, preventive health.
In 2025, WHOOP was cash flow positive.
