Sweat-sensing wearable innovator, Epicore Biosystems has announced an additional US$6 million in Series B funding, bringing the total raise to US$32 million.
Following an initial US$26 million Series B raise, led by the Steele Foundation for Hope, this fresh investment positions the company to accelerate its global expansion and scale next-generation sweat-sensing technologies.
Epicore wearables measure sweat composition, fluid losses and physiological markers – such as skin temperature, motion and thermal flux – to give real-time feedback on early signs of fatigue and heat exhaustion and to inform hydration. The wearables have been piloted at major professional sports events, such as the 2025 Super Bowl and are used by the US Army and Navy.
The product range includes the Gx Sweat Patch used for the hydration and wellness of athletes; the Discovery Patch Sweat Collection System which is FDA registered for clinical trials and the Connected Hydration wearable and cloud platform tailored for industrial workers, which delivers real-time haptic alerts to guide personalised hydration routines.
The company says these solutions provide measurements and continuous monitoring capabilities that address the full spectrum of needs for physically demanding occupations and wellness applications.
Key growth initiatives with the fresh capital are to expand Connected Hydration into Australia, the Middle East and Asia; scale real-time cloud analytics with personalised hydration guidance and recommendations and validate novel biomarkers for applications in kidney health and stress management.
Dr Roozbeh Ghaffari, CEO and co-founder of Epicore Biosystems, says: "We're thrilled to have mission-driven investors onboard who recognise both the value of new data streams and the utility of biosensor technologies to transform safety, well-being and productivity."
Michael Edelhart, managing director of Joyance Partners, says: "We are proud to support the team's efforts to fundamentally transform the way we approach hydration health, wellness and performance at a global scale."
Epicore spun out of Northwestern University's Querrey Simpson Institute for Bioelectronics and the John Rogers Laboratory. The new investment comes from a San Francisco-based investor and marquee angel investors, along with continued support from Alumni Ventures and Joyance Partners.
