RheoFit Secures Pre-A Funding to Revolutionize Recovery Tools

RheoFit, a Shenzhen-based consumer electronics company focused on musculoskeletal health, announced on October 24, 2025, the successful completion of its Pre-A funding round, led by Xiaohongshu (RED) and ZhenFund. This funding will propel the company’s mission to advance product development and expand its global footprint, enhancing the user experience with AI-driven healthcare and rehabilitation solutions.

Founded in 2023, RheoFit made headlines in September 2024 with the launch of the world’s first automatic foam roller, the RheoFit A1. The device aims to ease recovery after exercise, addressing a common concern among athletes. “We started RheoFit to solve a problem we all feel every day: why can’t recovery after exercise be easier and more effective?” said Adam Sun, CEO of RheoFit. Sun, a mechanical engineering graduate and marathon runner, recognized the limitations of traditional recovery tools during his own athletic experiences.

The development of the RheoFit A1 stemmed from a shared frustration among the company’s founders, who are both marathon runners and engineers. Traditional foam rollers often caused discomfort while massage guns sometimes led to numbness. This prompted them to innovate a solution that provides genuine relaxation without the effort typically associated with recovery tools.

The team dedicated over 1,000 days to refining their concept, resulting in the creation of more than 20 prototypes. Their perseverance paid off, as the RheoFit A1 quickly gained traction, reaching over 20 countries, including the United States, United Kingdom, Germany, Singapore, and Dubai. The product has become an essential recovery tool for athletes, whether at home, in gyms, or out on the trails.

Looking to the Future

With the backing from RED and ZhenFund, RheoFit is poised for significant growth. This funding round represents not just financial support but also a belief in the company’s vision. ZhenFund representatives noted, “We’re always looking for founders of tomorrow. The RheoFit team has a sharp understanding of market pain points and exceptional engineering execution.”

RheoFit’s philosophy aligns with a growing trend toward proactive, technology-driven health management, resonating with the community of users at RED. The company aims to foster a culture of wellness that combines scientific approaches with accessible technology.

As it embarks on this next chapter, RheoFit remains committed to its mission: to assist every runner in reaching their goals while recovering effectively. The journey ahead is not just about product development; it’s about transforming the recovery experience for athletes worldwide.
