Cyril Ebersweiler built HAX from a garage in Shenzhen into the world's first and largest hardware accelerator by basing himself directly inside Huaqiangbei so founders learn in the kitchen of the global supply chain rather than outsourcing manufacturing. He uses HAX's in-house engineering, design, and regulatory expertise as a moat to back atom-heavy companies that often look impossible to pull off, while pushing founders to think of robots as recurring revenue services through usage-based models like charging per square foot cleaned.

Notable Investments
HAX operates the world's first pre-seed program focused exclusively on hard tech startups building physical, science-based products in climate, industrial automation, and human health, with an in-house team of engineers, designers, and specialists who directly co-build prototypes and handle manufacturing design as an extension of founding teams. The program combines a 35,000 sq. ft. industrial lab in Newark with integrated teams in Shenzhen and Pune, giving founders simultaneous access to U.S. engineering capabilities and Asian manufacturing ecosystems while structuring investments as a mix of cash and in-kind engineering services to lower capital intensity for hardware development.
