Fourier

Fourier (傅利叶, also known internationally as Fourier Intelligence) is a Chinese robotics company headquartered in Shanghai. It was founded in 2015 by Zen Koh and has become one of China's better-known developers of rehabilitation robotics and, more recently, general-purpose humanoid robots. The company's official website presents its mission as "以机器人科技赋能生活" — using robotics technology to empower life — and brands itself simply as "傅利叶 · Fourier." Fourier's early commercial identity was built around rehabilitation and medical robotics. Its product families include exoskeleton-style gait training robots, upper-limb rehabilitation robots, and related therapy platforms used by hospitals, rehabilitation centers, and clinics. These products combine robotic hardware with software that supports therapists and patients through repetitive, measurable training programs. This focus gave the company a clinical and healthcare-oriented reputation rather than a purely consumer-electronics one. More recently, Fourier has become widely associated with the humanoid robot wave in China. The company has developed general-purpose humanoid robot platforms intended for research, embodied-AI development, and eventual service applications. This has placed Fourier alongside other Chinese humanoid robotics startups in the global conversation about general-purpose robots, and it has helped the brand move from a niche rehabilitation-robotics supplier toward a broader robotics platform company. The company operates primarily from China and sells into international markets, with overseas offices and distribution relationships supporting its rehabilitation and research robotics business. Its website, fftai.com, serves as the main brand and product gateway, carrying the tagline "傅利叶 · Fourier · 以机器人科技赋能生活." Because Fourier is a private company, detailed financial figures are not consistently public. Its brand equity rests on its dual identity: a clinically grounded rehabilitation robotics maker and an emerging humanoid robotics platform developer. For a brand knowledge base, Fourier should be classified as a robotics and technology company, not as a food or consumer-staples brand, despite any taxonomy hints that may have been attached to the name.

Fourier was founded in 2015 in Shanghai as a robotics company focused on rehabilitation and medical robotics. Its early work centered on robotic systems that could assist patients recovering from stroke, spinal cord injury, and other conditions requiring repetitive movement therapy. Products such as gait training exoskeletons and upper-limb rehabilitation robots were developed for hospitals, rehabilitation centers, and clinics, combining robotic hardware with software that tracked and supported therapy sessions. Over the following years, Fourier expanded its rehabilitation robotics portfolio and built an international presence, selling into markets outside China and establishing overseas operations and partnerships. This clinical business gave the company a reputation for practical, medically oriented robotics rather than consumer gadgets. As interest in humanoid robotics accelerated globally, Fourier moved into general-purpose humanoid robot development. The company developed humanoid platforms aimed at research, embodied-AI experimentation, and future service applications. This shift broadened its brand from a rehabilitation-robotics specialist to a broader robotics platform company, and it placed Fourier among the Chinese humanoid robotics firms attracting international attention. Today Fourier presents itself through its official website, fftai.com, under the tagline "傅利叶 · Fourier · 以机器人科技赋能生活" — robotics technology that empowers life. The company remains privately held, with its headquarters in Shanghai and operations reaching international markets. Its history reflects a common trajectory in Chinese robotics: starting from a focused clinical application and expanding toward general-purpose robotic platforms as the technology and market matured.
