About Fourier

Fourier was founded in 2015 in Shanghai as a maker of rehabilitation robots and exoskeletons; founder and CEO is Gu Jie (Alex Gu). The company's rehab products are used by more than 2,000 institutions in 40 countries — its humanoids build on that experience.

The humanoid line began with GR-1 (2023), continued with GR-2 (2024, 175 cm, 53 DoF) and the open-source N1 (2025). GR-3 (launched 6 August 2025, deliveries from October 2025) is the first full-size humanoid designed for eldercare and rehabilitation: soft shell, 31 touch sensors, eye displays, 55 DoF, 3 h runtime. It made its US debut at CES 2026.

Investors are SoftBank Vision Fund 2 (Series D, 2022), Prosperity7 Ventures, IDG Capital and Guoxin (Series E of about RMB 800M, 2025); the company has about 600 employees and, according to available data, has delivered hundreds of GRx humanoids.

For ROBOTio, Fourier is a brand for healthcare and social-care clients. It has no official EU distribution or service, which matters for care deployments — so we watch GR-3 and offer purchase advice, not hire.
