| Date / Milestone | Business Line | Detail |
|---|---|---|
| 2015. Fourier Intelligence founded | Rehabilitation robotics | Alex Gu founds the company; initial product is lower-limb rehabilitation exoskeleton for stroke + spinal-injury recovery |
| 2017-2020. Rehab product line expansion | Rehabilitation | ExoMotus M4 (lower-limb) + Maximo M4 (variant) + ArmMotus EMU (upper-limb) + RehabHub IoT platform; expansion to international markets |
| 2020-2022. ~2,000+ hospitals + rehab centers in 50+ countries | Rehabilitation | Cumulative installed base; primary revenue source; profitable line by ~2022 |
| 2023-07. GR-1 humanoid unveiled at WAIC Shanghai | GR-series humanoid (industrial) | First Fourier humanoid; 5 ft 8 in; 40 kg; cable-driven actuator design; not commercially deployed in 2023 |
| 2024-04. GR-1 commercial pilots | GR-1 | Limited commercial pilots in industrial + research applications; cumulative ~50 units shipped through 2024 |
| 2024-09. GR-2 unveiled | GR-2 | 53 body DoF (up from 40 in GR-1); 12 DoF per hand with 6 array-type tactile sensors per hand; 2-hour quick-swap battery; targets industrial logistics + research |
| 2025-01. Series E $109M led by SoftBank ($1.1B post-money) | Both lines | SoftBank $54.7M lead investment; first major US-style funding; targets GR-series scale-up + international rehab expansion |
| 2025-Q2. GR-2 industrial pilots announced | GR-2 | Chinese auto OEM pilot (BYD or Geely; industry reports differ); Japanese research-institution pilot; targets ~200 GR-2 units shipped 2025 |
| 2025-Q4. RehabHub IoT platform expanded | Rehabilitation | Cloud-connected rehab platform expansion; integrates AI-driven exercise programming; Fourier characterizes as 'precursor to AI-enabled humanoid rehab caregivers' |
| Editorial. Bi-modal economics question | Strategic context | Fourier reportedly generates ~$100M+ annual rehab revenue (private, not audited) with mid-teens gross margins. GR-series industrial humanoids are R&D + customer-pilot-stage with effectively no commercial revenue through 2025. The cross-subsidy lets Fourier sustain GR-series investment longer than pure-play industrial competitors at the same funding stage. The SoftBank Series E was the inflection point where outside capital meaningfully accelerated GR-series development independent of rehab cash flow |
