Fourier Intelligence

What Fourier Intelligence does

Fourier Intelligence (rebranded to "Fourier" in 2023) is a Shanghai-headquartered full-stack robotics company founded in 2015 by Alex Gu, operating two integrated product pillars. The first is the GRx humanoid robot series — a bipedal, general-purpose family comprising GR-1 (the industry's first mass-produced humanoid, 2023), GR-2 (2024), GR-3 "Meow-bot" (2025), GR-3C "Cosmo" (2025), and the open-source Fourier N1, complemented by the FDH-6 6-DoF dexterous hand. The second is the Fourier Rehab clinical line, anchored by the AI-driven RehabHub platform integrating 30+ specialized devices (ArmMotus EMU/M2 Pro, ExoMotus M4, AnkleMotus M1A, WristMotus M1W, PelmaMotus, CycleMotus, OTParvos, MetaMotus Galileo) deployed across 2,000+ institutions in 40+ countries.

Underlying technology is vertically integrated: proprietary FSA and FSA 2.0 actuator modules, a Pure Vision Perception Solution using BEV + Transformer + Occupancy Network across six RGB cameras, 12-DoF dexterous hands with tactile sensing, hot-swappable battery systems, and a multimodal interaction stack (four-mic array, RGB + structured-light camera, 31 distributed pressure sensors) governed by an LLM-powered dual-path response architecture. Developer tooling includes the Fourier Toolkit SDK with ROS, NVIDIA Isaac Lab, and Mujoco support, plus the FourierActionNet open-source dataset.

The business model is primarily hardware sales (premium-priced humanoids and rehabilitation devices) supplemented by software/SDK licensing through the EXOPS open platform, professional services for customization and deployment (bank lobby, automotive factory, clinical integrations), and turnkey rehab ecosystem solutions. Go-to-market blends enterprise field sales into hospitals and research institutions, channel partnerships (HTPG in the U.S., Kurage in Europe, Rymo Technologies in India), community-led developer engagement through Fourier Nexus, API-first tooling for developers, and event-driven launches at CES, MEDICA, and IFNRCON. Capital structure remains private, with disclosed funding led by SoftBank Vision Fund (2022, ~$63.3M), Prosperity7 Ventures (Aramco Ventures, 2021 and 2025), and Vision Plus Capital (2020). The company is headquartered in Shanghai with regional offices in Singapore and Kuala Lumpur.

Core offering

Fourier Intelligence designs, manufactures, and sells full-stack robotics products spanning two pillars: (1) the GRx bipedal humanoid robot series (GR-1, GR-2, GR-3 Meow-bot, GR-3C Cosmo, open-source N1) and the FDH-6 dexterous hand, and (2) the Fourier Rehab clinical line anchored by the RehabHub AI-driven platform that integrates more than 30 specialized rehabilitation devices (ArmMotus, ExoMotus, AnkleMotus, WristMotus, PelmaMotus, CycleMotus, OTParvos, EXOPS) plus the MetaMotus Galileo biomechanics and mixed-reality training system. Products are deployed across hospitals, rehabilitation clinics, research institutes, and enterprise customers in more than 40 countries.

Product overview

Fourier (formerly Fourier Intelligence) is an industry-leading proactive AI robotics company delivering a full-stack robotics portfolio built around two integrated pillars. The first is the GRx humanoid robot series — a bipedal, general-purpose product family comprising the GR-1 (first mass-produced humanoid), GR-2 (next-generation with 12-DoF dexterous hands), GR-3 "Meow-bot" (the first Care-bot for wellness companionship), GR-3C "Cosmo" (reinforced assistive variant), and the open-source Fourier N1 — accompanied by the FDH-6 six-degree-of-freedom dexterous hand as an add-on module. The second pillar is the Fourier Rehab clinical line, anchored by the RehabHub™ AI-driven rehabilitation platform, which integrates more than 30 specialized devices including the ArmMotus™ EMU (3D cable-driven upper-limb robot, 2023 IERA Award winner), ExoMotus™ M4 (lower-limb exoskeleton), ArmMotus™ M2 Pro, AnkleMotus™ M1A, WristMotus™ M1W, PelmaMotus™, CycleMotus™ Series, OTParvos™ digital OT system, EXOPS™ open research platform, and Fortis™ / AirFortis Series — all accessible alongside the MetaMotus™ Galileo biomechanics and VR training platform. Together, these products serve more than 2,000 institutions across over 40 countries, applying embodied AI to humanoid interaction scenarios and clinical neurorehabilitation.

Direct peers

• Unitree Robotics: China-based humanoid and quadruped robotics company with a comparable product ladder (H1, G1 humanoids) and a similar mass-production, value-pricing positioning. Competes directly with Fourier's GRx series in both Chinese and global research/enterprise accounts.
• UBTECH Robotics: Hong Kong/China-listed humanoid and service-robotics company (Walker S, Cruzr) targeting commercial and industrial deployments. Direct competitor in bipedal humanoids and shares Fourier's enterprise sales motion into automotive and public-facing environments.
• Agility Robotics: U.S.-based humanoid robotics company behind Digit, focused on logistics and warehouse use cases. Direct competitor in general-purpose bipedal humanoids targeting enterprise customers, with comparable embodied-AI and manipulation roadmap.
• Figure AI: U.S. humanoid robotics startup developing general-purpose bipedal robots (Figure 01/02) for commercial and industrial use. Competes head-to-head with Fourier's GRx for industrial pilots and embodied-AI talent, with significantly larger capital base.
• Apptronik: Texas-based humanoid robotics company (Apollo) targeting industrial and commercial applications. Competes in the same general-purpose humanoid category as Fourier's GRx, with deep university research roots similar to Fourier's academic positioning.
• 1X Technologies: Norway-based humanoid robotics company (NEO Beta) backed by OpenAI, focused on consumer and home-applied humanoids. Competes with Fourier in the embodied-AI humanoid space and shares an emphasis on safe, human-centered interaction.
• Ekso Bionics: U.S.-listed exoskeleton and rehabilitation robotics company (EksoNR, Ekso Indego) competing directly with Fourier Rehab's ExoMotus M4 and broader lower-limb exoskeleton portfolio in stroke and spinal-cord-injury gait rehabilitation.
• Hocoma: Swiss rehabilitation robotics company (Lokomat, Armeo) and a global incumbent in clinical neurorehabilitation. Competes with Fourier Rehab in upper-limb, lower-limb, and balance/gait robotics sold to hospitals and research institutions worldwide.

Broad incumbents

• Tesla (Optimus): Tesla's Optimus humanoid program leverages Tesla's in-house AI compute, manufacturing scale, and consumer brand. While a different corporate parent, it is the highest-profile competitor shaping enterprise customer expectations for general-purpose humanoids that Fourier must compete against.

Emerging players

• Sanctuary AI: Canada-based humanoid and embodied-AI company (Phoenix) with a carbon-AI control system focus. Emerging competitor with partial overlap to Fourier's GRx in bipedal humanoids and LLM-driven interaction, particularly relevant for industrial and customer-service pilots.
