Value proposition
General-purpose robots that are already deployed in real production environments doing useful work from day one, powered by Large Behavior Models (LBMs) that enable continuous learning through real-world practice without manual reprogramming
Products and solutions
General-purpose humanoid robots for manufacturing and logistics, Full-stack Physical AI platform combining hardware, software, Large Behavior Models (LBMs), and application layer, Robot-as-a-Service (RaaS) deployment model
Unique value
Only Physical AI company with general-purpose robots already performing real production work in a major automotive factory (Toyota North America plant) within months of founding, powered by proprietary Large Behavior Models (LBMs) pioneered at Toyota Research Institute
Target customer
Manufacturing and logistics companies in automotive, aerospace, semiconductors, electronics, logistics, and life sciences industries facing labor shortages and increased demand
Industries served
Automotive, Aerospace, Semiconductors, Electronics, Logistics, Life Sciences
Technology advantage
Proprietary Large Behavior Models (LBMs) — a frontier model class for physical AI that lets robots learn new tasks through demonstration and continuous practice; Diffusion Policy neural network adaptation for robot task learning; decade of foundational AI and robotics research from Toyota Research Institute, MIT, Stanford; robots already deployed in production at Toyota North America
How they differentiate
Differentiated by: (1) Real-world deployment — robots already doing useful work in a Toyota factory since February 2026, moving from pilot to production in under 2 months; (2) Large Behavior Models (LBMs) — a frontier AI model class for physical tasks, analogous to LLMs for language; (3) Full-stack approach — building hardware, software, AI models, and application layer in-house; (4) Robot-as-a-Service model rather than selling hardware; (5) Wheel-based design for immediate safety compliance in factories while delivering value
Main competitors
Tesla (Optimus), Figure AI, Boston Dynamics (Atlas), Apptronik, Tutor Intelligence
Key partnerships
Toyota Motor Corporation (strategic partner, lead investor, first production deployment at Toyota North America plant), NVIDIA (investor and likely hardware/AI platform partner), Boeing (investor and strategic partner in aerospace), Samsung Ventures (investor), CoreWeave (investor and cloud infrastructure partner)
Notable customers
Toyota Motor Corporation (first production deployment at a Toyota plant in North America since February 2026)
Major milestones
January 2026: Company founded, spun out of Toyota Research Institute, February 2026: First general-purpose robots deployed doing real production work at a Toyota plant in North America (pilot to production in under 2 months), July 15, 2026: Emerged from stealth with $300M seed round at $1.1B valuation — one of Boston's largest robotics deals ever
Growth metrics
$1.1B post-money valuation at seed stage; robots deployed in production at Toyota North America within 2 months of founding; $300M raised in single seed round
Market positioning
Premium full-stack Physical AI company positioned as a leader in the general-purpose humanoid robotics space, with a $1.1B valuation at seed stage — one of the largest robotics deals in Boston history. Competes with Tesla Optimus, Figure, Apptronik, Boston Dynamics, and Tutor Intelligence by emphasizing real-world production deployment over demos.
Geographic focus
North America (initial Toyota plant deployment); global manufacturing and logistics markets
Patents and IP
Builds on foundational IP from Toyota Research Institute including Diffusion Policy and Large Behavior Models (LBMs); Adrien Gaidon (CSO) holds 100+ patents in Physical AI, Computer Vision, Autonomous Driving, and Robotics
