About

Walden Robotics is a Cambridge, Massachusetts company building general-purpose robots powered by Large Behavior Models that learn tasks from real-world experience. Spun out of the Toyota Research Institute and led by MIT professor Russ Tedrake, its partly humanoid machines — an upper torso with two arms on a wheeled or fixed base — perform manufacturing and logistics tasks alongside human workers and are already in production use at a Toyota plant in North America. The company launched from stealth in July 2026 with roughly $300 million in seed funding at a $1.1 billion valuation from investors including Toyota, Deviation Capital, NVIDIA, Boeing, and Samsung Ventures.

Builds on the founding team's Diffusion Policy breakthrough at Toyota Research Institute — adapting image-generation diffusion models to teach robots manipulation — and pairs it with Toyota production expertise, so robots deliver value in real factories from day one rather than in demos.
