Overview
- Walden disclosed in mid-July 2026 that it raised a $300 million seed round that values the Cambridge startup at $1.1 billion and includes strategic investors such as Toyota, Deviation Capital, NVIDIA and Boeing.
- The company was spun out of the Toyota Research Institute and is led by MIT professor Russ Tedrake, with a founding team drawn from Toyota, Amazon Robotics and other established robotics groups.
- Walden’s partially humanoid machines pair an upper body with arms and head sensors to a wheeled base and, the company says, have been operating full shifts inside a Toyota plant since early 2026, handling tasks like kitting, loading and cleaning.
- The robots run so‑called large behavior models and use techniques descended from Diffusion Policy to learn from real work, which Walden says lets machines be retasked and improve on the job faster than traditional industrial robots.
- Walden plans to spend the new capital on product development, manufacturing capacity and commercial expansion into aerospace, semiconductors, electronics, logistics and life sciences, while the key test will be whether its systems keep up performance and safety outside tightly controlled pilot sites.
