What Lightberry does
We build brains for robots. We work with manufacturers like Unitree to make robots listen, speak, and act. You can program your robot out of the box by literally talking to it, no coding involved. Robots running Lightberry are emotionally intelligent, always on, and fully autonomous. Just like in Star Wars!

Company
Lightberry
The social brain for robots.
We build conversational AI brains that let robots listen, speak, and act based on spoken commands. Our software lets manufacturers like Unitree ship robots you can program simply by talking to them - no coding required. The robots are emotionally intelligent and fully autonomous, designed to operate out of the box in real environments.
We live in San Francisco, CA, and the company will remain based here after YC.
San Francisco is where our team is based and where much of the robotics and AI innovation is centered. Being here keeps us close to key partners and early users.
