Flexion Robotics builds the autonomy stack for humanoid robots — from command to control, from manipulation to locomotion, across any hardware and task. Founded by former NVIDIA and ETH Zurich reinforcement-learning researchers (Nikita Rudin, David Höller, Julian Nubert), the Zurich- and San Francisco-based company uses large-scale simulation and reinforcement learning to train generalizable robot policies that transfer to real-world hardware. Its Flexion Reflect model line targets long-horizon autonomous humanoid work. The company raised $50M and is backed by Prosus Ventures. Flexion does not currently expose a public developer API.
