Flexion Robotics

An ETH Zurich spin-off building an autonomy software stack for humanoid robots.

Flexion Robotics is a humanoid-robot software company headquartered in Zurich with an additional office in San Francisco. Co-founder and CEO Nikita Rudin did his PhD at ETH Zurich and later worked as an NVIDIA researcher, and is the lead author of legged_gym; CTO David Höller also came out of ETH and NVIDIA; and ETH Robotic Systems Lab professor Marco Hutter is a co-founder and advisor. The company doesn't build its own robot bodies; instead it aims to build a hardware-agnostic “autonomy stack” for humanoids, covering everything from understanding instructions and planning down to the low-level control for manipulation and walking, with an emphasis on training with reinforcement learning in simulation and transferring to the real robot. It released Reflect v0 in November 2025 and Reflect v1.0, aimed at long-horizon autonomous work, in June 2026; in July it announced sim-to-real research partnerships with Niantic Spatial and NVIDIA.
