Flexion Robotics is a Swiss robotics intelligence company building the autonomy stack that humanoid robots need to act reliably in the real world. Where many robotics companies focus on hardware, Flexion concentrates on the software layer: command understanding, perception, manipulation, and locomotion that can run across different robot bodies and tasks. The company describes its goal as building the intelligence layer, sometimes called the brain, that turns capable hardware into useful general-purpose machines.
The company was founded in early 2025 by former NVIDIA researchers, with CEO Nikita Rudin leading a team drawn from ETH Zurich, NVIDIA, Meta, Google, Tesla, and Amazon. Their technical approach centers on reinforcement learning and simulation-to-reality transfer, training control policies in large-scale simulation before deploying them on physical robots. This sim-to-real pipeline is paired with synthetic vision-language-action data and transformer-based full-body controllers, allowing robots to interpret natural language tasks and execute them with coordinated whole-body motion.
A core thesis behind Flexion is that the central bottleneck in humanoid robotics is not hardware but the enormous amount of human teleoperation and demonstration currently required to teach robots individual skills. By generating training data synthetically and learning generalizable policies, Flexion aims to dramatically cut the human effort needed to bring new tasks online. The stack is intended to be hardware-agnostic so that humanoid makers can adopt it rather than building autonomy from scratch.
Flexion raised a $50 million Series A in November 2025 led by DST Global Partners, with participation from NVIDIA's NVentures, Redalpine, Prosus Ventures, and Moonfire, following a $7.35 million seed round and bringing total funding to roughly $57 million. The capital supports expanded R&D in Zurich, more compute and robotic infrastructure, and a US presence as the company scales its intelligence platform for the humanoid market.
