Summary

 

Flexion Robotics was founded in January 2025 by Nikita Rudin (CEO), David Hoeller (CTO), Julian Nubert, and Fabian Tischhauser, all with backgrounds in Nvidia research and ETH Zurich robotics. The company’s mission is to replace brittle, task-specific robot code with a scalable autonomy stack that enables humanoids to reason, perceive, and act in the real world.  

 

Flexion’s platform integrates:  

- Language-level reasoning (robots can follow natural language instructions)  

- Vision-language-action motion generation (robots interpret visual input and act accordingly)  

- Transformer-based whole-body control (robots coordinate limbs dynamically, not via pre-scripted routines)  

 

Editorial:

 

Flexion positions itself as a “picks-and-shovels” company in the humanoid race—instead of building robot hardware, it develops the intelligence layer that makes humanoids useful. This approach appeals to investors who see software as more scalable than manufacturing.  

 

The company raised $50 million in Series A funding (Nov 2025), led by DST Global Partners, with participation from NVentures (Nvidia’s venture arm), Redalpine, Prosus Ventures, and Moonfire Ventures. Flexion plans to expand into the U.S. Bay Area, scaling its compute, simulation, and robot fleets.  

 

By focusing on reinforcement learning, multimodal AI, and embodied intelligence, Flexion aims to become the default autonomy stack provider for humanoid robots worldwide.
