phospho (YC W24)
"We give brains to robots."
French AI robotics startup (YC W24) providing open-source phosphobot toolkit and hardware kits to train Vision-Language-Action models on low-cost robot arms.
phospho (YC W24) is a Paris-based AI robotics company founded in 2023 by Pierre-Louis Biojout and Paul-Louis Venard. Backed by Y Combinator (Winter 2024) and Elaia Partners, the company raised €1.7 million in January 2024. Initially focused on LLM analytics, phospho pivoted to AI robotics with its flagship product phosphobot — an open-source Python/TypeScript toolkit that allows software engineers to control robots, record datasets, and train AI models even on low-cost hardware.
The platform supports Vision-Language-Action (VLA) models including BB-ACT, a 3.1B-parameter model conditioned via text prompts for robot arm tasks. phospho also sells developer hardware kits through its shop at robots.phospho.ai and offers a PRO subscription (€35/month) with cloud AI training, VR teleoperation, and advanced model support. As of 2026, over 2,000 robots run phosphobot and more than 1,000 AI models have been trained on the platform. Clients and users include engineers from NVIDIA, Hitachi, rerun.io, and comma.ai.
The company operates with a small team split between San Francisco and Paris.
