H Company is a Paris agentic AI startup founded in 2024, known for computer use agents it calls androids, which operate a web browser as a person would. It is a member of Nvidia's Nemotron coalition alongside Mistral. Its entire founding team has left within two years: three of the five founders departed early, chief executive Charles Kantor was removed in 2025, and co founder and chief technology officer Laurent Sifre, previously a principal scientist at DeepMind, left at the start of 2026 and has joined a Microsoft AI research team in Paris. The company has been rebuilt under Gautier Cloix, former managing director of Palantir France, using deployed engineers placed with customers to drive adoption.
H Company released two Holo4 models that can operate graphical interfaces, run code and call software tools across desktop, web and mobile environments.
Laurent Sifre has joined a Microsoft AI research team in Paris after leaving H Company at the beginning of 2026.
H Company has launched a suite of next-generation autonomous AI agents, including Runner H, Surfer H, and Tester H, aimed at enhancing task execution and automation for enterprises and consumers.
