About H Company

H Company builds and deploys autonomous enterprise agents that automate complex, end-to-end enterprise workflows on top of existing systems, with measurable ROI, powered by proprietary research and forward-deployed engineers. Built from Paris, H is the world leader in enterprise computer-use AI.

H represents the third wave of enterprise AI. The first wave answered questions (chatbots and LLMs); the second connected systems through APIs (classic agents and copilots). H's agents operate software interfaces directly: they see, understand and act on any digital interface (web, desktop, mobile and legacy systems) like a human operator, but at scale, without integrations or APIs.

Powered by its proprietary multimodal models (the Holo series), H's agents understand context, plan multi-step actions and execute tasks across complex enterprise environments such as ERPs, CRMs and internal tools. Holo3, built in-house through H's proprietary Agentic Training Flywheel, ranks #1 worldwide on the OSWorld-Verified benchmark at around one-tenth of the cost of competing frontier models.

H works closely with NVIDIA as part of the Nemotron coalition. Its Holotron-12B model, developed with NVIDIA, is engineered for high-throughput, large-scale agent deployment. H also partners with Samsung and AWS, including AWS European Sovereign Cloud for clients with sovereignty requirements.

H deploys its technology through forward-deployed engineers (FDEs) embedded with enterprise clients. They identify high-impact workflows, integrate agents into real environments and deliver results within weeks. The promise is ROI, not experimentation: clients have seen 2-3% savings on purchasing costs, 20-50% more sales capacity without additional hiring, and emergency room wait times cut in half. The platform is SOC 2 Type II certified, with European-hosted inference and zero data retention.

H also offers HoloTab, a Chrome extension that lets anyone give an instruction and watch an agent navigate websites, fill in forms and chain actions on their behalf.

H raised $220M in Europe's largest AI seed round, backed by Accel, AWS, Samsung, Bpifrance, Eric Schmidt, Bernard Arnault and Xavier Niel. The company has around 100 employees across Paris, London and New York, with teams from DeepMind, Meta, Microsoft, Mistral, McKinsey and Goldman Sachs.
