H is a frontier AI research lab and agentic platform founded in Paris, building technology to help businesses automate work across existing software and systems. Its computer-use agents can interact with desktop apps and browsers by clicking and typing, without requiring companies to rebuild their infrastructure or create new integrations. H offers three routes for customers: enterprise deployments with forward-deployed engineers who learn a company’s systems and develop custom agents; the Agents API, SDK, MCP and CLI for builders; and the Models API for direct access to its multimodal Holo models.

The platform supports browser and desktop environments, while Holo models can be incorporated into developers’ own agent workflows. H also provides HoloTab, a free Chrome extension that lets users try computer-use agents on tasks such as drafting email replies or preparing for a meeting. Its research includes models, publications, benchmarks and datasets focused on AI that can take action in real-world environments
