H Company (formerly Holistic AI) is a Paris-based frontier AI research lab and agentic platform founded in 2023 by five researchers, four of whom came from Google DeepMind. The company's core thesis is that AI should not merely reason about tasks but take direct action inside real-world digital environments — clicking, typing, and navigating software interfaces the way a human operator would, without requiring API integrations or infrastructure rebuilds.

The company's flagship product line, the Holo model series, powers computer-use agents capable of operating across desktop, web, mobile (Android), code sandboxes, MCP servers, and business APIs through a single unified model. The latest release, Holo4 (September 2026), achieves 85.2% on the OSWorld benchmark at $0.08 per task, making it among the most cost-efficient frontier computer-use models available. H also offers HoloTab (a Chrome extension for consumer-facing agent use), a cloud-hosted Agents API, a Models API with OpenAI-compatible endpoints, and enterprise deployments staffed by forward-deployed engineers.

H's go-to-market targets Europe's largest enterprises, deploying agents directly on existing production systems — including legacy mainframes and modern SaaS stacks — without rebuilding their technology stack. Enterprise customers include FDJ UNITED, and the company holds SOC 2 Type II, ISO 27001, and GDPR compliance certifications. In June 2026, H joined the NVIDIA Nemotron Coalition to advance open frontier model development.

Following a period of significant leadership change — including the departure of three co-founders in August 2024 and the transition of the CEO role from Charles Kantor to Gautier Cloix (former Palantir France CEO) in June 2025 — H has stabilized under new management with offices in Paris, London, San Francisco, and New York, and approximately 75–200 employees across its global hubs.
