Charles Kantor, former cofounder and CEO of Paris-based H Company, has unveiled Blackfuel, a new AI neocloud startup focusing on inference workloads. The venture comes as Kantor exits his previous agentic AI startup, which faced market challenges. Blackfuel aims to provide specialized cloud infrastructure for AI inference, addressing growing demand for efficient compute resources.

The launch marks Kantor's return to the AI infrastructure space after departing H Company. Industry observers note the timing aligns with increased enterprise adoption of AI inference technologies.
