Laurent Sifre, co‑founder of Paris‑based agentic AI startup H Company, has left his post as chief technology officer. He will serve as head of the company’s scientific council, a non‑operational advisory position. The decision was communicated to staff in a memo, stressing continuity of the engineering roadmap.

The restructuring arrives months after H Company closed a $428 million Series C round led by European venture funds, valuing the startup at over €2 billion. That capital infusion fueled a hiring spree for AI talent and accelerated R&D on its proprietary agentic platform. Board member Claire Dupont said the shift supports autonomous AI.

Investors will watch how the new scientific council influences product roadmaps and whether the CTO vacancy slows delivery schedules. Existing leadership, including the CEO, assures continuity, but Sifre’s technical reputation anchors credibility with research partners. Clients expect the council to boost model robustness.
