Paris-Based AI Voice Startup Gradium Raises $100M Seed Round Backed by Nvidia

Gradium, a Paris-based AI voice startup, has closed a $100 million seed round with Nvidia among its backers — an unusually large raise at the seed stage for a European AI company. The funding positions Gradium as a well-capitalized entrant in the competitive AI voice space.

The company plans to use the capital to open an office in the Bay Area, targeting access to top AI talent and what it describes as "the heart of the world's leading AI ecosystem." The transatlantic expansion signals Gradium's ambition to compete directly with established players in the U.S. market.
