Paris-based AI voice startup Gradium has raised $100 million in seed funding, with backing from Nvidia, giving the company significant resources to build and scale its voice AI technology.
The new capital will help Gradium expand beyond Europe by opening an office in the Bay Area, placing it closer to one of the world’s densest hubs for AI research, engineering talent, and startup partnerships.
Why it matters
Voice AI is becoming an increasingly important interface for software, devices, customer service, accessibility tools, and creative workflows. A large seed round like this suggests investors see major potential in more natural, responsive, and useful AI voice systems.
- Global expansion: Gradium is positioning itself across both Paris and the Bay Area.
- Talent growth: The funding supports recruitment in a highly competitive AI hiring market.
- AI ecosystem support: Nvidia’s backing adds credibility and strategic weight.
While the company is still early, this raise is a positive signal for Europe’s AI startup scene and for the broader push toward more capable voice-based AI products.
