The company, which emerged from stealth last December with an initial $70 million backing from heavyweights like Eric Schmidt and Xavier Niel, is now betting on geographic expansion. By planting a flag in the Bay Area, Gradium intends to compete for top-tier engineering talent currently clustered around rivals such as OpenAI, Meta, and Google. This move follows a period of rapid development for the firm, which spun out of the French research lab Kyutai under the leadership of former Google Brain and DeepMind researcher Neil Zeghidour.

Parisian Voice AI Startup Gradium Secures $100 Million Seed Extension
Paris-based Gradium has expanded its seed funding to $100 million with a fresh injection from Nvidia, signaling a strategic pivot toward the Bay Area. The startup aims to leverage this capital to establish a physical presence in the heart of the global AI ecosystem, directly challenging incumbents in the high-stakes voice model market.
Gradium specializes in ultra-low latency audio models designed to eliminate the mechanical pauses typical of current AI agents. Despite intense pressure from established players like ElevenLabs—which hit an $11 billion valuation earlier this year—and the multimodal capabilities of Google’s Gemini, the startup is gaining commercial momentum. The company reports early success in the enterprise sector, most notably signing French automaker Renault as a client. The additional funding from Nvidia serves as both a financial cushion and a technical validation for Gradium’s architectural approach to real-time voice synthesis.
