Gradium voice AI startup extends seed to $100M+ with $30M NVIDIA-backed tranche
French voice AI startup Gradium has raised approximately $30 million in fresh funding, extending its seed round to over $100 million just seven months after launching. New investors in this extension include NVIDIA, joining prior backers Firstmark Capital and Eurazeo, which led a $70M first tranche last year. Gradium also counts French billionaires Xavier Niel and Rodolphe Saadé, and former Google CEO Eric Schmidt as early investors.
Gradium builds AI models and tools for real-time text-to-speech, speech-to-text, and voice translation, with models optimized for edge devices like laptops and phones. The startup publishes new voice models roughly monthly—a pace the cofounders say outpaces competitors' typical 6–12 month development cycles. Enterprises across healthcare, customer service, and gaming are adopting the technology. The fresh capital will fund a San Francisco office and accelerate research and product development.
Voice AI funding is accelerating across Europe: Sifted data shows AI-native voice startups raised €536M in H1 2026, up 50% from €360M in H1 2025. NVIDIA's participation signals confidence in voice as a foundational agent capability, particularly as inference moves to edge and on-prem deployments.
