In a significant development, Gradium, a startup based in Paris that specializes in voice AI technology, announced on Thursday that it has reopened its seed funding round to attract new investors, including the tech giant Nvidia. The company has successfully raised a total of $100 million in this funding round.
Gradium intends to utilize this capital to establish a new office in the Bay Area, aiming to enhance its competitiveness in attracting top talent within the heart of the world's premier AI landscape. This move also underscores Gradium's recognition of the advantages that being located near influential AI entities such as Anthropic, Google, Meta, and OpenAI can offer, despite Paris also being a vital hub for AI innovation in Europe.
The startup made its debut in December by emerging from stealth mode with an initial investment of $70 million from a distinguished group of backers, which includes FirstMark Capital, Eurazeo, DST Global Partners, Eric Schmidt, and prominent French telecom magnate Xavier Niel.
Gradium was established as a spin-off from the French AI research facility Kyutai, which is also supported by Niel. Both Gradium and Kyutai share a co-founder in Neil Zeghidour, a researcher with an impressive background that includes positions at Google Brain, DeepMind, and Facebook.
The firm is focused on developing audio models that provide voice solutions with ultra-low latency, enabling AI voices to respond almost immediately without the frustrating delays that often plague conversations involving AI agents.
Despite facing fierce competition from other voice AI companies like ElevenLabs, which was valued at $11 billion in February, and established model creators such as Google's Gemini, Gradium appears to be making strides in the market. Since its launch, the startup reports having secured notable clients, including the well-known French automotive company Renault.
