Gradium, a Paris-based startup specialising in voice AI models, has secured $100 million in seed funding from investors including tech giant Nvidia. This funding round brings the total amount raised by the company to $170 million, with $70 million having been secured in December 2025. The investment will be used to establish an office in the Bay Area, allowing Gradium to compete for talent in the region and strengthen its position at the heart of the world's leading AI ecosystem.
According to the company, the Bay Area is home to several leading AI organisations, including Anthropic, Google, Meta, and OpenAI. Gradium was founded by Neil Zeghidour, a researcher who previously worked at Google Brain, DeepMind, and Facebook, and was spun out of French AI lab Kyutai. The startup is working on audio models that deliver voice at scale with ultra-low latency, a key feature that differentiates it from competitors.
Gradium has already secured several big customers, including French auto manufacturer Renault. While the company faces competition from other voice AI startups like ElevenLabs, valued at $11 billion in February, it appears to be gaining ground. As the AI industry continues to grow, Gradium's success could have implications for the UK's tech sector, where AI is becoming increasingly important.
Regulatory bodies such as the UK's Information Commissioner's Office (ICO) and the European Union's AI Act are keeping a close eye on the development of AI technology, with a focus on ensuring that it is used in a way that respects individuals' rights and privacy. As the UK continues to develop its own AI strategy, the success of companies like Gradium could have a significant impact on the country's ability to compete in the global AI market.
While the immediate impact of Gradium's funding round may be felt by the company's existing customers and competitors, the long-term implications for the UK's AI sector could be significant. As the country continues to develop its own AI strategy, the success of companies like Gradium could have a major impact on the country's ability to compete in the global AI market.
