Gradium raises $100M seed, Nvidia invests
Paris-based AI voice startup Gradium reopened its seed round to new investors, including Nvidia, and has raised $100 million in total for the round. The company says it will use the funding to open a Bay Area office and hire talent there. Gradium launched from stealth in December with an initial $70 million from investors including FirstMark Capital, Eurazeo, DST Global Partners, Eric Schmidt and Xavier Niel. The startup was spun out of French AI lab Kyutai and is co-founded by researcher Neil Zeghidour. Gradium builds voice AI models designed to deliver voice at scale with ultra-low latency and says it has secured customers such as Renault. Competitors named include ElevenLabs and major model makers like Google.
Significant venture funding for a voice-AI startup (and Nvidia participation) signals continued investment and competition in voice models, but the news is not industry-shifting.

Major Funding Wave Fuels Voice AI Startups
Investors have backed a wave of voice-AI companies with multiple large funding rounds, signaling strong interest in voice as an AI interface and a prominent use case in customer support. Recent rounds include ElevenLabs’ $500M Series D at an $11B valuation, Decagon’s $250M Series D led by Coatue and Index, Deepgram’s $130M Series C, and Paris-based Gradium’s $70M seed. Startups building voice models and orchestration software (e.g., Phonic) are attracting follow-on capital, and existing customer-support vendors like Netomi are adding voice capabilities and courting large enterprises. Major labs are also engaging unevenly: OpenAI’s voice efforts are expected to surface in Q1, while Anthropic’s CPO has voiced skepticism about voice as the next breakout medium. Early-stage VCs continue to target vertical, regulated-market voice support startups where founders can hold domain advantage.
Treble raises $18M for voice simulation platform
Treble Technologies, a Reykjavík-based startup founded in 2020, has raised $18 million (approximately €15 million) in a Series A-2 extension round led by Paladin Capital Group, with participation from KOMPAS VC, Frumtak Ventures, and the European Innovation Council Fund. The company provides a cloud-based platform using physics-based acoustic simulation to model sound behavior in real-world spaces, generate synthetic audio datasets, and create digital twins of rooms, vehicles, and devices. This accelerates prototyping from months to days for clients like Amazon and Logitech. With this funding, Treble's total raised exceeds $40 million (about €36 million). The new capital will drive expansion into physical AI, world models, and voice interfaces in wearables and robots, as well as support US market growth.
Groq Raises $650M, Re-staffs After Nvidia Deal
Groq announced a $650 million funding round on June 22, 2026, roughly six months after Nvidia signed a non-exclusive licensing agreement for Groq’s technology and hired away founder Jonathan Ross, president Sunny Madra, and other employees. Groq did not disclose a new valuation; it was last valued at $6.9 billion after a $750 million round in September 2025. Following the Nvidia transaction — which included Nvidia launching an inference hardware system called the Nvidia Groq 3 LPX — Groq pivoted to its neocloud inference business, which it says operates 13 data centers across multiple regions and serves over five million developers and thousands of AI companies. The company has hired new executives including Doug Wightman as CEO (he stayed on after the Nvidia deal), Alan Rice as COO, Sinclair Schuller as CTO, and Rakesh Malhotra as CPO. Groq continues to market its Language Processing Unit (LPU) technology for inference via cloud and on-prem offerings.
