Fish Audio raises $50M seed to build AI voice models for creators and enterprises

AI voice startup Fish Audio has raised $50 million in a seed round to expand its expressive voice generation models. The company, which offers both open-source and paid API versions, serves creators and enterprises like HeyGen and Sanas.
Why it matters
The rapid funding highlights the growing demand for high-fidelity, steerable AI voice technology in both creative media and enterprise automation.
The market for AI-generated voice models is massive. Creative use cases require AI voice models to be more expressive, while enterprises looking to automate customer support and sales ops need them to be more steerable.
Palo Alto-based Fish Audio wants to cater to all of those use cases with its library of more than 15,000 natural language controls. Since launching last year, the startup today has more than 8 million people using the open-source or hosted versions of its models, and now generates annual recurring revenue of $21 million.
To continue building on that traction, the startup on Tuesday said it has raised $50 million in a seed round that was led by Coreline Ventures and Capital Today. The funding also saw participation from 359 Capital, Parable, Play Time, Alphalist Partners, Bayhouse Ventures, Carya Venture Partners, and HF0.
