Fish Audio raises $52M seed on $21M ARR for its open-source voice models

Fish Audio, founded by former Nvidia researcher Shijia Liao, raised $52M led by Coreline Ventures and Capital Today — a seed in label only, landing on $21M ARR and 8 million users. That puts a revenue-generating open-source contender into a crowded voice market against ElevenLabs and Cartesia. Consent is the weak point: creators alleged their voices were uploaded without permission, and takedowns now clear in under three minutes.

A community-centric approach can only become a durable advantage if creators trust the platform.

Why this matters

  • → Open-source voice AI reaching $21M ARR challenges closed competitors like ElevenLabs.
  • → Consent failures expose structural risk — takedown automation doesn't prevent unauthorized uploads.
  • → Massive voice model library (15K+ controls) and 8M users signal real product-market fit.
