Fish Audio Raises $50 Million Seed to Scale Voice AI

The funding will speed product and enterprise growth by expanding paid API access, widening open-source models, faster takedown tools, audio-understanding work.

Overview

  • The company announced the $50 million seed round on Tuesday to grow products and enterprise sales and said Coreline Ventures and Capital Today led the financing.
  • Fish Audio reports more than 8 million users and $21 million in annual recurring revenue from a mix of open-source releases and paid hosted APIs.
  • The startup sells an open-source model lineup while keeping its latest S2.1 Pro model behind a paid API and offers real-time streaming, instant voice cloning, and a creator marketplace.
  • After creator complaints about unauthorized voice uploads, Fish Audio automated its takedown process and says it will remove contested voice models in under three minutes when creators submit proof.
  • The company published low word-error-rate benchmarks for S2 and S2 Pro in March 2026 and plans to build audio-understanding and speech-to-speech models as it competes with established voice-AI firms.
