Pitch deck: PyannoteAI raises $9 million for its voice AI platform
Apr 07, 2025 - businessinsider.com
Voice intelligence startup PyannoteAI has raised $9 million in a seed round led by Crane Ventures and Serena to enhance voice transcriptions using AI. Founded in 2024 by Hervé Bredin and Vincent Molina, the French startup focuses on "speaker diarization," which improves audio transcriptions by distinguishing between different speakers. The AI model is designed to handle complex, multi-speaker conversations, ensuring accurate transcriptions and understanding of intonation across various languages and use cases. PyannoteAI's technology is used for audio indexing, dubbing, and transcribing consultations, with clients including Gladia and MediVox.
The funding round also saw participation from Julien Chaumond of HuggingFace and former Meta and OpenAI researcher Alexis Conneau. With the new capital, PyannoteAI plans to expand its research team. The startup has attracted significant investor interest from Europe and the US, as the voice AI industry experiences rapid growth across infrastructure, applications, and models. The funding aligns with a previous report that PyannoteAI was in talks to raise around $10 million.
