London-based voice cloning startup ElevenLabs has raised US$180 million in a series C funding round, increasing its valuation to US$3.3 billion.

The round was co-led by Andreessen Horowitz and Iconiq Growth, with participation from NEA, World Innovation Lab, Valor, Endeavor Catalyst Fund, and Lunate.

Founded in 2022 by Piotr Dabkowski and Mati Staniszewski, former employees of Google and Palantir Technologies, ElevenLabs develops AI tools for creating synthetic voices in multiple languages and emotional tones.

The company plans to use the funding to advance its research in voice AI, introduce new products, and expand its developer tools.
