ElevenLabs

ElevenLabs is a London-headquartered AI audio platform that has built one of the world's most advanced voice-synthesis stacks. Its products span text-to-speech in 70+ languages, instant and professional voice cloning, an automated dubbing studio across 90+ languages, real-time conversational voice agents, AI sound effects and an audio production suite; the ElevenReader app offers a large catalogue of licensed human-narrated audiobooks. Enterprise clients range from Deutsche Telekom and Revolut to the Ukrainian Government, and in 2026 ElevenLabs integrated its voice capabilities into IBM's watsonx Orchestrate.

Founded in 2022 by Polish childhood friends Mati Staniszewski (CEO, ex-Palantir) and Piotr Dąbkowski (CTO, ex-Google), the company raised a $2M pre-seed from European funds Credo Ventures and Concept Ventures, then scaled rapidly: a $19M Series A (2023), $80M Series B at $1.1B (2024), $180M Series C at $3.3B (2025), and a $500M Series D at an $11B valuation led by Sequoia Capital (2026), with a later extension adding BlackRock, NVIDIA and others. With cumulative funding over $781M and ARR past $500M, ElevenLabs is among the fastest-growing AI companies in Europe.
