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.
