Biography

Mateusz "Mati" Staniszewski is cofounder of Warsaw and London-based AI voice agent startup ElevenLabs.

Private investors valued the company at $6.6 billion in October 2025. Staniszewski and his billionaire cofounder Piotr Dabkowski each own an estimated 15% stake.

The high school friends from Poland teamed up to experiment with artificial intelligence while Staniszewski was working at Palantir and Dabkowski was working at Google.

The pair pooled their savings and quit their jobs to work full-time on ElevenLabs in 2022.

The firm has no traditional titles, but Staniszewski acts as CEO and Dabkowski acts as research head.
