Mateusz 'Mati' Staniszewski is a Polish technology entrepreneur and the co-founder and CEO of ElevenLabs. Born in Poland, he met his co-founder, Piotr Dabkowski, in high school, where they both shared a fascination with computer science and international technology.

Staniszewski established his professional reputation at Palantir Technologies, where he worked as a deployment strategist. In 2022, he and Dabkowski pooled their savings and quit their high-paying tech jobs to focus entirely on their vision for high-fidelity AI voice cloning.

• Core Company: ElevenLabs (AI Audio Platform).
• Origins: Polish-born entrepreneur who built a global unicorn between Warsaw and London.
• First Interest: Developed the idea for ElevenLabs after realizing the poor quality of dubbed films in Poland.

Mati Staniszewski’s career is defined by the meteoric rise of ElevenLabs, which became the world leader in generative AI audio. Under his leadership as CEO, the company developed a proprietary model capable of cloning voices with unprecedented emotional nuance.

In October 2025, private investors valued ElevenLabs at $6.6 billion, officially making Staniszewski a billionaire with an estimated 15% stake. By late 2025, the firm reached a $200 million annual recurring revenue (ARR) milestone, serving global partners including the Audi Revolut F1 Team.

• Strategic Achievement: Scaled the company from launch to a $6 billion valuation in just three years.
