Petr Sibirtsev
Founder & developer — based in Israel
If it doesn't hold up the thousandth time you hit generate, it isn't finished.
Petr started VocalLab in November 2025, after one too many projects stalled at the voice-over stage. What began as a tool he built for himself now serves more than 20,000 users — funded entirely by the people who pay for it, with no investors and no ad budget.
He writes the code, talks to customers, and decides what ships next — which is why the roadmap is public and feedback goes straight to the person building the product. You can reach him directly at hi@vocallab.ai.
