Raphael Mimoun is General Manager of Truecaller Israel and the architect behind the company’s AI voice products used by more than 400 million people each month.
Formerly the founder & CEO of CallHero, the AI phone assistant acquired by Truecaller in 2022, Raphael turned a small startup into a global feature now embedded in every Truecaller subscription and drove a 40 % jump in recurring revenue along the way.
A hands‑on technical leader with a decade in NLP and large language model engineering, he led the Microsoft Truecaller partnership unveiled at Microsoft Build 2024, where users first saw calls answered in their own cloned voice.
Today Raphael’s north star is simple: make every phone safe by democratizing AI call protection and giving users a trusted agent that never sleeps.
