Our Story

At YeldaAI, our team is like a symphony orchestra. Each member plays a crucial role in creating a perfect harmony between technology and customer service.

  • 2018

    Born from a real problem

    FNAC, Sodebo, FM Logistics — our first clients didn't want a chatbot. They wanted something that could actually talk to their customers. We launched YeldaAI from the Mines-Telecom incubator in Paris to build exactly that, backed by a $275K pre-seed round and a spot at Station F.

  • 2018

    Station F & Future 40

    In our first year, we were admitted to Station F's Founder Program and named one of its 40 most promising startups — out of 1,000. Early validation that the problem was real, and so was our approach.

    Two new frontiers: healthcare & public sector

    Covid accelerated everything. Pharmacies, hospitals, and medical practices needed to handle surging call volumes overnight. At the same time, town halls and municipalities began deploying YeldaAI to modernize citizen services — a sector we've been building for ever since.

  • 2022

    Into the public sector at scale

    WHO, IARC, the French Civil Aviation Authority, SFR. YeldaAI is invited to the Mayors and Communities Show as a reference voice AI platform for public institutions.

    The Generative AI shift

    We were the first telephony solution to integrate generative AI with intent detection, deployed entirely by voice. Not a feature update — a full architectural leap that redefined what a voice agent could do.

  • 2024–Now

    From automation to measurable impact

    MMV generates €245K in bookings from recovered off-hours calls. Ohm Energie handles 500,000 calls a year with a 4.5/5 satisfaction score. JP Home processes 50,000 calls a month with a 95-second average handle time. YeldaAI wins 3 IAwards 2025, including Best AI ChatBot/VoiceBot. The question is no longer whether AI can handle customer calls — it's how much value it creates.
