Olivier Pailhes co-founded Aircall in Paris in 2014 with Jonathan Anguelov, Pierre-Baptiste Bechu and Xavier Durand. The product was a cloud phone system for small and mid-sized companies, linked to the CRM and helpdesk tools sales teams already used.
In 2017 the company moved to New York to win US customers, and revenue tripled that year. In 2018 it raised $29 million from Draper Esprit, NextWorld Capital and Newfund.
In May 2020 Aircall raised $65 million, and in June 2021 it raised $120 million in a round led by Goldman Sachs, becoming the 16th French unicorn. By 2022 annual recurring revenue was above $100 million.
In 2024 the company marked its tenth anniversary and opened a San Francisco office. In 2026 it bought Vogent in May and Piper AI in June as it moved toward AI voice agents. Aircall is privately held.
