Next-generation ATS platform for French recruitment and talent management

Software Development Paris, Île-de-France 11–50 employees Founded 2019 Privately Held

Leihia builds a SaaS recruiting platform positioned in France's top-5 ATS solutions. The tech stack reveals an organization mid-migration: actively adopting .NET Core and Keycloak while phasing out PHP, structured around microservices and identity infrastructure. Pain points cluster around security, authentication complexity, and regulatory compliance—priorities reflected in heavy hiring across security (124 roles) and engineering (138 roles), suggesting the platform is investing in hardening and modernization rather than pure feature expansion.
