Profile match
Inetum is a European digital services company founded in France in 1970 as Gfi Informatique and renamed in 2021 after its acquisition by the private equity firm Bain Capital. It provides consulting, application development, infrastructure and managed services to clients across roughly twenty countries, with particular strength in France, Spain, Portugal and Belgium and a large nearshore delivery base in Morocco and Eastern Europe. Alongside services the group publishes its own software for public administration, human resources and finance, which gives it recurring licence revenue that pure services competitors lack.
