What HN Group does

HN Group, operating commercially as HN Services, is a privately-held French Entreprise de Services du Numérique (ESN) founded in 1983 by Michel Hochberg and headquartered in Charenton-le-Pont. The group provides IT consulting, technical assistance, application maintenance (TMA), managed services, and dedicated service centers across mainframe (COBOL, DB2, JCL, CICS, z/OS) and open systems (Java/J2EE, .NET, Angular, Spring Boot) stacks, alongside CRM (Salesforce, Microsoft Dynamics), DevOps, and UX/UI design through its 'HN Factory' offering. It operates a 24/7 supervision and production-management practice for clients with critical IS environments, including a predictive-monitoring capability developed with TELECOM PARIS, ESIEE, and ANR under the 'IA by HN' banner.

The group generates revenue primarily through professional-services engagements billed on Technical Assistance, Competence Center, or Service Center contractual models, typically multi-year, with delivery executed across twelve offices in France (HQ plus Aix-en-Provence, Bordeaux, Lille, Nantes, Toulouse), Portugal (Lisbon, Porto), Romania (Bucharest, Cluj), Spain (Madrid), and Luxembourg. The customer base is anchored in French tier-one banking (BNP Paribas, Société Générale, Crédit Agricole, BPCE, HSBC, Credit Mutuel CIC, Natixis) and insurance (AG2R La Mondiale, Pacifica), with public sector contributing 25% of turnover, plus telecommunications, media, healthcare, and resources & services clients. Headcount exceeds 2,300 collaborators across five countries, and HN Institut (founded 1989) trains new and existing consultants on Java DevOps, Mainframe z/OS, and .NET stacks.

Go-to-market is enterprise-direct field sales targeting large accounts, with nearshore delivery hubs in Romania and Portugal enabling cost-optimized development and maintenance. Recent strategic activity includes two acquisitions completed in 2024, the establishment of the HN Digital Expertise pole (2022-2023) focused on Agile, DevOps, Cloud, and UX/UI quality, and ongoing geographic and product extension under CEO Antoine Hennache (appointed 2015). Two disclosed certifications — EcoVadis Gold and Qualiopi — support employer-brand and training-credibility positioning in regulated French enterprise procurement.
