MISMO Informatique S.A.S.

What MISMO Informatique S.A.S. does

MISMO Informatique S.A.S. is a privately held, family-owned French IT services and software company founded in 1992 and headquartered in La Chapelle-sur-Erdre near Nantes. It serves roughly 1,200 active clients — primarily small and medium enterprises (PME) and mid-size firms (ETI) across metropolitan France — with a stated €14M of annual turnover and approximately 100 employees distributed across six regional agencies along the Atlantic coast (Nantes, Toulouse/Labège, Laval, Angers, Brest, La Roche-sur-Yon, Rennes). Alexandre LEBRETON serves as Gérant and Directeur Général Délégué, and the company operates as a single legal entity (SIREN 388 185 068) with no disclosed parent or external institutional ownership.

The company's offering is dual-pronged. On the software side, it develops and markets the proprietary Athénéo suite — including Athénéo ERP, CRM, SAV (after-sales service), RH (HR information system), Mobitech (mobile field access), and GCSP (commercial management) — sold via one-time licenses (DEL/DUA) or monthly SaaS rental (Loyer). On the services side, Mismo Active Protection provides recurring managed IT services (maintenance, supervision, cloud hosting, cybersecurity), hardware procurement, and professional consulting/implementation. Revenue is generated through a mix of subscription managed-services contracts, software licenses, hardware resale, and fixed-fee or time-and-materials professional services, with partnerships spanning Pennylane, Sage 100, Silae, Microsoft 365, Effisocial, and various hardware/security vendors.

Distribution is direct and field-led: a sales team operates from HQ and regional agencies with dedicated business development for ERP, supported by content marketing, an annual Mismo Days event series (~500 attendees), and active LinkedIn presence. The customer base is diversified across industries including water treatment, healthcare, insurance, manufacturing, construction, food, and public-sector/non-profit segments, with named logos such as Culligan, Hemodia, Bioliance, Mutuelles de Bretagne, Funecap, and Chanteclair. Certifications (AFAQ, ITIL, Planet'RSE) and a Syntec Top 250 software publisher ranking (126th in 2020) provide third-party validation, and a recent 2025 strategic partnership with Pennylane signals continued investment in cloud-finance integration.
