What Halys does

Halys is a French telecom software publisher founded in 2003 and headquartered in Issy-les-Moulineaux, France, operating as a Société par Actions Simplifiée (SAS) with 101–250 employees. The company develops and owns a complete portfolio of 4G/5G mobile core network platforms — including EPC for 4G LTE and 5GC for 5G Standalone — that are 3GPP and GSMA compliant and deployable on-premise, at the edge, or in the cloud. Its product suite comprises five core offerings: the 4G/5G Mobile Core (carrier-grade core for public, private, hybrid, and tactical networks), the Valise Tactique 4G/5G (a portable autonomous private network supporting up to 1 Gb/s and over 500 registered users), Mobile Roaming (SS7 Hub, Diameter Gateway, and GTP Hub for inter-operator signaling), Mobile Messaging (SMSC/MMSC with fraud protection), and a Licensed Operator platform (MNC 208-94) that gives Halys its own mobile operator status with 850+ global roaming interconnections.

The company primarily serves Mobile Network Operators (MNOs), MVNOs, carriers, and industrial/defense integrators across France, EMEA, and globally. Halys' named customers include Orange, Monaco Telecom, SNCF, Axione, Malitel, Comfone, Dauphin Telecom, and Alsatis, with platforms operating millions of connections daily across operator and private network environments. The business model combines platform licensing and deployment fees for core network software, recurring managed services with 24/7 support and SLA commitments, direct subscription revenue from its Licensed Operator connectivity services, and hardware sales/rentals for tactical network solutions. Sales are conducted through direct enterprise engagement and via telecom systems integrators and value-added resellers, with a published career listing indicating active commercial hiring in the French telecom software market.

Halys' competitive positioning centers on technological sovereignty — offering a complete, French-developed alternative to large foreign telecom equipment vendors — with particular emphasis on private 4G/5G deployments for industry 4.0, defense and security, events, and extended/coverage-critical sites. The company is led by a founder/management team (Samuel Dralet as Président, Marc Lovighi as Directeur Général, Benoît Mathian as CTO, Sébastien Cruaux as Directeur R&D, Julien Linden as Directeur des Opérations, and Crystele Trevisan as Directrice Marketing & Communication), with no disclosed external institutional investors or private equity ownership. The most recent strategic initiative is a February 2026 partnership with CIRPACK to deliver native Voice over New Radio (VoNR) capabilities in private 5G networks, extending the platform into manufacturing, healthcare, transport, and energy verticals.
