What Decalog does
Decalog S.A.S. is a French software publisher founded in 1995 and headquartered in Guilherand-Granges (Ardèche), operating as a wholly-owned subsidiary of the diversified group Groupe Yoni. The company specializes in 100% SaaS library management solutions (Système Intégré de Gestion de Bibliothèque, or SIGB) for public libraries, inter-municipal reading networks, employee cultural committees (CSE), and public digital spaces (EPN) in France, claiming 2,300+ equipped sites, 10,000+ professional users, and 3.6 million subscribers across 37 countries.
The product suite is modular and cloud-native: Decalog SIGB is the core collection-management platform handling cataloging, circulation, patron management, and acquisitions; Decalog Portail/Portail Pro is a self-service web portal builder for public-facing library sites; Decalog EPN secures public workstations, tablets, and WiFi; and DecaPocket/BibEnPoche provides mobile patron access. Supporting modules include Decalab (a client co-development community platform) and DecaScore (a deep-learning-based acquisition recommendation service that won recognition in the French Ministry of Culture's 2020 Innovative Digital Services call). The platform is SIP2-compatible for third-party hardware integration, hosts primary production at NEXEREN (Groupe XEFI) ISO 27001-certified data centers, and maintains disaster recovery at OVH sites in Roubaix and Strasbourg with redeployment in under 48 hours. Hardware (loan automation terminals at €3,300–€4,900 HT) is sold direct as a complement to subscriptions.
The business model is anchored in recurring SaaS subscriptions billed annually or multi-year, with no public pricing and no third-party resellers — distribution is direct field sales to municipal and CSE buyers, supported by account managers, the ABF congress presence, and a Qualiopi-certified training organization. Additional revenue comes from professional services (data migration, consulting, hosting) and hardware sales. Decalog is privately held, employs 11–50 people, and transitioned leadership from Michel Ziegler to Alexandre Mamy in February 2025.

Decalog competitors and assessment
Company assessmentBroad incumbents
- OCLC (WorldShare): OCLC is a global library cooperative offering the WorldShare Management Services platform alongside shared cataloging, ILL, and discovery services. It is the dominant library network globally and a broad incumbent that competes in library software and data services across the public, academic, and research segments.
- SirsiDynix: SirsiDynix provides the Symphony and BLUEcloud library management platforms used across public, academic, and school libraries worldwide. It serves the same functional categories as Decalog SIGB (cataloging, circulation, patron management) at a much larger scale, primarily in North America and the UK.
- Innovative (Polaris / Sierra): Innovative, now part of Clarivate alongside Ex Libris, provides Polaris and Sierra library management platforms serving public and consortia libraries. It is one of the largest commercial LMS vendors globally and competes broadly with Decalog on integrated library management functionality.
- Ex Libris (Alma): Ex Libris, part of Clarivate, provides the Alma library services platform primarily serving academic and research libraries worldwide. While not focused on French public libraries, it represents a global incumbent that could enter Decalog's territory and a reference benchmark for enterprise-scale LMS functionality.
Regional players
- Biblionet: Biblionet is a French regional operator offering library network services, hosting, and consulting to public library networks, primarily in southern France. It overlaps with Decalog on managed library services and infrastructure support for the same target customers, though not as a direct SIGB competitor.
Direct peers
- GB Concept (Orphée): GB Concept is the developer of Orphée, one of the leading SIGB (Systèmes Intégrés de Gestion de Bibliothèque) solutions used by French public libraries. Like Decalog, it serves municipal and inter-municipal library networks in France with integrated cataloging, circulation, and patron management functionality, making it the closest direct domestic competitor.
- Koha: Koha is the most widely adopted open-source integrated library system globally, with significant deployment in French libraries via service providers like PTFS Europe. It offers comparable cataloging, circulation, and patron management features to Decalog SIGB and is the primary open-source alternative for resource-constrained libraries.
- PMB Services: PMB is a France-rooted open-source library management system widely deployed in French public libraries, with hosted and supported offerings. It competes with Decalog on the same core SIGB functionality and is a key alternative for budget-conscious municipalities that evaluate Decalog.
Others
- Bibliothèque nationale de France (BnF): The BnF provides national infrastructure and shared services for French libraries, including bibliographic data (via Distrimage) and shared cataloging standards. While not a competitor, the BnF is an ecosystem participant whose services integrate with Decalog SIGB and shape the standards Decalog must support.
Emerging players
- Equinox Software (Evergreen): Equinox Software supports the Evergreen open-source integrated library system used by consortium-scale public library systems, particularly in North America. It represents a smaller, niche open-source competitor with overlapping functionality and partial overlap with Decalog's target market.
