Elium is a European knowledge management software platform delivered as Software as a Service (SaaS) for enterprises. Founded in 2007 and originally named Knowledge Plaza, the company rebranded as Elium in March 2017.[1] Its headquarters are in Louvain-la-Neuve, Belgium.
The platform provides a knowledge infrastructure designed to capture, structure and maintain enterprise knowledge, serving both end users and AI agents. It supports use cases including company-wide knowledge bases, customer service, IT technical support, market intelligence, employee onboarding, wikis and knowledge sharing across distributed teams. Customers include BCG, BNP Paribas, Bouygues, Council of Europe, Fnac Darty, L’Oréal, SNCF and VINCI Energies.
In the 2026 edition of the annual benchmark carried out by French consultancy firm Lecko[2], which evaluates 20 digital workplace platforms across 36 use cases and six functional families, Elium is described as a “reference European SaaS provider for enterprise knowledge management”[3]. Lecko highlights its “knowledge-as-code” approach, treating enterprise knowledge as a versioned and governed asset, and its increased adoption as a “source of truth” for corporate AI services.
In September 2013, the company announced the acquisition of Swiss social publishing company Hyperweek.[4] In August 2017, Elium closed a Series A funding round of €4 million led by Serena Capital in collaboration with S.R.I.W.[5] In May 2022, the company obtained ISO/IEC 27001 certification for information security management.[6]
