What Larcier-Intersentia does
Larcier-Intersentia is the Belgian operating subsidiary of Lefebvre Group (legal entity Lefebvre Belgium SA), providing subscription-based digital databases, software, and AI-powered research tools for legal, tax, accounting and HR professionals. Headquartered in Louvain-la-Neuve with offices in Berchem, Gent and Windhof (Luxembourg), the firm employs 270+ people and traces its publishing lineage to 1839 (Bruylant predecessor), operating brands such as Larcier, Intersentia, Strada lex, TaxWin, SocialWin, My Tips & Advice, Sofisk and Tax-IQ.
The technology stack centres on the Strada lex database family (Belgium, Europe, and Luxembourg editions) that aggregates legislation, jurisprudence and doctrine from official sources and 20 publishing partners, surrounded by a portfolio of more than 13 specialised products. In July 2025 the firm layered a generative-AI capability on top via GenIA-L Assistant, a secure tool for research acceleration, document comparison, contract analysis and information verification, validated by the firm's 1,500+-author knowledge base. Adjacent offerings include Sofisk (cloud post-accounting), First Annual Accounts (XBRL/PDF filing), Praxis, PCA-VOB, the Interest Calculator and Tax-IQ. Distribution combines an e-commerce webshop, a dedicated sales team for enterprise and regulated professionals, professional association channels (AVOCATS.BE, Fednot, ITAA, Chambre nationale des notaires) and academic partnerships with KU Leuven, UCLouvain, ULiège and Paris 1 Panthéon-Sorbonne.
The business model is hybrid: recurring subscription revenue from digital platforms (Strada lex, TaxWin, SocialWin, GenIA-L, My Tips & Advice, advice letters), one-time/perpetual-license sales of physical books and codes (€56–€203 per title), and unit-priced training including webinars and in-house programmes. GTM is sales-led with product-led self-serve on the webshop, targeting legal professionals and tax/accounting professionals as primary segments, plus companies/self-employed, public sector, academia and HR experts as secondary segments. The firm serves more than 100,000 digital users annually, trains 5,300+ professionals a year and was recently recognised with the Prix du Cercle Montesquieu 2024.
