Larcier Group

What Larcier Group does

Larcier-Intersentia, legally Lefebvre Belgium SA, is the Belgian operating subsidiary of the Lefebvre Group and a long-established publisher and digital solutions provider for legal, tax, and regulatory professionals. Founded in the 1840s, the company is headquartered in Louvain-la-Neuve, Belgium, with 270+ employees. It serves lawyers, accountants, tax advisors, notaries, magistrates, HR experts, companies, and public-sector/academic customers in Belgium, Luxembourg, and broader Europe.

The product portfolio is organized around three layers. First, AI-powered tools anchored by GenIA-L Assistant, a secure generative-AI tool designed for legal, tax, and business professionals that enables research acceleration, document comparison, and contract analysis against a validated knowledge base. Second, a family of searchable legal and tax databases — Strada lex Belgium, Strada lex Europe, Strada lex Luxembourg, TaxWin, and SocialWin — aggregating legislation, jurisprudence, and doctrine from official sources and 20+ publishing partners. Third, specialized professional utilities including First Annual Accounts (XBRL/PDF filing), Tax-IQ, Praxis, Sofisk, PCA-VOB, My Tips & Advice, and an Interest Calculator, targeting specific workflows in accounting, notarial practice, HR compliance, and tax optimization. A traditional publishing arm (books, codes, journals) and a professional training offering (5,300+ professionals trained annually) complement the digital stack.

Revenue is generated through four streams: recurring digital subscriptions (Strada lex, TaxWin, SocialWin, GenIA-L, etc.), one-time sales of books and publications, professional training and conferences, and advice-letter/expert advisory services. Pricing is quote-based and not publicly disclosed, with an annual billing cadence for subscriptions. The go-to-market combines a dedicated direct sales team with a self-service e-commerce webshop, supplemented by 80+ partnerships with professional associations, academic institutions (KU Leuven, UCLouvain, Paris 1/2, ESSEC, Solvay, Collège de l'Europe), and across Belgium, France, and Luxembourg. The company has 100,000+ users of its digital solutions per year and reports no external funding or M&A activity, operating as a wholly-owned subsidiary within the Lefebvre Group.
