What Aranzadi LA LEY does
Aranzadi LA LEY, S.A.U. is the leading Spanish legal technology and legal information provider and a wholly-owned subsidiary of Karnov Group (Nasdaq Stockholm: KAR). The company operates a 360-degree platform combining next-generation legal databases (Aranzadi LEY, Insignis, Digital, LA LEY Digital), predictive judicial analytics via Jurimetría, an AI-powered research and drafting assistant (Allegra), case management software (Aranzadi Fusión for law firms, corporates, institutions, and procuradores), a modular compliance suite (Complylaw with Penal, Canal Ético, Privacidad, Igualdad, Fiscal, Operaciones Vinculadas modules), document automation (ContractBOX), and a digital library (Legalteca). The proprietary content corpus is built on the contributions of 6,500+ authors and collaborators, and the platform is differentiated by Spanish National Security Framework (ENS Alta and Media) and ISO 9001/14001 certifications that enable public-administration and regulated-enterprise deployment.
The company serves 23,000+ clients including international law firms (Hogan Lovells, Roca Junyent, Ontier, Addleshaw Goddard), large corporates (Iberdrola, Heineken, MásMóvil, Banc Sabadell), professional services firms (Auren), public bodies (ICAB, Consejo General del Notariado), and SMEs. Revenue is generated through recurring subscriptions to databases and SaaS products (Aranzadi Fusión, Complylaw), one-time publication sales, and professional services, with pricing delivered via quote-based annual or multi-year contracts. Distribution follows a hybrid model: dedicated direct sales for enterprise and institutional clients, an online store (Tienda) for self-service, an inside-sales customer service center (CAC), and partnership channels with professional associations. The company employs 500+ staff across offices in Madrid (headquarters) and Las Rozas.
As the Spanish vehicle of the publicly listed Karnov Group, Aranzadi LA LEY benefits from integration into a European legal information platform serving 400,000+ users and 7,000+ specialists across multiple jurisdictions. Recent strategic emphasis has been on generative AI (Allegra launch in 2024), predictive analytics, regulatory-grade compliance tooling (ENS certifications for Aranzadi Fusión SaaS and Complylaw Canal Ético in 2025), and an Advisory Council of 21 senior Spanish legal figures that anchors editorial credibility.
