What Arendt & Medernach does

Arendt & Medernach is an independent Luxembourg-headquartered business law firm founded in 1988, employing 1,340 professionals across six international offices (Luxembourg, Hong Kong, London, New York, Paris, Frankfurt). It serves international asset managers, banks, insurers, corporations, and private clients with three integrated service pillars: Legal & Tax (covering corporate/M&A, banking & finance, investment management, insurance, tax, litigation, employment, IP/tech, EU financial & competition law, restructuring, and private clients), Regulatory & Consulting (regulatory compliance, AML/CFT, cross-border distribution, business and tech transformation, forensic investigations, and managed services), and Investor Services (corporate services, fund administration, governance, depositary, tax compliance, and third-party AIFM via subsidiary AManco).

The firm monetizes through four billing models — time-spent at hourly rates, fixed recurring fees, minimum annual fees, and annual responsibility fees for board and entity mandates — alongside Arendt Institute training programs and the Arendt Play digital knowledge platform launched in May 2026. Underlying delivery rests on a partner-led, enterprise go-to-motion backed by an ISO 27001-certified technology layer, a multi-factor client portal, and a portfolio of AI-assisted legal research, document drafting, board-meeting transcription, and prospectus-compliance tools. Distribution is direct through the office network and the Arendt Investor Services platform, augmented by a content and events-led marketing apparatus; the Benelux Law Firm of the Year 2022 award and consecutive Chambers, Legal500, IFLR1000, and ITR rankings underwrite brand-led demand.

Strategically, Arendt has executed a multi-year international build-out (Paris 2016, Frankfurt 2024, refreshed New York leadership 2023), broadened the non-legal services franchise (Arendt Services rebranded as Arendt Investor Services in March 2024), nine partner promotions across 2024-2026, and a 2025 CIO appointment to consolidate technology and AI operations. In July 2026, BlackFin Capital Partners acquired a majority stake in Arendt Investor Services with CSSF approval, leaving Arendt & Medernach as a significant minority shareholder and providing AIS with capital for cross-border M&A and AI investment while Arendt & Medernach continues to operate independently as the lead legal advisor.
