Tsambikakis & Partner Rechtsanwälte mbB

What Tsambikakis & Partner Rechtsanwälte mbB does

Tsambikakis & Partner Rechtsanwälte mbB is a Cologne-headquartered German boutique law firm founded in 2015 by Prof. Dr. Michael Tsambikakis, specializing exclusively in commercial (white-collar) criminal law — including commercial, medical, tax, IT, corruption, capital-market, and insolvency criminal law — and serving companies, executives, healthcare organizations, financial institutions, and government bodies. The firm operates from four German offices (Cologne HQ, Frankfurt, Berlin, Hamburg) with roughly 14 listed legal professionals: five practicing partners (Tsambikakis, Mückenberger, Nadeborn, Kessler, Gierok) supported by three university professors serving as Of-Counsel or scientific advisors (Saliger at LMU Munich, Kubiciel at Augsburg, Gaede at Bucerius Hamburg), plus associates and counsel. The practice blends preventive compliance, internal investigations, crisis management, dawn-raid support, witness assistance, and full criminal defense before all German courts and authorities.

The product surface extends beyond traditional legal services to include three proprietary digital offerings: the Tsambikakis mobile app (iOS/Android) for 24/7 emergency legal contact during searches and arrests; the Tsambikakis Whistleblower System, a web-based anonymous reporting portal enabling HinSchG compliance for companies with 50+ employees; and Compliance EasyCheck, a one-day healthcare-focused compliance risk assessment. Adjacent modules include External Compliance Officer, Internal Investigations, Krisenmeister Cyberangriffe (delivered jointly with cooperation partner Bernstein Group for ransomware response), Helpdesk subscriptions, Lectures & Trainings, and Legal Expert Opinions.

The business model is a professional-services partnership (Partnerschaftsgesellschaft mbB) with no external investors or parent. Court-mandated work is billed under the German statutory fee schedule (RVG); advisory, compliance, and productized services are billed on a negotiated basis. Customer acquisition runs almost entirely through reputational channels — sustained top-tier placement in Handelsblatt/Best Lawyers, Legal 500, JUVE Handbuch, WirtschaftsWoche, FOCUS, Capital, brand eins, Leaders League, and Who's Who Legal — combined with peer referrals and the firm's academic authority, rather than any self-serve or product-led motion.
