What Arnecke Sibeth Siebold does
ARNECKE SIBETH DABELSTEIN (operating under the short name ASD) is a German full-service commercial law firm headquartered in Frankfurt am Main, operating as a Partnerschaftsgesellschaft mbB (partnership with limited professional liability). The firm was formed in 2021 through the merger of three mid-sized practices — Dabelstein & Passehl (Hamburg, founded 1930), Arnecke Siebold (Frankfurt, founded 1995), and Sibeth (Munich, founded 2005) — and now operates from six German offices (Frankfurt, Hamburg, Leer, Berlin, Munich, and Dresden) with more than 200 total staff including over 100 lawyers, notaries, and tax consultants. Its 20+ practice areas span Real Estate, Transportation/Aviation/Logistics, Maritime, Corporate/M&A, Banking & Finance, Digital Technology, Insurance, Energy, Labour, Antitrust, IP, Tax, Sports, Compliance, Commercial, Dispute Resolution, Media, Notary, Restructuring/Insolvency, and State Aid, with international market leadership claimed in real estate, transport, and maritime law. The firm also maintains a digital layer including the ASD Legal Information Hub, the ASD 42bit podcast, a partner-company legal tech subsidiary (ASD Digital Solutions GmbH) that produced the award-winning Digital Witness App, and integration with the Vispato whistleblower platform for EU Whistleblower Directive compliance.
The business model is a traditional professional services fee structure (hourly rates, fixed fees, and retainers — not publicly disclosed) delivered via partner-led enterprise engagement. Go-to-market is direct, supported by content marketing, an integrated website, industry events (e.g., EXPO REAL), and an extensive network of international professional associations including Interlaw and Legal Netlink Alliance for cross-border matters. Customers are corporate and institutional clients across regulated sectors, with named engagements including KWA Kuratorium Wohnen im Alter, HANNOVER LEASING, and Bayerische Hausbau Real Estate. The firm is independently owned by its partners, including Managing Partners Dr. Robert Šafran (Frankfurt) and Dr. Jan Tjarko Eichhorn (Hamburg), with no external parent or private equity ownership.
