HELLRIEGEL RECHTSANWÄLTE

What HELLRIEGEL RECHTSANWÄLTE does

HELLRIEGEL RECHTSANWÄLTE is a Berlin-based boutique law firm specializing in public economic law (öffentliches Wirtschaftsrecht), founded in 2020 by Managing Partner Prof. Dr. Mathias Hellriegel LL.M. The firm operates from a single office at Schlüterstraße 54 in Berlin-Charlottenburg and fields a team of seven lawyers (twelve total employees including administrative staff) plus two supporting staff. Its mandate covers construction and infrastructure projects across their full lifecycle — examination, planning, financing, implementation, and defence — with deep specialization in building permit procedures (Bebauungsplan- und Baugenehmigungsverfahren), redevelopment and conservation law, monument protection, planning approval and railway law (Eisenbahnrecht / Planfeststellungsrecht), environmental, nature conservation and contaminated sites law, public budget and subsidy law, and constitutional and administrative law.

The firm serves enterprise and government clients: international and domestic investors and project developers, banks financing construction and infrastructure transactions, and public sector institutions (Öffentliche Hand) including government agencies. Its GTM motion is partner-led, project-based engagement anchored in Prof. Hellriegel's honorary professorship at TU Berlin and lecturing at IREBS Real Estate Academy, plus an extensive publication record in BauR, NVwZ, Immobilien Zeitung, and Frankfurter Allgemeine Zeitung. Consecutive recognition in JUVE Handbuch Wirtschaftskanzleien (described as 'one of the undisputed top dogs in Berlin for urban development projects'), Handelsblatt Best Lawyers, and WirtschaftsWoche TOP Kanzlei rankings functions as the primary third-party quality signal for client selection.

Revenue is generated exclusively through professional services fees for legal advisory, billed under quote-based engagement structures negotiated per-matter depending on scope and complexity. The firm does not develop or sell technology products — its 'core technology' field is explicitly 'Not applicable'. There are no patents, software products, app store presence, or API offerings. The firm has no external institutional investors, no parent company, and operates as a privately held partnership (sole proprietorship under the Managing Partner with co-founding Partner and Counsel).
