MARAIT is a European law firm and advises on all legal aspects of digitalization, in particular in connection with software projects, software licenses and data transfers in complex infrastructures. We focus in particular on advising on all legal issues relating to the licensing of SAP software and software from other manufacturers of enterprise software, as well as legal issues relating to the development, use and licensing of artificial intelligence. As part of our legal advice, we also cover the digital health sector, which is subject to numerous special regulations.

MARAIT was founded by lawyer and IT law specialist Dr. Jana Jentzsch in 2009, initially as a specialized IT legal consultancy, which was renamed Jentzsch IT Rechtsanwaltsgesellschaft mbH in 2015. Since April 2024, the company has been called MARAIT Rechtsanwaltsgesellschaft mbH and is based at Neuer Wall in Hamburg’s city center.

We see ourselves as consultants who not only analyze the formal legal requirements and look for the best concrete legal solutions, but also take into account the company’s IT strategy from a compliance perspective and, if desired, help shape it. The intensive involvement of the infrastructure, the respective technical functionality and the economic framework conditions is a matter of course.

As a law firm, we are bound by the law governing the legal profession. This not only imposes strict rules on confidentiality, but also on the performance and support of the mandate as an organ of the administration of justice. Lawyers are instruments of the rule of law by virtue of the qualifications conferred on them by law and help to enforce the rule of law, if necessary by representing clients in court. For this reason, only lawyers and, to a limited extent, tax consultants and auditors are allowed to offer legal advice in Germany. Normal GmbHs or other non-lawyer companies are prohibited from doing so.
