Entrepreneur since 1997


Years of experience as a lawyer

You can trust my entrepreneurial and professional experience!

Welcome to Lawyer Härtel

Browse through my website, including my 1100+ blog posts, and the explanations of my areas of law to get an idea of
me and my experiences.

As a lawyer and business consultant, I can assist you in all matters relating to the establishment, expansion and financing of your company throughout Germany and completely digitally, with a particular focus on IT law, SaaS, e-commerce, blockchain, computer games, e-sports and media, as well as contract drafting.

I combine my experience as an entrepreneur, many years as a contract lawyer and my extensive, also international, contacts.

I can be reached quickly and effectively via phone, email, Whatsapp, Discord or LinkedIn. Of course, the first contact costs nothing. Let's see if we fit together first!

Trustworthy advice

My advice is based on trust and fairness. My goal is to add value to the client when they hire me.


My dealings are always open and transparent. I inform about costs and risks as well as I inform about measures or advise against measures.


I have specialized in a few select areas of law and industries to provide my clients with effective and expeditious advice and handling.

KI - Help

Not only do I advise on AI legal issues, but I also provide an AI bot that offers legal questions and simply contract clauses from my area of law.


In addition to legal advice and business consulting, my clients also get free access to my network of other specialists.

Agile and modern

I have an agile and modern approach. A high level of communication and quick reactions are just as natural as a high level of digitalization in my office.

My services

fields of law and topics by Marian Härtel, attorney at law

I specialize in a few areas and also only accept commercial mandates.

Any questions?

If you have legal questions about your self-employment, just contact me

By contacting me through the chat, via e-mail or by phone, you will receive from me a non-binding 15-minute conversation. I consult nationwide and of course completely agile and digital. No one has to come by my office to get help.
