I am Marian Härtel


I am an experienced IT lawyer and business consultant focusing on the dynamic areas of online entertainment, web media and computer games. My expert knowledge spans innovative IT topics such as media, SaaS, AI and streaming providers. I represent and support companies and vendors in the gaming, esports, and influencer industries by drafting contracts specifically tailored to them and providing advice on funding and scaling.

My clients are internationally active and come mainly from Europe, the USA and Asia. They are involved in the development of computer games and online entertainment platforms, generate income in the booming esports industry or publish content on computer games and IT on platforms such as YouTube, Twitch and other social media channels.

In addition to my legal work, I also bring extensive entrepreneurial experience and consulting expertise in the IT industry. With my in-depth IT knowledge, my creative approach to optimizing business structures and my intuition for future trends, I have supported leading companies in the licensing and marketing of online and mobile games. My expertise also extends to the Asian gaming market, and I am known as a recognized expert in emerging markets.

Thanks to my broad network, my international market knowledge, my leadership skills and my passion for IT topics, I have extensive experience in the business development of IT-based companies. I use this expertise to help media companies and start-ups draft legal documents and contracts.

A special focus of my work is in the area of e-sports. I advise companies on setting up and entering the rapidly growing e-sports market. In addition, I draft sponsorship agreements for players and teams as well as player contracts, always taking into account the current specifics regarding social security issues and professionalization in esports.

Additionally, I advise YouTubers and Twitch streamers on marketing, professionalization, branding, business formation and liability.

My extensive experience in copyright, competition and other IT law includes litigation and expert opinions in all instances. As a correspondent attorney, I have acted in proceedings before the Federal Supreme Court and the Federal Constitutional Court, which underscores my expertise and commitment in this area.



25 years experience

As an entrepreneur

The holistic support of my clients is at the center of my work as an IT lawyer and business consultant. I accompany my clients through all phases of their business development – from the initial conception and pitch of a project, to its realization and completion. I attach great importance to a long-term, trusting cooperation.

Education and professional career

My academic career began in 1997 at the renowned Free University of Berlin, where I studied until 2004. Inspired by a high school stay in the USA, I developed a special interest in international aspects of law during my studies. Parallel to my studies, I had already been working as an entrepreneur since 1998 and built up a company with over 30 employees. After graduating, I was able to further professionalize the company and eventually sell it to investors. Today the company is part of Gamigo AG.

During my legal clerkship at the Berlin Court of Appeal, I gained valuable experience and worked for Malte Behrmann, the then co-founder of the GAME Federal Association, among others. During this time, I supported Chili Entertainment GmbH in founding the Ad2games advertising network. After my legal clerkship, I founded my first own law firm, Behrmann & Härtel, together with Malte Behrmann, and earned my first spurs there. At the same time, I founded H&H Games Consulting GmbH and managed the German representation of the largest advertising network for computer games, CPMStar, for the US corporation GSN.

In 2012, together with industry veteran Julian Migura and Malte Behrmann, I founded OnLegends GmbH, a company specializing in brokering computer game licenses from Asia to Europe and South America. Through my work for OnLegends GmbH and H&H Games Consulting GmbH I was able to gain extensive experience in the Asian markets, especially in China and Korea, and build up a wide network. In 2017, I finally founded Esports Consulting GmbH, with which I advise companies on their market entry and the development of esports activities.
