I am an IT lawyer and business consultant who specializes in online entertainment, web media and computer games. My clients and clients mostly come from Europe, the USA or Asia and mainly develop computer games or other online entertainment platforms, earn money in the esports industry or publish content on computer games and IT on the platforms. YouTube and Twitch or other social media platforms.

I am also an entrepreneur and consultant for the IT industry with many years of experience in building and leading teams, in-depth IT knowledge and creative ideas for optimizing business structures as well as the necessary sense for future trends. I have led leading companies in the licensing and marketing of online games and mobile games, and have experienced in overseeing activities in the Asian gaming market and an expert in emerging markets.

Due to my extensive contact base, my experience in international markets, the leadership, improvement and the development of teams and my personal interest in IT topics, I have extensive knowledge in the field of business development of IT-based companies. I therefore support media companies and media startups in the creation of legal texts and contract creation.

In addition, I specialize in the field of esports and advise companies in the construction and market entry into the booming market of esports. I also develop sponsorship agreements for players and teams, as well as player contracts. I can map the current special features of the questions of social security and professionalization in esports.

Finally, I also advise YouTubers and Twitch streamers on marketing, professionalization, branding, business start-up, and liability issues.

My experience in the fields of copyright law, competition law and other IT law includes legal proceedings and expert opinions for all instances, including activities as a correspondent in BGH proceedings and proceedings at the Federal Constitutional Court.


For me, comprehensive support for my clients is important. I accompany clients from the concept phase of a company start-up or the pitching of a project, through the realization and implementation. Long-term and trusting cooperation is of great importance to me.


I completed my studies at the FU-Berlin from 1997 to 2004. Influenced by my stay at a high school in the USA, I was particularly enthusiastic about the international aspects. Since 1998, I have also been working as an entrepreneur myself and, while still studying, I set up a company with more than 30 employees. After completing my studies, I was able to professionalize the company and eventually sell it to investors. The company is now part of Gamigo AG.

During my legal clerkship at the Kammergericht in Berlin, I was able to gain valuable experience and worked for the then co-founder of the GAME Bundesverband, Malte Behrmann. During my legal clerkship, I helped Chili Entertainment GmbH found the ad network Ad2games. With Malte Behrmann I founded my first own law firm Behrmann & Härtel in order to earn my first spurs. In addition, I founded H&H Games Consulting GmbH and operated the German representative office of the largest advertising network for computer games, called CPMStar, for the US group GSN.

In 2012, I founded OnLegends GmbH with industry veteran Julian Migura and Malte Behrmann, which specialized in the transfer of computer game licenses from Asia to Europe and South America. The activities for OnLegends GmbH and H&H Games Consulting GmbH meant that I was able to build up a great wealth of experience in Asian markets, especially China and Korea, as well as a large network. Finally, in 2017, I founded Esports Consulting GmbH, with which I advise companies entering the market and setting up esports activities.
