Leadership Team

Dr. Heiko Klarl, CEO

I am an Identity and Cybersecurity guy at heart. Making an impact is what drives and satisfies me. Building and growing companies and teams, mentoring individuals to succeed, and helping customers navigate the complexity of IAM are my strengths. I am solution-oriented, forward-thinking, always keeping a level head, and able to switch and adapt quickly. Openness, transparency, being present for the team, and building strong and long-lasting relationships and are key to me.

Dr. Michael Kunz, COO

I was able to deepen my passion for IAM in research at the University of Regensburg and at the same time had the opportunity to be one of the first employees to further develop the software technically and professionally over 10 years ago. In order to incorporate practical knowledge from customer projects into the platform, I was able to set up the Professional Services division and continue to support numerous customers in the implementation of IAM projects. The response to regular specialist presentations, the successful transfer of knowledge from practice to NEXIS 4 and the continuous development of our consulting team drive me to offer our consulting services at the highest level for our customers and partners.

Dr. Matthias Hummer, CTO

I’m passionate about redefining enterprise security as a catalyst for real business value. As CTO of Nexis, I focus on building secure, scalable, and user-centric systems that empower both organizations and individuals. My work blends technology strategy, product design, and deep expertise in Authorization Governance and GRC to turn regulatory complexity into opportunity. I believe great platforms don’t just meet compliance—they drive clarity, trust, and long-term impact.

Felix Gruber, CFO

My keen interest in finance and corporate development initially led me to study finance, controlling and business/tax law. There I laid the foundation for my professional career, which took me through various management positions in financial management. In these roles, I not only created structures and processes, but also actively supported and optimized strategic decisions. As CFO of Nexis, my focus is on securing the financial stability of the company and successfully developing it further with future-oriented strategies, in particular to enable long-term and sustainable growth.

Our Advisory Board

Daniel Zimmermann, Chairman

Developing companies a little further every day is what drives me. Having grown up in a family business, I have always been passionate about entrepreneurship. In addition to my long-standing role as Managing Director of a growing, medium-sized software product manufacturer, I have accompanied Nexis on its development path in recent years as Chairman of the Advisory Board. Sparring with the management team is a priority for me. For me, the highly motivated team, the ambition of each individual to develop further and the very market-oriented product are the basis for the successful growth of Nexis.

Ludwig Fuchs, Advisory Board Member & Strategic Advisor

As an enthusiastic IAM expert, I am always keen to close the gap between the functional requirements of the various business areas and the technical implementation by IT. My almost 20 years of experience as a lecturer and researcher at various universities and my practical project experience inspired me to develop the NEXIS 4 software, a tool for user-friendly and automated role and authorisation management. My high quality standards and my attention to detail are the key to the success of Nexis and our NEXIS 4 software.
