About Nexis

World-class in Digital Identities, Roles, and Entitlements

Nexis delivers the leading Identity Visibility and Intelligence Platform (IVIP) that unifies identity-related data across IGA, PAM, and any kind of IAM system, spanning human and non-human identities and AI agent governance. The NEXIS Platform provides a unified view across the enterprise identity landscape for AI-driven analytics and real-time risk assessment, enabling automated remediation of identity security issues.

Unlike traditional IAM tools that require months of custom development, the NEXIS Platform's zero-code design enables deployment in weeks through 180+ pre-configured governance templates. Organizations gain actionable AI-powered insights, automated access governance, and simplified role and policy management without lengthy implementation cycles. Beyond IAM, integrated GRC capabilities support enterprise-wide risk assessment, policy management, and third-party governance. Built-in compliance support for GDPR, NIS2, and DORA ensures regulatory readiness from day one, reducing both complexity and operational costs.

The NEXIS Platform is trusted by 130+ customers worldwide, including leaders in finance, insurance, manufacturing, and automotive. Organizations in regulated industries choose NEXIS for unified identity visibility, intelligence, and automated governance.

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'm grounded in Identity Security – both academically and in practice – and I'm motivated by real, measurable outcomes. I work best where strategy meets execution – building teams, developing people, and helping clients make confident IAM and GRC decisions. I lead our sales and consulting organisation with a clear focus - turning security and reguatory requirements into practical solutions, creating trust, and driving sustainable growth. Behind the scenes, I keep the organisation aligned – connecting teams, sharpening priorities, and translating vision into momentum. I value ownership, continuous learning and strong long-term relationships – because in IT Security, lasting success is built on trust and consistency.

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.

Dr. 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.
