KARLSRUHE, Germany, Sep 9, 2025 – Chaos has announced the promotion of Iveta Cabajova to chief executive officer (CEO) effective October 1, 2025. Cabajova will succeed Stephan Sieber, who will transition to his previous role of executive chairman.
Chaos said the promotion to CEO is part of a succession process, accelerated by Iveta Cabajova’s performance as COO and CFO. She helped shape company strategy, drive growth and integrated acquisitions, including EvolveLAB. With more than 20 years in the technology sector, including leadership roles at 1E and ITRS, she brings experience in expanding businesses across EMEA and the United States through both organic growth and acquisitions.
Commenting on her new role, Cabajova said: “I am honored to step into the role of CEO at such an exciting time for Chaos. Building on the strong foundation established under Stephan’s leadership, we are in an excellent position to continue shaping the future of visual design software. My focus will be on leveraging our strengths, enhancing our product offerings, continuing to deliver best-in-class solutions for our customers and driving sustainable growth. In particular, we will accelerate our AI-powered visualization capabilities and further strengthen our position as the partner of choice for the world’s leading architecture and design firms. I look forward to leading our talented team and empowering our global community of architects, designers and visual effects artists.”
Under Sieber’s leadership, Chaos expanded its executive team and moved from standalone products to integrated suites built for the AEC visual design workflow.
Reflecting on the transition, Sieber said: “Over the years, we have built a highly resilient and innovative company, and I am very proud of the strategic strides we have made in focusing our efforts, expanding our product portfolio and advancing our AI capabilities through internal developments like the AI Enhancer and AI Material Generator, as well as the acquisition of EvolveLAB. Iveta’s exceptional leadership and strategic vision make her the perfect successor to lead the company into its next chapter of growth. I am excited to continue supporting Chaos’ strategic initiatives as Executive Chairman and look forward to supporting Iveta and the senior management team as we continue to push the boundaries of visual design and deliver groundbreaking solutions for our clients worldwide.”
Commenting on the transition, Stefan Dandl, director at TA, and Christian Roth, managing partner at LEA, added on behalf of the investors: “We are deeply appreciative of Stephan’s integral role in Chaos’ huge success under his leadership and look forward to continuing our partnership as he moves into his new role. Having known Iveta for many years, we are confident that her leadership, vision and experience will facilitate a seamless transition and continue to propel Chaos’ success.”
