Chaos Appoints Iveta Cabajova as New CEO, Stephan Sieber Becomes Executive Chairman Amid Strategic Growth and AI Expansion

Chaos, a global leader in visual design software for the architectural, engineering, and construction (AEC) sector, has announced a leadership transition effective October 1, 2025. Iveta Cabajova has been promoted to Chief Executive Officer, succeeding Stephan Sieber, who will assume the role of Executive Chairman. The transition follows a well-structured succession plan and reflects Cabajova’s outstanding contributions since joining Chaos as Chief Operating Officer and Chief Financial Officer. Her leadership has been instrumental in driving growth, integrating key acquisitions such as EvolveLAB—a prominent AI software developer—and advancing the company’s strategic direction. With over 20 years of experience in the technology industry, Cabajova previously held senior executive roles at 1E and ITRS, where she led international expansion across EMEA and the United States through both organic growth and mergers and acquisitions. Her expertise in building scalable, operationally strong organizations makes her well-suited to lead Chaos into its next phase of innovation and expansion. In her new role, Cabajova expressed her enthusiasm and commitment: “I am honored to take on the CEO role at such a pivotal moment for Chaos. Building on the strong foundation established under Stephan’s leadership, we are well-positioned to shape the future of visual design software. My focus will be on strengthening our product portfolio, accelerating AI-powered visualization tools, and delivering exceptional value to our customers. I look forward to leading our talented global team and empowering architects, designers, and visual effects artists around the world.” Under Sieber’s tenure, Chaos has evolved significantly—from a group of specialized tools into integrated software suites that span the full AEC visual design workflow. The company has strengthened its leadership team, expanded its product offerings, and made notable advancements in AI, including the development of AI Enhancer and AI Material Generator, alongside strategic acquisitions. Sieber, now Executive Chairman, will continue to play a key role in shaping Chaos’ long-term strategy, overseeing major initiatives such as mergers and acquisitions, strategic partnerships, and board governance. He commented: “We’ve built a resilient, innovative company with a clear focus and a growing portfolio. Iveta’s vision, leadership, and deep understanding of our business make her the ideal leader to guide Chaos forward. I’m excited to support her and the executive team as we push the boundaries of what’s possible in visual design.” Investors TA and LEA, represented by Stefan Dandl and Christian Roth, praised Sieber’s transformative leadership and expressed strong confidence in Cabajova’s ability to ensure a seamless transition and continued success. They noted her proven track record and strategic insight as key assets for the company’s future.
