Leadership Edge: TRXL 184
A conversation with Stephan Sieber and Bill Allen about exploring the merger between Chaos and EvolveLab, leveraging AI tools for enhanced design processes, and emphasizing the need for architects to adapt to rapidly changing technology to stay relevant in the industry.

Summary
In episode 184, I sat down with Stephan Sieber, CEO of Chaos, and Bill Allen, former CEO of EvolveLab and now Director of Products at Chaos, to talk about their merger and how what they’ve done could also mean for the future of AEC tech. This wasn’t just a conversation about M&A strategy. It was a front-row seat to how two innovation-focused teams are coming together to reshape design workflows, elevate practitioner agency, and accelerate the integration of AI across the AEC toolchain. From tools like Veras and Envision to the cultural synergies driving their partnership, this episode is a powerful case study on what’s possible when vision and execution collide.
“We want to close the loop from ideation all the way to construction documentation—and we want to do it without requiring a PhD to operate the software.”
— Stephan Sieber
