Composer 0→1: Design that Delievered

At Matterport, I’m leading design for Composer, our first new product surface in five years and a 3D design tool for architects, engineers, and builders. In less than 6 months, our team took it from sketches on a whiteboard to a revenue-generating product that has expanded our sales opportunities and addressed years of customer requests.

Matterport’s $1.6 billion acquisition by CoStar Group in 2025 signaled strong confidence in the role of B2B products like Composer in shaping the company’s next chapter.

From 10,000 ft to Ground Level

I worked at many altitudes on Composer, defining the product strategy, designing the system architecture with engineering, creating end-to-end user flows, building a new design system, prototyping key interactions, and crafting all of the final UI.

Raising The Bar for Craft

Directed and built a new design system that evolved the brand and gave teams the tools to ship faster and more consistently.

Full Team Research

Involved engineers, PMs, and partners in interviews, research question development, and usability sessions so everyone shared the same view of user problems. Directly led to faster feature development and papercut fixes.

Created Clarity

Design has been a central method at the heart of everything we’ve built with Composer—and continues to be! From early discovery and definition to full end-to-end UX to the refinement of interaction and early prototyping, design helped usher this new product surface to light.
