About Marcus Cai

I studied psychology and got into design through music and the web, building websites and blogs before I really knew that counted as design.

Over the past decade, I've built products that connect people: helping players find the right experiences through search at Roblox, bringing businesses closer to their customers through messaging at Meta, and at Oculus, making virtual reality more social and giving its developers better tools to build with. Now I'm at Zillow working on new construction, helping buyers find their way into the home they've been dreaming about.

The domains that pull me in tend to be challenging or overlooked. My range of experiences rarely share an orbit, but they end up shaping each other. Lately I've been prototyping with AI tools like Claude and Codex, which has closed the gap between having an idea and being able to tinker and play with it.

I still make music when I can, mostly as an excuse to keep buying samplers and synths I don't need. The rest of my time goes to my wife, two kids, and my dog, whether we're off exploring somewhere new or just taking it slow at home.
