About Marcus Cai

I studied psychology and got into design through music production and the web, building and tinkering with websites in the early days.
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 building with AI tools like Claude and Codex, which has closed the gap between having an idea and quickly prototyping to validate it.
I still make music when I can, and outside of work, I'm with my family, whether we're out exploring or just taking it slow.
