Matt Herzog
Head of Design @ LiveKit
I'm a designer and engineer. Currently designing and leading design at LiveKit where we're building the infrastructure and experiences for voice, video, and physical AI.
Previously at Medium, Mysten Labs, AKQA, and a few small startups.
I design and build AI products, with a focus on craft, clarity, and the details that make complex systems feel simple.
Projects
Demos
Voice AI demos spanning partner integrations, emerging technologies, and our own homepage — most designed and built in under 48 hours.
Craft
Interactions, animations, and tiny details I've built and shipped or experimented with over the years.
Writing
While I haven't written as much lately, for a number of years I'd write up design thinking and tutorials around designing and building products. Below are a few samples to get a sense of my writing and thought process.
