About
I turn complex products into compelling stories that drive adoption.
I'm Justin Witcoff, a product marketing manager based in Los Angeles with 7+ years of experience spanning AI, music, video, and consumer technology. Currently, I serve as the first and sole PMM at HeyGen, a Series A AI platform with $100M+ ARR, where I built the product marketing function from the ground up.
Before HeyGen, I spent nearly three years at Apple as a Product Marketing Manager across Shazam and Apple Music Radio, driving end-to-end go-to-market for concert discovery and flagship radio programming across four Apple surfaces.
I also founded Kodawari Labs, a consulting practice where I deployed AI products, growth experiments, and GTM strategy for early-stage companies across consumer, fintech, and entertainment. My approach blends deep user insight with technical fluency to build marketing that actually moves metrics.
