Zack Brenner is Marketing at OpenSea.

I’m a builder and operator who enjoys taking businesses from 0 → scale.

At Rally, I helped grow the platform from an idea into a community-driven trading ecosystem with millions in transaction volume and 100k+ users. This work led to Rally’s acquisition by OpenSea in 2025, where I now lead its token trading business.

Throughout my career, I’ve focused on driving business outcomes through creative go-to-market strategies, community-led growth loops, and high-leverage partnerships across ecosystems.
