HI, I’m Sean

I’m a dad and husband trying hard to raise a strong and confident little lady, be a great partner to my wife, cook great meals and build a great life.

Join my Friends Newsletter! Once a month I share a few things I find interesting, life highlights, at least one funny video or tweet and a playlist.

I run GSD Marketing, a B2B growth consultancy. In a world where marketers tend to desperately overcomplicate things we focus on keeping it simple and focused on driving repeatable revenue growth. And for 2026 I’m build a long-time passion project, Core Memories, turning years of my documenting my own family memories into a system and app for other parents.

Before going solo I founded and scaled a global strategy consulting team for Zeta Global. Over the course of my career in and around SaaA, agencies, startups and consulting, I’ve done a bunch of fun things. I got to lead the US GTM for Trumer Pils as a young AE in a boutique agency. I led marketing for a YC backed dating app and also ran a small DTC furniture brand during the height of the pandemic.

When I lived in SF I’d drive my old 240D up to Napa on weekends to pour wine and give tours at my all-time favorite winery. I’m still scheming on how to buy my own winery some day.

I’ve lived in Delaware, DC, SF, BsAs, NYC and back to good old Wilmington, Delaware.

You can find me online mostly at X and LinkedIn. Or Join My Friends Newsletter.
