MATT EPSTEIN
Hi, I'm Matt
I’ve spent my career building growth engines — from launching Prime Day at Amazon, to growing SiriusXM’s streaming business from scratch, to leading Walmart+ loyalty and retention.
​
Today, as Partner and Growth/GTM lead for LF Partners, I advise companies across retail, media, fitness, travel, and fintech. I help them build systems that turn customers into members, and members into long-term value.
My book, Mastering Membership, is the strategic playbook I wish I had earlier — packed with real frameworks, tools, and tactics for sustainable growth.
