An Agency Built by Someone Who's Actually Done It

Endless Wave Marketing was founded in 2017 by Ed Szoc — not a career agency person, but an operator who has spent over a decade and a half in the trenches managing ecommerce P&Ls, running Amazon ad accounts, and building DTC programs from scratch.

Ed Szoc — Founder & Lead Strategist

MBA, Rutgers Business School  |  15+ Years Ecommerce & Amazon Management

Ed is one of the most experienced hands-on Amazon and DTC practitioners in the industry. He manages accounts directly, runs campaigns himself, and brings the same rigor to client work that he applies to the brands he owns and operates.

Track record:

• Baby Brezza / Baby Boom (9 years): 36% Amazon CAGR, 118% DTC website CAGR over 5 years, doubled the site’s conversion rate, grew loyalty rewards program from zero to 500,000+ members
• Pool Table Squad: Complete business turnaround — 76% revenue increase, 400% organic search growth, 67% reduction in Google Ads cost per lead — achieved within 2 years

Ed’s hands-on expertise spans the full ecommerce stack: Amazon AMS, AMC, DSP, and Vendor Agreements; Shopify; Google, Meta, and Bing advertising; Walmart Connect; Criteo; email and SMS marketing; and conversion optimization.
