About
Executive eCommerce expertise, on your side
MarketplaceMax pairs consultancy-grade strategy with hands-on execution — led by a founder with 20+ years scaling brands across Shopify, Amazon, and Walmart.
Why we exist
Growing an eCommerce business means making the right calls across strategy, marketplaces, DTC, and operations — and most brands end up juggling five vendors to do it. For international brands, add the hurdle of entering a foreign market entirely. We built MarketplaceMax to be the alternative: one accountable team that owns the whole go-to-market — whether you're scaling in the U.S. or entering it for the first time.
How we work
Strategy first, then execution. We pressure-test the opportunity, build the plan, and then run it — marketplaces, DTC, operations, and growth — as your outsourced team. Led by founder Howard Wyner, an eCommerce growth leader with 20+ years across Shopify Plus, Amazon, Walmart, and eBay who has built omnichannel programs directly with retailers like Walmart and Home Depot, we've seen what works and what quietly breaks a launch.
