David Gallo has spent 12+ years as an Amazon seller and operator — first as founder of Worldfront, an Amazon account management firm that grew to 57 active seller accounts and $350M+ in combined sales managed, and then as a private label brand builder under Tribesman LLC. He built SellerForge because no existing tool gave him what he actually needed: AI that knew his accounts, understood Amazon's enforcement patterns, and could replace the expensive agency infrastructure he'd spent years managing. The platform is what he wished he'd had on day one. Every feature is drawn directly from real operational pain across hundreds of ASINs, thousands of campaigns, and dozens of reinstatement cases.
