Jae Jun

Jae Jun is the founder of Gorilla ROI and a multi-million dollar Amazon seller since 2013. Born in Korea, raised in Australia, and based in the Dallas area, he started selling on Amazon to liquidate dead inventory and built a 7-figure brand from it. When manual reporting started costing the business 20–30 hours a week, he built Gorilla ROI: a Google Sheets data connector that automatically syncs Amazon, Shopify, and Walmart data without csv exports or broken formulas. The tool now has 11,000+ downloads and a 4.8 rating on the Google Workspace Marketplace, used by ecommerce teams averaging $3M a year in Amazon sales.
