Gustavo Rivero

Founder & Developer

Based in Orlando, Florida. I run American Store US — we sell LEGO, NECA, McFarlane and other authorized brands across Amazon, Walmart, Shopify, eBay, TikTok Shop and Whatnot. I built every tool in ASUSAPP because nothing on the market did what I needed.

When you're juggling thousands of orders across six channels and fighting for the Buy Box every day, generic software doesn't cut it. So I wrote my own.

"There's no single platform that handles inventory, repricing, sourcing, and shipments across six channels. So I built one. It changed how I run my business — and I'm making it available so it can change yours too."
