I was an Amazon seller losing thousands to wasted PPC spend. I spent 20+ hours a week in spreadsheets. So I built Selzara. What it does: • Finds wasted PPC spend in 60 seconds (no API needed) • Tracks true profit across 72+ Amazon fee types • Predicts inventory stockouts before they happen • Optimizes listings for Rufus AI search $1 for 7-day trial. Then $39/month. Built by a seller, for sellers.
