Why a 40% Gross Margin Can Turn Negative on Amazon ft. David Schomer

A 40% Amazon margin can shrink to almost nothing once the real costs start stacking up. In this episode of the Mad Growth podcast, Noah Wickham sits down with David Schomer, CEO of Build Grow Scale, to talk about the numbers behind profitability, smarter product choices, and lessons from launching nearly 3,000 SKUs. The conversation covers why some products fall apart after fees, why harder-to-ship products may be worth the trouble, and where AI fits into e-commerce in 2026.
