"John rebuilt our Shopify store from scratch. Conversion jumped from 0.9% to 3.4% in the first 60 days and we finally feel like a premium brand online."
"Sigma understood our customer better than we did. The new product pages, bundles and email flows doubled our monthly revenue inside a quarter."
"We went from a clunky WooCommerce store to a high-converting machine. AOV is up 38% and returning customer rate is at an all-time high."
"The redesign on Squarespace was beautiful, but the real magic was the strategy. Sales tripled in the first holiday season after launch."
"John engineered an offer ladder and funnel that took our digital products from $1K to over $18K months. Strategic, fast, and ROI-obsessed."
"Most agencies hand you assets. Sigma hands you a growth system. ROAS doubled within two months and hasn't dropped since."
