Situation
Carve sells premium outdoor and surf equipment. Mobile accounted for 68% of their traffic but only 42% of revenue — a 26-point gap that analytics traced directly to the theme. Load time on 4G averaged 8.2 seconds. The product page required 5 taps to reach the cart. We built them a custom Shopify theme from scratch.
