Phoenix is a popup app for Shopify, powered by AI. It reads shopper intent in real time and only triggers an offer when it'll actually save the sale. Most popup apps bleed margin on customers who were already buying — Phoenix doesn't. It runs silently in Shadow Mode before touching a single shopper, A/B tests copy in your brand voice, and scales on a dial you control — 0% to 100%.
