The relationship
Back in Stock is part of Amp.
Amp acquired Back in Stock in March 2025 to bring proven demand capture into a connected suite of Shopify growth products.
Back in Stock remains the focused product merchants know, with its own product site and Shopify listing. Inside Amp, it sits alongside Lifetimely and Amp's conversion products, connecting what customers want with the inventory, retention, and profitability decisions merchants make next.
