About Rebuy Engine
Rebuy Engine is a personalization and merchandising platform built for Shopify and Shopify Plus merchants, founded in 2017 and headquartered in Scottsdale, Arizona. The company was co-founded by John Erck, who serves as CEO, with a focus on enabling online retailers to increase revenue per visitor through automated product recommendations and targeted offers.
Rebuy's platform integrates directly into Shopify storefronts and provides tools including smart cart functionality, post-purchase upsell pages, checkout upsells, product recommendation widgets, and re-order landing pages. The platform uses rules-based and machine learning-driven logic to surface relevant products at various points in the customer journey. It is used primarily by direct-to-consumer brands operating on Shopify.
Rebuy has operated without disclosed external venture funding and has grown through the Shopify app ecosystem, where it maintains a presence on the Shopify App Store. The company has expanded its team to the 51–200 employee range as of recent years and has positioned itself within the broader Shopify partner ecosystem alongside complementary tools in email, loyalty, and subscription commerce.

Competitive Landscape
Who Rebuy Engine competes with, and how they differ.
Nosto is a full personalization platform (AI recommendations, site search, content merchandising, native CDP) built for stores that have outgrown Rebuy's cart-and-recommendation focus; several Shopify Plus brands have migrated from Rebuy to Nosto for its broader enterprise feature set.

Dynamic Yield, acquired by Mastercard in 2022, sells enterprise-grade personalization and A/B testing across web, app and non-retail use cases, targeting larger budgets and longer sales cycles than Rebuy's Shopify-only, self-serve model.
1 product reviewed on TopReviewed
Monetate competes on the same personalization-and-testing use case but is platform-agnostic rather than Shopify-native, and leans on experimentation/A-B testing tooling rather than Rebuy's cart-and-checkout-specific Smart Cart product.
1 product reviewed on TopReviewed
Bloomreach bundles personalization with a broader commerce search and CDP suite aimed at large enterprise retailers — a heavier, pricier alternative than Rebuy for brands that outgrow a single-purpose Shopify app.
1 product reviewed on TopReviewedLimeSpot undercuts Rebuy on price with a lighter recommendation engine (plans from $9.99/month) but does not support Shopify Plus on either paid tier, ceding the enterprise-Shopify segment Rebuy specifically targets.
