Fast Simon launches AI personalization for Shopify Plus merchants

Personalization is shifting from a nice storefront trick to a merchandising engine, and Fast Simon is betting Shopify Plus brands will pay attention. The company said its new AI personalization tool is generally available for mid-market and enterprise e-commerce merchants, with the system built around brand presentation, collection strategy, product launches, promotions and inventory management.

Fast Simon introduced the product on June 11 in Los Altos, Calif., and made clear it was designed for brands on Shopify, especially Shopify Plus merchants, rather than for sprawling marketplaces or ultra-high-traffic environments such as AWS or Google. The pitch is straightforward: use behavioral signals to adapt the shopping experience across multiple surfaces, while keeping merchandising teams in control of how the site looks and what gets pushed.

That matters for gift retailers because the difference between a generic recommendation engine and a thoughtful one is often the difference between a browser and a buyer. Zohar Gilad, Fast Simon’s chief executive, put the company’s view plainly: “DTC brands do not want generic AI personalization that ignores merchandising strategy and inventory realities.” In practice, that means the software is meant to respond to what shoppers are doing without letting automation overrule campaign priorities or stock levels.

Fast Simon said early adopters of the AI Personalization for Merchandisers saw double-digit increases in revenue and conversion rates. For any merchant trying to sell gifts at scale, that is the number that matters most. A recommendation system that can move with inventory, highlight the right collections and adjust to behavior in real time can make a site feel more bespoke without adding a human stylist to every transaction.

The company said the launch follows earlier AI merchandising tools it rolled out during 2026, including an AI agent that helps merchandisers optimize products and collections. Fast Simon also said its platform already powers shopping optimization for thousands of merchants and global brands, and that it is a certified Shopify App and Shopify Plus technology partner. Founded in 2013 by Gilad and Adar Greenshpon, the company now bundles search, merchandising, personalization, a shopping AI agent and analytics into one Shopify-connected stack, a reminder that the next premium retail edge may be less about prettier pages than smarter decisions behind them.
