Fast Simon’s AI platform now tells merchandisers in real time which products are succeeding, overexposed, or underperforming — and what each decision is costing them.
Fast Simon, an AI-powered e-commerce optimization platform, has launched a capability that gives merchandisers real-time visibility into the true performance of every product in their catalog — and quantifies the opportunity cost of each merchandising decision across the full portfolio.
The update addresses a problem that has persisted even as AI tools have proliferated in e-commerce: that merchandisers overseeing thousands of products across fast-moving catalogs are still relying on delayed reports to make decisions that compound in real time. Generic AI tools have offered limited relief, producing recommendations that are often too vague to act on or based on signals that do not reflect current conditions.
Fast Simon’s updated platform is designed to answer three questions that most merchandising tools leave unanswered: how quickly a new product is becoming successful or failing, which products are receiving disproportionate visibility at the expense of better-performing alternatives, and how today’s merchandising decisions will affect the portfolio’s performance over time.
“The sooner merchandisers know the true performance of a product, the faster they can adapt and make more money,” said Zohar Gilad, co-founder and chief executive of Fast Simon.

The platform now also measures the short- and long-term opportunity costs of merchandising decisions across the entire catalog — a capability the company describes as the first of its kind in e-commerce. Rather than evaluating products in isolation, the system surfaces the revenue and profit a merchant forgoes when choosing one merchandising approach over another.
“Day-to-day merchandising decisions not only have consequences in today’s cart, but also in the future performance of the portfolio,” Gilad said. “Fast Simon unravels the complexity of opportunity costs, showing merchants the potential revenue and profit they are missing when making one merchandising decision over another.”
Fast Simon’s platform is used by brands including Steve Madden, Hillberg and Berk and White Fox Boutique, and integrates with Shopify Plus, BigCommerce and Magento.
