What Fast Simon does
Fast Simon Inc. is a private, California-incorporated SaaS company founded in 2013 and headquartered in Milpitas, that operates an AI-powered product discovery and merchandising platform for mid-market and enterprise direct-to-consumer eCommerce brands. The product unifies AI Shopping Agents (conversational commerce), AI Search (semantic, NLP-based and visual), AI Merchandising, and AI Personalization into a single integrated system, complemented in late 2025 by three Agentic AI "Super Agents" — AI Shopping Assistant, AI Merchandising Assistant, and AI Analytics Assistant — that combine generative reasoning with automation for product discovery, assortment management, and conversational analytics. The platform is delivered through deep, certified integrations with Shopify and Shopify Plus, BigCommerce (Preferred Technology Partner), Magento, WooCommerce, Wix, Shopify B2B, and Microsoft Dynamics 365 Commerce, and is supported by an eCommerce API/SDK for headless and composable commerce use cases.
The company reports operations across more than 20,000 stores worldwide — including enterprise customers such as Steve Madden, HEYDUDE, Juicy Couture, and Fashion Nova — and publicly cites conversion outcomes of 15% to 22% in apparel/footwear via AI shopping agents, 3x–10x conversion lifts at named mid-market customers, and double-digit revenue and conversion increases among early adopters of its AI Personalization for Shopify product. Its marketing and distribution footprint includes content and SEO, comparison pages versus Algolia/Bloomreach/Nosto/Searchspring, PR placements (New York Times, Forbes, Inc.), agency channel partners, and a Tapcart Elite mobile commerce integration.
Commercially, Fast Simon generates revenue primarily through annual SaaS subscriptions (Growth and Enterprise tiers, plus an optional Premium SLA add-on with 99.999% uptime) with usage-based overage exposure, and goes to market through a hybrid motion combining product-led self-serve (no-code Merchandising Editor and AI tools) and an enterprise field sales motion led by a VP of Sales. The ~30+ person team is led by co-founders Zohar Gilad (CEO) and Adar Greenshpon (VP), with CTO Alexandra Faynburd overseeing technology and a strategic advisor (Peter Messana, June 2026) focused on scaling go-to-market. The company is privately held with no disclosed institutional funding, parent entity, or M&A history in the available data.
