The Story Behind Fast Simon
Zohar Gilad and Adar Greenshpon founded Fast Simon, originally InstantSearch+, with a simple goal: make e-commerce search work better, so shoppers could find what they wanted.
As Fast Simon worked alongside fast-growing brands, the team saw that search was only one piece of the puzzle. Product discovery happens across the entire shopper journey, from category pages to personalized recommendations. And as catalogs grew, merchants struggled to scale their merchandising without losing creative control to black-box automation.
So Fast Simon built a complete product discovery platform that handles the heavy lifting and respects each brand's guardrails. Its Commerce-Native AI Model takes that further: instead of replacing merchandisers, it works alongside them, learning shopper intent and optimizing the discovery experience while the brand stays in the merchant's hands.
Merchants Define the Strategy. The Model Optimizes Within It.
Let Commerce-Native AI, built specifically for commerce, learn from shopper behavior together with your catalog, inventory, pricing, promotions, and merchandising rules, and handle the continuous optimization no team could do by hand.
