"The conversion lift is real. The AI understands shopper intent in a way our old system never could. Seeing a 13% lift like Petco did is now a realistic goal for us."

"Finally, an AI that isn't a black box. The 'glassbox' approach lets me see why products are ranked and override when needed. It's made my job more strategic."

Ben T., Digital Merchandiser · May 2026

"It's powerful, no doubt. But the '8 weeks or less' setup is intense and requires significant dev resources. Definitely not a plug-and-play solution, so be prepared."

Chloe K., VP of Digital · April 2026

"As a headless, API-first platform, it integrated cleanly into our composable commerce stack. The performance is solid, handling massive request volumes without issue."
