Tagalys was founded by Antony and Palani after realizing the limitations of e-commerce platforms in determining what products to display to online store visitors. Antony had previously resigned from his job to start an online retail business, which failed, but provided insights into challenges in online retail. Palani helped technologically. They then set out to build an intelligent engine that learns visitor interests to more effectively merchandise online stores, with a goal of becoming the world's best merchandising engine for online retail. Today, Tagalys processes over half a billion retail data points monthly to gain insights across various industries.
