The story of Prefixbox

Our Story

Prefixbox was started as a passion project in 2014 by our CEO, Istvan Simon. Having worked on Bing at Microsoft, Istvan knew the power of intelligent search and turned to a group of trusted friends to help create a reliable Autocomplete solution for Ecommerce stores.

The team quickly discovered that online stores needed more than a rich autocomplete; they needed a fully optimized search solution. Thus, they began building a data-driven product search and discovery solution with insightful analytics that continues to evolve and make finding products easier for millions of people.
