Prayas Analytics
A/B testing for brick-and-mortar stores.

Prayas Anaytics helped retailers A/B test their stores, the way eCommerce companies A/B test their websites. We did this by continuously collecting data on customer movement using existing security cameras already in a retailer's stores.
We were a Y Combinator backed company (S15) and worked with several retailers including Barneys, Payomatic, and multiple Fortune 200 retailers.
