AdPushup
AdPushup was formed in 2014 with a simple idea: While A/B testing was becoming popular, no one was using it to optimize publisher-side ad layouts. Our founders built and launched a prototype to get proof-of-concept, which resulted in double-digit revenue growth for our first website. Since then, we’ve garnered top media mentions, raised multiple rounds of funding, and expanded to being a one-stop revenue optimization platform for web publishers. In addition to being a Google NPM AdX Partner, we’re a Microsoft Ventures backed startup, and winner of the NASSCOM Emerge 50 award. Today, we serve and optimize over 2 billion monthly ad impressions for our 300+ publishing partners worldwide.
