About PubGalaxy


We think like publishers because we started as one. Since 2001 we’ve been trying and testing every major ad space monetization product on the market as one of the top tech sites worldwide - We got to live and deeply understand publisher pains. In 2013 we decided to make website monetization a separate endeavor and share our expertise with publishers worldwide. That’s how PubGalaxy was born.

The company’s growth over the years is something that we are proud of and in 2017 we were recognized by Deloitte as one of the fastest growing technology companies across EMEA. We provide a holistic service that covers all aspects of monetization, so that you have a peace of mind. PubGalaxy’s team of close to 100 professionals takes care of not only your revenue growth but also all technical aspects, ad quality, traffic quality, demand partnerships, ad layout optimizations and UX. We don’t undermine transparency and long-term sustainability of your business, just the opposite – this is what we fight for.
