AGCS (formally AdGibbon) was founded in 2011 by Niels Berkhout and Justin Campbell in the city of Amsterdam. The company first started trading as a self service mobile rich media platform and ad-serving solution. As the digital landscape evolved, so did the company and in May of 2016 the company re-branded to AGCS offering a service approach supporting creative agencies, media agencies and premium publishers HTML5 production support for display campaigns. Our key markets of operation are the UK, Germany, Netherlands, Switzerland, Austria and Australia. Here at AGCS, we code banners, and make sure that campaigns run on time.
