Who we are…

PLAYGROUND XYZ, a Division of GumGum, is an advertising technology business headquartered in Sydney with operations in Australia, New Zealand, Singapore, London, Los Angeles and New York.

Our mission is to master the art and science of maximizing attention. To do this, we’ve built the world's first AI that can measure how long an ad was looked at (a metric we call Attention Time). Fueled and verified by real eye tracking data, but able to throw off the shackles of panels and instead scale infinitely across the world wide web, our AI is set to revolutionize the way that digital media is measured, bought and sold.

We're a fast growing business with every major agency group and a great list of top tier publishers using our technology. We’re a team of mobile experts with an unrelenting focus on quality products and tech.
