PLAYGROUND XYZ is an advertising technology business headquartered in Sydney with operations in Australia, New Zealand, Singapore, London, Amsterdam, 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).

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.
