"I'd start by clarifying what ad-tech is in layman's terms. Ad-tech includes technologies that help companies promote their brand to their target customers in the digital landscape. These technologies help them understand their target customers, define the messaging that will resonate with them, and predict where they would likely see AND pay attention to the message or ad. Criteo Corp is one of the top players in the field and focuses on collecting diverse insights based on when, where, and what the person is doing. For instance, when you shop for clothes on Uniqlo, H&M, and Armani websites, as you click through all the clothes you see you like, Criteo Corp's tech records your clicks and tries to understand what you did and didn't like. They can collect information about you and others with similar preferences and needs and be able to show you recommendations or content that they think you will like. For example, when you Google things, you see ads for those on Facebook or Instagram. That's based on the kind of analytics that Criteo Corp can provide."
