Austin Hay (00:00:00): From 2010 to 2020, we had the golden years of deterministic matching where it was very easy to run an ad and understand with precision who installed the app. Maybe you didn't know their name, but you actually would know their IDFA and you could tie that to their PII.

And so I am paying a lot of attention to how marketers make decisions with probabilistic data because most of the work that I'm doing now is actually saying, well, given that we don't have determinist data about a per certain audience or where somebody came from, how can I find other information that will create a model for 30% of the population and we can use that to extrapolate to a hundred.
