AFIRE Podcast 2023.02: Getting Data Right (Michael Mandel, CompStak)

Michael Mandel, Co-Founder and CEO of CompStak, a marketplace for CRE data, discusses how the use of data is (and is not) changing the practice of global investing.

When it comes to big data, alternative data sets, data science, and analytics—how do we know if real estate investors approaching new data resources in the right way? 

How is data changing the game and how can organizations make better use of it? Can we better understand the value of any given asset by counting the number of trees nearby? Can that replace the data fundamentals around leasing and sales that we have relied on for decades? Or is this simply an expansion of augmentation of what we already do?

Michael Mandel, Co-Founder and CEO of CompStak, sat down in January 2023 with AFIRE CEO and podcast host Gunnar Branson to talk about how investors need to combine a strong grasp of fundamental data with the more exotic new sources of insight coming to market. 

How should investors better discern the quality and the meaning of data as they compete in a fast moving and volatile real estate landscape? Listen now for more insights.
