Does anyone have experience with the data brokerage industry?

I am in negotiations with a data broker. The business seems pretty healthy with good margins and a small team. While I have some experience in this space, I want to speak with folks who have bought, led, or invested in data brokers.

Some of the questions I have:
-What determines the winners and losers in this industry?
-What are the primary and secondary factors customers consider when choosing a data broker?
-Are there specific trends concerning supplier/customer concentration or consolidation?
-When larger companies in the space have been acquired, is there any moat that made them attractive targets?
-Any third-party data sources with more information on this space?

Please DM -- would love to speak
