I bet this data is worth (much) less than the cost to collect and analyse it.

It would be worth something for larger companies but for these WeWork will have only limited insight since they're unlikely to rent all or even a significant share of their total space from one provider. Lead generation is probably the ceiling.

Maybe they could do some targeted advertising/deals for various additional services. But probably not even that. Let's say they wanted to provide accounting services. Can they beat Mabel Luna? Will they have someone to answer a quick question about cash flow or depreciation?
