It just isn’t.
Sure it is. The contractors that actually do the work pay to be listed and receive the leads and work from porch thus porch does get paid for the data (LeadS) it gives to its contractors.
So Yes porch is selling the data they got from inspectors. On top of that we have no idea YET what else or where else that data will go in the future, het Thornberry used to swear he never sold data, and look how that story goes…
Semantics. Do they provide the clients information to other entities such as Realtor.com?
