Refer-Back and fortune are under the same parent company, but are still very much competitors. This is more common than most would think and is getting to be more and more common as larger companies begin to buy up their competitors.
In this particular case, both companies have seperat marketing and affiliate companies and compete directly with each other. Which is step further than most corporations go, usually hireing the same marketing and advertising companies for multiple accounts and expecting the individual teams to compete. Here they are atleast using seperate companies to run those operations.
It’s a good deal.
By the way, I don’t work for either company, so i have nothing to gain by pointing this out.
