This is my dream. A company in between me and all kinds of service providers (energy, insurance, internet, mobile, let’s go crazy and add: mortgage, mobility) and just regularly switches me to the best offer while I retain service. They could get probably get away with a 10% fee and still deliver, because they can reverse auction their portfolio and get massively better deals than usually available. They can do KYC and vouch for my credit rating, keep my PII safer while putting my saved money to work in an investment account while bargaining for the lowest costs. Worth billions. We could then use those billions to buy stakes in the firms that give us shitty service to force them to put the customer first.
Sounds pretty awesome albeit vastly more complicated than what I had imagined. The idea of customers collective bargaining to force competition is neat.
It's not quite the same pitch, but I use privacy.com to set up a unique virtual card for every subscription I sign up for - that way, all in one dashboard and can stop them on demand. I also set the spend limit just above the current price so if there's a price hike it denies the transaction.
