So far, it looks like they are supported by VC funds. I can't find any info on how they intend to become profitable but a few comments, drawn from memory, suggest they are expecting to fund with ads and a couple of people have suggested they will have a subscription service.

However, I can't find anything official about either and Wikipedia isn't very helpful. They do have some information about their existing funding:

A part of me thinks this type of thing would make a good not-for-profit enterprise. I'd even consider some sort of government backing. I'd say a service like that has good social potentials and can help society to make nformed choices.

I'd think so as well! But as we have seen in healthcare and other sectors, regulatory capture is possible, if not probable. Though, to be fair, the credit bureaus are in a similar niche and they are frankly a catastrophe. It seems that any 'word of mouth' type business or board that is of any use will eventually become useless as they try to squeeze blood from turnips. Subscriptions/payment may be better, like The Negro Motorist's Guidebook of the 1950's.

Yeah, I'd think it'd have to be a not-for-profit enterprise with some sort of forced independence and verification. I keep mulling it over and thinking that it's be simple to do, but each idea I come up with finds me also finding ways it can be abused. So, it's not really that easy, I suppose.
