Noticed this on Charles Tywhitt's website the other day: "independent user feedback from Feefo.com".
Feefo is doing very much what I described in this post. Gathering customer feedback on behalf of a supplier, aggregating it, and then providing reports/tools for the supplier to use on their own website. They are currently focussed on suppliers of products (like shirts) rather than services (like fixing taps), but the concept is the same.
At the moment, though, they have very few suppliers signed up, and of course getting critical mass of suppliers is as important as getting critical mass of feedback.
I do, though, really like the way that, once you have submitted feedback, they ask you to offer feedback on **any other company you have ever used**. So you could offer an opinion on your local butcher, or on you cable TV company. Feefo then (presumably) find some contact details for that company and tell them "hey, Bruce Greig says your company is great / mediocre / sucks. To get more useful feedback like this, you should consider signing up to Feefo". Great example of word-of-mouth marketing.
I struggle to find enough time to really get my head around what we ourselves want to do here. Certainly something. Question is exactly what, and with whom. We are talking to one other player in this space, who is working hard to provide really good solution to this problem, and we will back them (with time and effort, not money) and see how it pans out. I think.
