I'm working on the inverse of Yelp, appropriately called Pley. Instead of a public service where users rate local companies, it's a private service where local companies rate their users. The only ones who would be allowed access are the owners and workers of service oriented companies.
It's meant to be a joke and to have something of mine I can actually throw up on github, but I plan on making it actually work anyway, just out of curiosity.
I thought of a similar idea, which you can feel free to take if you want to make the pivot. I thought a rating system for employees would be great. If an interviewer or agency or previous job has had a great or had experience with an employee, they can leave a rating for future employers whom may be interested in the same employee. Very similar to Amazons system. After all, we are all products to them. It can be linked to LinkedIn as well.
