A quick search of Kernal’s database of startup ideas (use this invite code for early access) yields a number of ideas related to niche industries that could use the Yelp treatment. 

Popular ideas include Yelp/Glassdoor for apartment buildings and retirement villages, food delivery (with reviews for specific dishes), individual service providers (e.g., lawyers and programmers), and college athletic programs.

Over and above traditional review sites (which we covered extensively in this report), there is an opportunity to bring more transparency to industries and processes that need it most. Companies like VC Guide, Landscape, and Betterfront, for example, all aim to bring more transparency to the VC funding ecosystem.
