We have built a blockchain data exchange. Concretely, this is a smart contract that sends money from one account to another once data has consensually changed hands. Note that, due to using a blockchain-based smart contract, only the data requester and data provider are involved -- there is no third party. Additionally, we have built a survey builder with many of the features of SurveyMonkey and SurveyGizmo, and an identity verification service.
