Startcrowd is a social network facilitating AI projects. On Startcrowd, requesters can post their projects, and other participants can complete them. In a future iteration of Startcrowd, contributors will be able to get paid with a blockchain token. The Startcrowd product is already launched (without the blockchain feature).
