Crowdfunding is soliciting the crowd for capital - money - to support a project, cause, or venture. Crowdsourcing is soliciting the crowd for ideas and knowledge. In crowdsourcing, you ask the crowd (a large number of people) to contribute information, ideas, or work (often in the form of microtasks) toward a project. In crowdsourcing, the crowd may be paid or unpaid, however the contributions are often relatively small in nature. For instance, Wikipedia is a crowdsourced knowledge base where the crowd contributes to and asks for a self-check on the information published on the site.
