The document discusses two crowdfunding campaigns - one successful and one unsuccessful. The Scanadu Scout campaign raised over $1.6 million to develop a device that monitors vital signs and sends data to a smartphone. It succeeded because the company was prepared and had a working prototype. In contrast, the Skarp razor campaign raised $4 million but failed because it did not have a working prototype and was unprepared to handle the funds or fulfill rewards. Backers complained about delays and lack of updates from the company.
