Gu had been thinking about problems he could solve through technology. That was beginning to become the standard refrain among aspiring entrepreneurs: find a problem to fix. Lately, founders had become so overzealous in this endeavour that problems were created that never existed, or problems were over solved to the detriment of practicality, such as iPad menus at airports, which took live servers to explain to frustrated users. It took Gu six months of working in New York to develop some real problem that wasn’t being attacked from all sides by 20-and 30-somethings salivating to stumble upon the next TaskRabbit – a company that lets you find strangers who will do small tasks via an app. But then Paul realised the biggest unsolved problem was all too obvious: he knew too many contemporaries who were broke.
