A recent Vanity Fair profile of Twitter founder Jack Dorsey ends with an anecdote about an inspiring speech he gave to the assembled staff at his new mobile payments startup, Square . The internal "TownSquare" meeting took place on his 34th birthday last November, and it is a remarkable statement by a young CEO who is finding his voice and trying to impart it onto his company. Fortunately, somebody captured the speech on video, which I've obtained and present to you above. The 15-minute speech is succinct and to the point. Every startup founder should watch it. It is about design and building excellent products. "Everything we do here is design," he says. It is about the importance of telling good stories through your products and editing them down to their core narrative. "We need to present one cohesive story to the world," he notes. Dorsey gets his point across, appropriately enough, by telling the story of the Golden Gate Bridge.
