Slack's Stewart Butterfield Shares His Philosophy of Startup Success

After selling Flickr to Yahoo! in 2005, co-founder Stewart Butterfield was on the lookout for his next big thing. While trying to develop an online video game, he discovered an easy way to coordinate his team’s messages and files all in one place. This tool became the workplace messaging platform Slack, a fast-growing business app that was valued at $2.8 billion in April. Butterfield, who studied philosophy at Cambridge, joins us to talk about his career as part of our First Person series on local leaders and innovators.
