Flickr cofounder Stewart Butterfield raises another $43m for Slack




This Week in Startups show

Summary: In the mid 2000s, Flickr was a red hot startup. Cofounder Stewart Butterfield gets really honest with Jason talking about the early days of Flickr (initially as a tool for a failed game company), its acquisition by Yahoo and how he and the burgeoning photo site changed there. His next big project, Slack, is a IRC-style workplace chat tool that's the first product from his next company, Tiny Speck. Listen in to find out how this, too, was an enterprise tool born of a game that didn't last.
