Join us for Stanford TBP’s biggest event of the year: the annual Distinguished Speaker Series. This year’s speaker is Stewart Butterfield, founder and CEO of Slack Technologies and co-founder of Ludicorp, the maker of Flickr. One of the fastest companies to reach $1 billion, Slack continues to grow very quickly due to the immense popularity of its team collaboration product. Alexandra Suich, The Economist’s US Technology Editor, will be interviewing Mr. Butterfield on May 15th in CEMEX Auditorium.
