Summary
Daniel Stewart Butterfield is a Canadian billionaire entrepreneur and designer best known for co-founding two transformative internet platforms: the photo-sharing site Flickr and the team-messaging application Slack. Born in a remote log cabin in British Columbia, Butterfield transitioned from a background in philosophy to become a central figure in the tech industry. He co-founded Ludicorp in 2002, which birthed Flickr, and later established Slack Technologies, which was eventually acquired by Salesforce in one of the industry's largest acquisitions. Recently, his legacy at Slack has come under focus as new competitors like David Sacks' startup Glue emerge to challenge Slack's market dominance in the enterprise messaging space.
