Stewart Butterfield co-founded Slack in 2013 from the wreckage of a failed video game company called Glitch — pivoting the internal communication tool his team built to run the game into one of the fastest-growing enterprise software products in history, selling it to Salesforce for $27.7 billion in 2021. Born in Lund, British Columbia in 1973, Butterfield previously co-founded Flickr — also from a failed game — which was acquired by Yahoo. His ability to find transformative products buried inside failed companies, not once but twice, makes him one of the most remarkable pivoting entrepreneurs in technology history.
