Background
Stewart Butterfield possessed an incredibly rigorous, deeply elite background in advanced digital philosophy, complex user interface design, and massive-scale web community architecture.

Founding Story
Stewart Butterfield is a fiercely visionary Canadian-American software entrepreneur, highly strategic digital architect, and the profoundly influential CEO and co-founder fundamentally responsible for architecting the massively dominant Slack enterprise communications empire. Operating as the incredibly successful co-founder of Flickr, Butterfield aggressively recognized the massive, agonizingly chaotic friction of corporate email while attempting to build a highly complex multiplayer video game (Glitch) in 2009. After the massive commercial failure of the game, he relentlessly pivoted the entire company to commercialize the highly advanced internal messaging tool they had built to coordinate their remote team. By fiercely engineering a highly intuitive, massively integrated chat platform that completely eradicated enterprise email silos, his absolutely rigorous strategic leadership completely revolutionized global corporate workflows. His massive execution established Slack as a multi-billion dollar monopoly.
