In 2012, Stewart Butterfield tried saving a game company, and that one workplace tool ended up becoming Slack

A failed online game, Glitch, unexpectedly led to the creation of Slack. Stewart Butterfield and his team developed an internal communication tool to aid game development. This tool proved so effective that after Glitch's shutdown, the focus shifted to making it a standalone product. Slack launched in 2013, simplifying workplace communication and quickly gaining widespread adoption.
