THE DEATH OF GLITCH, THE BIRTH OF SLACK

Summary from the TLDR Founders newsletter

Glitch's shutdown in 2012 led to the creation of Slack after Stewart Butterfield and his team repurposed their internal communication tools into a new product. Although Glitch, a Flash-based game, didn't find enough players or adapt to mobile, its demise sparked the development of Slack to streamline team communication by replacing email and integrating various messaging tools. Within a year, Slack was launched, eventually leading to its successful public company debut.
