In June 2019, Slack went public through a direct public offering to reach a market value of US$19.5 billion. The companies also announced a commitment to work on integrating Slack with Atlassian services. On July 26, 2018, Atlassian announced the shutdown of its competing HipChat and Stride, effective February 11, 2019, and the sale of its intellectual property to Slack. Slack was previously compatible with non-proprietary Internet Relay Chat (IRC) and XMPP messaging protocols, but the company closed the corresponding gateways in May 2018. Īccording to Butterfield, 'Slack' is an acronym for 'Searchable Log of All Conversation and Knowledge,' which he chose in 2012 to replace the previous codename, 'linefeed.' Slack launched to the public in August 2013.

Slack began as an internal tool for Stewart Butterfield's company, Tiny Speck, during the development of Glitch, an online game. Slack runs on Windows, Linux, MacOS, Android, Windows Phone and iOS. In addition to these online communication features, Slack can integrate with other software. Users can communicate with voice calls, video calls, text messaging, media, and files in private chats or as part of communities called 'workspaces.' Slack also uses IRC-style features such as persistent chat rooms (channels) organized by topic, private groups, and direct messaging. Although Slack was developed for professional and organizational communications, it has also been adopted as a community platform. Slack is an instant messaging program designed by Slack Technologies and owned by Salesforce.
