Slack is a cloud-based team communication platform developed by Slack Technologies, which has been owned by Salesforce since 2021. Slack uses a freemium model. Slack is primarily offered as a business-to-business service, with its user base being predominantly team-based businesses while its features are focused on business administration and communication.
Slack originated as an internal communication tool used within Stewart Butterfield's company Tiny Speck, during its work on the development of Glitch, an online video game. These communication tools were initially built around the Internet Relay Chat (IRC) protocol and included scripts designed to automate and organize file exchanges among its development team. By October 2012, Stewart Butterfield realized that Glitch was not going to be profitable. As a result, he decided to change the direction of his company and repurpose the communication tools they had developed into a new product.
