About Slack Technologies, Inc.
Slack Technologies is a computer software startup founded in 2009 by Stewart Butterfield, Eric Costello, Cal Henderson, and Serguei Mourachov. It is best known for its creation of Slack, a cloud-based team collaboration tool, launched in 2014.
Slack’s business messaging platform brings all communication together, creating a single unified archive accessible through powerful search. The goal is to improve efficiency in the office and make the work day more productive through less meetings and a reduction in emails. Slack provides teams with real-time messaging and file sharing for one-to-one and group conversations. It integrates with dozens of popular services such as Twitter, Dropbox, Trello, Asana, Google Docs, JIRA, MailChimp, Stripe, Zendesk, and others to help consolidate and make sense of the ever-growing flows of data that confront modern teams. Slack instantly syncs across devices on its smartphone app and website. The company offers a free version with upgradeable features at a cost to the user. Thousands of teams and millions of users have adopted the app since its launch.
The company was initially founded as Tiny Speck with the goal of creating a computer game called Glitch. The Slack tool was used internally by the company during the game’s creation, but when Glitch failed, Slack was unveiled to the public and the company changed its name to Slack Technologies. Based in San Francisco, and with offices in Vancouver, Dublin, Melbourne and New York, Slack is the fastest company to receive a billion dollar valuation. Slack's investors include many of the best-recognized firms in the world, including Accel Partners, Andreessen Horowitz, Social+Capital, KPCB, Google Ventures, Horizons Ventures, IVP, Spark Growth, DST, and Index Ventures. In 2016, Slack was ranked No. 1 on the Forbes Cloud 100 list.
