Slack plans to go public after hitting 10 million daily users

Slack plans to go public. The company behind the popular workplace chat app filed with the Securities and Exchange Commission today, revealing plans to list on the New York Stock Exchange under the symbol “SK.” In an unusual move, the public offering won’t raise money for Slack; it’ll just allow existing shareholders to begin selling their stock.
In its filing, Slack reported rapidly growing revenue, to $400.6 million from $105.2 million over the past three fiscal years.
