Since Slack's launch in early 2013, the company has raised more than $320 million in funding-its $160 million round in April boosted the San Francisco company's private valuation to nearly $3 billion. The workplace messaging software has amassed 2 million daily active users since the service officially launched in February 2014-that's almost double the tally from six months ago. And many Slack users stay connected to the service an average of 10 hours daily, Underwood said.
