2015 - Slack aquiered screen-sharing tool Screenhero to stand out over Cisco Spark


Slack, the workplace communication service, acquired Screenhero, a screen-sharing tool for teams, with plans to incorporate its features. Screenhero provides a range of collaboration tools, including voice chat, faster screen sharing between individuals and the option to have multiple mouse cursors interacting over various applications. The startup's six-person team will join Slack, and work to integrate and advance those features there. The Screenhero acquisition is Slack's second to date. It bought Spaces, a small startup also developing collaboration tools, in September.
