An anonymous reader shares a TechCrunch report: Atlassian today announced that it has acquired project management service Trello for $425 million. The vast majority of the transaction is in cash ($360 million), with the remainder being paid out in restricted shares and options. The acquisition is expected to close before March 31, 2017. This marks Atlassian's 18th acquisition and, as Atlassian president Jay Simons noted, it is also the largest. Just like with many of Atlassian's other acquisitions, the company plans to keep both the Trello service and brand alive and current users shouldn't see any immediate changes.
