San Francisco -- Atlassian, an Australian developer of collaboration software for product teams, said on Wednesday it has acquired San Francisco-based HipChat, developer of a hosted private chat service for companies and teams. Financial terms of the deal were not disclosed. "Connecting and sharing ideas in real-time helps teams move faster, and HipChat does this better than any other product I've used," said Mike Cannon-Brookes, the CEO of Atlassian. HipChat has more than 1,200 customers, including Groupon, HubSpot and WIRED. Atlassian will incorporate the company into its portfolio of software. HipChat's three co-founders -- Pete Curley, Garret Heaton and Chris Rivers -- will join Atlassian in unspecified roles.
