2015 Atlassian acquired team chat Hall

Atlassian, that providers services like JIRA, Confluence and the group chat tool HipChat, has acquired Hall, a group chat service for businesses. Both HipChat and Hall currently offer free starter plans for an unlimited number of users in a given team. For advanced features Hall currently charges $4 per user/month while HipChat’s plans start at $2 per user/month. Unlike Hall, though, HipChat offers more advanced features like video chat and screen sharing. With Hall, the company is acquiring new users in financial services, real estate, professional services and similar industries where Hall found its niche since its launch in 2011. The company will shut down Hall on June 30th, but current Hall users can now migrate their users, messages and files to HipChat.
