Slack acquires Spaces, a document co-editor

Work chat company Slack has announced its first acquisition, part of the company’s efforts to build out a broader suite of productivity capabilities. Spaces, a two-person start-up, has been working on co-editing app — a la Google Docs — and Stewart Butterfield told me by email that they aren’t issuing new accounts at present, since they are ‘tearing up the roads’ to get Spaces technology integrated into Slack.

He promises a demo once the technology is ready for outside eyes.
