Twitter announced it has acquired Quill, a business-focused messaging service meant to compete against the likes of Slack. According to TechCrunch, “Quill is not making the cut in the acquisition: it will be winding down as an app” as Twitter works to incorporate many of its features into its own service. From the report: Quill notes in a brief announcement on its site that users will be “able to export your team message history until 1pm PST, Saturday, December 11th 2021, when we will be turning off our servers and deleting all data.” It will issue refunds for all active teams. But the team and its IP are joining the flock: Specifically, Quill’s people will be joining Twitter’s Experience organization to work on messaging tools, specifically Twitter direct messages. Pettersson will be taking a role as product manager, reporting into the Conversations team under Oji Udezue, Twitter tells me.
