Dropbox has silently bought workplace chat solution Zulip, according to TechCrunch. The financial terms of the acquisition deal were not disclosed in the said report.

A portion of the letter Zulip sent out to its customers read: "For our customers, tomorrow it's business as usual at Zulip. Please use all of the same channels to reach us with questions. As we make progress on integrating with Dropbox, I'm sure that we'll have more announcements about what the product roadmap looks like going forward."

Zulip is still in private beta. However, the service already has both desktop and mobile applications that will help users to share messages with their colleagues, whether it is private or public. Aside from the chat app, Zulip's features also include drag-and-drop file uploads, group private chats, notifications for missed messages, image pasting, and emoji, the report detailed.

According to VentureBeat, Zulip was founded by former Oracle workers Jeff Arnold, Wasseem Daher, Tim Abbott, and Jessica McKellar, among others. Paul English of MIT Sloan Entrepreneurship Center, and Meraki's Sanjit Biswas and Hans Robertson are among Zulip's investors, the report said.
