                                over an hour a day in working with our
                                distributed team of engineers and PMs
                                across 7+ time zones.  We tried Slack,
                                Mattermost, and other team chat
                                products that claim to support
                                threading, and nothing handles
                                synchronous and asynchronous
                                communication so intuitively.

                                Akamai’s Zulip Enterprise deployment
                                connects over 2000 users around the planet.
                                The threading model of conversations
                                provides a large number of participants the
                                ability to engage in real, ongoing, and
                                substantive discussions, without the
                                overwhelming experience of many other chat
                                systems.  This coordination across far-flung
                                teams has had a significant, positive impact
                                on the happiness and productivity of our
                                personnel, regardless of location or
                                seniority.

                                Choosing Zulip over Slack as our group chat is one
                                of the best decisions we’ve ever made. Zulip makes
                                it easy for our community of 1000 Recursers around
                                the world to stay involved, even years after their
                                batches finish. No other tool has a user
                                experience that scales to a community of our
                                size.
