<h1class="center">Communication efficiency represents <br/> a massive opportunity.</h1>
<p>
Communication consumes a <ahref="https://blog.rescuetime.com/slack-and-email-cost/">huge fraction of time</a> for managers and knowledge workers, and the workplace chat revolution has done nothing to reduce communication load.
</p>
<divclass="intro_quote">
<blockquote>
Ironically, for some, email has now become the place for well-thought-out communications while workplace [chat] software has been inundated by thoughtless meme and emoji sharing.

The [chat] software goes from helping you work to making it impossible to get work done.

<p>Zulip’s unique topic-based threading combines the best of email and chat to finally make efficient communication possible.
</p>
<divclass="intro_quote">
<blockquote>
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.
<divclass="author">

Like email threads, <ahref="/help/streams-and-topics">Zulip topics</a> create a separate space for each discussion, so different conversations will never get in each other’s way.
See each message in context — no more scrolling up and down through dozens of messages to track down the topic of conversation.
</div>
</li>
<li>
<divclass="list-content">
Important messages won’t be missed, no matter what else is happening, and whether the thread is old or new.
</div>
</li>
</ul>
<divclass="quote">
<blockquote>
In fact now it seems strange to me to just fire off messages in Slack with no subject – that's chaos, madness. The genius of subject lines is that you can quickly and easily catch up on the messages you missed in your off-hours... This feature alone saves me hours a week.

Zulip’s unique threading saves me well 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.
