For over 20 years, GUT contact has been offering premium customer support, outbound sales and other German-language services. The company achieves top performance by putting employees in a productive and motivating environment. Company leadership makes mindful choices about the tools employees use to get their work done, and has successfully scaled the team to over 1000 agents.
Agents at GUT contact use Zulip every day to communicate with their team leads. “Most of our agents are in their 60s or 70s, so the software must be as simple as possible. That’s why we love Zulip,” says Erik Dittert, who’s been leading GUT contact’s IT team for the past 20 years.

“Our agents don’t need email accounts”
GUT contact relies on team chat for written communication within the company. “Our agents don’t need email accounts,” says Erik Dittert, GUT Contact’s Head of IT. “If someone has an email, they’ll get spam.” Instead, under Erik’s leadership, GUT contact has been self-hosting open-source team chat applications for years, upgrading as technology has evolved.
The company started with IRC, used an XMPP chat client for a while, and in 2019 moved to Rocket.Chat. “Rocket.Chat was a little bit better than our XMPP server,” Erik says. However, when Erik learned about Zulip, he was excited to check it out. “I installed Zulip, and the IT team played with the app. We loved it. The UI was just cleaner, easier,” Erik says.
Zulip’s topic-based threading model was transformative. With other chat apps, “the first person has a question about something, the next person has a question about something else. You answer the first person, and the second person is confused,” Erik explains. This doesn’t happen with Zulip’s topics.
“Topic-based communication is a big big big feature we love in Zulip.”

Smooth transition to Zulip
Erik showed Zulip to his boss and others at the company, and in October 2022, GUT contact made the switch.
“Zulip was quite easy to set up, and worked instantly. 1000 people — no problem,” Erik recalls. “I hooked up the Zulip server to LDAP, and our agents loved not having to remember a separate username and password.” Erik considered importing data from Rocket.Chat into Zulip, but in the end it was decided that the messy conversation history was not worth preserving.
Erik put training videos on the company’s intranet to explain the switching process, and to give an overview of key new features. Employees were encouraged to play around with Zulip, create channels, and chat with each other. After a month of running Zulip in parallel with Rocket.Chat, the old system was turned off.

Easy for anyone to use
GUT contact offers employees the flexibility to work from one of 10 offices across 3 countries, or from their home office. This makes Zulip a critical communication tool across all job functions. There is a channel for each department (IT, human resources, etc.), as well as a dedicated channel for each customer, where team leaders post daily updates.
For agents, many of whom are not fully comfortable with modern software, Zulip being easy to use is invaluable. "We checked out Microsoft Teams and Mattermost, and most of our users didn’t like these programs, because they didn’t know how to work with them,” Erik says. “In Zulip, agents love the “Combined feed” view,” which combines direct messages and channel messages into a single feed. “Unlike other chat apps, you don’t have to click on each channel separately to see unreads,” Erik explains.
Functionality for the most technical users
Members of the IT team use Zulip to collaborate from around the world. “We share code all the time, and the formatting and syntax highlighting is great,” Erik says. When they need to jump on a call, “The Jitsi integration is perfect. We don’t have to deal with emailing a calendar invite.”
Outside of office hours, Erik uses the mobile app to check on his message inbox. It’s easy to skim the list of topics to check if anything requires timely attention. “I love the clean mobile app and the push notifications,” Erik says. “The app is extremely fast — you click, and messages show up instantly.”
Erik meets up regularly with other technologists to “have a beer and talk about cool software.” In this 50-person group, “Zulip is quite a big theme right now,” Erik says.
“I love Zulip. I use it every day, every night.”
