GUT contact Germany | Professional Services | 350 | $30M | Germany | Zulip | Zulip | Collaboration | 2022 | n/a |
GUT contact implemented Zulip in 2022, deploying the Zulip application in October 2022 to support customer support operations and internal communications across its Germany-based contact center network. The deployment is self hosted and configured as a Collaboration platform, provisioned to support over 1,000 agents across three countries and focused on centralizing contact center messaging and internal team coordination.
The Zulip server was self hosted with LDAP integration for authentication and directory synchronization, aligning user provisioning with the company directory. Rollout included a month of parallel running, after which GUT contact reported fast onboarding and stable operation. Governance emphasized channel structure and operational use for customer support and internal communications, with configuration level controls mapped to LDAP groups. The deployment positions Zulip as the company’s Collaboration application for contact center and internal messaging functions.

Idrift | Distribution | 26 | $2M | Norway | Zulip | Zulip | Collaboration | 2020 | n/a |
In 2020 iDrift AS adopted Zulip as its Collaboration platform to improve internal IT and infrastructure collaboration and asynchronous communication for its distributed Norwegian team, replacing Slack after a summer 2020 evaluation. The company evaluated Zulip in the summer of 2020 and provisioned a self hosted Zulip server to centralize message history and support ongoing operational discussion review.
The implementation focused on asynchronous messaging patterns typical of Collaboration tools, configuring topic oriented threads and searchable message history to capture operational context for IT and infrastructure workflows. Zulip was used to structure incident discussion, change coordination, and routine infrastructure handoffs, supporting persistent context rather than transient real time chat.
Rollout was executed internally with the self hosted server model, keeping control of data within iDrift AS infrastructure and aligning access to the distributed team across Norway. iDrift AS reported smoother async workflows and an improved ability to review historical operational discussions after adopting Zulip, while the deployment maintained a narrow operational scope centered on IT and infrastructure functions.
