Nimium

What Nimium does

Nimium d.o.o. za telekomunikacije i informatiku is a Croatian privately held IT services company headquartered in Zagreb that has operated since 2002/2003. The firm specializes in the design, implementation, maintenance, and consulting of enterprise IT infrastructure built on open source technologies, with deep specialization in GNU/Linux operating systems, Red Hat Enterprise Linux, containerization (Docker, Kubernetes), cloud platforms (OpenShift, OpenStack), storage (Ceph), monitoring (Zabbix), database (EnterpriseDB), email and collaboration (Zimbra), backup (Bacula Systems), and security tooling (Keycloak, firewalls). Nimium holds Red Hat Premier Business Partner status — the first Croatian firm to achieve this — and has been recognized as the "Red Hat Most Certified Partner" in the region; it is also the exclusive Croatian partner for Docker, Bacula Systems, EnterpriseDB, Roaring Penguin, and Zimbra, alongside an HP AllianceONE hardware partnership.

The company's business model is a mix of professional services (consulting, design, system integration, migration, proactive monitoring, and ongoing maintenance) and recurring revenue from reselling and supporting Red Hat Enterprise Linux subscriptions. Nimium serves a concentrated roster of large Croatian enterprise, government, telecom, banking, retail, and academic clients — including Hrvatski Telekom, Ericsson Nikola Tesla, Konzum, PBZ, the Croatian Ministry of Finance, HRT, Infobip, and CARNet — through a direct, relationship-driven enterprise sales motion. Distribution is exclusively direct (no reseller or marketplace channels). Beyond its core services business, Nimium has engaged in EU-funded applied research, notably a 2021 strategic co-development project with the Andrija Štampar Teaching Institute of Public Health to build a cloud-based air pollution detection system using machine learning and data mining, signaling limited but real diversification into domain-specific analytics.

Ownership is founder/management-led (Chairman Marin Bjeliš) with no disclosed external investors, no parent company, no subsidiaries, no M&A activity, and a paid-in share capital of just 2,630 EUR. The firm is actively operating, with an active recruitment pipeline and ongoing EU project execution, but shows no signs of venture-backed scaling, acquisitions, or international expansion beyond the broader Southeast Europe region.
