Cuculus GmbH is a German software company founded in 2007 that builds infrastructure for utilities and energy providers worldwide. The company develops the ZONOS IoT Platform, which connects millions of devices and processes billions of data points daily to support smart metering, grid management, and revenue protection across electricity, water, and gas networks.
The platform addresses the technical demands of modern energy systems at scale. Utilities face pressure to modernise aging infrastructure, integrate renewable sources, and operate efficiently - challenges that require robust, large-scale data processing and real-time device management. ZONOS handles these requirements across a global customer base, with Cuculus maintaining team presence in 21 countries and operating in 38 languages.
Cuculus employs over 150 people and remains privately held, allowing the company to focus on product development rather than external growth targets. The organisation has spent 17 years building expertise in utility software, positioning itself as an established player in infrastructure-critical applications rather than a newer entrant to the sector.
