Our Partners

Partners
Our success is also thanks to the amazing partners we work with, some of whom we've been collaborating with for many years. Our closest cooperation is with our sister company, Stereum Services FlexCo, in the fields of Ethereum software, node operation, and hosting services.
Stereum

Stereum Services FlexCo

Software & Service Provider for Ethereum
Founded in 2024, this sister company of RockLogic GmbH focuses on the marketing and distribution of various services. We’re proud to support them with IT infrastructure and our Ethereum expertise. In return, we frequently rely on their support for a wide range of blockchain-related topics.
Kalbeck

Kalbeck has been a reliable partner since 2017 for the execution of long-term client projects. We support them with project management for their work with financial institutions and provide technical expertise in automating IT infrastructure using technologies like VMWare and Ansible.
Centrovox

Centrovox Cable Distribution GmbH

Cables, Networks, Fire Protection, Consulting, Solutions
We share a close partnership with Centrovox. Since 2019, we have managed their entire IT infrastructure and, in close collaboration, built Centrovox’s data center. At the same time, we established one of our own data centers, and both are continuously being developed. We also regularly use Centrovox’s excellent facilities for internal RockLogic meetings, workshops, and conferences. Centrovox’s office building was recognized as a pioneer in eco-friendly construction with the EU Green Building Award back in 2013. It is powered 50% by its own photovoltaic system, and the remaining electricity is also sourced from green energy.
Lido

Lido

Liquid Ethereum Staking
Since 2022, we've been integrating Lido’s staking services into our open-source software Stereum. We're also one of the few 'Curated Node Operators' and provide servers for many thousands of validator keys on behalf of Lido.
Obol

Obol Labs, Inc.

Decentralized Validation Technology
By integrating Obol’s middleware Charon into Stereum in 2023, we made it possible to use cutting-edge DVT technology with ease—even without deep technical knowledge. Since 2025, Stefan Kobrc has also been actively involved in the governance of the Obol DAO, contributing to the project's stability and innovation.
