About Stackable
Your data, your platform
Stackable builds and supports the Stackable Data Platform (SDP): Apache Kafka, Apache Spark, Trino and more, managed by Kubernetes operators, running on-premises or in any cloud. Founded in 2020 in Wedel, Germany, by long-time open source contributors. Everything we build is open source.
Our story
Built by people who saw “open” platforms close
Before Stackable, our founders Lars and Sönke spent more than a decade building Big Data platforms for enterprises. Again and again they saw customers commit to platforms that looked open, until licence terms changed and the free version disappeared. Stackable is the platform they wanted to give those customers: fully open source, no proprietary layer, and supported by a team under European jurisdiction.
If the terms can change under you, it's not your platform.

“The Stackable team always gave us the feeling that we were their priority. We really felt that we were in good hands at all times. This level of commitment to our project and
this fast and technically sound service is something we have never experienced from others before.”
Jens Dennig
, Solutions Architect at Atruvia AG
“GBIF's transition to the Stackable Data Platform has been transformative; a much-needed modernization of our infrastructure.
It has enabled us to seamlessly migrate live services, standardize diverse data,
while continuing our commitment to following open data and open-source principles.”
Tim Robertson
, Head of Informatics, GBIF

Built to last
A data platform is a decision for years, not quarters. Here is why you can make it with us.
Your exit is always open
SDP is fully open source. Operators, code and documentation are public on GitHub. If you ever stop working with us, your platform keeps running.
Independent and well-backed
Our investors include IONOS, a European cloud provider, plus private investors.
CVE Numbering Authority
We assign CVE IDs and publish vulnerability records for our platform ourselves, with SBOMs in every release and VEX assessments for subscribers.
Certified for Red Hat OpenShift
SDP is listed in the Red Hat Ecosystem Catalog and runs on any Kubernetes, on-premises or in any cloud.
European company
Headquartered in Germany with a UK subsidiary and no non-European parent company. Your platform and your support contract stay under European jurisdiction.
Active members of the digital community
For us, community engagement and commitment to European values also means that we are involved in digital industry associations, societies and initiatives.
