Own Your Own Data.

For CTOs and CIOs who need to own their infrastructure.

Vendor-agnostic, cloud-native infrastructure designed for enterprises that refuse to compromise on who controls their data.

Who we are

About Us

Klarrio is a Belgian, cloud-native services firm that has been building large-scale data platforms for enterprise clients since 2016. We work across five countries with organizations in telecom, utilities, financial services, mobility, and government.


We build exclusively on open source. That means no vendor lock-in, no proprietary dependencies, and no situation where your data infrastructure is owned by someone other than you. Every platform we deliver is built to be run by your team, not ours.

Why Open Source?

Open source is the foundation. Here's why it matters.

We've built on open source from day one. Not because it's trendy, but because it's the only honest way to give enterprises full control over their own infrastructure. You can inspect it, modify it, and hand it to any engineer on your team. No licensing surprises, no vendor pulling the rug, no black boxes sitting in the middle of your data pipeline.


We work with stable, well-maintained projects like Kafka, Spark, Kubernetes, Flink. Cutting edge, not bleeding edge.

Enterprise Data Infrastructure, Built to Last

We work with enterprise organizations across telecom, utilities, financial services, mobility, and government,  anywhere large-scale data infrastructure needs to be reliable, sovereign, and built to last.

What We Do

Our Services

All of our services are built around the same principle: your team should fully own and understand what we build together. We're not here to create a dependency on Klarrio. We're here to build something your people can run on their own.

Platform Engineering

We design and build large-scale, cloud-native streaming data platforms tailored to your infrastructure. No templates. No shortcuts.

Consulting

Data architecture strategy, distributed computing, infrastructure advisory. We help you make the right decisions before a single line of code is written.

Support

Your platform doesn't stop needing attention after it's built. We provide ongoing support and maintenance from the same engineers who designed and built it, people who already know your architecture inside and out.

Built to be Handed Over

We train your engineers to run the platform independently. Every engagement ends with your team fully capable of owning, operating, and evolving the system on their own.
