Custom ETL in C#
Pipelines you can read, test, and own — built on the library we created.
Need the library — and someone who already ships it?
Consulting for ETL and data integration from the people who built ETLBox. Code-first C#. Faster with AI. Tests in CI.
ETLBox is the product. ETLBoxperts is the small Berlin team that writes it — and that takes customer integrations when you want the same people on the project. The work is C# you own, not a canvas you rent. Because it is code, we test it, and AI can actually help us write it.
Your team already on ETLBox? We train, review, and write the hard flows with you. Need the whole integration? We run it, from first source to first reliable load.
With your team
Your developers already ship C#. We sit with them — train, review, write the awkward flows, leave a repo they can keep changing.
On us
First source to first reliable load. You get code, tests, and a fixed price after a free proof of concept on your data.
A canvas is a picture. Code is text a model can read, write, and we can still test. That is why three people in Berlin ship what used to take a floor of consultants — and why we are good at pipelines that need AI, not just pipelines built with it.
From a single stubborn flow to the warehouse around it. Same toolkit. Same tests.
Pipelines you can read, test, and own — built on the library we created.
Enable your developers to ship the next integration without waiting on a vendor.
Where the work is messy — extract, classify, decide — and keep the rest as tests.
SSIS estates, legacy systems, messy mappings. Extract, reshape, land clean.
Companies that have shipped data with us — and with the library we built.
Free · no obligation
Not a slide deck and not a toy dataset. We build a substantial slice of your integration — the awkward source, the rule that actually matters. If it fits, you get a fixed-price offer for the rest. If it does not, you still keep what we learned.
