Our story

We were tired of integration being the worst part of the job.

StackSync started in 2023 in Gdańsk, built by people who had spent too long maintaining brittle pipelines between systems that should have just stayed in sync.

Why we built it

Every company we worked at treated data integration as a necessary evil. The best engineers got pulled onto glue code that no one wanted to own, batch jobs broke quietly, and two systems that were supposed to agree drifted apart between runs. We thought the model was backwards.

So StackSync is built the other way around: continuous instead of scheduled, two-way instead of one-direction, and observable instead of opaque. It reads the schema, maps the fields, and keeps your CRM and database honest with each other in real time, so the integration layer stops being the thing that wakes you up.

Where we are

We are a small, engineering-led team based in Gdańsk, Poland, serving customers across e-commerce, logistics, technology, healthcare, energy, and the public sector. Being in the EU shapes how we think about data residency and GDPR, and it is built into the product rather than bolted on.

Data reliability

Hanna spent years on data platform teams where the integration layer was the thing that paged people at night. She writes about sync semantics, idempotency, and schema drift.

Solutions engineering

Mateusz works with customers on connecting CRMs and databases that were never designed to talk to each other. He covers field mapping, migrations, and conflict rules.
