We Build the Infrastructure That Keeps Compliance Moving

Semansys is a Dutch compliance technology company, founded in The Hague in 2000.
For over twenty-five years we have helped enterprises, regulators, software vendors,
and accounting firms turn complex regulatory requirements into reliable, automated
workflows.

We are not a consultancy that happens to sell software. We are an engineering-led platform company that happens to understand regulation deeply — because we have been building for it since before most of our customers had a compliance team.

From XBRL pioneers to digital compliance leaders

What Drives Us

Compliance infrastructure is invisible when it works. Our job is to make sure it
always works: that every invoice reaches the right network, every report satisfies the right schema, and every document exchange carries the legal weight it needs to.

We believe the organisations best placed to build that infrastructure are the ones that participate in writing the rules. Semansys contributes actively to OpenPeppol, WE BUILD, and eIDAS 2.0 working groups — not as a marketing exercise, but because the implementation experience we bring to those tables makes the standards better, and the standards intelligence we bring back makes our platform stronger.
