About us

Calkin is a Swedish company headquartered in Stockholm, on a mission to remove complexity from Excel and reduce the risk of costly errors.

We do this through our patent-pending technology that visualizes data flows, making it easier to understand, audit, and trust even the most complex spreadsheets.

Our team brings decades of hands-on experience as daily Excel users. We know the pressure of working up against deadlines and the frustration of discovering an error at the worst possible moment, or even after it's too late.

We've spent countless hours tracing issues manually, cell by cell, trying to understand what went wrong. Calkin was built to change that.
