About us

Our Mission is Fast and Accurate Diagnosis for Everyone, Everywhere. Without a diagnosis, there can be no treatment. That is why prompt and quality scan reporting is our utmost priority.

Our story

The four of us formed Hexarad after we grew tired of seeing that no matter how hard we worked, patients were not receiving their diagnoses quickly enough.

This is huge problem – without a diagnosis there can be no treatment.

So we decided to take the lessons we learnt as doctors and techies to fundamentally transform how radiology works.

We built Hexarad – an end-to-end radiology platform to achieve our mission of fast and accurate diagnosis for everyone, everywhere. We're building technology that empowers people to do the best job they can, in a community that supports and nurtures them.
