Built by people who needed the loop to close.

DN1 started with a simple frustration: more data, more devices, and still no trustworthy answer to whether the protocol was working.

Mark Koivuniemi

Founder

Nearly a decade building systems in healthcare, from medical imaging at Fujifilm and Enlitic to clinical decision support at Phreable. Built DeltaN1 because he got tired of wearing three devices and still not knowing if anything he was doing actually worked.
