The founder
Greg needed this app. It didn't exist.
Greg has lived with type 1 for most of his adult life. Same meals, same doses — different results, day after day. Every tool he tried logged the chaos; none explained it.
So he instrumented everything. The number that kept explaining the unexplainable wasn't glucose — it was how hard carbs were hitting that day. That became the CarbIn Factor™. The CarbIn Factor became Mirri One™. And the people who joined to build it mostly carry CGMs of their own.
That's the whole origin story, kept short on purpose — the long version is worth your time.
What we hold ourselves to
We live this
Most of the team wears the hardware. Every feature ships only after it survives our own nights and weekends.
Numbers over noise
No cheerleading, no guilt. Big honest numbers, colored by status, and guidance that says why — or says nothing.
Confidence, not control
Diabetes doesn't do "perfect". We promise a steadier hand on the wheel — never a lecture about the road behind you.
The route so far
Diagnosis
Greg starts living the problem — and logging it.

Sensitivity modeled from his own data finally explains the noise.
