Stop guessing. Start seeing the pattern.
Your child's Dexcom generates thousands of readings a week. Poseidon turns that flood into patterns you can actually use. We've all been there - sitting in the endocrinologists office while they scroll through multiple daily graphs and ask you why you had a low on a random Tuesday last month. There has to be a better way.
Three problems every T1D family knows by heart.
Too much data, not enough signal
Dexcom shows you what happened. Poseidon shows you what keeps happening.
No way to match lifestyle with data
Log your meals, activity, and stress to see how they impact your glucose in real-time.
No help in between visits
Coming soon: Decision support AI to help you make informed decisions related to T1D care.
From raw CGM data to clear answers, in three steps.
Connect your Dexcom
No manual exports. Poseidon connects to your existing CGM data automatically.

Day-of-week overlays. School-time windows. Sleep periods. Activity impact. Weeks of data, finally organized.

Poseidon was built because I needed it for my own son and couldn't find it anywhere. If that resonates, I'd love to hear from you.
