About Natrium

Most people think about sodium as something on a food label. Something to cut back on, maybe to help your blood pressure.

Almost no one thinks about it as a number that, when it drops too low, can cause seizures, brain swelling, and lasting damage.

In 2024, I spent time in the ICU because of mine.

Here’s the part that gets me. We’ve made it normal to watch your glucose, your blood pressure, your heart rate, your sleep. But sodium, which can land you in the hospital or worse, you can still only check by drawing blood and waiting.

That number tells you where you were. Not where you’re heading.

I assumed I was an edge case, because of how rare diabetes insipidus is. I wasn’t. Low sodium is the most common electrolyte disorder in hospitalized patients. It hits people with heart failure, cancer, kidney disease, the elderly, and people like me. And too often, it’s caught late.

It isn’t only the emergencies. Sodium that stays low over time is linked to attention problems, falls, and cognitive decline, harms that build slowly and quietly.

So we’re building a small wearable that tracks sodium continuously, so the trend is visible before it becomes a crisis.

I’m building it with Andrew Mancini, my co-founder and CTO, who invented the sensing architecture at the core of the device.

I built this for myself first. Then I learned how many people it affects. Ask around, you’ll probably know someone who has had trouble with their sodium.

That’s why we’re building Natrium.
