I'm building Somnus Technologies in Wisconsin as private, on-device infrastructure for sleep wellness. The problem we work on is snoring and nighttime breathing. Tens of millions of people live with it, and most never get a clear read on it.

Our first product is Nightsong^™. It turns the phone you already own into a sensor for sleep and snoring and gives you one honest read against your own baseline each morning. Nightsong is a wellness and longevity product from Somnus Technologies. Your recordings stay on your phone unless you choose to send them.

The Somnus Index^™ is a wellness score. It is one you-versus-you number from snoring and breathing steadiness overnight.

The engine runs on your phone. 60 held-out sleep-lab recordings, from an outside library of 287 expert-labeled overnight recordings. Every engine change is checked against them; none are used to train or tune it. Plain, fixed checks keep it honest. We are clear about how it is built and disciplined about what we claim.

Most of this category ships a better gadget and runs on your data. We went the other way. Privacy is built into how it runs, not written into a promise. The company underneath the app builds on-device sensing and a scoring standard.

Somnus is a small team, on purpose. We own every line of code and every decision, and we answer for both.

I've spent my career turning underperforming businesses into focused, high-growth companies. I know the difference between running large operations and building one from nothing.

Private by design. Wellness and longevity, measured against your own baseline. Every night adds to your baseline. Night 30 says more than night 1.

I write every article in the Learn library myself. The rule for each one is the same rule Nightsong runs on: say what the evidence supports, name the source, and stop there. Where a claim comes from published research, the article links to it. Where the answer is a conversation with a clinician, the article says so.

I use Nightsong every night. Most of what is in the library started as a question about my own trend line.
