Why we built this

Health data changed my life. Then it almost broke me.

I've spent my entire career at the intersection of health and behavior change. As a professional athlete optimizing my training. As a coach and personal trainer helping clients at the gym. As a founder at Territory Foods, where we tried to make healthy eating so accessible that the habit just stuck.

During the pandemic, I went deep on my own data. Full-body MRI. 150+ biomarker panels. Microbiome testing. Stool tests. I had every number tracked in a meticulous spreadsheet going back a decade.

I tried working with the system: a large care team spanning functional medicine, primary care, nutritionists, personal trainers, specialists like cardiologists. And it was incredibly hard to line everyone up. Each provider had a slice of the picture, but it was up to me to connect all the dots. It was honestly pretty overwhelming.

All that knowledge actually drove my health anxiety up. Knowing more didn't mean doing more. It meant worrying more.

Then in early 2023, GPT-level language models hit a tipping point. I started feeding them my labs, my history, my questions, and for the first time something could actually synthesize it all. The burden lifted. Instead of me piecing together every data point, I had a tool that could help me figure out the three or four things that actually mattered right now. The relief was real.

But I didn't want to build for health optimizers like me. I wanted to build for everybody else: the parent at school pickup who got their labs back and thought "I should probably do something about this" and then never did.

The latest layer has been parenting. I'm a dad of two (8 and 4), with aging parents who've been through a couple of health scares. I'm somewhere in the middle, trying to help everyone: my own health, my spouse's, my kids', my parents'. Kasane grew out of that reality. With limited time, running businesses, being a dad, I needed a system that could tell me the small, risk-adjusted, genuinely impactful things I could do each day.

It's relieved so much of my health anxiety. And it's helped me help the people I care about care for themselves.

What we believe

A few convictions that shape everything.

🫀 Habits should come from your body.

Walking after meals means something different when your glucose spikes vs. when it doesn't. Generic advice ignores that. Your health context should shape what you practice.

🔬 Focus beats volume.

You can realistically form three to five habits at a time. Everything beyond that is aspirational clutter. Kasane enforces focus to respect how behavior change actually works.

🌱 Evidence first, then identity.

You start by walking after dinner tonight. And tomorrow. And for 21 days. The evidence accumulates. The identity follows. You become someone who takes care of themselves by actually doing it.

🍂 Habits are seasonal.

Some layers stay forever. Others come and go. An elimination diet during a flare. Extra mobility work after tweaking your shoulder. Your practice breathes with your life, and that's by design.

📊 Your data should work for you.

Health data sitting in portals is inert. Health data that shows up as "here's your next layer" is the whole point. The data is fuel. The daily practice is the product.

💕 Care ripples outward.

A parent who's sleeping better has more patience at bedtime. A spouse managing their digestion has energy for the weekend. Tend your own ground first, and the whole family grows from it.

Layer by layer.

Good soil isn't manufactured. Season after season, organic matter accumulates. Rain carries minerals deeper. No single season builds fertile ground. But stack enough of them, patiently and deliberately, and the soil holds everything.

We think health works the same way. No single habit changes your life. No single lab result tells your whole story. But stack them, a few at a time, and something emerges that's greater than the sum. Your ApoB drops. Your sleep deepens. Your energy shifts. Not because of one heroic change, but because of dozens of thin, deliberate layers, each one settling into the last.

To layer.
