What Is Heart Rate Variability, and Why Should You Care?
The hidden signal your body is sending all day long — and what it reveals about your stress. Most of us know our heart rate. It's the number your smartwatch flashes after a workout, the beats-per-minute that climbs when you're nervous and settles when you rest. But there's a deeper, more revealing signal hiding just underneath it — one that says far more about how you're actually doing. It's called heart rate variability, or HRV. Once you understand it, you start to see your

The surprising reason a single breath can change how you feel. Have you ever caught a scent — lavender, fresh rain, something baking — and felt your whole body settle before you even realized why?

How Sōl Knows the Difference Between Stress and a Workout
The science behind a wearable that actually understands what your body is telling it. Here's a problem almost every wearable has, and almost none have solved. Your heart is pounding. Your pulse is up, your body's working hard. But why? Are you anxious — or are you halfway through a run? To most fitness trackers, those two moments look nearly identical. A racing heart is a racing heart. And that's exactly why most "stress" features on wearables are so easy to ignore: they cry

Overcoming Self-Doubt..Why I Almost Didn't Start
On grief, doubt, and finding out who I really am. I come from a long line of builders. Innovators, entrepreneurs, people who saw what didn't exist yet and made it real. In my family, ambition wasn't unusual — it was the water we swam in. One of my uncles is said to hold one of the highest IQs ever recorded. The story I grew up inside was one of brilliance and possibility, generations of people who did remarkable things. For a long time, I assumed that was simply who we were.

Embracing the Hidden Burdens of Being a Single Parent & the Quest for Inner Calm
On single parenthood, mental overload, and building the calm I needed. There's a specific kind of tired that single mothers know. It isn't just lack of sleep. It's the weight of being the only one. The only name on every form. The only one who remembers the dentist appointment, the field trip money, the prescription refill, the fact that we're almost out of milk. Two kids depending on me — and a mind that never, ever clocks out. People see a mom who's handling it. What they d

Why Calm Should Come to You
The simple idea behind Sōl — and why it could change how we handle stress. Here's something strange about modern wellness technology: it's gotten very good at telling us we're stressed, and almost no good at helping us do anything about it. Your smartwatch can see your heart rate climb. Your fitness ring can flag a rough night. The data is everywhere. But in the moment that actually matters — when your chest tightens before a hard conversation, when the anxiety creeps in at 2

Kia, and the Long Road Back
The story behind Sōl — and why I built it. I grew up on the back of a horse. Barrel racing wasn't just something I did — it was who I was. I was good at it, too. Fast, fearless, completely at home in the arena. There's a feeling barrel racers know that's almost impossible to explain to anyone else: that moment when you and your horse stop being two and become one. No commands. No hesitation. Just instinct, trust, and motion. For me, that feeling had a name. Kia. Kia was my re
