Why I started BOK

I spent years feeling wired but exhausted while every test came back "normal."

BOK is the tool I wanted then—an OS that reads your nervous system and shows which foods and habits actually help you recover.

WHY WE START THIS FOUNDING PROGRAM

This Is More Than a Product.
This Is a Health Revolution.

For decades, health advice has been one-size-fits-all.
We are building ANS AI to personalize health at the nervous-system level.

A New Model of Health

Personalized guidance based on your Autonomic Nervous System.

You Are a Co-Creator

Your daily data trains the world's first ANS LLM.

Founding 100 Mission

We're building future medicine together.

Why It's Only $29.90

We subsidize the hardware because your real-world data is more valuable to us than the price you pay.

Actual hardware cost: over $200

We cover the cost

You contribute the data to train the ANS AI

Why Only 100 Spots?

Building ANS AI requires more than large data.
It requires high-quality, human-reviewed data from people we can truly follow.
That's why this program is limited to 100 members.

This isn't a discount round.

It's the first cohort shaping the foundation of ANS intelligence.

Who This Is For

We subsidize the hardware because your real-world data is more valuable to us than the price you pay.

Zero friction. We offer a 30-Day "No Questions Asked" Refund Policy. If you don't find value in the data, just email the founders. We will refund your $29.90 immediately. We want committed pioneers, not hostages.

Can I invite my friends?

Choose wisely. We are building a high-density research cohort. If you know someone who is obsessed with data and health optimization, you may share the link. But if they do not fit this profile, please do not share. We are protecting the signal-to-noise ratio of this group. Remember, there are only 100 spots total. Sharing the link increases the competition for the remaining seats.
