THE ORIGIN

I couldn't afford a nutritionist.
So I built one.

It took seven years. Now it fits in your pocket.

How a 25.5 stone smoker built a system that now runs his life.

In January 2011, I was 38. 25.5 stone. BMI 47. Clinically off the scale. Smoking 20 cigarettes a day.

I was eating ~4,000 calories a day. Mostly leftovers, pastries, and quick food. I avoided photos. I avoided holidays. I was disappearing from my own life.

The turning point wasn't a calculated health plan. It was a midnight impulse.

After seeing a deeply confronting family portrait, I did something desperate. At midnight, I entered a 10K. I didn't own trainers. I didn't know what a "macro" was. I just knew there was no way out.

I didn't need motivation. I needed a system.

I dressed in head-to-toe black and only ran when it was pitch black outside. That first night, I managed two miles. I was shattered, but I was elated.

Over the next few years, I lost 130 pounds. The midnight runs turned into 26 marathons and 10 ultramarathons.

But as my distances grew, I hit a completely different kind of wall.

I was data-rich, but insight-poor. I had the heart to run 100 miles, but I didn't have the fuel. I stared at heart rate monitors and sleep scores, but none of it told me what to eat. Standard calorie counters were utterly useless for athletic loads.

So I built the system I couldn't afford.

One that reads your biology and decides what to do — automatically.

Today, that system is KEXBI.

I know it works, because I stress-tested every single blueprint on my own biology first.

This isn't about calories. It's about having the energy to live your life properly.

THE PHILOSOPHY

Why it works this way

Why 100 athletes?

We limit cohorts to 100.

So we can observe real-world edge cases — not simulated ones.

Why an 8-field application?

We don't guess your starting point. The application defines it.

A 3-field form would give us an email address. An 8-field form gives us a biological starting position.

Why silence?

No notifications. No noise.

If your plan changes, it changes — without asking for attention.

Every notification is a decision, not a dopamine trigger. We shipped silence on purpose.

Why automation, not advice?

Advice is periodic. Your biology isn't.

So the system runs continuously — and updates your plan in minutes.

KEXBI doesn't replace the nutritionist's knowledge — it replaces the feedback lag.

WHAT IT GETS YOU

The Cohort 001 Exchange

Your commitment

  • Connect your wearable
  • Log honestly for 8 weeks
  • Challenge anything that looks wrong
  • The engine calibrates on your edge cases. Push it, and tell us where it breaks.

What you keep when beta closes

  • Your full plan history and diagnostics
  • Founder pricing for life
  • Priority access to future cohorts

You leave with a calibrated plan — even if you don't continue.

In six months, we will turn off the marketing site entirely.

After Cohort 003, we stop marketing.

If the product is good enough, athletes will tell each other.
