The Founders
Meet Ash & Tom.
Two dads. A decade of reading the trials. The formula we'd take ourselves — built long before we wrote a single line of copy.

Hello from us
The two-minute version.
Why we started, what we built, and how to know whether KōJō is for you.
Recording soon. We'll publish the cut here as soon as it's ready.
Tom · Co-founder · Formula director
The literature obsessive.
Three years inside the clinical literature. Every formulation paper read. Every dose cross-checked against the trial that produced the result. Tom owns the formula end-to-end — what goes in, what stays out, and the published evidence behind every milligram.
He started this because the products on the shelf weren't honest about doses, and the ones that were honest weren't comprehensive. Rōnin is the formula he wanted to take himself — built to peer-reviewed standards, not retail-margin targets.
- 50 ingredients, every dose published
- Zero proprietary blends — ever
- Bioavailable forms only
- Reformulates when the evidence updates
Ash · Co-founder · Brand
Built it because he wanted to take it.
Ten years in tech. A young family. A working week that runs hot for nine hours and then turns into bath-time and bedtime. Ash didn't set out to build a supplement brand — he set out to find one he could trust. When he couldn't, he and Tom built it.
He runs the brand: the copy, the design system, the discipline of refusing every marketing trope the supplement industry leans on. Every claim on this site is backed by a published trial. Every photograph is real, not stock.

Why we take it
Smart. Backed by science. In the demographic.
-
We read the label.
Every ingredient. Every dose. Every active form. We dismiss 99% of what's on the shelf — and so should you.
-
We did the research.
Peer-reviewed human trials only. In vitro doesn't count. Animal studies don't count. The dose used in the study is the dose we use.
-
We take it daily.
Same scoop. Same time. Every morning. Built for ourselves before it was built for anyone.
-
We're in the demographic.
Two dads with busy lives. Built for the working day, the family evening, and every morning in between.
