Every product has muscles.
Most never train them.
That’s where we come in. Two women, twenty-plus years of behavioural battle scars, and one simple question:
What if products trained like athletes?
Meet the trainers
Two behaviour heavyweights who got tired of watching great products stall.
Hannah Lewis
The Drill Sergeant
The strategist who taught finance how to flex. Pricing, comms, behavioural influence. She built systems where millions moved on a single nudge. A heavyweight in growth and defensibility design.
Lauren Kelly
The Product Physio
The scientist who made tech behave. Professor of behavioural design, architect of systems, the one big brands call when behaviour starts to wheeze. A sprinter for growth, a tactician for scale.
Together? We’re the behavioural tag-team your product didn’t know it needed.
The most important question...
Why... a gym?
Well, we'd done the fancy workshops. Written the thick decks. Advised the giants.
And yet... the same story, everywhere:
Features shipped. Nobody touched them.
Funnels leaked. Investors frowned.
Teams hustled harder, and nothing stuck.
Decks don’t build muscle.
Hustle doesn’t build habits.
So we built a gym.
A place where products train the behaviours that make them strong: activation, engagement, retention, revenue.
Where teams leave fitter than they arrived.
Our philosophy
Focus. Form. Frequency.
One weak spot at a time.
Clean reps only.
Every week.
No hacks. No gimmicks. Just behavioural science turned into sweat.
Strength that compounds.
Products that hold their own weight, quarter after quarter.
Why us?
We’ve coached the giants.
We’ve seen every mistake twice.
And we know: growth isn’t magic.
It’s discipline. Reps. Form. Muscle.
This is the gym for products built to last.
