Retention Strength for your next stage of growth
What got you here won't get you there
You’ve built traction. Revenue is coming in. Investors are watching.
But funnels leak. Sign-ups slip away.
Growth slows just when it matters most.
We help you build Retention Strength so customers stay longer, revenue grows steadily, and milestones get hit on time.
What works at 100 users
rarely works at 1,000. Or 10,000
Early adopters carry you. They were motivated. They fought through the clunky UX. New users won’t.
Feature creep set in. More options, more confusion, weaker adoption.
Attention got tougher. You’re no longer novel. You’re competing with customer habits, and those habits are to use something else.
Growth doesn’t stall because the product is bad.
It stalls because your behavioural systems haven’t caught up.
It's not your product. It's your Retention Strength. Let's bulk you up.
Build Retention Strength, before adding features.
Growth doesn’t stall because your product is weak.
It stalls because customers don’t stick.
Audit the shift → see how user and product behaviour changed as you grew.
Rebuild the systems → strengthen onboarding, adoption flows, and engagement so customers stay longer.
Lock it in → clear fixes, measurable outcomes, and growth that compounds quarter on quarter.
Every step builds your Retention Strength. And gains last long after we’ve gone.
The workout plan
Weeks 1-2
Diagnose
Map your user journey. Pinpoint where friction crept in. Spot which behaviours broke at scale.
Weeks 3-5
Rebuild
Test new systems:
+ onboarding that works for unmotivated users
+ guided paths through complex features
+ engagement loops that build habit
Weeks 7-8
Handoff
Your playbook. Your trained team. Systems that keep compounding as you grow.

Challenges for scaleups
Patterns that scaleups encounter and how Behaviourgym fixes them.
Current users act different to old ones
rebuild onboarding for today’s users.
→
Retention strength is weak
design habit loops and rituals to take people deeper.
→
Team can’t agree on the problem
replace opinion wars with clear behavioural data, so the whole org trains toward the same KPIs.
→
You get peaks of attention, but not consistent return use.
identify which triggers create repeat use, and systematise them so growth compounds.
→
Early growth masked leaks. At scale, they became obvious
design systems for every segment.
→
Growth feels random
isolate the behaviours that predict retention and revenue, then train them.

Quarterly Cycle 90 day fit
The Compounding Plan
Build strength that lasts.
With our Quarterly Retainer, we work alongside your team to build and maintain Retention Strength in your product and business.
Retention metrics that hold up to investor scrutiny.
Growth that feels steady instead of spiky.
A clear plan for the next quarter’s focus.
