Do I need to connect my analytics?

It works best with real data. Connect PostHog, Mixpanel, Amplitude, Stripe or your CRM, or upload an export. Numbers you only type in are marked as self-reported until checked.

How does it judge product-market fit?

With at least two signals: the 40% very disappointed test, whether retention curves flatten, the share of organic signups, and what users say. It judges each segment separately.

Can it really lower my CAC?

It shows CAC and payback per channel, finds what pushes CAC up and ranks the levers to bring it down, like better activation, a tighter customer profile and referral loops.

Why fix leaks before acquisition?

Users who do not stay make every new signup more expensive. Fixing the biggest leak first makes every dollar of acquisition work harder.

The problem

Why this matters

Teams pay to acquire users before those users stay, and the money leaks out.

CAC creeps up month after month and nobody can say why.

Growth advice is generic because it never sees your real numbers.

Know if you really have product-market fit

The coach checks fit per segment with the 40% "very disappointed" test, retention curves and organic pull. If fit is not there yet, it tells you before you spend on growth.

Bring CAC down while LTV goes up

CAC, LTV:CAC and payback per channel, so you cut what does not pay back and grow what does.

Unit economics by channelExample

Channel	CAC	LTV:CAC	Payback
Referral	$40	9.0	2 mo
Content and SEO	$85	4.2	5 mo
Paid search	$310	1.2	19 mo

The growth strategy your data supports

Product-led, sales-led, marketing-led, partnership-led or community-led. The coach recommends one, shows the trade-offs and builds the loops and channels around it.

Growth motionExample

Motion	Fit	Why
Product-led	Best	Self-serve trial, $4 per staff
Partnership-led	Second	Payroll tools own the buyer
Sales-led	Not now	Contract value too low

Week-1 retention fell 4 points

New clinics from paid search retain 11 points worse than referral clinics. Diagnose before raising the budget.
