Measurement & growth infrastructure

Live

Where are the highest-risk gaps in analytics, attribution and revenue tracking — and is the measurement system reliable enough to scale?

AI Growth Infrastructure Assessment

Audit how acquisition, GA4/GTM tracking, CRM, attribution and revenue data work together, identify measurement gaps that distort growth decisions, and receive a prioritised 90-day implementation roadmap.

Growth infrastructure maturity and data-confidence scores

Unit economics & growth scenarios

Live

Do LTV, CAC payback and retention economics support higher acquisition spend — and which improvement would create the strongest growth leverage?

Predictive LTV & Payback Calculator

Model contribution LTV, LTV-to-CAC ratio, CAC payback and retention scenarios to test whether unit economics support acquisition scaling, pricing changes or retention investment before committing more budget.

Conservative, base and growth scenarios through day 180
Contribution LTV, LTV/CAC and CAC payback analysis
Retention sensitivity and required-improvement modelling

Conversion funnel & CRO

Live

Where is the highest-value conversion bottleneck, what could improving it be worth, and which experiment should you prioritise next?

Funnel Analysis & Experiment Planner

Analyze SaaS, ecommerce or lead-generation funnels, identify high-impact conversion bottlenecks, compare modeled revenue opportunities and turn the priority transition into a structured CRO experiment plan.

Stage-level conversion, drop-off and evidence diagnostics
Revenue-impact Opportunity Matrix and targeted improvement scenarios
Business-specific CRO hypotheses with A/B planning handoff

Experiment design & statistical evaluation

Live

Can the experiment detect a meaningful effect and support a reliable decision?

A/B Test Calculator

Plan A/B test sample size and experiment duration, then evaluate Control versus Variant results with transparent statistical assumptions, confidence intervals and conservative decision rules.

Pre-launch sample-size and duration planning
Relative or absolute minimum detectable effect
Post-test statistical significance and confidence interval

Marketing performance

Live

How much should marketing invest to reach the revenue-growth target — and how risky is the plan?

Build a risk-adjusted marketing budget range from the last completed month, compare Conservative, Base and Upside outcomes, and assess scaling risk without assuming flat CAC.

Base-to-Conservative risk-adjusted budget range
Revenue and customer scenarios at one planning budget
Optional 12-month benchmarks and evidence-gated historical diagnostics

When to use Growth Tools

Use a tool when the next growth decision needs evidence.

MEASURE

You cannot trust the numbers

Use the assessment when tracking, CRM, attribution and revenue reporting disagree — or when growth decisions rely on manual reconciliation.

MODEL

The economics need a decision

Use the calculator before scaling acquisition, changing pricing or deciding whether retention improvements can shorten CAC payback.

OPTIMISE

The funnel or test needs a reliable priority

Analyze conversion drop-off and modeled revenue impact, then use the A/B calculator when the priority opportunity needs a reliable experiment plan.

IMPLEMENT

You know the gap, not the sequence

Connect tool findings to analytics infrastructure, conversion optimisation, unit economics and growth strategy work when priorities need an implementation path.

Productised expertise

The tool identifies the decision. The practice builds the system behind it.
