An honest breakdown of what this diagnostic can (and can't) tell you about your growth.
Founder or growth leader
$1M–$10M revenue, B2B or DTC
Know your rough numbers
Revenue, traffic, churn, spend - estimates work
Want objective diagnosis
Willing to face uncomfortable truths
Need to know WHERE to focus
Acquisition? Retention? Conversion? Economics?
Pre-revenue or pre-launch
Needs actual customer and revenue data to run
Marketplace or consumer app
Built for B2B subscriptions and DTC stores
Just want validation
The math might confirm what you don't want to hear
Is the problem acquisition, retention, conversion, unit economics, or spend efficiency? The tool isolates the primary constraint and explains why it matters more than the others right now.
The diagnostic delivers objective truth from your own numbers. The calculation engine adapts entirely based on your business type.
70% for SaaS, 40% for agencies. Used for LTV and payback period. You can override with your actual margin.
Month-by-month simulation where percentage-based churn compounds as your base grows. Correctly models growth deceleration and natural ceilings, not naive linear math.

Rough estimates work fine. The tool is designed for directional insights, not precise predictions. If you're within 20% on your inputs, the diagnosis will still be valuable. What matters is identifying the bottleneck, not decimal-point accuracy.
For B2B: the tool assumes ARPC stays constant. If you have significant expansion revenue (customers growing MRR over time), your actual trajectory may be better than the tool suggests. For e-commerce: the tool treats AOV as a constant, so if you have a strong upsell engine that raises AOV over time, your results may be conservative. In both cases, the bottleneck diagnosis will still be directionally correct.
Use your typical month or an average. Seasonality will make month-to-month numbers swing, but the underlying unit economics and bottleneck diagnosis will still be valid. The tool helps you see the structural problem, not predict next month's revenue.
When churn is percentage-based (e.g. 5% of clients leave each month), the number of clients you lose scales with your base. At some point, you're losing as many as you're adding. That's your ceiling.
The formula: new clients per month ÷ monthly churn rate = maximum client count. For example, 20 new/mo at 4% churn = ceiling of 500 clients. If your goal requires 600 clients, no amount of time gets you there without changing the inputs.
Not always. The tool counts every departing client as churn, but for project-based agencies, many departures are completed engagements, not dissatisfied clients. The tool recognizes this: when you select Agency/Services, the recommendations include an interpretation guide that separates true retention loss from normal pipeline cycling.
If you set your goal equal to (or near) your current revenue, the tool enters maintenance mode. The diagnostic can still show useful things: unit economics, churn health, concentration risk. But the key levers for margin improvement (pricing, delivery costs, client mix) are beyond what it currently measures.
The diagnostic uses smart, model-specific benchmarks, not generic ones:
It doesn't compare you to competitors. It shows what YOUR numbers require to hit YOUR goal, then flags if your current path is inefficient compared to what's achievable.
Yes. SaaS gets churn-adjusted growth simulations and subscription-based LTV:CAC. Agencies get the same model with 40% margins and project-completion-aware interpretation. DTC gets an entirely separate engine: conversion funnel, ROAS, CPA, repeat rate benchmarks, and interactive sensitivity sliders.
All calculations happen in your browser. Unless you choose to generate a shareable link, your financial data never leaves your device. If you do create a shareable link, the results (not the raw inputs) are stored so the link works for anyone you share it with.
That's actually the most valuable outcome. If LTV:CAC is under 1 or profit per order is negative, you lose money on every customer or sale. Scaling that just loses money faster. The diagnostic shows you this BEFORE you burn cash, not after.
No. This tool diagnoses WHERE your problem is. A growth expert helps you figure out HOW to fix it. Think of this as an X-ray that shows the broken bone. You still need a doctor to set it.
You can download your results as a PDF or generate a shareable link. If the diagnostic shows problems you need help fixing, you'll have the option to schedule a conversation. But there's zero pressure - the tool is useful on its own.
