SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Analyze unit economics for PE targets — ARR cohorts, LTV/CAC, net retention, payback periods, revenue quality, and margin waterfall. Essential for software/SaaS, recurring revenue, and subscription businesses. Use when evaluating revenue quality, building a cohort analysis, or assessing customer economics.

Core Features & Use Cases

ARR bridge & cohort analysis: track beginning ARR, new ARR, expansion, contraction, churn, and ending ARR by vintage.
Customer economics: CAC, LTV, LTV:CAC ratio, and CAC payback period.
Retention & expansion: gross and net retention, logo churn, and expansion rate.
Cohort analysis & margins: cohort matrix and margin waterfall by revenue stream.

Quick Start

Ask to run an end-to-end unit-economics analysis for a SaaS business using ARR, LTV, and CAC data.

FAQPage Schema

How do I calculate LTV:CAC ratio and payback period for a SaaS business?▼

Calculate LTV:CAC ratio and payback period by analyzing customer acquisition costs against lifetime value and net retention metrics. This provides a complete view of SaaS profitability and customer economics for recurring revenue models.

How do I build an ARR cohort analysis matrix to track net retention?▼

Build an ARR cohort analysis matrix by tracking beginning ARR, new ARR, expansion, contraction, and churn by vintage. This reveals gross and net retention trends, logo churn, and expansion rates across subscription cohorts.

What's the best way to assess revenue quality for PE targets with recurring revenue?▼

Assess revenue quality for PE targets by evaluating ARR bridges, retention metrics, and margin waterfalls across revenue streams. This benchmarks subscription businesses against standard SaaS metrics to validate profitability.

Can I use cohort analysis to model a margin waterfall for subscription businesses?▼

Use cohort analysis to model a margin waterfall by mapping margins against revenue streams and customer vintages. This isolates expansion revenue impact and contraction effects on overall profitability for SaaS targets.

What is an ARR bridge and when do I need it for unit economics analysis?▼

An ARR bridge tracks stepwise changes from beginning to ending ARR, isolating new sales, expansion, contraction, and churn. You need it when evaluating revenue quality or building cohort analysis matrices for SaaS targets.

Why does customer economics analysis matter for SaaS benchmarking?▼

Customer economics analysis matters because it benchmarks LTV, CAC, and net retention against SaaS metrics to validate profitability. It exposes whether acquisition costs align with lifetime value and payback expectations.
