What is unit-economics?

A framework for measuring how much a customer or transaction earns after the costs of acquiring and serving it. It covers metrics such as recurring revenue, customer lifetime value, acquisition cost, retention, payback, and margins.

Use it to analyze customer cohorts, recurring-revenue bridges, retention, customer concentration, acquisition payback, revenue quality, and margins.

It helps show whether revenue is durable and profitable, especially in subscription and software businesses where customer behavior changes over time.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked

Security

Grade A, and why

unit-economics scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Unit Economics Analysis

description: 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. Triggers on "unit economics", "cohort analysis", "ARR analysis", "LTV CAC", "net retention", "revenue quality", or "customer economics".

Workflow

Step 1: Identify Business Model

Determine the revenue model to tailor the analysis:

SaaS / Subscription: ARR, net retention, cohorts
Recurring services: Contract value, renewal rates, upsell
Transaction / usage-based: Revenue per transaction, volume trends, take rate
Hybrid: Break down by revenue stream

Step 2: Core Metrics

ARR / Revenue Quality

ARR bridge: Beginning ARR → New → Expansion → Contraction → Churn → Ending ARR
ARR by cohort: Vintage analysis — how does each annual cohort retain and grow?
Revenue concentration: Top 10/20/50 customers as % of total
Revenue by type: Recurring vs. non-recurring vs. professional services
Contract structure: ACV distribution, multi-year %, auto-renewal %

Customer Economics

CAC (Customer Acquisition Cost): Total S&M spend / new customers acquired
LTV (Lifetime Value): (ARPU × Gross Margin) / Churn Rate
LTV:CAC ratio: Target >3x for healthy businesses
CAC payback period: Months to recover acquisition cost
Blended vs. segmented: Break down by customer segment (enterprise vs. SMB vs. mid-market)

Retention & Expansion

Gross retention: % of beginning ARR retained (excludes expansion)
Net retention (NDR): % of beginning ARR retained including expansion
Logo churn: % of customers lost
Dollar churn: % of revenue lost (often different from logo churn)
Expansion rate: Upsell + cross-sell as % of beginning ARR

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
