What this skill does
Purpose Determine whether your SaaS business model is fundamentally viable and capital-efficient. Use this to calculate unit economics, assess profitability, manage cash runway, and decide when to scale vs. optimize. Essential for fundraising, board reporting, and making smart investment trade-offs. This is not a finance reporting tool—it's a framework for PMs to understand whether the business can sustain growth, when to prioritize efficiency over growth, and which investments have positive returns. Input Works best with: The question you're answering (can we scale? raise? extend runway?) or the metrics you want evaluated. Also useful: Your numbers — CAC, gross margin, burn, runway, magic number — partial data is workable. Anything supplied with the invocation itself — text after the skill name, a pasted context dump, or an appended ARGUMENTS: line — counts as answers already given. Use it and skip whatever it covers; don't re-ask. Arriving empty-handed? That works too. Use it as a reference: read the metric sections relevant to your stage and decision. Example invocation: Are we efficient enough to scale? CAC $9K, gross margin 72%, burn multiple 2.1, magic number 0.6. Key Concepts Unit Economics Family Metrics that measure profitability at the customer level—the foundation of sustainable SaaS. Gross Margin — Percentage of revenue remaining after direct costs (COGS). Why PMs care: A feature that generates $1M revenue at 80% margin is worth far more than $1M at 30% margin. Margin determines which features to prioritize. Formula: (Revenue - COGS) / Revenue × 100 COGS includes: Hosting, infrastructure, payment processing, customer onboarding costs Benchmark: SaaS 70-85% good; <60% concerning CAC (Customer Acquisition Cost) — Total cost to acquire one customer. Why PMs care: Shapes entire go-to-market strategy. Determines which channels are viable and how much you can invest in product-led growth. …
