saas-economics-efficiency-metrics
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.
