finances
by whawkinsiv
"Use this skill when the user needs to build a financial model, calculate unit economics, understand MRR/ARR/churn, or figure out their quit number. Covers SaaS metrics, CAC/LTV, burn rate, cash flow modeling, and making unit economics legible for non-finance founders."
validate
by whawkinsiv
"Use this skill when the user needs to validate a business idea, test demand before building, run a smoke test, create an MVP experiment, or decide whether an idea is worth pursuing. Covers demand validation, smoke tests, fake-door tests, landing page experiments, and go/no-go decision frameworks for bootstrapped founders."
