David
Shipmunks is a free resource site for solo founders building with AI tools. It has step-by-step guides and blog posts on SEO, backend and stack, AI agents, growth, and money. Each post carries something you can check: a test, real data, or a template. Free tools include MRR, NRR, and CAC payback calculators that state their formulas. Free downloads include CSV worksheets for MRR, NRR, CAC payback, and churn, a blank CLAUDE.md template, and three Claude Code subagent files.
