Tam Sam Som Calculator

deanpeters/product-manager-skills
1.9k installs6.3k stars
Summary

If you've ever been asked "how big is the market?" and scrambled to defend a number, this walks you through TAM/SAM/SOM with citations instead of guesses. It adapts questions based on whether you're sizing B2B SaaS, consumer fintech, or healthcare, and adjusts for geography (US Census data hits different than global estimates). You can paste competitor marketing copy if you don't have your own yet. The output is investor-ready because it shows assumptions and data sources, not just a slide with "$10B market" on it. Pairs with the workshop-facilitation protocol, so expect numbered options and step-by-step prompts rather than a wall of text.
