Startup Business Analyst Market Opportunity
This walks you through building a proper market opportunity analysis with TAM, SAM, and SOM calculations using both bottom-up and top-down methodologies. It's interactive, asking for your product details, target customers, and business model, then guides you through segment sizing, data gathering with citations, and validation checks. The output is a comprehensive markdown report with all the sections investors expect to see, including sanity checks against public company benchmarks. It's opinionated about being conservative on projections, which is smart. The whole process takes 30-60 minutes and integrates with other Claude skills for financial modeling. Honestly, this is the kind of structured thinking early-stage founders skip and regret later.
