## What it does

The plugin adds five skills to Claude: market sizing, financial modeling, team composition, competitive landscape and startup metrics. They fire on their own when your question touches the topic, so you never call them by hand.

Three slash commands sit on top. `/startup-business-analyst:market-opportunity` produces a market breakdown with TAM/SAM/SOM, `/startup-business-analyst:financial-projections` builds a three-scenario model with revenue, costs and runway, and `/startup-business-analyst:business-case` writes an investor-ready document. The fourth piece is the `startup-analyst` subagent, which picks up questions about competitors, team structure and customer acquisition payback.

You need the Claude CLI and internet access, because the market skills pull data from web research. No network means the sizing runs only on what you supply. The subagent model is set to `inherit`, so it follows your session default; the author recommends Opus for multi-market work or detailed models. Compensation benchmarks in the team skill are US-focused, so for other countries you feed in your own numbers.
