Market Size Analysis Top-Down Bottom-Up

Generate a dual-method market sizing analysis combining top-down and bottom-up approaches to validate opportunity size before building your territory plan.

About this prompt

This prompt produces a structured market size analysis using both top-down (TAM/SAM/SOM) and bottom-up (unit-level) methodologies for a defined product, market, and geography. It's built for AEs, sales directors, RevOps teams, and founder-led sellers who need to size an opportunity before allocating prospecting resources or building a territory plan. Use it in the pre-prospecting stage when you need a defensible number for internal alignment or to frame the market opportunity in a pitch.

The prompt

Analyze the market size for [PRODUCT] in [MARKET] within [GEO]. Provide both top-down (industry reports) and bottom-up (accounts × ACV) approaches. Include: TAM, SAM, SOM, growth rate, and key sizing
