A market sizing slide from public data with AI produces TAM, SAM, and SOM estimates backed by publicly available sources. You enter your product category, target customer segment, pricing model, and geographic focus. AI pulls market data from industry reports, government databases, and analyst publications, then calculates your addressable market using both top-down and bottom-up approaches. On aidowith.me, the Pitch Deck route covers 13 steps in about 2 hours 30 minutes. The market sizing section takes roughly 30 to 40 minutes. You'll walk out with a slide-ready table showing TAM, SAM, and SOM with source citations, plus a methodology note explaining the calculation. Most founders spend 2 to 3 days building this slide. This route gets you a defensible first version in under an hour. The route also generates a sensitivity analysis showing how your SOM estimate changes if your market share assumptions shift by plus or minus 10%. This prepares you for the inevitable investor follow-up question.

The Problem and the Fix
Without a route
- An investor asked how you calculated your $2B TAM, and you couldn't explain the methodology on the spot
- You spent 2 days searching for market data and ended up with numbers from a 3-year-old report that no longer applied
- Your SAM and SOM numbers were copy-pasted from a competitor's deck, and a due diligence analyst noticed
With aidowith.me
- Get TAM, SAM, and SOM estimates calculated using both top-down and bottom-up approaches
- Receive source citations for every number so you can defend the slide in investor Q&A
- Finish the market sizing section in 30 to 40 minutes with a methodology note included

Questions
AI references industry reports (Gartner, Statista, IBISWorld), government databases (Census, BLS), analyst publications, and company filings. Each number in your TAM/SAM/SOM table includes a source citation. You should verify key figures, especially for niche markets. The route on aidowith.me walks you through each step with specific examples so you can apply this immediately to your real work.
It works, but with caveats. For emerging markets, public data may be limited. AI will use proxy markets and bottom-up calculations to estimate sizing. The methodology note explains the approach, so investors can see your reasoning even when hard data is sparse. The route on aidowith.me walks you through each step with specific examples so you can apply this immediately to your real work.
The route outputs a structured table with TAM, SAM, SOM values and sources. You take this into your slide tool (Google Slides, Keynote, PowerPoint) and style it to match your deck.
