Nail your TAM/SAM/SOM, revenue model, and ask slide. AI runs the numbers while you tell your story.

13 steps ~2h 30min For founders & managers Free

A seed round deck with market sizing and AI takes about 2.5 hours to build when you follow a structured route. The hardest part of any seed deck is the market sizing slide. AI calculates your Total Addressable Market, Serviceable Addressable Market, and Serviceable Obtainable Market using industry data, competitor revenues, and your pricing model. On aidowith.me, the Pitch Deck route covers 13 steps to produce a full investor deck with market sizing, competitive landscape, revenue projections, and team slides. You'll build a bottom-up market model (not just a top-down guess), which is what investors at the seed stage want to see. Decks with bottom-up market sizing receive 35% more follow-up meetings, according to DocSend pitch deck data. The output includes 12 to 15 slides ready for Google Slides or PowerPoint.

The Problem and the Fix

Without a route

  • Your TAM slide says '$50B market' but investors ask how you calculated it, and you can't explain
  • Building a bottom-up market model takes 8 hours of spreadsheet work with uncertain assumptions
  • The deck has 30 slides because you're not sure which information investors care about at seed stage

With aidowith.me

  • AI builds a bottom-up TAM/SAM/SOM model from industry data, competitor revenue, and your pricing
  • The route produces a focused 12 to 15 slide deck with only what seed investors want to see
  • Every assumption in the market sizing is documented, so you can answer investor questions on the spot

Questions

The deck covers 12 to 15 slides: problem, solution, market sizing (TAM/SAM/SOM), business model, traction, competitive landscape, team, revenue projections, use of funds, and the ask. Market sizing includes a bottom-up model with documented assumptions.

Seed investors don't trust top-down estimates like 'the market is $50B.' They want to see how many customers you can reach, at what price, and in what timeframe. A bottom-up model shows you've done the math and think like an operator, not a dreamer.

Yes, with adjustments. Pre-seed decks focus more on the problem and team, less on traction. Series A decks need detailed metrics and growth data. The route lets you customize the emphasis per stage. The market sizing framework works at any stage.
