Short answer

How can I use AI to build a bottom-up market size estimate?

You provide the specific customer counts and segment definitions from your own data. Your AI uses these inputs to calculate your TAM, SAM, and SOM. You get a clear, tiered breakdown of your market potential.

The outcomes

Where your data lands.

The AI processes your raw segment counts into these four specific results.

TAM

Total Addressable Market

The AI calculates the total market ceiling based on every possible customer in your defined universe.

SAM

Serviceable Addressable Market

The AI narrows the total market down to the specific segment your product can actually reach.

SOM

Serviceable Obtainable Market

The AI estimates the portion of the SAM you can realistically capture with your current resources.

HUMAN

Strategic review

You check the final numbers to ensure the underlying segment assumptions match your business reality.

The workflow

What your AI does when the data arrives.

The AI handles the heavy lifting of the bottom-up math.

  1. Read segment data

    Your AI pulls the specific customer counts and segment definitions from your provided files.

  2. Run calculations

    The AI applies bottom-up logic to your data to derive the three market tiers.

    calculate_tam_base

  3. Organize tiers

    The AI structures the TAM, SAM, and SOM into a logical hierarchy.

  4. Prepare output

    The AI formats the final market size results for your use.

FAQ

How this task behaves

  • 01

    Can the AI find new market segments for me?

    No. The AI only calculates the size of the segments you provide in your data.

  • 02

    Will the AI edit my original spreadsheets?

    No. The AI only reads the data to perform the calculations; it cannot change your files.

  • 03

    Does it work with any data source?

    It works with any data source your AI client can access, like a CSV or a Google Sheet.

  • 04

    Can I see the math used for the TAM?

    Yes. You can ask your AI to explain the specific logic and formulas it used for the calculation.

  • 05

    Do I need to provide the formulas myself?

    No. The AI uses standard bottom-up logic to process your segment counts automatically.
