How does this skill calculate TAM?

It uses a dual-triangulation approach, combining top-down industry report data with bottom-up unit economics (total customers × average price) to ensure cross-validated accuracy.

Does it provide growth projections?

Yes, the skill generates a 2-3 year forecast for TAM, SAM, and SOM, identifying key growth drivers and emerging market trends that could impact the trajectory.

Can I use my own internal data or research?

Yes, you can provide industry reports, financial data, or competitor information as input, and the skill will analyze them to refine the market estimates.

What is the difference between SAM and SOM in this framework?

SAM (Serviceable Addressable Market) is the portion of the market your product can realistically reach, while SOM (Serviceable Obtainable Market) is the specific share you expect to capture in the next 1-3 years.
