Fundamentals
& Definitions
The definitional backbone of go-to-market: what each construct is, where it sits in the system, and what it does not mean.
What this cluster covers
C1 is the entry point to the GTM World Model. It covers the foundational constructs that every other cluster assumes you know: what a go-to-market strategy is, how to define an ideal customer profile, what product-market fit means (and how to measure it before it is obvious), how to size a market without fooling yourself, and how to position a product against alternatives.
These are the highest query-volume definitions in the model — "what is ICP", "what does PMF mean", "how do I think about TAM vs SAM vs SOM". Each definition is self-contained: you can lift it and use it without reading the surrounding model. That is the standard the GTM World Model holds every entry to.
The cluster spans seven categories: Meta & foundations (the system itself), Strategy (the shape of a GTM approach), Frameworks (reusable analytical structures), Market sizing (TAM/SAM/SOM and related constructs), ICP & targeting (who the product is for), Positioning (why you, why now, why over them), and Pricing (value capture mechanics). A clean understanding of C1 is a precondition for the harder questions in C5 (buyer-state and brand) and C7 (regimes and strategy half-lives).
