In most organisations, TAM is something created for an investor deck then forgotten. In Decidr, TAM carries a different meaning. It’s part of the organisation’s reasoning layer — a way for AI apps to understand the outer boundary of what’s possible.

TAM expresses pure potential. It’s the widest definition of who you could serve if every barrier disappeared. In a fitness app example, TAM isn’t “users with iPhones in certain markets.” It’s everyone who wants to get fitter. Simple, but powerful.

Inside Decidr, TAM becomes more than a market metric. It becomes a top level signal that helps your agentic apps understand ambition. When your market entities (industries, regions, workflows, organisational sizes and so on) are represented in schema, TAM isn’t a guess. It’s a structured expression of how your organisation perceives the world around it.

This matters because Decidr treats goals as nested layers of possibility, capability and execution. TAM lines up with that top layer — the broadest expression of opportunity. It helps apps reason about what the organisation might one day reach for, even if it isn’t feasible right now.

In a networked organisation, TAM also stops being static. As new capabilities come online, regulations shift or demand patterns evolve, your understanding of the total market can expand or contract. TAM becomes a living object, shaped by your ontology and updated as the world moves.

By framing TAM this way, Decidr turns it into something more useful than a slide in a presentation. It becomes part of your intelligence architecture. It helps reveal blind spots, highlight overlooked segments and clarify the true scope of your opportunity space.

In short, TAM shows possibility. It gives your organisation and its apps a shared sense of the full opportunity landscape — not as a forecast, but as a structured understanding of what could exist if your constraints were removed.
