TAIM stands for Total Addressable In-Market. What does TAIM describe?

• A. The total commercial opportunity right now
• B. The potential opportunity over the next five years
• C. The total marketing qualified leads
• D. The minimum viable market for a new product

Answer: (A)

TAIM is about the revenue you could capture today within the market that is currently in play. It describes the total commercial opportunity right now—everything you could potentially sell to current, in-market customers if you achieved full penetration. The emphasis is on immediacy and existing demand, not future expansion or speculative opportunity.

This is why it fits best: it focuses on the real, present market you can access, rather than a horizon of growth over the next five years or a funnel metric like leads. It also isn’t about the smallest viable market for testing a product. That concept refers to the minimal market size needed to support a business idea, not the entire in-market opportunity available at the moment.
