A large problem is not automatically an accessible opportunity. You need a customer group you can reach, a reason it will choose you and an economic opportunity consistent with your ambition. Market selection can matter more than working harder on the current plan.
Focus makes learning transferable: similar customers help product, sales and delivery improve together. A narrow entry point can support a large company if it opens a credible expansion path. A profitable niche can also be the intended destination; the financing model must fit that choice.
Use this principle when: choosing an initial segment, accepting a large unusual customer or considering another sector, country or product line.
What to do
- Compare a few plausible entry markets on customer urgency, access, feasibility, competition, economics and timing. A fatal weakness cannot be averaged away by a high total score.
- Choose the primary customer and use case. State which attractive requests you will decline and show where team capacity actually goes. A strategy with no refusals has not allocated scarce resources.
- For your intended scale, explain the route beyond the entry market. Identify what transfers: distribution, product, qualification, reputation or delivery. List what must be proved again.
Evidence that changes the decision
Proceed: you can reach suitable customers, their responses support the proposition and serving them improves a common core. The opportunity fits the founders’ goals and the capital being raised.
Change the plan: every sale requires a different product or buying process, the timing depends on developments beyond your reach, or the entry market cannot support the intended outcome. Explore an alternative with bounded capacity.
Stop this route: there is no credible way to reach, serve or earn enough from the market within the resources you can assemble.
Where founders misapply it
Focus is a current allocation choice, not a promise to ignore evidence. Revisit it when the underlying assumptions change. Domain experience can improve access and judgement, but familiarity is not proof of opportunity. Research associates relevant industry experience with success; it does not require a particular founder age or background. [4]
Porter’s trade-offs and activity fit explain the strategic mechanism. Ecosystem research also shows why the readiness of complementary technologies matters. [10][8]
Connect it to the whole venture
Use BOM’s Mission building block to make the founders’ intended contribution and boundaries explicit. Then assess the chosen position against the Market building block: competitors, buying cycles, wider trends and the ecosystem. Keep one primary value proposition clear; describe materially different propositions separately so their customers, costs and assumptions do not blur together. [18]
Next decision: name one opportunity you will refuse and one observation that would justify revisiting that refusal.
