Intuition
A market entry case is a "should we walk through this door?" question. New country, new product category, new customer segment — the shape is always the same. And the trap is always the same too: candidates fall in love with the size of the opportunity ("it's a $10B market!") and forget to ask whether they can actually win a slice of it, and whether the economics beat just staying put.
A great entry answer treats "don't enter" and "enter differently" as live options, not failures.
Framework
Four stages:
- Is the market attractive? Size, growth rate, profitability (Five Forces), and trends. A big market with terrible economics is a trap.
- Can we win? Our capabilities and advantages vs incumbents, and how they'll react. Do customers have a reason to switch to us?
- What are the economics & entry mode? Investment required, expected returns/payback, and how to enter — build, buy, or partner.
- What are the risks? Regulation, retaliation, cannibalization, execution — and what would change the decision.
Worked Example
A US streaming service weighs entering India. Market: huge and fast-growing but low ARPU and brutal price competition — attractive in size, thin in margin. Can we win? Strong content library, but local players own regional-language content and cricket rights customers crave. Economics: high content-licensing cost, long payback. Mode: partnering with a local telco beats building alone. Recommendation: enter, but via partnership and a low-price, ad-supported tier — and only if cricket/local content can be secured, since that's the make-or-break risk. The "how" carried the answer as much as the "whether."
Pitfalls
- Falling for market size while ignoring whether you can actually capture share.
- Forgetting competitor reaction — incumbents fight back, often with price.
- Recommending "enter" without specifying the entry mode and the conditions that would flip your answer.
