How to choose your first overseas market

The most expensive decision in cross-border expansion is the first one, and it is usually made in a meeting that lasts forty minutes. Someone says the TAM in Germany is big. Someone else says a friend did well in Mexico. A market gets picked, and eighteen months later the company has learned an enormous amount about a country it should never have entered.

The problem is not that teams lack data. It is that they collect the wrong data — market size, GDP growth, smartphone penetration — none of which tells you whether your product can be sold there by your team at a price that works.

Here is the filter we use instead. It takes about a week.

Filter 1: Can you serve it without rebuilding the product?

Before anything else, list what would have to change in your product for a customer in this market to complete a purchase and get value.

Be specific and be brutal:

• Does the checkout accept the payment methods people actually use? In Germany that means bank transfer and direct debit. In the Netherlands it means iDEAL. In Brazil it means Pix and instalments. A market where your existing payment stack fails is not a market — it is a project.
• Does the product work in the local language, or merely display in it? Translated marketing copy on an English-only product is a bounce.
• Are there regulatory requirements that gate entry entirely? Data residency, licensing, local entity requirements.

If the answer to any of these is a six-month engineering programme, the market is not your first market. It might be your third.

Filter 2: Is there an existing, findable demand signal?

You are not creating a category. You are looking for people already trying to solve the problem, badly.

Cheap ways to find out:

• Search volume for the problem, in the local language, not the English keyword translated. Native speakers do not search the way translation tools think they do.
• Existing competitors. Zero competitors is a red flag, not an opportunity. It usually means someone tried and the unit economics did not work.
• Marketplaces and forums. If people are buying an inferior version of your product on a local marketplace, that is demand you can measure.

Filter 3: What does customer acquisition actually cost there?

This is the filter that kills most enthusiasm, which is exactly why it goes third and not last.

Do not model this. Go and buy some traffic. A few hundred dollars of paid search or paid social against a landing page in the local language will tell you more about CAC than a quarter of desk research. You are not looking for conversions yet — you are looking for cost per qualified click, and whether the number is within an order of magnitude of your home market.

Two things surprise people here:

1. CPCs are often higher, not lower, in "cheaper" markets. Advertiser competition, not GDP, sets the price. A market with a small pool of advertisers and a large pool of buyers can be brutal.
2. You have no brand. Your home-market conversion rate is partly a brand effect you cannot see. Assume the new market converts worse and be pleasantly surprised.

Filter 4: Can someone on your team wake up in that timezone?

The unglamorous one. Cross-border operations fail on coverage more often than on strategy.

If a customer in Jakarta writes to support at 10am local time, when do they hear back? If your answer involves the word "eventually," the market will churn faster than you can acquire it. Every market you enter is a commitment to being awake for it — either by hiring there, or by structuring your team around it, or by narrowing the product until it genuinely needs no support.

Pick a market where you can honestly answer this question today.

What this looks like in practice

Run all four filters against three candidate markets at once. Score each filter red, amber, or green — no numbers, no weighted matrices, they only launder your existing bias.

The market you enter should be green on filters 1 and 4, and at worst amber on 2 and 3. A market that is green on 2 and 3 but red on 4 is the classic trap: obvious demand, obvious economics, and no one to answer the phone.

The first market is not the biggest opportunity. It is the one where you can build a repeatable playbook cheaply enough that the second market costs half as much.
