The assumptions that kill your international expansion before it launches

I've had the pleasure to drive many international expansion programmes throughout my 3 decades in B2B SaaS marketing. It is without a doubt one of my favourite strategic endeavours and I'd like to share some key insights I've learned along the way.

When it goes right, it’s usually when all assumptions are laid bare right from the start: deciding which market to enter, performing in-depth competitive intelligence, analysing the product offering against the local market, and working through a multitude of other milestones.

But let's face it, the journey is not always linear, or even logical. Decisions to enter a new market are sometimes made for the wrong reasons and don't always get validated properly. Before you know it, a new Regional VP is in place, and straight away, they want qualified leads. And just like that, you’ve put tactics ahead of strategy, yet again.

So how can you make sure you have the right foundations in place before launching across a new pond?

To start with, remember that international expansion goes beyond go-to-market activities. Some companies approach a new market the way they approach a new campaign: same offer, same positioning, same playbook. Simply translated. Occasionally localised. Rarely rebuilt.

This is completely understandable, almost logical. If your GTM strategy works in the UK or the US, it's natural to assume it will travel. After all, you've validated the product. You have testimonials from great customers. You know what marketing campaigns deliver, and which ones can sink your budget down the drain.

But what you haven't validated is whether any of that translates in the new market. And I don’t mean translation as a language exercise. The real issue is anchored in all those assumptions that rarely survive first contact with the local audience.

Here are the top 3 assumptions I encounter time and time again.

Assumption 1: "Our ICP looks the same here."

The firmographic profile might match (not always). But the buyer is likely to be different. In France, for instance, decision-making authority is often more centralised than British or American companies expect. Procurement cycles are longer. Relationship building precedes commercial conversations in ways that can feel opaque to teams used to a more transactional sales culture. The person with the title you're targeting may not be the person with the influence.

Assumption 2: "Our differentiation translates well."

Your positioning was built to land in a specific competitive context, against specific alternatives, with a specific language that resonates with buyers who think in a specific way. When you change the market, the competitive set tends to shift. Your prospects’ alternatives may be different. The language that signals credibility changes. What sounds authoritative in one market can sound arrogant in another. What feels reassuringly straightforward in one culture can feel condescending in another.

Assumption 3: "The sales cycle will be similar."

That's rarely the case. Culture shapes procurement. It shapes who needs to be in the room, how many meetings it takes before a commercial conversation is appropriate, what role references and relationships play, and how risk is perceived and managed. Projecting your domestic sales cycle onto a new market might help you build a pipeline, but it won't help you convert it to revenue.

So how do you avoid assumptions getting in the way of GTM success, without analysis paralysis setting in? 

Well, it starts with rigorous market validation. Before you commit headcount and budget to a new market, you need to stress-test your assumptions, systematically and honestly.

This is where AI can earn its place in the process: not as a strategy builder, but as a validation accelerator. Performing competitive scanning across a new market, surfacing how native buyers talk about the problems you solve, checking your messaging against locally-produced content… All of this used to take weeks of research. AI can now speed up this stage significantly.

But AI can only tell you what's already out there. It can't tell you what it means for your specific positioning and product, or for the sequencing decisions you need to make. That requires judgment, a human strength that is more critical now than ever.

Choosing which geography to enter next, with what resourcing model, is a judgment call that sit at the intersection of commercial strategy, organisational capacity and risk appetite. I've seen companies launch into a new market with a brilliant local hire and then systematically undermine them with slow internal approvals and poorly localised collateral. And it’s even worse when leadership treats the expansion as a side project until the numbers demand attention.

A well-built international expansion is not a scaled-up local one. It's built from scratch, with fresh eyes on what the market requires, what the buyer needs to hear, and what the organisation is capable of delivering locally.

That means:

• challenging your ICP assumptions before you hire

• testing your positioning in the language of the market

• designing a sales process that fits the culture

And it means having someone in the room who has done this before. Someone who can bridge the gap between the plan and the reality, and who can deliver expansion success and positive commercial outcomes at every stage.
