Every year, well-funded international brands enter the US market with strong products, solid reputations in their home markets, and a strategy built on assumptions. Some of those assumptions are reasonable. Most are expensive.
After spending 25 years working across Brazil, the UK, and the US — and now running a market intelligence platform that helps agencies advise brands on exactly this question — I've seen the same patterns repeat. The brands that succeed aren't necessarily smarter or better funded. They're the ones who tested their assumptions before committing capital.
Here are the five assumptions that cost brands the most — and what agencies can do to protect their clients.
1. "Our product already sells well at home, so the US market is just distribution."
This is the most common and most dangerous assumption. A product that's a market leader in Germany, Brazil, or Japan doesn't automatically translate to the US. The competitive set is completely different. Consumer expectations are different. Even shelf placement norms are different.
In the US CPG market alone, over 30,000 new products launch every year. The average American grocery store carries 30,000–50,000 SKUs. Your client's product isn't competing against the same three competitors they face at home — it's competing against an ocean of options, private label brands that didn't exist five years ago, and DTC brands with aggressive digital marketing budgets.
What agencies should do: Run a competitive landscape analysis before any go-to-market work. Map not just direct competitors, but the substitutes, the emerging DTC brands, and the private-label alternatives. Understand where white space actually exists — not where the brand thinks it exists.
2. "We can figure out the regulatory landscape as we go."
US regulatory requirements for consumer products — especially food, beverage, supplements, and personal care — are not something you figure out after you've committed to a launch timeline. FDA labeling requirements, state-by-state variations, Prop 65 in California, USDA organic certification, and the constantly evolving clean-label expectations from retailers can each individually delay a launch by 3–6 months.
I've watched brands invest six figures in packaging design only to discover their ingredient claims aren't permitted under US labeling rules. I've seen launch timelines pushed back a full year because a product needed reformulation to meet retailer requirements.
What agencies should do: Include a regulatory and compliance snapshot in every market entry engagement. Even if your agency doesn't specialize in regulatory work, flagging the key requirements early — and connecting clients with the right specialists — is the difference between a 12-month launch and a 24-month one.
3. "Amazon is our channel strategy."
Amazon is a channel, not a strategy. It's an important one — roughly 40% of US e-commerce happens on Amazon — but brands that treat it as their entire US market approach are leaving enormous value on the table and building on someone else's platform.
The US retail landscape is more fragmented and more complex than most international brands realize. Walmart, Target, Costco, Kroger, Whole Foods, regional chains, independent specialty retailers, foodservice, and DTC each have different buyer expectations, margin structures, and discovery mechanisms. A brand that's Amazon-only has no broker relationships, no retail shelf presence, and no foodservice pipeline.
More importantly, Amazon is becoming increasingly expensive for brands. Advertising costs on the platform have risen 30% year over year, and the algorithm rewards brands with established review velocity — meaning new entrants are at a structural disadvantage.
What agencies should do: Map the full distribution channel landscape for the client's category. Include broker and distributor requirements, retailer category review timelines, and a phased channel strategy that doesn't put all revenue in one basket. A distribution channel map should be a deliverable in every expansion engagement.
4. "Our brand story is universal."
Heritage, craftsmanship, and origin stories that resonate powerfully in Europe or Latin America often fall flat in the US market. American consumers — particularly Gen Z and Millennials — respond to different value propositions: functional benefits, transparency, sustainability credentials, founder stories with a personal hook, and social proof.
A Brazilian açaí brand can't lead with "traditional Amazonian superfruit" and expect the same response they'd get in São Paulo. In the US, the conversation is about antioxidant levels, sugar content, organic certification, and whether it fits into a morning smoothie routine. The origin story matters, but it's supporting cast — not the headline.
What agencies should do: Conduct brand positioning research specifically for the US audience. This doesn't have to be a six-month ethnography. AI virtual focus groups can test messaging, packaging concepts, and positioning against US consumer personas in days — and deliver segment-level reactions that inform creative strategy.
5. "We'll invest in research after we launch."
This is the assumption that enables all the others. Brands tell themselves that market research is a Phase 2 investment — something they'll do once they have initial traction. But the brands that wait for post-launch data to inform strategy are spending 3–5x more to fix problems that research would have prevented.
A structured market expansion assessment takes 14 days and can identify category white space, regulatory red flags, distribution complexity, and competitive threats before a dollar is spent on packaging, logistics, or marketing. The alternative is learning those lessons through failed launches, retailer rejections, and capital depletion.
What agencies should do: Make research the first billable deliverable in every expansion engagement. Position it not as a cost, but as insurance — a structured, data-driven answer to the question: "Should we enter this market, and if so, how?" The EVC (Expansion Viability Coefficient) framework gives clients a single score and a clear recommendation. It's a conversation-ender for the "should we or shouldn't we" debate.
The bottom line
Smart brands don't fail because they have bad products. They fail because they make assumptions instead of investments. And agencies that help their clients test assumptions before committing capital aren't just providing a service — they're building the kind of trust that turns a single engagement into a long-term advisory relationship.
Research isn't the phase after strategy. It's the phase that makes strategy possible.
