Entering the United States is not one market-entry decision. It is a sequence of decisions about which problem, buyer, industry, location and route to market deserve your attention first. The most common strategic error is to treat the size of the US economy as evidence that a product has an immediately reachable American customer.
An international company with paying customers elsewhere may already know that its product works. It still needs to establish how a specific US customer recognizes the problem, selects vendors and approves a purchase. A focused first segment makes those questions answerable.
International reach is increasing. Customer selection still matters.
Stripe Atlas reported in its December 2025 year in review that the median startup in its 2025 cohort sold to customers in two countries during its first six months. Across its 2017 to 2024 cohorts, the median was one country. That is evidence of increasing early international reach within the Atlas population. It is not proof that those startups succeeded in the US, or that international expansion is equally straightforward for enterprise software, industrial technology and regulated products. See Stripe Atlas’s original analysis.
The practical implication is straightforward: the ability to operate across borders is becoming less distinctive than choosing which customers to pursue and demonstrating why they should change suppliers.
Buyer selection
Use this sequence to compare segments before building a larger prospect list.
1. Start with buying urgency rather than market size
A total addressable market is useful for understanding the long-term opportunity. It is less useful when deciding who should receive the next 20 outreach messages. Begin with a narrowly defined group of companies facing an identifiable operating problem. Ask whether that problem has an owner, a current workaround and a reason it might become important this quarter.
- Urgency: What operational event makes the buyer search for an alternative now?
- Consequence: What happens if the customer retains its current workflow or vendor?
- Ownership: Which executive, team or budget holder experiences the problem directly?
- Access: Can the company reach decision-makers through a realistic sales or partner route?
For a cybersecurity vendor, the relevant entry segment might be a class of infrastructure operators with recurring third-party security reviews. For an industrial automation company, it may be manufacturers with a particular production process and an established maintenance channel. These are hypotheses to validate, not claims about demand in either sector.
2. Use existing customer evidence to find a sharper segment
A helpful parallel comes from Superhuman, the email software company. Founder Rahul Vohra explained that, in an early user survey, only 22% of respondents said they would be very disappointed if the product disappeared. The team studied users who valued the product most, used their responses to focus product development and repeated the survey. After three quarters, the reported proportion reached 58%. The percentages are a product research result, not a US market-entry outcome. Read Vohra’s original account.
The transferable lesson is the discipline of learning from strongly engaged users instead of assuming everyone is equally valuable. International companies can apply that discipline before US expansion: find the home-market customers with the clearest outcomes, then investigate whether analogous buyers in the US share the need, buying process and implementation constraints.
3. Compare segments on four dimensions
Problem specificity
Write the buyer’s problem without using your own product category. “Need AI” is not a problem definition. “Reviewing equipment records takes three people across four systems” is closer to something a buyer could verify. If the definition is vague, narrow the segment or conduct discovery before investing in broader outreach.
Purchase pathway
Identify the initiator, technical reviewer, decision-maker and procurement owner. Some small customers can test new products quickly. Others need security, legal, financial, integration and operational reviews. A segment may appear attractive in product demonstrations but remain unsuitable for an early commercial launch if the purchase pathway is poorly understood.
Credibility requirements
Ask which proof the buyer will accept: local references, a technical integration, a quantified operational improvement, relevant security documentation, pilot results or a suitable support model. Do not claim credentials or compliance certifications that your company does not hold.
Practical access
Research whether buyer conversations are reachable through direct outbound, industry associations, existing customers, channel partners or sector specialists. A large segment with no identifiable decision-makers may be less attractive than a smaller segment with reachable buyers and clear purchase triggers.
4. Design a small evidence-gathering sprint
Choose two or three plausible segments, then plan a focused discovery sprint rather than building an enormous contact database. For each segment, interview or research a consistent set of buyer roles, document the language they use, and identify the reason they would prioritize or reject a new vendor. Record contradictory evidence rather than editing it away.
- Document a concise ideal customer profile for each segment, including exclusions.
- Choose an explicit buyer hypothesis that can be disproved.
- Create a short account list from real firms fitting the definition, not a mass scraped audience.
- Prepare three discovery questions tied to current workflow, purchase urgency and procurement.
- Review which segment produces the clearest evidence before scaling outreach.
The purpose is not to promise a fixed number of meetings or an immediate sales result. It is to reduce the uncertainty in the next commercial decision.
What the output should look like
At the end of this work, leadership should have one prioritized customer segment, a defensible buyer problem, a clear picture of the purchase pathway, an initial list of target accounts and a next action. Market research that cannot change these decisions is unfinished.
