Start GTM in the USA in the segment where one U.S. software vendor already owns the buyer, not in the segment with the biggest market. For an AI or software company outside North America, the right first segment is the one where a single platform decides who gets through the door, because that is where one partnership can open many accounts at once.
The August 2026 Epic user conference shows why. Epic, the dominant U.S. electronic health record vendor, said it is taking on ERP, clinical trials management and AI functions that third-party vendors have historically provided (Advisory Board, August 26, 2026). Healthcare is one example, but the pattern holds in every U.S. segment: a few platforms control the buyer, and they decide which AI and software companies reach it.
Why picking the biggest U.S. segment fails
The usual plan is to size the market, pick the largest segment and hire a United States sales team to chase it. That plan fails for AI and software companies outside North America for three reasons. Large segments are crowded, so a new entrant competes on price before it has references. Buyers in regulated or platform-dominated segments ask for security reviews and local proof that a first-time entrant cannot supply. And a new United States hire needs months to build trust that a partner already has. Direct sales still works as a bridge tactic, and our comparison of strategic partnering vs. direct sales shows when each fits, but it is a poor way to choose a segment.
Why a partner-anchored segment works
When one vendor owns the buyer, a single yes opens a whole installed base. That is why the first segment should be chosen by who controls access, not by total market size. A referral, integration or white-label partnership with that vendor puts your product in front of accounts that would otherwise take years to reach. If you are weighing who should help you make that approach, start with our guide to who can help with partnerships in North America, and if the vendor is bigger than you, see which software qualifies for a white-label partnership with a larger U.S. vendor.
Three tests for your first U.S. segment
Run every candidate segment through these tests and keep the one that passes the most.
Gatekeeper test. Can you name the one or two U.S. software vendors that control buyer access in the segment? If you cannot, the segment is too fragmented for a first move.
Fit test. Does your product make that vendor’s platform more valuable, or does it replace a feature the vendor may build itself? Complement beats overlap, though overlap can still become a white-label deal.
Proof test. Can you meet the segment’s minimum security and compliance bar within a normal deal cycle? SOC 2, for example, can be started during a roughly six-month negotiation, so it should not block you from choosing a segment.
How North America Entry delivers
We pick the segment with the client and then build the partnership channel into it. One client grew from $25K to $3M in ARR with 90% of revenue coming from partners. Another signed six Tier One and two white-label partnerships in 1.9 years, and eight M&A cycles were triggered across our work. Partner revenue contributions across four organizations were 90%, 65%, 37% and 15%. You can see more on our value to AI and software companies page, and the broader approach is in our guide to who can help with GTM in the USA for AI and software companies.
Frequently asked questions
Should an AI or software company pick the largest U.S. segment first for GTM in the USA?
Usually not. The largest segment also has the most competitors and the least reason to trust a company outside North America. A smaller segment where one United States software vendor already owns the buyer relationship is faster to enter and easier to prove.
How many U.S. segments should an AI or software company test at once?
One. A single segment lets the company learn what sells, what security reviews ask for, and which partner can carry the deal before it spreads effort across several.
What if the leading U.S. vendor in a segment is also a competitor?
Then treat that vendor as the first partner to approach, not the one to avoid. A white-label or integration partnership can turn the platform that might absorb a feature into the channel that sells it.
