Short answer: the competitor rebuilt the US-facing register and the firm did not. Same engineering. Different document. The procurement officer is reading two different stories.
CUT.
US procurement evaluates RFP responses on a structural template that grew out of US federal acquisition practice and spread into private-sector procurement. Executive summary on page one. Outcome claim with named US peer. Quantified result. Security posture. Pricing in USD. US warranty and SLA language. US service entity. Engineering and certifications sit in supporting appendices. The procurement officer scores against the template. A response that matches scores high. A response that buries the executive summary on page nine scores low. The same engineering. Two different scores. Per FAR Part 15 evaluation guidance, source selection scoring rewards readability and outcome clarity, not technical depth alone.
The German competitor that is winning every US RFP figured this out and rewrote the RFP template. Their engineering is the same. Their certification stack is similar. Their case studies are still mostly European. What changed is the document order, the cover note, and the executive summary. The firm's response is still a translated home-market response. The procurement officer reads thirty responses a quarter and rewards the one that respects the officer's scoring sheet. IMAP German Mid-Cap M&A 2026 notes the same pattern in DACH-to-US deal awards: register-aligned responses win at 3-5x the rate of capability-led responses.
Gartner forecasts 90% of B2B purchases will involve AI agents by 2028 and Forrester projects 1 in 5 B2B sellers facing an AI buyer-agent by end-2026. The AI evaluator applies the same scoring template, with less mercy for buried executive summaries. The competitor's response will keep winning. The firm's response will keep losing.
"Hardest part wasn't language or paperwork, it was realizing your 'obvious' value prop doesn't land the same way. The surprises are usually distribution and trust. Who people buy from, what proof they need, and how long they take to decide all changes."

A Market Entry Sprint includes RFP-response template rebuild as a deliverable inside the six-to-ten-week scope. The output is a working US-format response with the executive summary, peer set, outcome claim, security posture, and pricing in USD. A Cross-Border Build runs three to six months for multi-channel US presence including the RFP function. A Group Partnership is monthly retainer with a twelve-month minimum. Pricing is confirmed in discovery, not on the public site.
