Short answer: neither. Architecture first, rep second, office third. The order most foreign vendors run is exactly inverted, which is why the office shows up before the first close.
A US rep cannot close inside broken materials. The rep enters discovery with a translated deck, a German proof set, and a price presentation the US buyer cannot evaluate, and the deal stalls at the same beats every time. The rep reports up that "Americans don't get our product" and quits at twelve to eighteen months. The replacement rep reports the same thing. The cost of two rep cycles inside broken sales system runs $400k-$700k loaded per loop. The office decision arrives during cycle two and adds a real estate line on top of the same broken system. None of those moves changed the architecture.
Per IMAP German Mid-Cap M&A 2026 and White & Case M&A Explorer 2026, foreign vendors that rebuild architecture before hiring close first deals inside two quarters at a 2-4x conversion rate versus vendors that hire first. The rep is more productive inside a working system. The office signal lands harder when revenue is already in the door. The sequence is structural, not preferential.
Office before rep, before architecture, is a vanity signal. It looks committed in a board deck. It costs $300k-$1.2M per year in fixed overhead before the first close lands. The US office that is not closing in year one is usually not a market problem. It is a sequence problem. Per US BEA FDI inflows 2025, the inflow is at multi-year highs and the offices opening fastest are the ones built after architecture rather than before.
Buyer-language pattern. The company works at home. The US buyer still asks what category it belongs in, why the proof is relevant here, and what the next low-risk step should be.

A Market-Entry Marketing Sprint rebuilds the US-facing architecture in six to ten weeks. The rep hire follows. A Cross-Border Marketing Build runs three to six months and is the standard shape for committed US scale when the rep and the architecture are built in parallel. A Global Marketing Partnership is monthly retainer with a twelve-month minimum. Commercial terms are set after fit and scope are clear. No public price bands are published.
