Great framing Akhilesh. In my experience it’s the structural assumptions you mentioned — specifically how decisions get made. Most US/UK companies enter DACH assuming the buyer is one person with budget authority. In reality, German B2B purchases involve more stakeholders, more formal evaluation, and longer internal sign-off processes. So you get CAC inflation not because the marketing is wrong, but because the funnel was designed for a 30-day close and the market needs 90. The fix isn’t better ads — it’s restructuring the entire lead-to-close process for the local buying culture before you spend a euro on campaigns.
