Why European Founders Who Think They Don't Have PMF Might Have PMF on a Different Timeline

The PMF test most European founders are running is calibrated to the wrong benchmark. If you're comparing yourself to American hypergrowth — 3x annual revenue, exponential user curves, viral adoption — European enterprise startups will perpetually appear to be underperforming. A retention curve that flattens after month 12 in a business with 18-month enterprise contracts isn't weak PMF — it's exactly the right shape for that contract structure. The question is never 'do I have PMF by US consumer standards?' It's 'have I identified the right PMF signal for my specific market category, sales cycle, and buyer commitment structure?' Those are different questions. They have different answers.
