The founder shipped a marketplace MVP in Bubble in 6 weeks, validated it, and grew. At ~2,000 daily users, workflow execution times crossed 6 seconds on core actions and the per-capacity-unit pricing hit $529/mo. They rebuilt the backend in 11 weeks while Bubble ran the front. Post-migration, the same actions ran in 380ms and infra cost dropped to $190/mo. Bubble did its job perfectly: it proved the idea. The mistake was pretending it could be the permanent home.
