A r/SaaS founder who posted three months ago about churn driven by users saying 'cool product, but I'll build this myself with Claude in a weekend' returned with results (91 upvotes, 47 comments), reporting that roughly 70% of churned users gave that reason and that a month of fighting the objection did not work — the follow-up describes what changed once they stopped. This is the clearest practitioner-level datapoint yet that agentic coding is not just changing how software gets built but actively repricing the floor of what a small SaaS can charge for.
