Automated exit-interview tool for silent SaaS churn

What to build

An automated churn-exit-intelligence tool for solo and small-team SaaS founders: it listens to Stripe (or other billing) webhooks to detect cancellations in real time, immediately triggers an AI-driven exit survey or conversational interview by email, and rolls responses up into a dashboard that clusters cancellation reasons into themes and trends over time.

Small SaaS founders currently get zero structured signal when a customer cancels, so churn stays a mystery instead of a fixable, categorized problem; pairing billing-webhook detection with an AI exit interview turns that silence into trend-visible data.

Demand

Solo and small-team SaaS founders are the ones feeling this gap most acutely, since they lack the CS teams or budget that larger companies use to run manual exit interviews, and billing/AI tooling is now cheap enough that a single builder can automate the whole loop.

  Post framing: "The hardest part of churn isn't losing the customer.. It's not knowing why. You lose them silently. No email. No survey. Just..." — articulates the exact pain point of silent, undiagnosed churn for small SaaS operators.

Stack

• Stripe API / webhooks
• OpenAI API or Claude API (survey generation + theme summarization)
• Next.js
• Supabase (Postgres + auth)
• Resend or Postmark (transactional email for the exit survey)
• Vercel (hosting)

Solo + AI difficulty

The billing-webhook listener and a basic templated exit-survey email are straightforward and buildable in a few days; the harder parts are designing an AI exit interview that actually gets people to respond honestly and building reliable theme-clustering across free-text answers into a trend dashboard — realistic time-to-MVP is roughly 2-3 weeks for a solo builder using AI-assisted coding.

Entry threshold

Low barrier: one developer can build an MVP with Stripe webhook integration, an email/survey flow, and LLM-based summarization of free-text responses within a couple of weeks; main cost is distribution and getting founders to install another tool.

Counter-signals & risks

• Exit surveys historically suffer from very low response rates, especially when fully automated and impersonal, which limits the data quality and statistical significance of resulting themes.

• Larger existing customer feedback, retention, and billing-analytics platforms could add automated exit surveys and churn-theme dashboards as a feature, eroding the niche for a standalone small-founder tool.

• Solo and small-team founders tend to be highly price-sensitive and already stretched across many tools, so willingness to pay for yet another point solution is uncertain.
