Founders on r/indiehackers consistently report that they know they should interview churned users but never do — the user is gone, the moment is awkward, and there's no system. VoiceOfChurn triggers an automated async voice or text interview (via a short Loom-style prompt or SMS link) at the moment of cancellation, transcribes and categorizes the response, and builds a running churn reason registry that updates every week. Unlike in-app exit surveys with 2% completion rates, a personalized outreach link sent immediately after cancel sees 15–30% response rates in comparable tools.
Micro-SaaS founders with 50–500 active subscribers who are losing 3–8% monthly to churn and don't know why
$29/mo for up to 100 cancellation interviews/month; $79/mo up to 500 — priced against the value of one recovered churned customer
Reddit: Stripe's cancellation flow webhook makes it trivially easy to trigger an immediate outreach the second a subscription is cancelled, and Whisper makes voice transcription essentially free — the infrastructure finally makes this a weekend build.

Stripe webhook fires on cancellation → sends a personalized SMS with a 60-second Loom-style voice recording link → transcribes response → categorizes into 5 buckets (price, missing feature, bug, no longer needed, competitor) → emails founder a weekly digest.
LLM classifies open-ended responses into actionable churn categories and surfaces the single highest-frequency fixable reason each week as a product recommendation.
Deliverability and response rates depend on the personal feel of the outreach — if it reads as automated spam, completion rates collapse and founders lose faith in the tool within the first month.
Likely buyers are founders, operators, and small teams with a recurring business process. Start with Micro-SaaS founders with 50–500 active subscribers who are losing 3–8% monthly to churn and don't know why and validate whether this can replace a spreadsheet, manual review, or consultant workflow.
Find the first 10 users by searching for recent complaints around "SaaS churn" in Reddit, developer communities, GitHub issues, and niche Slack or Discord groups. Offer a concierge version first: manually solve the workflow for a few users, then automate only the repeated steps.
