Silent Churn Detector: Predictive Retention for SaaS

If an entrepreneur "adopted" this product today, here's the realistic math.

Fermi summary

Land 100 SaaS customers at $60/mo and you're at $72k ARR - but Baremetrics and ProfitWell already own this shelf, so your realistic odds of getting there in year one are about 14%, and year-one expected value is negative after setup costs.

Market size (TAM)

$38.0M

~12,000 SMB/mid-market SaaS companies ($500k-$10M ARR) with enough paying customers to care about churn tooling × $3,200/yr average spend on retention analytics

Investment to production

$28k

Dev: $14k for Stripe/Segment/CSV integrations + ML scoring pipeline. Infra: $3k for year-one hosting and AI API costs. Marketing: $8k for Ap

Go-to-market motion

Cold outbound via Apollo/LinkedIn to SaaS founders and heads of growth → 20 demos/month → 3 closes/month at $69-199/mo, with a secondary bet on Stripe App Marketplace listing for inbound discovery.

Key risks

Baremetrics, ProfitWell/Paddle, and Stripe's native churn dashboards already cover 80% of what SMB SaaS founders need for free or near-free - the differentiation bar is higher than it looks
Churn ML predictions require 6-12 months of customer-specific historical data to be accurate; early customers are essentially paying to train the model on their data with no validated proof it works yet
Integration complexity (product DB + billing + support tickets must all be wired up) creates a 2-4 week onboarding slog that kills trial conversion for a self-serve motion
