Substack tells you opens and clicks. StackIntel maps every paid conversion and cancellation back to a specific post — so you know what's earning, what's churning, and what to write next.
You're a writer running a real business. Surface-level analytics aren't enough — you need to know which posts pay rent and which ones quietly cost you subscribers.
No integrations to set up. No code to install. Five minutes of exports and we'll handle the rest.
Substack subscribers, Stripe payments, and your post list. All exportable in under five minutes from tools you already use.
Each conversion is attributed to the most recent post before upgrade. Each cancellation is mapped to the post that preceded it. We surface the patterns.
A single PDF covering revenue, top performers, churn drivers, format insights, and concrete recommendations. Yours to keep.
No vanity metrics, no padded charts. Just the data you need to decide what to write next — and what to stop writing.
