Free diagnosis today. Paid recovery post-validation.

Four leaks. One platform. Ships in stages.

The Leak Detector is live and free today. The paid modules — Dunning, Trial Optimizer, Cancel Flows + Win-Back — ship once we've validated that founders actually want them. Reserve launch pricing below if you want the full stack at founding-customer rates.

Revenue Leak Detector

Free today

Stripe Payments CSV → diagnosis. Flags failed payments, expiring cards, abandoned trials, and silent cancellations across a 90-day window, with per-decline-code recoverability estimates.

Mechanism: Papa Parse + DuckDB-WASM in your browser. Row-level data never leaves your device — only aggregate totals are transmitted when you save the report.

Dunning

$49 Entry · reserve now

Branded retry emails on invoice.payment_failed. 3-step sequence over 14 days. Sends from billing.yourdomain.com, not from Paritum.

Mechanism: typically adds ~20 percentage points on top of Stripe's ~57% native recovery baseline. Actual rate depends on your decline-code mix.

Trial Optimizer

$99 Bundle · reserve now

Nudge users toward paid on customer.subscription.trial_will_end. Configurable reminder cadence, activity-gated branching, payment-update link.

Mechanism: event-keyed sequences fire N days before trial end. No “usage scoring” — we only react to events Stripe emits.

Cancel Flows + Win-Back

$199 Full Platform · reserve now

Intercept customer.subscription.deleted with structured offramps (pause, downgrade, discount). Win-Back re-engages customers who left.

Mechanism: pre-cancel survey → conditional offer → Stripe API write. Only module that requests write scope.

Proof, not promises

Built to survive a technical founder opening DevTools.

Row-level data stays local

The CSV parses in your browser via Papa Parse. Only four aggregates are ever transmitted when you save a report: total leaked $, failed-payment count, email, and per-category totals. No customer IDs, no charge rows, no email addresses of your users.

Every number is from your own export

No industry averages passed off as your metrics. No MRR modeling, no smoothing. What's in your CSV is what we count.

Paid email sends from your domain

When the paid modules ship, dunning, trial, and cancel emails send from billing.yourdomain.com. Paritum is a footer, not the sender.

One platform at launch

When we go live, a single Stripe connection covers dunning, trial, cancel, and win-back. Not four vendors, four contracts, four dashboards.

Pricing

Free tool today. Founding-customer pricing on the rest.

A realistic Stripe-recovery stack from separate vendors at $5K MRR runs $208–328/mo: Churnkey's Starter plan is $250/mo for dunning + cancel flows (churnkey.co/pricing), Encharge Growth is $79–99/mo for trial emails (encharge.io/pricing). The Paritum Bundle is $99/mo total — one integration, one bill.
