Partnership Proposal
Turning Cancellations Into Revenue
RevenueCat × MomentScience

CancelAds™ — Incremental revenue at the exact moment users cancel or end their free trial. Purpose-built for mobile subscription apps.
TL;DR
The Opportunity in 30 Seconds
CancelAds™ monetizes the most overlooked moment in mobile subscriptions — the cancellation screen. Here's how it works:
Free Trial Ending
Show an offer (or a perkswall with multiple offers) at the moment of trial cancellation. Complete an offer → earn a trial extension. Example: "Sign up for Hulu for 30 days and get 2 more months free."
Paid Subscription Cancel
When a paying user initiates cancellation, present relevant offers to stay on board for X more months. Same dynamic — complete an offer, keep the subscription.
Already Cancelled?
"We're sorry to see you go! Check out our other partners." Surface curated third-party offers post-cancellation and generate incremental revenue from churned users.
CancelAds™ in action — a live offer shown at the cancellation moment.
Why MomentScience
We Bring Everything to the Table
The Offers
A live network of premium brand partners — Hulu, Max, Apple, Walmart, SiriusXM, and more — ready to monetize your cancellation moments out of the box.
The Tech
Simple, production-ready APIs and SDKs that integrate seamlessly with your existing systems. iOS, Android, Flutter, React Native — minimal lift, maximum impact.
The Proof
Already live with top partners including AT&T, OfferUp, and TextNow — delivering 50M+ impressions per month across the network.
The Problem
Churn Is Costly. Most Apps Leave Money on the Table.
Acquisition Spend Goes to Waste
RevenueCat customers invest heavily in UA and paywall optimization — but the cancellation moment is entirely ignored.
Zero Revenue at Exit
When a user cancels a trial or paid subscription, they're gone — with no revenue recovered and no final engagement attempt.
No Native Solution
RevenueCat has no built-in tool to monetize or retain users at this critical last-touchpoint moment.
5–7%
Monthly Subscriber Churn
The average mobile app loses this share of its subscriber base every single month.
The cancellation screen is the last touchpoint — and it's completely untapped.
The Solution
CancelAds™: Strategically Timed Ads at the Cancellation Moment
1
Free Trial Ending
A user about to cancel their trial sees a compelling offer. Completing it earns them a trial extension — and the publisher earns ad revenue. A win for both sides.
2
Paid Subscription Cancellation
A user initiating cancellation of a paid plan is shown a relevant offer. Completing it extends their subscription — recovering revenue that would otherwise be permanently lost.
3
Post-Cancellation Monetization
After cancellation completes, curated third-party offers are surfaced — generating incremental revenue from churned users who have already left.

Powered by OfferOS™ — MomentScience's offer operating system — with production-ready SDKs and APIs for seamless mobile integration across iOS, Android, Flutter, and React Native.
