Founder, Cramly
Cramly is an AI-powered writing assistant built for students. It helps users generate long-form essays with citations, solve multiple-choice questions, and create personalized study materials.
With over 1 million users worldwide, Cramly has become a go-to tool for students seeking to enhance their academic performance.
Despite its rapid growth, Cramly faced significant revenue leakage due to failed payments.
Relying on Stripe's Smart Retries, the platform achieved a recovery rate of only 18.4%, meaning less than 2/10 subscribers were being saved. This was a substantial amount of revenue uncollected.
This issue was particularly pronounced given Cramly's predominantly student user base, which often exhibits unique payment behaviors and sensitivities.
Cramly partnered with Redux to go beyond generic retry logic and build a smarter, more targeted recovery engine tailored to their audience.
Redux mapped payment timing against student behavior patterns, including payday cycles and weekend activity. This allowed the system to optimize retry windows and catch recoverable payments when funds were most likely to be available.
Rather than retrying blindly, Redux adjusted its logic based on geography, card network, and bank issuer. These micro-optimizations helped Cramly improve recovery in regions where Stripe’s default approach often failed.
Redux’s AI engine continuously learned from every failed attempt. By tracking what worked, for which users, and under what conditions, the system evolved over time. This created a compounding cycle of improvement that boosted results automatically.
With payment recovery transformed from a persistent challenge into a strategic advantage, Cramly is now better positioned to reinvest in product development and expand its market reach.
The partnership with Redux not only stabilized revenue streams but also enhanced the overall user experience, reinforcing Cramly's commitment to supporting students in their academic pursuits.
