FlyCode helps subscription merchants maximize revenue. We reduce involuntary churn by managing payment failures intelligently. We’re Jake, Etai, and Tzachi and we’re building FlyCode. TL;DR: If you sell SaaS or B2C subscriptions, we’re here to help you recover lost revenue due to failed payments and involuntary churn. ‘Involuntary’ or ‘Passive’ churn is a hidden Revenue Killer 💳 for Subscription Businesses ❌ THE PROBLEM: Recovering Failed Payments is Complex Involuntary churn refers to the loss of subscribers due to payment failures, not due to them actively canceling. While it is both possible and a worthwhile strategy to attempt to win back a customer during the cancellation process — involuntary churn is not intentional and in most cases, your customers aren’t even aware that their payment failed. 💰 Bottom line? Effective payment optimization does reduce involuntary churn and will increase ARR by as much as 5-10% FLYCODE SOLUTION 💡 FlyCode leverages ML and AI to provide Payment Optimization and smart payment retries to maximize subscription revenue and reduce churn. We apply a unique model tailored to each Merchant and their customers to ensure optimal results. ⚡️Automatically recover failed subscription payments and reduce passive churn ⚡️Use ML & AI based payment optimization to find the best time to charge your customers ⚡️ Improve customer experience by coordinating payment retries with customer emails/SMS 🛠️ We support OOTB + Custom Integrations for Merchants and White-Label for Platforms

💡 What is Pandai? Pandai is an app that helps students get better grades in school. Pandai provides gamified quizzes aligned to a specific school curriculum, from which students can learn, practice, get feedback, and diagnose their weaknesses. 🔥 Why do we build this? In Southeast Asia, the education system is competitive and exam-oriented. There is a huge demand for interventions (tutors, workbooks, and extra classes) to help students perform better in school. Pandai fills the demand with a solution that is better than the alternatives. 👨‍🏫 Who We Are The three founders are based in Malaysia and have known each other since high school, 23 years ago. After we graduated (from MIT & other US colleges), we started our first education company in 2007, focusing on coaching school students in STEM subjects. We worked closely with students (many of them from underprivileged backgrounds) and saw firsthand the impact we’ve had on them. We then realized that with technology, we could reach more students and bring more impact. Hence, we released Pandai in 2020. 🚀 Present & Future Currently, we have launched in our home ground Malaysia in 2020. So far, 280,000 students have completed 83 million questions on Pandai, and 92% of users have seen some improvement in their academic performance. We plan to expand to Southeast Asia and other emerging markets, a market of 100M+ school students. Pandai is designed to be scalable, and our content (also available in English) can be mapped to other curricula from other countries.
