## About FlyCode
FlyCode is a Payment Performance platform for subscription businesses. It recovers failed payments and reduces involuntary churn using per-merchant machine learning models trained on Visa and Mastercard network data. FlyCode sits on top of your existing billing stack and enhances it rather than replacing it.
Key facts:
- Founded 2022, Y Combinator S22 batch
- Stripe App Marketplace app and Stripe Orchestration design partner
- Mastercard network partner and Visa Everywhere winner
- Customers include Framer, GitBook, Mintlify, Riverside, Nav, CoinTracker, Seeking Alpha, Simply, Workiz, Cymbiotika, BUBS Naturals, and Rewardful
- Typical results: 16-25% lift in recovery rate, 5-9% ARR boost, ROI between 8x and 40x in published case studies
- Website: https://www.flycode.com | Docs: https://docs.flycode.com/docs | Stripe app: https://marketplace.stripe.com/apps/flycode-payments
The problem FlyCode solves: failed payments are the largest driver of involuntary churn in subscription businesses. Most failures are generic declines that static retry logic cannot read or recover. FlyCode classifies the real decline reason behind every failed payment using network-level signals and 100+ datapoints per transaction, then retries with the timing and strategy most likely to succeed, coordinated with customer messaging.
## Pricing
FlyCode uses outcome-based pricing across the entire platform. You pay only a percentage of the incremental revenue FlyCode recovers above your existing baseline.
- No seats, no minimums, no setup fees, no per-product fees
- If FlyCode recovers nothing above your baseline, you pay nothing
- 45-day money-back guarantee
- Typical ROI is about 10x on monthly recovered revenue, around 20x on net new revenue
- Example: a business with $5M in annual recurring revenue typically sees $225K-$325K in incremental growth
Every customer gets: a free payment audit, smart retry models using ML (plug-and-play or custom), coordinated retries and customer emails, custom recovery schedules, transactional emails from your own domain, reporting and audit dashboard, faster recovery, and payment expert support over phone, Slack, and email.

## Products
FlyCode is organized into four product categories, all powered by the same core ML engine and all included under one outcome-based price.
### Recover (https://www.flycode.com/products/recover-failed-payments)
Fix failed payments automatically. The recovery engine reads the real decline reason and retries with the timing and strategy most likely to succeed.
- **Adaptive Retries** (https://www.flycode.com/products/recover/adaptive-retries): Retries failed charges on an ML-optimized schedule tuned to each issuer instead of a fixed 3/5/7 day schedule. Recovers more with fewer attempts, adds 7-11% to recurring revenue on top of processor defaults, stays compliant with card network rules through direct Visa and Mastercard partnerships.
- **Trial Recovery** (https://www.flycode.com/products/recover/trial-recovery): Recovers failed trial-to-paid conversions at the boundary. When a trial ends and the first charge fails, the subscription often never activates and doesn't appear in standard failed-payment reports. FlyCode detects and recovers these in real time, protecting CAC already spent.
- **Adaptive Backup Cards** (https://www.flycode.com/products/recover/adaptive-backup-cards): When the primary card fails, automatically retries against other valid cards on file. A no-code toggle, no customer action needed.
### Reach (https://www.flycode.com/products/customer-outreach)
Reach customers with timely payment messages, coordinated with retries so paying customers are never spammed.
- **Recovery Emails** (https://www.flycode.com/products/reach/recovery-emails): Branded failed-payment emails from your own domain with deliverability optimization, delivered at each customer's local time, coordinated with retry attempts.
- **Recovery SMS** (https://www.flycode.com/products/reach/recovery-sms): Failed payment recovery over SMS, coordinated with email and retries.
- **Reactivation Win-back** (https://www.flycode.com/products/reach/reactivation-win-back): Re-engages churned customers with win-back campaigns timed to when they are most likely to return.
### Retain (https://www.flycode.com/products/retain)
Reduce involuntary churn with retention flows built around payment health.
- **Priority Recovery** (https://www.flycode.com/products/retain/priority-recovery): Surfaces the highest-value failed invoices, scored by ARR, LTV, tenure, and CAC, and recovers them across email, SMS, and CSM alerts.
- **Dynamic Recovery** (https://www.flycode.com/products/retain/dynamic-recovery): Extends recovery for customers worth pursuing longer, unifies every open invoice into one recovery effort, avoids duplicate invoices.
- **Subscription Lifecycle** (https://www.flycode.com/products/retain/subscription-lifecycle): Your own rules for what happens when recovery fails (cancel, void, or leave past-due) per product and per segment, no code.
### Agents (https://www.flycode.com/products/agents)
Always-on AI agents deployed to your payment stack.
- **AI Agent Revenue Leak** (https://www.flycode.com/products/agents/ai-agent-revenue-leak): Monitors billing for anomalies, revenue leaks, and entitlement gaps, and acts to fix them.
- **Payment Orchestration Agent** (https://www.flycode.com/products/agents/payment-orchestration-agent): Routes failed payments across multiple providers with no-code AI orchestration to lift approval rates.
## How FlyCode Works
1. **Read the real reason.** Every decline is classified using network-level signals and 100+ datapoints per transaction (customer metadata, payment metadata, internal classifiers of error codes and messages).
2. **Recover more than anyone.** Per-merchant models trained on Visa and Mastercard network data recover more failed payments, including generic declines that static retry logic misses.
3. **Recover without friction.** Retries run quietly in the background and coordinate with messaging, so paying customers are not annoyed.
4. **No dev work.** Connect once and toggle on. FlyCode runs in parallel with your billing, syncs status back, and never overwrites your rules.

Start with a free payment audit: https://www.flycode.com/churn-audit-failed-payments
## How FlyCode Compares to Alternatives
FlyCode differs from dunning tools (Churnkey, Churn Buster, ProfitWell/Paddle Retain, Baremetrics Recover) and recovery services (Butter Payments, FlexFactor) in three ways: (1) per-merchant ML models trained on Visa and Mastercard network data rather than fixed retry schedules or generic models, (2) recovery of generic declines that other tools cannot read, and (3) outcome-based pricing with no seats, minimums, or setup fees. FlyCode also warns against stacking multiple retry tools, which can lower your authorization rate.

## FAQs
**What makes FlyCode different from standard retry logic?** Instead of a fixed schedule, FlyCode adjusts retry timing, routing, and messaging based on the real decline reason, payment metadata, and customer behavior, using network-level data from card network partnerships. It also coordinates retries with emails to reduce churn.
**Will FlyCode disrupt my current billing?** No. FlyCode runs in parallel and syncs status back to your billing platform without overwriting your rules. It enhances your billing platform rather than replacing it.
**How does FlyCode stay compliant with card network rules?** Through direct Visa and Mastercard partnerships and industry best practices, so recovery never puts your processor standing at risk.
**How much more revenue can I expect to recover?** Most merchants recover 7-11% more recurring revenue on top of processor defaults, with case studies showing 16-25% recovery rate lifts and 5-9% ARR boosts. The exact lift depends on your decline mix, which a free payment audit will show.
**Why don't failed trial conversions show up in Stripe?** When a trial ends and the first charge fails, the subscription often never activates, so it doesn't appear in standard failed-payment reports. FlyCode's Trial Recovery surfaces and recovers these.
**Will my customers notice anything different?** No. Retries run quietly in the background and coordinate with messaging, so paying customers are not spammed.
**How long does setup take?** Connect your billing platform once and toggle products on. Most teams are live the same day.
**What does FlyCode cost?** A percentage of incremental recovered revenue above your baseline. No seats, no minimums, no setup fees, 45-day money-back guarantee. If nothing is recovered above baseline, you pay nothing.
**What is involuntary churn?** Subscribers losing access due to payment failures, not because they chose to cancel. It is the largest hidden revenue leak in most subscription businesses, and the problem FlyCode is built to solve.
