Problem

Mobile app developers lose a substantial share of subscription and in-app-purchase revenue to Apple and Google platform fees, while moving customers to direct billing can damage conversion because users are accustomed to native store checkout. ZeroSettle’s clearest use case is helping an app switch existing, established subscribers to web checkout—using targeted offers and discounts—so the developer retains more revenue without forcing every customer through an unfamiliar payment flow.

The economics are significant: ZeroSettle describes the alternative as replacing a roughly 30% app-store commission with either a 5% + 50¢ managed Merchant-of-Record fee or a 0.5% platform fee when the developer uses its own Stripe account. The pain extends beyond payment processing to tax, chargebacks, billing support, and entitlement management, all of which make building direct billing internally costly and operationally difficult.

Product / Service

ZeroSettle is a drop-in web-checkout and subscription-lifecycle SDK for iOS and Android. It processes payments through Stripe rather than StoreKit or Google Play Billing, maintains cross-platform entitlements and transaction records, and supports Swift, Kotlin, and Flutter, with React Native listed as coming soon. Developers can use ZeroSettle’s managed mode, in which it becomes the Merchant of Record and handles tax remittance, chargebacks, and billing support, or bring their own Stripe account and retain those responsibilities.

The product combines direct billing with revenue-growth tooling: analytics, pricing experiments, campaigns, regional pricing, and an Autopilot engine that continuously prices markets and optimizes revenue. The benefit is a single integration that can increase take-home revenue, provide faster payouts and more control over customer relationships, and avoid charging ZeroSettle fees on purchases that still run through the App Store or Google Play.

Market

ZeroSettle competes in mobile-app monetization and payment infrastructure, specifically the emerging direct-billing layer between app developers and the major mobile app stores. Adjacent competitors and alternatives include subscription-management platforms such as RevenueCat, Adapty, Qonversion, and Superwall; payment infrastructure providers such as Stripe Billing and Paddle; and native Apple and Google billing. Its differentiation is combining the migration from native billing with checkout, Merchant-of-Record services, entitlements, analytics, and pricing optimization.

The company appears to be early-stage rather than a publicly demonstrated scaled business. Y Combinator describes ZeroSettle as a 15-minute drop-in SDK built by former Apple engineers and says the opportunity was opened by changes following the Epic v. Apple litigation, while PitchBook reports $500,000 raised from Y Combinator and Palm Drive Capital. The available evidence does not disclose customer counts, revenue, or a verified production-scale deployment, so traction beyond its YC-backed launch and financing cannot be quantified from the research.
