Message from the founder
Berkay TURK

"Selling to focus on other projects. Goldn launched June 2026 and already has ~45 active paying subscribers (~€250 MRR) with no dedicated marketing budget beyond TikTok. Native Swift/SwiftUI codebase, RevenueCat + AppsFlyer/SKAdNetwork already integrated, localized in 5 languages, widgets included. Full source code, App Store listing, RevenueCat project and assets transfer with the sale. Great fit for anyone who can scale paid UA (TikTok/Meta/ASA) in the summer season."
