<p><b>Startup description</b></p><p>My product is a professional iOS projection mapping app that transforms any iPhone or iPad into a powerful real-time visual projection tool. Users create multi-layer projection mapping projects with custom shapes, map them onto physical surfaces using corner-pin warping, and fill them with a vast library of 40+ GPU-accelerated Metal shader visualizers, static/video content, and real-time generators — all driven by a blazing-fast Metal rendering pipeline.</p><p>The app connects to external displays (projectors, TVs) via HDMI/USB-C or AirPlay and outputs full-resolution visuals in real-time, turning any surface into an immersive light show.&nbsp;</p><p><b>Key highlights:<b></b></b></p><ul> <li>Annual revenue : $400</li> <li>Annual profit : $400</li> </ul> <p><b>Team</b></p><p>This is a one-person operation, which means extremely low overhead, no team coordination friction, and all institutional knowledge transfers directly with the sale. The buyer inherits a well-structured, maintainable codebase built with modern frameworks and clean architecture patterns.</p><p><b>Tech Stack</b></p><p><b>iOS App (Core Product)</b></p><ul> <li>Swift / SwiftUI: Native iOS UI framework — all views, navigation, and state management.</li> </ul> <ul> <li>Metal (Apple GPU API): Custom real-time rendering engine — 40+ shader kernels, anti-aliasing, fragment effects, video effects, kaleidoscope, generator system.</li> </ul> <ul> <li>Metal Shading Language: 120KB+ of custom GPU shader code — visualizers, effects, post-processing.</li> </ul> <ul> <li>RevenueCat: Subscription management, paywall presentation, entitlement verification.</li> </ul> <ul> <li>Firebase (Anonymous Auth): User identity for analytics and purchase syncing without requiring sign-up.</li> </ul> <p><b>Backend / Admin Panel</b></p><ul> <li>Next.js 16 (App Router): Full-stack web framework — admin dashboard + REST API.</li> </ul> <ul> <li>Vercel: Hosting, serverless functions, edge caching.</li> </ul> <ul> <li>Vercel Postgres (Neon): PostgreSQL database — users, store items, categories, downloads, purchases.</li> </ul> <ul> <li>Drizzle ORM: Type-safe database queries and migrations.</li> </ul> <ul> <li>NextAuth.js: Admin panel authentication.</li> </ul> <ul> <li>Vercel Blob: Storage Media file storage for storing item previews.</li> </ul> <p><b>Marketing and growth</b></p><ul> <li>App Store Optimization: Keyword-optimized listing, screenshots</li> </ul> <ul> <li>Reddit Posts in r/projectionmapping, r/vjing, r/lightshows, r/iosdev communities.</li> </ul> <ul> <li>Instagram &amp; Tiktok : Feature showcase reels and before/after projection videos.</li> </ul> <ul> <li>Youtube Shorts.</li> </ul> <ul> <li>Landing page.</li> </ul> <p><b>Revenue and profit</b></p><ul> <li>MRR : $108 - 22 active subscriptions, last 28 days, (19.04.2026 last update)</li> </ul> <ul> <li>Last 30 Days Revenue : 194$ (19.04.2026 last update)</li> </ul> <ul> <li>Lifetime Revenue : 400$ (19.04.2026 last update).</li> </ul> <p><b>Startup assets<b></b></b></p><ul> <li>XCode Project Files</li> <li>Landing Page Project Files</li> <li>Instagram + Tiktok + Reddit Accounts</li> <li>All Store Content</li> <li>Firebase + Revenuecat Transfers</li> </ul> <p><b>Risks</b></p><ul> <li>Apple platform lock-in: Revenue depends on the iOS App Store.</li> </ul> <ul> <li>Metal shader complexity: GPU programming requires specialized knowledge.</li> </ul> <ul> <li>Niche market: Projection mapping is a niche market, but has some virality effect currently.</li> </ul> <ul> <li>Churn: Users may cancel subscriptions.</li> </ul> <p><b>How Buyers Can Accelerate ROI</b></p><ul> <li>Expand the visualizer library — Each new Metal shader is a reason for users to return and subscribe. The architecture makes adding new visualizers trivial (add a Metal kernel + one registry entry).</li> <li>Android port — The market for projection mapping on Android is completely empty. Porting the core concept (not the Metal code) to Android using Vulkan/OpenGL could 2-3x the addressable market.</li> <li>Increase pricing — No direct competitor exists on iOS at this quality level. Premium pricing is justified.</li> <li>Add one-time purchase items — The store system already supports is_premium items (one-time unlocks) alongside subscriptions. This is built but underutilized.</li> <li>B2B licensing — License the engine to event companies, AV rental shops, or educational institutions.</li> <li>Content marketplace — Allow creators to submit and sell custom visualizers/content packs (the store + admin panel infrastructure is already in place).</li> </ul> <p><b>Summary</b></p><ul> <li>No Real Competition on iOS</li> </ul> <p>There is no comparable projection mapping app on iOS. Professional tools (MadMapper, Resolume) are desktop-only and cost $200-$700+. My app owns this niche on mobile.</p><ul> <li>Deep Technical Moat</li> </ul> <p>The 40+ custom Metal shaders represent months of specialized GPU programming that cannot be easily replicated. The real-time rendering engine, audio-reactive FFT pipeline, and MIDI integration create significant barriers to entry for any competitor.</p><ul> <li>Built for Scale.</li> </ul> <p>The architecture is production-ready and extensible:</p><ul> <li>Adding a new visualizer = 1 Metal kernel file + 1 registry entry</li> <li>The admin panel enables non-technical content management</li> <li>The store system supports both subscriptions and one-time purchases</li> <li>The backend is serverless (Vercel) — scales automatically with zero ops</li> </ul> <ul> <li>Growing Market</li> </ul> <p>Affordable projectors are becoming mainstream ($200-500 range). Every new projector owner is a potential user of ours. The market for mobile creative tools is expanding rapidly.</p><ul> <li>Clean, Recurring Revenue</li> </ul> <p>100% subscription-based, no ads, no physical goods. RevenueCat handles all payment infrastructure. Revenue is predictable and grows with the user base.</p><ul> <li>Massive Untapped Growth</li> </ul> <p>Marketing has been minimal, organic growth only. A buyer with marketing expertise could scale downloads significantly through YouTube tutorials, TikTok content, VJ community partnerships, and App Store Ads.</p><ul> <li>Low Operating Costs</li> </ul> <ul> <li>Vercel hosting: Free/Hobby tier covers current scale</li> <li>Database: Vercel Postgres (included)</li> <li>RevenueCat: Free tier until significant revenue</li> <li>Firebase: Free tier for anonymous auth</li> <li>Total monthly operating cost: ~$0-20/month</li> </ul> <ul> <li>Solo Founder = Clean Acquisition</li> </ul> <p>No team to retain, no complex equity structures, no HR overhead.
