<p><b>Startup description</b></p><p>My startup is a mobile app that allows users to create personalized stories and chat with their own custom characters in real time. Combining storytelling with AI character interaction. The app appeals to writers, readers, roleplayers, and creative users looking for interactive entertainment.</p><p>It launched in April 2025 and is available on iOS and Android.</p><p><b>Key highlights:<b></b></b></p><ul><li>$1,442 in revenue in 7 months of existence</li><li>23 active subscribers (out of 60 total new customers lifetime, including 7 yearly subs)</li><li>$0 CAC (Fully organic)</li><li>7,700+ downloads Android (Mostly US)</li><li>3,240+ downloads iOS (Mostly US)</li><li>1M+ organic TikTok views (content still generating views &amp; downloads)</li></ul><p><b>Team</b></p><p>Solo founder / operator.</p><p><b>Tech Stack</b></p><ul><li>Frontend: React Native + Expo (cross-platform iOS &amp; Android).&nbsp;</li><li>Backend: AWSAI Engine: Gemini (Story generation &amp; character chat)</li></ul><ul><li>Payment Processing: RevenueCat&nbsp;</li><li>Website: Cloudflare&nbsp;</li><li>Database: Firebase</li></ul><p><b>Marketing and growth</b></p><p>The main marketing channel was TikTok. With consistent posting using my own SOP, I've managed to generate over 1M+ organic TikTok views, converting directly to thousands of downloads and hundreds in monthly revenue.</p><p>I've also done some work in optimizing the App store &amp; Play store listing, resulting in a steady inflow of new customers. Current listing continues to drive steady downloads without ads.</p><p><b>Revenue and profit</b></p><ul><li>Lifetime total subscription revenue (April–October): $1,042</li><li>Lifetime total ad revenue (April–October): $400</li></ul><p>As of October 21st, 2025:</p><ul><li>23 active subscribers (7 yearly)</li><li>$145 MRR</li><li>$164 subscription revenue in the last 28 days</li></ul><p><b>Return on investment</b></p><p>Over the past 7 months:</p><ul><li>Average ad income: $57/month</li><li>Average subscription revenue: $149/month</li></ul><p>Without any additional input, the return on investment would be around 17 months. However, following the included TikTok SOP can shorten that to less than 3 months. One viral TikTok has already added several hundred dollars and retained multiple subscribers.</p><p>This project has low competition, a unique concept, and is highly scalable.</p><p>Large TAM, (booktok (teenagers), kids stories, also features similar to character AI, sage stories (low competition).</p><p><b>Startup assets<b></b></b></p><ul><li>iOS App (full app + source code)</li><li>Android app (full app + source code)</li><li>TikTok account with 2,200 followers, 127k likes, 1M+ views, ready to post</li><li>Website + domain. (Cloudflare-hosted and easy to migrate)</li></ul><p><b>Risks</b></p><p>The main risk is that growth depends on consistent content posting. The included SOP and warmed-up TikTok account make this easy to manage.</p><p>I have other business ventures that need my full attention, so I’m selling this one to free up time and focus on those projects.</p><p><b>Summary</b></p><p>My startup sits in a large market with lots of potential BookTok readers, creative writers, teenagers, and fans of Character AI–style apps. It’s a unique product with low competition, strong early traction, and plenty of room to scale.</p></br>✅ $1,442 in ARR✅ 23 customers✅ Business model: SaaS+Ads✅ Built with Expo, AWS, React Native
