<p>My project is a platform for managing ebook highlights and annotations across Kobo and Kindle. It helps users centralize notes, create custom annotations, add tags, and export to images or PDFs. The product was built as a one-time payment alternative to Readwise for readers who want to own their data without ongoing subscriptions.</p><p><b>Key Highlights</b></p><ul><li>Annual revenue: £400.</li><li>Net profit: £360 (minimal infrastructure costs).</li><li>Churn rate: 0% (one-time payment model).</li><li>Customer acquisition cost (CAC): £0 (entirely organic via Reddit posts).</li><li>Lifetime value (LTV): £25 per customer.</li><li>Active users in database: 120.</li></ul><p><b>Team</b></p><ul><li>Solo founder &amp; developer.</li></ul><p><b>Tech Stack</b></p><ul><li>Next.js (full-stack framework).</li><li>Firebase (database &amp; authentication).</li></ul><p><b>Marketing &amp; Growth</b></p><ul><li>Customer acquisition was entirely organic via Reddit posts.</li><li>No paid marketing has been tested yet, leaving room for scaling via ads, SEO, or partnerships.</li></ul><p><b>Revenue &amp; Profit</b></p><ul><li>Annual Revenue (ARR): £400.</li><li>Net Profit: £360.</li><li>Gross Margin: ~90%.</li><li>CAC: £0.</li><li>LTV: £25 (single purchase).</li></ul><p><b>Return on Investment</b></p><ul><li>Payback period depends on acquisition price.</li><li>At current revenue/profit levels, buyers can expect steady returns, with significant upside if subscription pricing or additional marketing channels are introduced.</li></ul><p><b>Startup Assets</b></p><ul><li>User database: 120 registered customers.</li><li>Codebase &amp; full IP rights.</li><li>Email list: 120 subscribers (via DB).</li></ul><p><b>Risks</b></p><ul><li>Reliance on a single marketing channel (Reddit).</li><li>Competitive market (e.g., Readwise and other note/highlight managers).</li><li>Limited current user base.</li></ul><p>Mitigation: Buyer can diversify acquisition channels, build a newsletter, or add integrations (Obsidian, Notion, Roam) to expand market.</p><p><b>Summary</b></p><ul><li>Profitable from day one with very low running costs.</li><li>Niche product-market fit among ebook readers looking for an affordable Readwise alternative.</li><li>Clean, simple codebase with room for easy feature expansion.</li><li>Upside potential: add subscriptions, expand marketing, or build integrations to scale beyond the current user base.</li></ul><p>This project is an ideal acquisition for an indie hacker or micro-acquirer looking for a lean, profitable SaaS with growth potential in the reading/knowledge management niche.</p></br>✅ $490 in Annual revenue✅ 81 customers✅ Business model: One-time sales✅ Built with Next.js, Vercel, Firebase
