<p>My product is a developer tool for solo founders and indie hackers who build with AI coding assistants. Users run one command and a team of specialist agents takes their idea from brainstorm to architecture, test-first build, code review and deployment, pausing for approval at each step. A local memory feature lowers token usage. Launched in August 2026 and built by a solo founder.</p><p><b>Key highlights:</b></p><ul> <li>105+ active subscriptions in about 7 weeks since launch</li> <li>MRR: $343</li> <li>Churn: 2 subscriptions lost in the last 30 days (about 1.8%)</li> <li>Checkout conversion: 13.8%</li> <li>Margin: about 99% (costs around $15/month)</li> <li>LTV and CAC: not tracked yet, growth has been organic with no paid acquisition</li> </ul> <p><b>Team</b></p><p>Solo founder: product, backend, infrastructure and distribution. Time needed to run it: about 30 minutes a day, mostly for social posts. Onboarding is automatic, with one manual API call for enterprise clients.</p><p><b>Tech Stack</b></p><p>NestJS (backend), PostgreSQL (database), React (frontend), hosted on Railway. Payments through Polar.</p><p><b>Marketing and growth</b></p><p>All organic: posts on X, a blog and the Agents. surf directory, Google search, and citations in ChatGPT and other AI assistants. No paid ads. The product reached 105+ subscribers within weeks of launch.</p><p><b>Revenue and profit</b></p><p>Revenue verified through Polar. MRR $343. Monthly costs about $15 (Railway hosting and analytics) plus payment fees. One enterprise client pays $420 per year. There is no history before August 2026.</p><p><b>Return on investment</b></p><p>At the current MRR the payback is long, so the ask is based on momentum and upside, not on today's revenue. A new pricing model is planned and the active base gives room to grow revenue without extra costs. The buyer inherits a product that already converts at 13.8%.</p><p><b>Startup assets</b></p><ul> <li>Full source code and the domain</li> <li>105+ active subscribers and one enterprise client</li> <li>Email list, social profiles and all accounts</li> <li>Brand assets and product screenshots</li> <li>Founder support for the full migration, and available afterwards.</li> </ul> <p><b>Risks</b></p><ul> <li>Very young product: 7 weeks of history, so retention is not proven over time. Mitigation: access to the full Polar data before closing.</li> <li>Depends on the AI coding tools ecosystem (Claude Code, Cursor, Codex). Mitigation: the kit works across several tools.</li> <li>Growth relies on the founder posting on X. Mitigation: handover of the content approach and of the accounts.</li> <li>One enterprise client at $420 per year. Revenue does not depend on it.</li> </ul> <p><b>Summary</b></p><p>My tool is a profitable, automated developer product that grew to 105+ subscribers in about 7 weeks with no ads, at ~99% margin and about 30 minutes of work per day. A buyer gets working code, an active customer base, one enterprise client and a founder who supports the migration, with clear upside from the planned pricing update.</p><p>✅ $3,975 TTM revenue</p><p>✅ 111 customers</p><p>✅ Business model: SaaS</p><p>✅ Built with Next.js, React, PostgreSQL</p>
