<p><b>Startup description</b></p><p>My product is an AI tool for Roblox creators. They describe what they want in a web chat, and a Roblox Studio plugin applies the result to their open place: working Luau scripts, complete game systems (tycoon, combat, obby and more) and generated 3D models. Common builds run from tested server-side recipes instead of free-form generation, so they come out working more often. It went live in May 2026 and has been paid-only since July 2026.</p><p><b>Key highlights:</b></p><ul> <li>Revenue: $1,665 gross from July 1 to September 24, 2026 (Dodo Payments). About $4.5k current ARR.</li> <li>Profit: about $250-300 net per month since July, after payment fees and running costs.</li> <li>Churn: high. About 60% of MRR churned in the last 30 days, so retention is the first thing to fix.</li> <li>CAC: $0. Every customer came organically.</li> <li>Margin: AI model cost is the main expense and is logged per user per day.</li> <li>17 active subscriptions, with customers in the US, France, the UK, Qatar, Chile and across Europe.</li> </ul> <p><b>Team</b></p><p>Just me. I built and run everything: backend, Studio plugin, AI pipeline, site and content. Scheduled jobs handle billing reconciliation, monthly credit refills and lifecycle emails.</p><p><b>Tech Stack</b></p><p>Next.js, React, TypeScript and Tailwind on Vercel. Supabase (Postgres) and Upstash Redis. Anthropic Claude for code generation, OpenAI embeddings, Replicate for image and 3D generation. A Luau plugin published on the Roblox Creator Store. About 108k lines of code with a test suite.</p><p><b>Marketing and growth</b></p><p>All organic: a library of how-to guides, blog posts and comparison pages, posts on X, Reddit and the Roblox DevForum, and the Creator Store listing. No paid ads so far. Promotion has been paused since mid-September.</p><p><b>Revenue and profit</b></p><ul> <li>Monthly gross (Dodo): July $607, August $541, September 1-24 $517.&nbsp;</li> <li>Net after Dodo fees: $494, $475, $441.&nbsp;</li> <li>Running costs are about $200 a month.&nbsp;</li> <li>MRR today is $376.&nbsp;</li> <li>Plans: monthly and yearly subscriptions plus one-time credit packs, sold through a merchant-of-record processor that handles sales tax.</li> </ul> <p><b>Return on investment</b></p><p>Payback depends on the price. The fastest levers are retention (most subscribers build in their first days, then stop) and distribution, where no money has been spent yet.</p><p><b>Startup assets</b></p><p>Everything below is included in the sale:</p><ul> <li>Domain and the website with its content (how-to guides, blog, comparison pages)</li> <li>Full codebase: web app, backend, Roblox Studio plugin and an unreleased desktop app</li> <li>The Roblox Studio plugin on the Creator Store and its publishing group</li> <li>Customer base and active subscriptions</li> <li>Social accounts: X, YouTube, TikTok</li> <li>Brand</li> </ul> <p><b>Risks</b></p><p>Dependency on Roblox and Roblox Studio; Roblox also ships its own AI assistant. AI model costs can spike with heavy users, so credit pricing and model routing need watching. Churn is high, so retention work comes first.</p><p><b>Summary</b></p><p>A working, paid-only AI product in a large creator market, with paying customers on four continents, zero ad spend, and clear next steps for someone who can give it full-time focus. Handover support is included.</p><p>✅ $1,665 TTM revenue</p><p>✅ 17 customers</p><p>✅ Business model: SaaS</p><p>✅ Built with Next.js, React, Supabase</p>
