<p><b>Startup description</b></p><p>My platform is an AI-powered oral exam simulator tailored specifically for the Polish _"Matura ustna"_—the high-stakes oral graduation exam taken by approximately 270,000 students annually. The platform allows students to simulate real exam environments by speaking with an AI examiner that pulls authentic questions, evaluates responses in real-time, and provides actionable feedback on content, fluency, and sentence structure.</p><p><b>Development &amp; Launch Timeline</b></p><p>Built entirely solo in just 4 days using Claude Code, the platform was strategically launched 6 weeks ahead of the May 2026 Matura exam period.</p><p><b>Growth &amp; Financial Highlights</b></p><ul> <li><b>Revenue:</b> Generated <b>18,278 PLN (~$4,500 USD)</b> in gross revenue within its first 6 weeks.</li> <li><b>Margins:</b> Operating at an elite <b>86% profit margin</b>.</li> <li><b>Acquisition:</b> Driven by <b>100% organic distribution via TikTok</b>, tapping into viral content centered around student exam stress during the peak prep season.</li> </ul> <p><b>Key highlights:</b></p><ul> <li>Annual revenue (peak season Apr-May 2026): $4,500 USD / 18,278 PLN</li> <li>Annual profit (after OpenAI + Vercel + domain): ~$3,900 / 15,700 PLN</li> <li>Business margin: 86%</li> <li>Average transaction: $13 / 52 PLN</li> <li>Total transactions: 335 successful (350 attempted)</li> <li>Payment methods: 70%+ BLIK (Polish instant payment), rest cards</li> <li>Refund rate: 2.1% (7 refunds out of 335)</li> <li>Customer database: 1,600+ verified emails</li> <li>Operating cost: ~$130/month during peak, ~$30/month off-season.</li> </ul> <p><b>Team</b></p><p>Solo founder. I designed, built, marketed, and operated the entire product myself.</p><p><b>Tech Stack</b></p><ul> <li>Next.js (frontend + backend)</li> <li>OpenAI API (GPT-4 for question generation and answer evaluation)</li> <li>Stripe (payments — BLIK + cards)</li> <li>Supabase (auth + database, free tier)</li> <li>Vercel (hosting, Pro plan ~$20/mo).</li> </ul> <p>The codebase is clean, well-documented, and built to be easily handed off. Buyer can plug in their own API keys and deploy in under 1 hour.</p><p><b>Marketing and growth</b></p><p>100% organic TikTok distribution. I built a content series "Pytanie jawne" (76 videos) covering all official matura exam questions — each video uses AI-generated cinematic visuals + an exam question hook.</p><p><b>Results:</b></p><ul> <li>TikTok: 17,800 followers, 160,500 likes</li> <li>Top video: 457,000 views, 34,000 likes, 18,000 shares</li> <li>2nd: 273,000 views, 24,000 likes</li> <li>Multiple videos in 100k-450k views range</li> <li>76 episodes "Pytanie jawne" — content library transfers to buyer.</li> </ul> <p><b>SEO results (Google Search Console, last 28 days):</b></p><ul> <li>19,900 organic clicks</li> <li>146,000 impressions</li> <li>#1 ranking: "symulator matury ustnej" (+401% growth)</li> <li>#1 ranking: "ustna"</li> <li>#2 ranking: "symulator ustnej z ai"</li> <li>Multiple other top-10 rankings for high-intent keywords.</li> </ul> <p><b>Revenue model</b></p><p>The model is effectively a semi-annual subscription with prepayment. Customer pays once (39-59 PLN, avg 52 PLN / $13 USD) and gets access until end of June (matura exam period). Mechanically identical to Duolingo Plus Annual, Headspace Annual, or similar prepaid annual subscriptions.</p><p>Critically, the customer base is fundamentally cohort-based with automatic renewal:</p><ul> <li>200,000-270,000 new matura takers annually (constant Polish demographic flow)</li> <li>~30,000 retakes (matura poprawkowa in August)</li> <li>TAM does NOT deplete year-over-year — it refreshes with each new graduating class</li> </ul> <p>This is the same business model used by:</p><ul> <li>Polish educational publishers (Operon, WSiP, Nowa Era) — valued at hundreds of millions PLN</li> <li>Global exam prep companies (UWorld $1.5B+, Magoosh, Manhattan Prep, Kaplan) — one-time purchases with annual cohort refresh</li> <li>Standardized test prep globally</li> </ul> <p>SEO authority, TikTok content library, and brand recognition compound year-over-year while reaching fresh audiences. Year 2 marginal cost per new customer is essentially zero since the 76-episode content library is already produced.</p><p><b>April 2 - May 17, 2026:</b></p><ul> <li>Gross volume: 18,278 PLN</li> <li>Net volume: 17,295 PLN (after refunds)</li> <li>Operating costs: ~$600 USD total (OpenAI $355 + Vercel + domain)</li> <li>Net profit: ~14,900 PLN / $3,900 USD</li> <li>Margin: 86%</li> </ul> <p>The business is highly seasonal — peak runs from February to mid-May during Polish matura preparation. Off-peak tail revenue is $15-30/day (matura poprawkowa in August, early prep by younger cohorts, organic SEO traffic).</p><p><b>Why I'm selling</b></p><p>Focusing on new ventures.
