<p><b>Startup description</b></p><p>My platform connects to a company's telephony (Binotel, UniTalk, Ringostat, or manual/API upload), transcribes 100% of recorded calls, scores each conversation against the customer's own criteria checklists, and then performs the follow-up work itself: creates and updates leads in the CRM, fills in customer cards, writes rows to Google Sheets, and sends complaint and quality alerts to Telegram and Slack. It replaces manual QA (where typically only 5-30% of calls ever get checked) with automated 100% coverage, plus per-agent mistake analysis pinned to specific lines of the transcript.</p><p>The project was launched in September 2025 as a solution to a real pain in high-call-volume niches (hotels/HoReCa, online schools, e-commerce): call quality directly affects revenue, but nobody has time to listen to calls. Setup takes 30-60 minutes, and the product works pay-as-you-go with a small free starting balance, no card required.</p><p><b>Key highlights</b> (last 30 days, from the live analytics dashboard):</p><ul> <li>Revenue: $160/mo, about $1,925 annual run-rate</li> <li>Gross profit: $138/mo at an 85.9% gross margin, about 6x markup over AI provider costs</li> <li>COGS (STT + LLM APIs): only $23/mo</li> <li>Usage: 23,488 processed requests/mo (about 780/day), 89+ hours of audio analyzed per month, 42M+ LLM tokens per month</li> <li>2 paying B2B customers (ASAM: 12.7k requests/mo, Foodcartel: 10.7k requests/mo), both active and paying since onboarding</li> <li>Churn rate: 0% since launch, no customer has ever left</li> <li>CAC: $0, both customers acquired organically with zero marketing spend</li> <li>Business model: pay-as-you-go with per-service markup, so revenue scales linearly with customer call volume, no per-seat friction.</li> </ul> <p><b>Team</b></p><p>Solo founder who is both the developer and product owner: architecture, full-stack development, DevOps, integrations, customer onboarding, and support are all handled by one person. This means low operational complexity for a buyer: there is a single point of knowledge transfer, complete familiarity with every part of the system, and no team dependencies or payroll to take over.</p><p><b>Tech Stack</b></p><p>A modern, well-documented monorepo, built for cheap operation and easy scaling:</p><ul> <li>Backend: Python / FastAPI, PostgreSQL (+ pgvector for embeddings), Redis, Celery with dedicated queues (processing / webhooks / system) for async call pipelines, Alembic migrations, OpenTelemetry instrumentation</li> <li>Frontend: Next.js + React app, separate admin panel, shared shadcn/Radix UI component package, pnpm workspace, Playwright e2e tests</li> <li>Marketing site: separate Next.js repo, 4 locales (UK/EN/PL/DE), SEO-ready (sitemap, llms.txt), content managed via Directus CMS</li> <li>AI layer (multi-provider, swappable adapters): AssemblyAI, Soniox, ElevenLabs, and Google for speech-to-text; OpenAI, Google Gemini, and OpenRouter for analysis. Provider-per-service selection lets you optimize cost and quality per language.</li> <li>Integrations: Binotel, UniTalk, Ringostat telephony; KeyCRM, NetHunt CRM; Google Sheets, Slack, and Telegram bot actions; trigger/automation engine for custom rules</li> <li>Infra: Docker, deployed via Dokploy; full admin panel with billing, tariffs, markups, currency management, and usage analytics</li> </ul> <p><b>Marketing and growth</b></p><p>The product has never been marketed. Both paying customers came through the founder's personal network, with $0 spent on advertising, which means the entire growth playbook is untouched:</p><ul> <li>A multilingual SEO marketing site with industry-specific landing pages (HoReCa, EdTech, e-commerce), a blog, and a help center is already built and live</li> <li>The activation funnel is frictionless: pay-as-you-go with a free starting balance and no card required, so prospects test on their own real calls</li> <li>Untapped channels: outbound to the target verticals, partnerships with telephony providers (Binotel/Ringostat ecosystems), content/SEO, and the Polish and EU markets the site is already localized for.</li> </ul> <p><b>Revenue and profit</b></p><ul> <li>MRR: about $160, annual run-rate about $1,925</li> <li>Gross margin: 85.9%; monthly gross profit about $138</li> <li>Revenue since launch: generating income continuously since September 2025 (11 months)</li> <li>Churn: 0%. Both customers have paid continuously since onboarding, and their usage grows with their call volume, so expansion revenue is built into the model</li> <li>LTV: not yet capped, since no customer has ever churned in 11 months of operation</li> <li>CAC: $0 to date (organic acquisition only)</li> <li>Usage-based pricing: the platform charges a configurable markup (currently about 6x on average) on top of raw AI costs per service (STT, analysis, embeddings, speaker roles), so margins are structural, not promotional</li> <li>Cost structure is fully variable ($23/mo in AI API costs) plus a single low-cost VPS stack.</li> </ul> <p><b>Return on investment</b></p><p>Asking price: $10,000.</p><p>This is an early-stage product priced for its assets and proven economics, not as a cash-flow multiple. What a buyer gets is a competitive, fully finished platform in a hot vertical (AI call QA and post-call automation) with unit economics already validated on real paying customers: an 85.9% gross margin, about a 6x markup over AI costs, 0% churn in 11 months, and revenue that grows automatically with each customer's call volume.</p><p>The only missing ingredient is distribution, and that is exactly where the leverage is. The product, billing, integrations, and multilingual marketing site require zero additional investment, so every dollar and hour goes directly into acquiring customers. Each new customer costs almost nothing to serve and lands at 85%+ margin. A buyer with an existing audience, an agency client base, or basic outbound capacity can scale MRR multiples from day one: the target verticals (hotels, online schools, e-commerce) are easy to reach, telephony provider ecosystems (Binotel, Ringostat, UniTalk) offer natural partnership channels, and the site is already localized for the Polish and EU markets. With this margin profile, customer acquisition converts to profit almost one-to-one.</p><p><b>Startup assets</b></p><p>Everything is included in the sale, with nothing held back:</p><ul> <li>Full source code: backend (FastAPI), customer app, admin panel, and marketing website (2 repositories, pnpm monorepo plus the site)</li> <li>Live production deployment with 2 active paying B2B customers generating $160+/mo</li> <li>.co domain, brand, and the multilingual marketing site (UK/EN/PL/DE) with SEO landing pages per industry, blog, and help center (Directus CMS)</li> <li>Admin panel with billing, tariff and markup management, payment requests, and usage analytics</li> <li>Working integrations: 3 telephony providers, 2 CRMs, Google Sheets, Slack, Telegram</li> <li>Customer accounts and historical call-analysis data accumulated since September 2025</li> <li>Developer documentation (dev-docs, ADRs, deployment and migration guides), written for handover</li> <li>Existing customer relationships, transferred with a warm introduction.</li> </ul> <p><b>Risks</b></p><ul> <li>Small customer base. Revenue is concentrated in 2 accounts. Mitigation: both customers have been stable for 11 months with 0% churn, their usage is growing, and the margin structure means each new customer a buyer adds is almost pure profit. The risk is concentration, not product quality.</li> <li>AI provider dependency and pricing changes. Mitigation: multi-provider adapter architecture (4 STT + 3 LLM providers) lets you switch providers per service in configuration, with no code changes.</li> <li>Market concentration in Ukraine. Mitigation: the site is already localized for PL/EN/DE, and telephony adapters are pluggable for EU providers.</li> <li>Solo founder knowledge transfer. Mitigation: extensive developer documentation in the repositories, and the founder includes 1-3 months of post-sale support for handover, deployment, and customer transition.</li> </ul> <p><b>Summary</b></p><p>The platform is a finished, revenue-generating vertical AI SaaS in one of the clearest AI use cases: call QA plus post-call automation. You are not buying a prototype or a promise. You are buying a production system that has run continuously for 11 months, with 2 paying B2B customers, 0% churn, an 85.9% gross margin, only $23/mo in AI costs, and a usage-based model where revenue grows automatically with customer activity. The integrations that take months to build (telephony, CRMs, messengers, billing) are done, the marketing site is localized for EU expansion, and the growth playbook is completely untouched: $0 has ever been spent on marketing. At $10,000 you get proven unit economics and a competitive, finished product, so every dollar and hour you invest goes straight into distribution, and at these margins, straight into profit.</p><p>✅ $2,000 TTM revenue</p><p>✅ 2 customers</p><p>✅ Business model: Pay-as-you-go</p><p>✅ Built with Docker, PostgreSQL, Fast API</p>
