Overview

<p><b>Startup description</b></p><p>My app is a freemium document intelligence app for iPhone, iPad, and Mac. It uses on-device AI to summarize, compare, and extract structured insights from contracts, invoices, meeting notes, and research papers — with no cloud uploads and no account required. I built it as part of a 30+ app portfolio to give Apple users private document AI for sensitive files they can't send to cloud services. It's live on the App Store with active subscribers.</p><p><b>Key highlights:<b></b></b></p><ul> <li>Annual revenue: ~$6 TTM (early stage, launched recently)</li> <li>Annual profit: ≈ revenue — operating cost is $99/yr (Apple Developer Program), no servers or API bills</li> <li>Business margin: ~100% after Apple's commission (on-device AI = zero per-user cost)</li> <li>Conversion: 10% D1, 10% D7, 12.5% D35 download-to-paid</li> <li>Discovery: 483 impressions, 2.31% organic conversion, zero marketing spend.</li> </ul> <p><b>Team</b></p><p>Solo founder/developer (senior iOS/macOS engineer, 30+ shipped apps). Design, development, ASO, and App Store operations are all handled by one person. No employees or contractors — no ongoing obligations transfer with the sale.</p><p><b>Tech Stack</b></p><ul> <li>Swift / SwiftUI — full app across iPhone, iPad, and Mac from one codebase</li> <li>On-device AI (Apple Foundation Models / offline LLM) — summarization, comparison, extraction; no API keys, no per-document cost</li> <li>CloudKit — sync/storage; no backend servers</li> <li>StoreKit 2 — subscription infrastructure, live and configured</li> <li>Minimal third-party dependencies.</li> </ul> <p><b>Marketing and growth</b></p><p>No marketing has been done. All 483 impressions and every download are organic App Store discovery. That's the honest state and the opportunity: a 12.5% D35 conversion with zero ASO, content, or paid traffic means the funnel converts and has never been fed. Untapped levers: ASO for high-intent terms (contract summary, invoice reader, document AI), a Product Hunt launch, legal/finance-niche content, and localization.</p><p><b>Revenue and profit</b></p><ul> <li>MRR: $2 (1 active subscription)</li> <li>TTM revenue: $6; 3 total in-app purchases</li> <li>Profit ≈ revenue (only cost is the $99/yr developer account)</li> <li>Retention cohorts: D1 10% / D7 10% / D35 12.5% download-to-paid</li> <li>No refunds to date</li> <li>CAC: $0 (100% organic); LTV/churn not yet statistically meaningful at this volume.</li> </ul> <p><b>Startup assets<b></b></b></p><ul> <li>Full Swift/SwiftUI source code — iPhone, iPad, and Mac, git history included</li> <li>App Store Connect app transfer — approved, live, transfer-eligible</li> <li>1 active paid subscription (transfers with the app)</li> <li>StoreKit 2 subscription products, configured</li> <li>ASO assets — keyword research, screenshot sources, description files</li> <li>30 days post-transfer technical support from me</li> <li>No email list, no social accounts, no separate user database — what's listed is what exists (nothing hidden)</li> </ul> <p><b>Risks</b></p><ul> <li>Early revenue on small volume — mitigated by replacement-cost pricing; you're buying a finished, cross-platform product (~300+ hrs of senior dev work), not cash flow.</li> <li>Traffic-dependent — 100% organic today; ASO, Product Hunt, and paid channels are all untouched upside, not repairs.</li> <li>Platform risk (Apple-only) — mitigated by first-party frameworks, full App Store compliance, and privacy positioning aligned with Apple's direction.</li> <li>Competition from cloud document AI — mitigated by the on-device guarantee, which cloud-based tools structurally cannot match for privacy-sensitive users.</li> </ul> <p><b>Summary</b></p><p>My product is a finished, App Store-approved, on-device document-AI app running on iPhone, iPad, and Mac — converting at 12.5% by day 35 with zero marketing and effectively zero operating costs. You're buying a privacy-first product in a rising category for roughly the cost of building it, with every growth channel still untouched. For a buyer with distribution in legal, finance, or prosumer productivity, this is a proven-converting funnel that has simply never been given traffic. The hard part — a compliant, cross-platform, AI-featured product with paying users — is already done.</p><p>✅ $6 TTM revenue</p><p>✅ 1 customer</p><p>✅ Business model: SaaS</p><p>✅Built with Swift, SwiftUI</p>

Business Model

Freemium with an auto-renewable subscription. Free tier covers core document summarization. Premium unlocks document comparison, structured data extraction, and unlimited processing.

Target Audience

Professionals who handle sensitive documents and can't or won't upload them to cloud AI services: legal (contract review), finance and accounting (invoice and statement processing), consultants and researchers (synthesizing reports and papers).

Asking Price Reasoning

Priced on replacement cost, not a revenue multiple.

Reason for Selling

Consolidating focus. I've shipped 30+ apps and I'm narrowing to my core product line — a native Mac creative suite and developer tools.

Growth Opportunity

The product converts; it has never been given traffic. Untapped levers, in effort order: ASO for high-intent terms (contract summary, invoice reader, document AI) which has never been done; a Product Hunt launch.

30 days free support from seller

Competitors

Cloud document-AI tools and PDF assistants — ChatPDF, Humata, adept-style contract readers, and the document features in general assistants like ChatGPT. Differentiation: (1) fully on-device — competitors upload your documents to their servers.

Tech Stack

Swift, SwiftUI.
