Overview
<p><b>Startup description</b></p><p>My product is an offline-first, AI-powered desktop application built specifically for Chartered Accountants (CAs) and financial auditors. Financial professionals deal with highly sensitive data (invoices, receipts, tax documents) that they cannot upload to cloud APIs like OpenAI due to strict privacy laws.</p><p>It runs powerful Large Language Models (GLM-OCR and Qwen) entirely locally on the user's machine. It automates data extraction and prepares it for Tally/ERP software, saving hours of manual entry without ever compromising client data.</p><p><b>Key Highlights</b></p><ul>
<li>Annual Revenue: $1,800</li>
<li>,Annual Profit: $1800</li>
<li>Operating Costs: $0 (Zero API costs due to Local AI)</li>
<li>Key Feature: 100% offline data processing for extreme privacy.</li>
<li>Monetization Ready: Includes a built-in Hardware ID (HWID) DRM licensing system written in Rust, making it ready for commercial software distribution and anti-piracy protection.</li>
</ul>
<p><b>Team & Tech Stack</b></p><p>I am a solo founder and full-stack engineer. I developed the entire product architecture:</p><ul>
<li>Frontend: React, Vite, TailwindCSS (for a fast, intuitive UI).</li>
<li>Backend: Rust, Tauri v2 (for high-performance, native desktop execution).</li>
<li>AI Engine: Dual Local LLMs (GLM-OCR for layout extraction, Qwen-3.5 for reasoning and JSON structuring) featuring 'LowVRAM hot-swapping'.</li>
<li>Security: Custom Rust-based Hardware ID generation for DRM.</li>
</ul>
<p><b>Assets Included in the Sale</b></p><ul>
<li>Complete Frontend Source Code (React, Vite)</li>
<li>Complete Backend Source Code (Rust, Tauri v2)</li>
<li>Local AI Orchestration Engine Code (GLM & Qwen integrations)</li>
<li>Built-in Rust HWID Licensing System</li>
<li>UI/UX Assets and Logos</li>
</ul>
<p><b>Risks & Mitigation</b></p><p>The main risk is distribution. Since the tech is fully built and tested, the buyer needs to focus entirely on sales and marketing to Accounting firms. To minimize this, the buyer should ideally have an existing audience in the FinTech/B2B space or be willing to run targeted B2B outreach.</p><p><b>Summary</b></p><p>This is a rare opportunity to acquire a highly sophisticated, enterprise-grade Desktop AI application. Most AI apps today are just thin wrappers around OpenAI that cost money every time a user clicks a button. It runs entirely offline with an innovative 'LowVRAM hot-swapping' feature. You are buying months of complex Rust and AI engineering that you can brand and monetize immediately.</p><p>✅ $1,800 TTM revenue</p><p>✅ 6 customers</p><p>✅ Business model: LTD</p><p>✅ Built with TypeScript, JavaScript, TailwindCSS</p>

Business Model
B2B software licensing model. The new owner can sell lifetime hardware-locked desktop licenses (e.g., $499/license) or annual subscriptions to accounting firms. Since there are zero API costs to run the local AI, the profit margin per license is nearly 100%.
Target Audience
Chartered Accountants, financial auditors, bookkeeping firms, and freelance accountants who handle sensitive client financial data.
Asking Price Reasoning
The asking price is highly discounted for a quick sale. Building a Tauri v2 Desktop App with an integrated Hardware-ID (HWID) DRM system and a dual-model Local AI engine (GLM + Qwen with LowVRAM hot-swapping) requires months of expert-level Rust and AI engeneering.
Reason for Selling
I am a solo engineer and my primary expertise is building complex, deep-tech architectures (Rust, Local AI). I built this product to solve a real privacy problem for my local network of CAs, but I do not have the marketing skills, time, or sales team to scale.
Growth Opportunity
Since the software is fully functional and hardware-locked, growth requires launching B2B cold-email campaigns targeting accounting firms, listing on B2B software directories, or partnering with CA agencies to distribute the software as a privacy-focused solution.

Competitors
Cloud-based financial extraction tools like Dext, Hubdoc, or generic OpenAI wrappers. However, our key differentiator is 100% offline local AI processing, ensuring absolute data privacy for sensitive tax documents.
Tech Stack
TypeScript, JavaScript, TailwindCSS, Python, React, Rust.
