Startup Name Qexur CA 2.0 (Dual-Market Indian &amp; European Financial AI + Air-Gapped Web &amp; Desktop Suite) Startup Description Qexur CA 2.0 is an offline-first, dual-platform financial AI suite engineered for Chartered Accountants (India), Tax Advisory Kanzleien / Steuerberater (Germany/EU), and International Financial Auditors. Financial audit practices handle strictly confidential client invoices, bank statements, and tax ledgers that cannot be uploaded to third-party cloud APIs (OpenAI/Anthropic) due to criminal confidentiality and strict statutory privacy laws (EU GDPR Art. 28/32, German § 203 StGB, and the Indian DPDP Act 2023). Qexur CA solves this by providing two form factors powered by the exact same zero-cloud, air-gapped privacy engine: <ol> <li>💻 High-Ticket Desktop Workstation (Tauri v2 + Rust): Runs local quantized GGUF reasoning models (Qwen-3.8 / Qwen-3.5 reasoning + GLM-OCR) locally on consumer CPUs or 4GB–6GB GPUs via an innovative LowVRAM hot-swapping engine.Native sub-50MB RAM footprint, background directory folder watchers, and hardware auto-profilers.</li> <li>Runs local quantized GGUF reasoning models (Qwen-3.8 / Qwen-3.5 reasoning + GLM-OCR) locally on consumer CPUs or 4GB–6GB GPUs via an innovative LowVRAM hot-swapping engine.</li> <li>Native sub-50MB RAM footprint, background directory folder watchers, and hardware auto-profilers.</li> <li>🌐 Zero-Install Web Browser SaaS (ca.qexur.me/app): Delivers a modern, instant-access web SaaS experience built with Next.js 15 &amp; React 19.Crucial Architectural Innovation: It is ALSO 100% AIR-GAPPED. Using multi-threaded client-side WebAssembly (WASM via Tesseract.js, PDF.js, and in-browser ONNX transformers), all OCR and parsing run inside the user's browser sandbox. Users can paste bills directly from WhatsApp or email (Ctrl + V) and export balanced workpapers in 2 seconds. Zero bytes ever leave the client's PC, resulting in exactly $0.00 server compute costs.</li> <li>Delivers a modern, instant-access web SaaS experience built with Next.js 15 &amp; React 19.</li> <li>Crucial Architectural Innovation: It is ALSO 100% AIR-GAPPED.
