About ShadowMask

Security AI gateway: local PII masking & AES-256 encryption for safe prompts.

Key Highlights Zero-Knowledge Engineering: Unique local-first architecture ensures PII never touches the cloud, solving the biggest legal hurdle for enterprise AI adoption. Double-Layer Encryption: Implements complex AES-256 database encryption and ephemeral in-memory vaulting for maximum data sovereignty. Modern Monorepo Stack: Built with Vue 3, TypeScript, and Prisma, offering a maintainable, "middle-developer" approved codebase that reduces buyer engineering risk. Rapid Market Entry: A turn-key MVP with ready-to-use Admin dashboards, audit logs, and document processing scripts—save months of development time. White-Label Potential: Ideal for rebranding as a specialized security gateway for legal, medical, or financial firms. Operations ShadowMask AI functions as a privacy middleware. It scrubs PII from PDFs/DOCX files and user prompts locally before they reach AI models. Revenue Model: Designed for a B2B SaaS subscription or a "Bring Your Own Key" (BYOK) licensing model. Maintenance: Minimal. Since processing is handled on the client-side (local device), server costs and GPU overhead are virtually non-existent. Customers The platform is built for regulated industries (Legal, Healthcare, GovTech) that are currently banned from using standard AI due to data leak risks. Acquisition: Best suited for LinkedIn outbound, security-focused forums, or listing on the AWS/Azure Marketplaces. Nature: B2B customers looking for high-trust, "zero-knowledge" compliance tools. Financials The business is currently 100% Bootstrapped and offered as a Pre-revenue MVP. Zero Burn Rate: Hosting and database are currently optimized for free/low-cost tiers. Growth: Value is in the Intellectual Property (IP). A buyer avoids the high cost of specialized security engineering by acquiring this proven technical foundation.

Next step: A buyer isn't just buying your current code; they are buying a technical head-start in the multi-billion dollar AI safety market. Since you've built the "Zero-Knowledge" foundation, the buyer can scale this in three major directions:<h3>1. The "Dynamic Routing" Upgrade</h3>Currently, the app masks data. A buyer can take this further by adding Model Intelligence:<ol><li data-list="bullet">Sensitivity Routing: The app could automatically detect if a prompt is "low risk" (send to GPT-4) or "high risk" (reroute to a local, on-premise model like Llama 3).</li><li data-list="bullet">Result: The buyer saves money on API tokens for simple tasks and ensures 100% security for complex ones.</li></ol><h3>2. Enterprise Team Management (B2B SaaS)</h3>While your core logic is local, a buyer can build a Centralized Policy Cloud around it:<ol><li data-list="bullet">Role-Based Controls: Admins could set global rules (e.g., "Always mask Social Security Numbers for the HR team, but allow them for the Finance team").</li><li data-list="bullet">Tamper-Proof Audit Vault: Moving the local logs into a cryptographically signed cloud vault for corporate compliance officers to review during SOC2 audits.</li></ol><h3>3. "Self-Correction" AI Features</h3>The buyer can leverage the "Middle Developer" clean code you've written to add:<ol><li data-list="bullet">Contextual Placeholder Swapping: Improving the logic so that when the AI responds with <code>[NAME_1]</code>, the app seamlessly swaps back the original name in the UI without it ever having touched the server.</li><li data-list="bullet">Regulatory Presets: Adding one-click buttons for "GDPR Mode," "HIPAA Mode," or "FINRA Mode" that pre-configure all masking regex and encryption rules.</li></ol>

Reason for selling

I am a full-stack freelancer. I specialize in the 'zero-to-one' phase of development—taking a complex idea and architecting it into a functional, secure product. Having successfully built the core zero-knowledge engine and encryption framework for ShadowMask AI, I am selling the asset to reinvest my time and capital into my next technical venture. I am looking for a buyer who can take this and finish(if needed) technical foundation.
