MiAngel is building the cryptographic control plane that turns AI from compliance liability to verifiable asset.
Enterprises are deploying AI everywhere, but in healthcare, finance, and education, there's no way to prove it's safe. Today's AI lacks cryptographic governance — creating a $20B+ trust gap.

TAM: AI Governance + Digital Health + RPM
MiAngel is the only platform that integrates both layers: B2C Complete Digital Health Guardian (Guardian Life Companion™) powered by B2B cryptographic trust infrastructure (GMAI SDK/API). Dual revenue engines attacking a $45B+ convergent market.
Private history remains cryptographically locked without verified biometric/device attestation.
Deterministic context retrieval with verifiable 'why' — cuts costs, reduces hallucination.
Graded safeguards auto-shift tone or route to human support when thresholds breach.
Immutable, hash-linked records deliver HIPAA/GDPR/SOC-2 evidence out-of-box.
AI is exploding across healthcare, finance, and education — yet enterprises can't deploy it safely. MiAngel owns the convergence: AI Governance ($20B+), Digital Health ($17.5B), and Clinical RPM ($8B+). We're not competing — we're enabling.

From patent-protected MVP to category-defining platform — scaling Guardian Middleware AI from proven technology to global trust infrastructure.
We believe in transparency. Here are the key challenges we face and how we're addressing them.
Mental health apps face increasing regulatory scrutiny and potential liability risks.
✅ Mitigation:
Working with healthcare compliance experts, implementing robust disclaimers, and pursuing clinical validation partnerships.
Mental health apps typically have high CAC ($50-200 per user) and long payback periods.
✅ Mitigation:
Focusing on organic growth through community building, partnerships with therapists, and content marketing strategies.
Large tech companies and established platforms have significant resources and user bases.
✅ Mitigation:
We don't compete — we enable. GMAI is infrastructure, not an app. Our patent-protected middleware becomes the trust layer that enterprises license.
Healthcare providers and insurers require evidence-based validation for widespread adoption.
✅ Mitigation:
Planning clinical studies with university partners and pursuing FDA clearance for therapeutic features.
Mental health apps face 30-50% annual churn rates due to the sensitive nature of the service.
✅ Mitigation:
Building deep emotional connections through AI personalization and community features to increase engagement.
Dependence on expensive AI models with potential for hallucinations or inappropriate responses.
✅ Mitigation:
Salience-Weighted Recall cuts context costs deterministically. Risk-Aware Escalation prevents unsafe outputs. Model-agnostic architecture future-proofs against vendor lock-in.

Founder & CEO
Rafael Mas is a technologist with 25+ years in IT infrastructure and cybersecurity who single-handedly translated a vision for ethical AI into a patented architecture and a live, functioning MVP.
He architected and built the core Guardian Middleware AI™ (GMAI), demonstrating an unparalleled blend of technical mastery and product execution that de-risks the fundamental technology. With decades scaling secure systems in enterprise, finance, and cloud environments, Rafael built a reputation for solving complex problems under pressure.
During the pandemic, Rafael saw that AI was powerful but not trustworthy. Instead of waiting for someone else to solve it, he set out to build Guardian Middleware AI — the cryptographic control plane that authenticates, policy-binds, and audits every AI interaction.
MiAngel is not a startup. It's the foundational trust infrastructure for the Age of AI. A platform that proves AI can listen with empathy and demonstrate integrity, cryptographically.
Rafael leads with obsession for technical execution, verifiable ethics, and scalable trust. His approach:
""Solve the architecture. Ship the proof. Scale the standard.""
Join us in building the cryptographic foundation that turns AI from compliance liability to verifiable wellness asset. Patent-protected. MVP proven. Market ready.
