Previous Milestone: ANGEL Public Progress Report (Q4 2025 / Module 3 Extension - December 18, 2025)
Reporting Period: February 2025 – April 2026
Project Duration: 15 months
Project Status: COMPLETED
Between February 2025 and April 2026, the ANGEL project successfully reached its final development milestone. The platform evolved from an initial concept into a fully consolidated, market-ready SaaS B2B application, accompanied by a comprehensive business plan and Go-To-Market strategy.
This final development phase—spanning Q1 2026 (January–March)—focused on completing the technical implementations, specifically the AI validation pipeline and end-to-end financial integrations, while consolidating all market research, unit economics, and regulatory frameworks into a cohesive business proposition.
ANGEL is now a fully developed fintech infrastructure product, purpose-built to solve the operational and compliance bottlenecks that plague corporate social investments in Brazil.
Objective: Automate invoice validation and supplier verification to eliminate manual document review bottlenecks.
Implementation:
- OCR/NER Pipeline: Finalized and integrated into the compliance workflow
- Automated Extraction: The system autonomously extracts and verifies:
- Supplier CNPJs (Brazilian tax IDs)
- Invoice amounts against approved budgets
- Line-item details and quantities
- Validation Logic: Functions with a configurable ±5% tolerance threshold
- Error Handling: Intelligent flagging system routes edge cases to human review with contextual annotations
Impact: Transformed manual document review (15–30 minutes per invoice) into automated validation in seconds.
The platform implements a 5-step core transaction lifecycle designed to ensure full traceability, regulatory compliance, and zero-trust payment execution:
- Mechanism: Corporate donors deposit committed funds into segregated escrow wallets via BaaS partners (Celcoin/Aarin)
- Compliance: Funds remain locked until NGO requests are validated and approved
- Key Benefit: ANGEL operates strictly as a software orchestration layer—no direct fund custody
- Workflow: NGOs submit funding requests through the platform, attaching:
- Supplier invoice (NFe PDF)
- Budget line-item allocation
- Project milestone documentation
- Data Structure: All submissions stored with TypeScript-enforced domain models
- Pipeline: OCR extracts invoice data → NER validates supplier CNPJ → Budget reconciliation
- Decision Engine:
- Auto-approve if all checks pass within tolerance
- Flag for manual review if discrepancies detected
- Auto-reject if fraudulent invoice detected
- Key Innovation: Funds flow directly from escrow to suppliers—bypassing NGO bank accounts entirely
- Fraud Prevention: Eliminates the primary vector for donation misuse
- Payment Rail: PIX instant payment protocol via BaaS partner APIs
- Hash Generation: SHA-256 cryptographic hashing of transaction metadata and validated documents
- Blockchain Layer: Polygon L2 (Layer 2 scaling solution)
- Verifiability: Public audit interface allows stakeholders to independently verify transaction integrity
Monorepo Strategy: The entire project was unified under a clean monorepo structure, enabling:
- Shared Type Definitions: Domain models defined once in TypeScript and consumed across frontend/backend
- Atomic Commits: Changes to business logic synchronized across both layers
- Developer Velocity: Hot module replacement, automated API mocking, end-to-end type safety
Technology Stack:
- Backend: NestJS (TypeScript)
- Frontend: React + Vite
- Payments: BaaS integration (Celcoin/Aarin), PIX protocol
- AI/ML: OCR/NER pipeline
- Blockchain: Polygon L2
- Database: Typed domain models across the stack
Primary Data Sources: GIFE (Grupo de Institutos Fundações e Empresas), IBGE (Brazilian Institute of Geography and Statistics), CVM (Securities and Exchange Commission)
| Metric | Value | Source |
|---|---|---|
| TAM (Total Addressable Market) | R$ 24 billion/year | GIFE, IBGE, CVM |
| Target Segment | 50–100 mid-sized enterprises | Market analysis |
| Revenue Range | R$ 50M–R$ 800M annual revenue | Customer profiling |
Target Customer Profile:
- Mid-to-large enterprises with structured ESG programs
- Companies lacking operational infrastructure for compliance and transparency
- Organizations facing pain points: manual invoice review, audit trail gaps, NGO accountability issues
Critical Requirement: ANGEL must operate as a software platform only—not as a financial institution—to avoid BACEN licensing requirements.
Compliance Strategy:
- BaaS Dependency: All fund custody, escrow management, and payment execution handled by licensed BaaS partners
- Platform Role:
- Orchestration layer coordinating API calls to BaaS providers
- Compliance engine validating documents and enforcing business rules
- Audit infrastructure recording transactions on blockchain
Key Regulatory Wins:
- No direct fund custody (eliminates BACEN licensing barrier)
- BaaS partners handle all financial operations
- Blockchain audit trail ensures transparency
- Software-only model validated for regulatory compliance
Revenue Model: Hybrid SaaS Subscription + Transaction Take-Rate
Financial Projections:
- Average ARPU: R$ 2.740/month (Growth tier)
- LTV/CAC Ratio: ~4x (healthy SaaS benchmark)
- Break-Even Point: 9–15 active clients
- Model: Highly scalable hybrid approach combining recurring revenue with transaction-based fees
Key Metrics:
- Strong unit economics validated through market research
- Scalable revenue model supporting long-term growth
- Break-even achievable with modest customer acquisition
