🎯The Problem
Enterprise customers were spending 100+ hours weekly manually extracting data from invoices, contracts, and forms. Issues included:
- Error rate of 12% in manual data entry
- Processing delays causing downstream workflow bottlenecks
- High operational costs ($500K+ annually per large customer)
- No way to handle 10x document volume spikes
🔍My Approach
Designed 0-1 product for intelligent document processing:
1. **Customer Discovery**
- Shadowed 10 operations teams processing documents
- Identified 15 document types with highest volume
- Mapped current workflows and pain points
2. **Technical Feasibility**
- Evaluated OCR engines (Tesseract, Google Vision, AWS Textract)
- Tested NER models for entity extraction
- Prototyped with 1000 sample documents
3. **Product Strategy**
- Started with invoice processing (highest volume, clear ROI)
- Built template-free extraction (works on any format)
- Human-in-the-loop for quality assurance
- API-first design for easy integration
💡The Solution
Launched end-to-end ML document processing platform:
**Core Features**
- Multi-format support (PDF, images, scanned docs)
- Automatic field extraction using NER + custom ML models
- Confidence scoring with human review queue
- Validation rules and business logic
- Real-time API and batch processing
**ML Pipeline**
1. Document classification (identify document type)
2. OCR and text extraction
3. Layout analysis (tables, headers, line items)
4. Entity extraction (dates, amounts, names, addresses)
5. Validation and confidence scoring
6. Human review for low-confidence predictions
**Integration**
- RESTful API for real-time processing
- Batch upload via web interface
- Webhooks for async notifications
- Export to ERP systems (SAP, Oracle, Workday)

💭Key Learnings
- •Template-free was right bet - customers had thousands of document variations
- •Human-in-the-loop essential for trust - started with 30% review, now at 5%
- •Model retraining from corrections created flywheel - accuracy improved 8% over 6 months
- •Table extraction was hardest - complex layouts required custom models
- •API-first design enabled land-and-expand - integrations drove adoption
