💡 The Problem

India's 12 million gig workers lose ₹50,000 crore annually to weather disruptions, platform outages, and health emergencies. Yet 95% have zero insurance because traditional insurance requires:

• 7-14 days claim processing
• Complex paperwork (barrier for low-literacy workers)
• High premiums (₹500-2000/month)
• Manual verification and disputes

GigShield solves this with parametric insurance that auto-triggers payouts in 2 hours—no paperwork, no disputes.

• 🤖 AI Fraud Detection - 7-signal Behavioral Coherence Score (85% accuracy)
• 💰 2-Hour Payouts - Razorpay UPI integration
