🧭 The Problem We're Solving

Indian farmers lose ₹92,651 Crore annually due to:
┌────────────────────────────────────────────────────────────┐
│  🔴 Middlemen taking 40-60% of actual sale price           │
│  🔴 35% crop loss due to undetected diseases               │  
│  🔴 No access to real-time mandi prices before harvest     │
│  🔴 Agricultural experts unreachable in rural areas        │
│  🔴 Information asymmetry exploited by traders             │
└────────────────────────────────────────────────────────────┘

KrushiSetu fixes ALL of this in ONE platform.
