BazaarLive: Live Video Auctions for India's $16B Collectibles Market – Built for H0 Hackathon

Sakshi Kesarwani built BazaarLive, a live video auction platform for India's $16 billion collectibles market, during the H0 Hackathon. The platform uses LiveKit for streaming, WebSocket bidding with sub-500ms latency, Razorpay payments, and two AI features for item descriptions and auction summaries. It targets 45 million individual sellers and 100 million unserved users with zero competitors in the space.

India Has ZERO Live Auction Platforms. I Built One. Imagine selling a ₹50,000 Banarasi silk saree to a buyer in another city. You show it on WhatsApp photos no trust . They ask for details no video . You negotiate for hours no real-time . Indian collectibles market = $16 billion . Individual sellers = 45 million . Unserved users = 100 million . First-mover = 0 competitors . This is the opportunity. I built BazaarLive – the Indian Whatnot – for H0: Hack the Zero Stack. What I Built BazaarLive is live video auctions for India's collectibles market. Sellers go live via camera, showcase silk sarees, antiques, or jewelry in real-time. Buyers watch, bid instantly, and win via secure Razorpay payments. I use enterprise video streaming LiveKit , real-time WebSocket bidding sub-500ms with OCC conflict resolution, 2 AI features AI item descriptions and AI auction summaries , and AWS infrastructure S3, DynamoDB, DSQL, IAM . 10% platform fee on every transaction. First-mover India. Production-ready with real payments and order tracking.
