about this event
150 builders. One day. Agents that move real money. Build an agent with Sarvam AI's Indian-language models and Cashfree's payment APIs. It hears what someone needs in Hindi, Tamil, Kannada or Bengali, and then actually moves the money. Demo it live by evening.
📅 Sat, 21 November 2026 · 11:30 AM – 7 PM 📍 Cashfree Office, Ecoworld, Bengaluru 👥 150 builders · 30 teams of 5 · in person 🏆 ₹3,00,000+ in cash and credits, shared across the top teams 🎁 500 Sarvam credits for every registered builder
Start on Discord — join the Discord. This is where the buildathon really begins: introduce yourself, show what you've built, find your team, and ask the Cashfree and Sarvam engineers anything. Who we select has a lot to do with who shows up here.
You build the agent in between. Someone says what they want, your agent does it, the money moves, and the agent answers back. Voice, chat, documents or WhatsApp.
What you walk away with ⚡ A working agent, built in one day, with Cashfree and Sarvam engineers in the room 🏆 ₹3,00,000+ in cash and credits for the top teams 🔑 500 Sarvam credits for every registered builder 📣 Winners featured on our LinkedIn 🍱 Food and coffee 🧢 Merch for everyone who ships
