Start on Discord
Join the Discord. This is where the buildathon really begins:
introduce yourself
show what you've built
find your team
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.
