what this is
Calcutta AI Club is a community of people in Kolkata who build with AI and people who want to learn. It started as ten people around a cafe table comparing notes on what actually works. Now it's hundreds of members: students, engineers, designers, operators and founders. They show each other real work, and find people to build with and people to hire.
Sessions
Every week, in different parts of the city. Each session takes one topic: someone who knows it teaches, and everyone else comes to learn it.
Workshops and hackathons
Longer days for doing the work. A workshop to pick up a skill, a hackathon to build something with a team.
Socials and demo nights
Once in a while the room meets with no topic at all, or members show what they built and hear what the room thinks.
Free to join. Applications are read by hand, and most people hear back within the week.

know your cofounders
Sahil works in his family's export business for a living. Somewhere between the invoices and the follow-ups he realised AI could do half of it, and things escalated from there. The club started when he had one coffee with Swarnim and could not stop thinking about it. Since then his main job has been making things grow slightly slower than Swarnim wants. Believes a sharp room of ten beats a loud room of hundred.
Swarnim runs ChurroTech, a software agency that helps small businesses automate the boring parts, and Calcutta Run Club on weekend mornings. He was the other half of that coffee, and had said yes before the cup was finished. Since then his main job has been trying to make the club grow slightly faster than Sahil allows. Already knew how to get a room of strangers talking, which turned out to be most of the work.
Between the two of them, the club averages out to exactly one sensible founder.
