India Climate Founder Communities
The real, active places where Indian climate founders gather: Telegram, WhatsApp, Discord, Slack and in-person. Every join link verified live. Nothing here is marketing.
Funding is only half the founder journey. The other half is who you know: the group where someone shares a warm intro, the meetup where you find a co-founder, the Slack where a funder posts an RFP. This page maps those places, alongside the grants directory.
Every entry is checked live: the join link resolves and the community shows recent activity. If a community looks dead, it is not listed.
