How to Apply

1.Match your stage: most listed accelerators want a working PoC or MVP (TRL 3–6). Pre-idea founders are rarely a fit.
2.Watch cohort windows — accelerators select in batches. The weekly digest tracks every opening and closing.
3.Applications are form + pitch deck. The deck matters more than the form — spend time on problem, traction, and impact.
4.Check the program fee: most are free or grant-funded, but a few charge participation fees. It’s always stated on the funder page.

Frequently asked questions

Do climate accelerators in India take equity?

It varies. The programs listed on climategrants.in are accelerators with non-dilutive grant components (no equity for the grant portion). Some accelerators offer optional follow-on investment on separate terms — read the funder page.

What’s the difference between an accelerator and a grant?

A grant gives money for a specific project. An accelerator gives money PLUS a structured program — mentorship, pilots, workshops, investor access, demo day — usually lasting 3–8 months. The non-dilutive grant inside an accelerator is often larger than standalone grants.

When do accelerator cohorts open?

Most run 1–2 cohorts a year with fixed application windows. The weekly digest on this site tracks every opening and closing.
