The eChai Effect - In Their Words

"eChai is playing biggest role in my personal and professional life together. Its a community where i meet like minded people to share idea and learn from their idea. Even while playing cricket i learn something and i implement something new from that learning. Its my entry point for building network in different countries where my base is not established yet. Personally my only fun activity day in a week is eChai cricket and social."

The community has become like a second family to us, providing support, guidance, and valuable insights as startup entrepreneurs."

"From late-night brainstorming over chai to early morning founder calls, eChai has been more than just a network for me; it’s been home base for ideas, impact, and inspiration. What started as a simple meetup years ago turned into a powerful movement, connecting founders, creators, and dreamers. I’ve had the privilege of seeing startups find product-market fit, marketers (like me) find unexpected collaborations, and most importantly, people finding their tribe. संगच्छध्वं संवदध्वं – Let us move together, speak together. It’s not just a verse from the Rigveda — it’s how Jatin and the entire eChai community truly operate. We don’t just network, we grow together. Forever grateful to be a part of the eChai Effect.
