The eChai Effect - In Their Words

"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.

"I attended my first eChai event 3 yrs back, and no one knew me in the market. Over the next three years, eChai didn’t only help me with knowledge or networking, but it gave me an identity from being unknown to now being recognized by a group of inspirational entrepreneurs connected with eChai, who have been gracious enough to acknowledge me and Digipple."

“I have no hesitation in saying that my association with eChai has been a gateway into the startup ecosystem. Through this platform, I’ve had the opportunity to connect with many young and dynamic entrepreneurs. These interactions have been immensely enriching - I’ve learned a great deal and have always tried to offer guidance whenever approached. It’s a truly symbiotic relationship that I deeply value, and it wouldn’t have been possible without eChai.”
