The eChai Effect - In Their Words

"The eChai platform has been super valuable for me - it has helped me gain a deeper understanding of domains in the startup and tech ecosystem. What stands out most is the celebration of knowledge, professional growth, and entrepreneurship - it’s one of the best for the Indian ecosystem. Along the way, I’ve also been fortunate to make some great friendships and connections too."

"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.

“You don’t plan to build a company via eChai. You just keep showing up … and one day, you realize you did.” I’ve known Jatin since 2012, when I was still deciding what kind of second innings I wanted to play as an entrepreneur. Over the years, through events, chai breaks, intros, and seemingly small conversations, eChai helped shape not just Upsquare but also refined the lens through which we see collaboration. At Upsquare, we’ve hired talent, met partners, discovered co-investors, and built lifelong friendships. One of our joint ventures exists today only because a casual eChai memory sparked a deeper trust. Now, as we build House of Starts — our venture builder — eChai continues to fuel our mission: co-creating a shared future. eChai isn’t just a startup network. It’s a trust network. And for business builders like me, that makes all the difference."
