The eChai Effect - In Their Words

“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.”

"We found eChai to be a force multiplier throughout our startup journey. Through it, we connected with folks from DevX, Allevents, Plutomen, and more - many of whom became friends of IndiaBizForSale.com and even part of our clientele."

“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."
