The eChai Effect - In Their Words
“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."

"If there’s one phrase that sums up my journey, it’s truly ‘The eChai Effect.’ Six years ago, I simply walked into my first eChai event, not knowing what to expect. The honest conversations, energy, and inspiration from founders and entrepreneurs struck a chord within me. That eChai spark became the catalyst for everything to follow. I proudly say: my entrepreneurship journey started—and keeps evolving—because of eChai. Redicine Medsol’s story is integrally linked to this community. I’ve gained so much, not just as a founder but as a forever volunteer and grateful member of the eChai family. With all my heart, thank you Jatin Bhai and everyone at eChai for shaping, guiding, and supporting my dreams. The eChai Effect will always be a part of my story."

“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.”
