The eChai Effect - In Their Words

"For me, eChai is a second home. I've been associated with it since the early days, when it was already setting a different tone for how startup communities could work. As a traditional business owner entering the new-age D2C space, eChai supported me in every direction. Over the years, it became my window to the startup world — and also gave me lifelong friends who continue to show up, for business and beyond."

"eChai has played a truly pivotal role in HummingBird’s journey — even before Day Zero. From ideation to establishment and into growth, it’s been a constant source of support. It connected me with incredible people who’ve become more than just friends. One of the biggest reasons I chose to stay in Ahmedabad is because of the eChai community. It has shaped my growth — both personally and professionally — in ways that are hard to articulate. Honestly, words fall short when I try to express what eChai means to me. I’m deeply thankful and forever grateful to eChai for being such an integral part of my journey."

"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."
