The eChai Effect - In Their Words
"eChai is playing biggest role in my personal and professional life together. Its a community where i meet like minded people to share idea and learn from their idea. Even while playing cricket i learn something and i implement something new from that learning. Its my entry point for building network in different countries where my base is not established yet. Personally my only fun activity day in a week is eChai cricket and social."

"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."

"After moving back from the USA, eChai became my go-to space to learn how the Indian startup ecosystem works. It offered direct exposure to startup thinking and a community that openly shares business insights. What stood out was how easy it was to connect, learn, and grow through real conversations. As we built our IT hardware rentals business, eChai helped us find our niche and refine our path. Proud and grateful to be part of this amazing community."
