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."

"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."

"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."
