The eChai Effect - In Their Words

"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."

"From late-night brainstorming over chai to early morning founder calls, eChai has been more than just a network for me; it’s been home base for ideas, impact, and inspiration. What started as a simple meetup years ago turned into a powerful movement, connecting founders, creators, and dreamers. I’ve had the privilege of seeing startups find product-market fit, marketers (like me) find unexpected collaborations, and most importantly, people finding their tribe. संगच्छध्वं संवदध्वं – Let us move together, speak together. It’s not just a verse from the Rigveda — it’s how Jatin and the entire eChai community truly operate. We don’t just network, we grow together. Forever grateful to be a part of the eChai Effect.

"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."
