The eChai Effect - In Their Words

"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."

The community has become like a second family to us, providing support, guidance, and valuable insights as startup entrepreneurs."

"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."
