The eChai Effect - In Their Words

"At DevX.Work, we’ve greatly benefited from our association with eChai. Their events and networking forums have connected us with high-potential startups, ecosystem leaders, and innovation-driven professionals — many of whom have become valuable partners, collaborators, and even clients. What stands out most is the openness and accessibility of the community — whether you're an early-stage founder or an experienced entrepreneur, eChai provides a welcoming space to learn, collaborate, and grow. It's more than just a network — it's a catalyst for real, collaborative growth. We’re proud to be part of the eChai community. Highly recommended for any organization aiming to grow within the startup space."

"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."
