The eChai Effect - In Their Words
"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.

"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."

“When we launched LegalWiz.in back in 2016, concept of procuring legal and compliance services through a digital commerce platform wasn't as prominent in India. eChai played a significant role in providing the early adopters, and building significant positioning in the startup fraternity. Overtime, eChai grew to be a massive network of like-minded entrepreneurs and extended that benefit to all the members in a true "co-rise" spirit. I personally love to attend eChai events, learn from subject matter experts who share relatable and actionable insights and experiences. For startup journeys, it is so important to be surrounded by people who can add relevance, perspective, and push you to do better. Most importantly a group of people where you aren't being judged about things going right or wrong, but be a motivational force that keeps you going, yet keeping you in check. eChai is that place for me!”
