I started Airboxr to help DTC founders and marketers make quick decisions without wasting time on creating and reviewing reports. 

Prior to Airboxr, I was at Entrepreneur First working with over 300 exceptional deep-tech founders and helped launch VC-fundable startups in AI, security, life sciences, and fintech. I also coach founders on problem identification, solution-building, market-sizing, customer development, financial-modeling, and fund-raising. 

I cofounded Overcart.com, an e-commerce marketplace and services platform with annual sales run rate of $8.5m and venture funding of $3.5m. As a product leader, I've launched four B2B and B2C products, including Overboxd.com - a platform to manage customer returns. As an ops leader, I expanded services and fulfilment operations to three Indian cities, launched India's first preowned-device warranty service (OverTrust), and grew the team to 230-members. As a revenue leader, I built a high-performing digital marketing team and reached traffic of 1.8m users/month, with less than 4% of sales spent on marketing.

Prior to founding Overcart.com, I spent seven years as a Management Consultant advising clients on emerging market entry strategies.

The eChai Effect - In Their Words

"eChai isn’t just a startup community … it’s a mindset . eChai has been one of the most impactful communities in my entrepreneurial journey. It’s been a turning point . In a world where building something can often feel isolating, eChai gave me a sense of belonging. I’ve found mentors, collaborators, and friends here — people who genuinely want to see you succeed. It’s a space where ideas are challenged, actions are celebrated, and founders grow not just in scale, but in clarity and confidence. From late-night ideas to early-morning pitches, this community has quietly but powerfully shaped the way I build, think, and dream. I’ll always be grateful for the way eChai creates spaces where founders don’t just grow businesses — they grow together."

“You don’t plan to build a company via eChai. You just keep showing up … and one day, you realize you did.” I’ve known Jatin since 2012, when I was still deciding what kind of second innings I wanted to play as an entrepreneur. Over the years, through events, chai breaks, intros, and seemingly small conversations, eChai helped shape not just Upsquare but also refined the lens through which we see collaboration. At Upsquare, we’ve hired talent, met partners, discovered co-investors, and built lifelong friendships. One of our joint ventures exists today only because a casual eChai memory sparked a deeper trust. Now, as we build House of Starts — our venture builder — eChai continues to fuel our mission: co-creating a shared future. eChai isn’t just a startup network. It’s a trust network. And for business builders like me, that makes all the difference."

“eChai has been that turning point in my journey. It gave me a platform when I wasn’t looking for visibility but needed direction. Over the years, it became more than just a network. It became my tribe; a place where conversations sparked collaborations, and strangers became trusted sounding boards. What I value most is how effortlessly eChai brings people together - no airs, no filters, just genuine people with shared dreams. I owe a lot to this community and to Jatin, whose consistency and belief in people have shaped journeys like mine. Forever grateful to be part of something so real.”
