The strength of your startup comes from how clearly you understand your customer

At eChai Ventures, our Unforgettable Lessons series brings together founders’ stories about the moments that shaped their journey. These are not just tales of wins or failures, but turning points that leave a lasting imprint on how they think and build.

For Dr. Trishala Punjabi, CEO of BharatMD, one such lesson came during her first venture, when she learned that traction alone does not equal success.

Here’s how she tells it:

When I started my first company, Medguru, I thought traction meant success. Within months, we had 20,000 medical students using our app across 300 colleges. I felt like I had cracked it. But as the months went by, the numbers told a harsher story: in two years, we had made just ₹2 lakhs.

I couldn’t understand it. Students said they loved the app. They told me it was useful, even essential. Yet when it came to paying, almost no one did. That disconnect frustrated me more than failure. It felt like I was running on a treadmill, moving hard but going nowhere.

It forced me to confront a truth I had overlooked: just because people need something doesn’t mean they will pay for it. True customer development is not about hearing “yes, this is great”, but about digging until you understand what they value enough to part with their money for.

When I carried this lesson into my second venture, everything changed. I approached customers differently, asking sharper questions, testing willingness to pay before building, and focusing only on what truly mattered to them. The result? I made the same ₹2 lakhs in just 15 days that had taken me two years before.

That contrast, two years versus fifteen days, is etched into my memory. It taught me customer development from the ground up. Along the way, I also realized how easy it is, when you’re just starting out, to be blinded by your own idea. You fall in love with it, assume others will too, and lose sight of reality.

I had to learn to be brutally honest with myself and test whether customers actually wanted what I was offering. I even rejected three ideas I was deeply in love with before I started BharatMD, because customer conversations showed me they wouldn’t work.

If you’re just starting your journey, I’d recommend reading The Mom Test. It helped me ask the right questions and separate real signals from polite encouragement.

The most unforgettable lesson I’ve learned is this: the strength of your startup doesn’t come from how much you believe in the idea, but from how clearly and honestly you understand your customer.
