A bit more about me.

Where I come from, how I found product, and what I’m up to when I’m not working.

Delhi kid. Serial hobbyist. Product person, eventually.

I was born and raised in Delhi, and I’ve lived in the same city all my life. So I did my exploring sideways. I painted, played the keyboard and played basketball in the early years, and then picked up pretty much every sport going.

In undergrad I fell in love with solving problems. I just didn’t know which job that was. So I tried a bit of everything: venture capital, venture building, a few real estate startups, and roles across product, marketing and growth. I wanted to see where I actually fit. Product was the one that clicked.

During college I started Nest, an incubator for the stage before incubation, when an idea is still rough. I got to stand next to founders on their zero-to-one journey, and that made me want to try it myself. So I built Fitin with a couple of friends. It didn’t work out, so I exited. Not every story ends in a launch party, and I’m fine with that.

After college I joined Visit Health. That’s where I learned stakeholder management, building products from scratch, managing big teams, healthcare tech and thinking from first principles.

Outside work I listen to podcasts and read, mostly about people’s journeys: how they got from nothing to something.

ISB felt like the natural next step. I wanted a more structured way to keep learning, and a chance to meet people from very different fields and backgrounds, which speeds up the journey. After ISB, I want to build something for a much larger consumer audience. The rest I’m still figuring out.

At ISB

ISB, so far

Classes, podcasts, football nights and one very inconvenient fracture. Swipe through.

Off the clock

What I’m into

When the laptop is shut: board games, movie marathons with whoever is up for them, songs on repeat, trips and a bit of art. Drag anything around.

For the first time in history, taste compounds faster than code.

The non-technical founder’s unfair advantage

The work isn’t coding. The work is having a clear opinion about what the thing should feel like.

The non-technical founder’s unfair advantage

Find the design that serves all of them without being a compromise for any of them.
