Humari Gullak

I started this when I was 16, to teach school students about money.

  1. 2022

    Instagram

    It began as an Instagram page that explained money in plain words. I tried to make the reels funny and relatable, and at the same time informative and useful. I also wrote a few articles, on Bitcoin, inflation and mutual funds. The page grew to about 1,000 followers.

    Talks at companies

    I could see the likes and comments, but I couldn't tell whether anyone was actually learning. So I started giving talks at companies, where I could explain things face to face and answer people's questions. The biggest was for more than 150 people at ATMS, and another was at TBNG.

    We built a curriculum

    But the gap I started with was in schools, and to reach students properly I needed a curriculum. Nehal Kansara, a college finance professor, joined as our advisor and designed the lessons with me.

    The regional finals

    With the plan ready, I took Humari Gullak to competitions. In 2025 I pitched at the Entrepreneurs' Organization's Global Student Entrepreneur Awards, and made it to the regional finals. Standing in front of a table of entrepreneurs with something I had started as an Instagram page at 16 was the high point of Humari Gullak.
