Starting my own business wasn’t the result of one make or break moment–it was the result of three. I was raised in a traditional rural town in India and forbidden to speak (or even make eye contact) with men. I went to school with all women, some of whom were dropping out for arranged marriages as early as 13 years old. But I had a different plan for my life. I studied hard and became the first woman from my town to get accepted into the Indian Institute of Technology (IIT) for computer science. After graduation I was faced with my first make or break moment: stay in a traditional arranged marriage or move to the United States to pursue my dream of becoming a software developer? I decided to move to the U.S. It was one of the best decisions I’ve ever made—and the first step I needed to take in order to start my own business.

I accepted a job offer at Facebook and was inspired by a talk Sheryl Sandberg gave about the barriers women face in the workplace. This was critical moment number two. Despite having no money and being newly divorced, I decided to leave all of my pre-IPO Facebook options on the table and went to Stanford Business School. I was determined to get the education I needed to start my own company.

At Stanford I set out to form my own venture. I searched for a co-founder, but couldn’t find the right fit. I considered partnering with classmates on their start-ups, but those start-ups were their dreams–not mine. It wasn’t until a classmate said, “You can do this alone” that I realized I really was capable of launching a business by myself. I had done everything else on my own up until this point, so why would this be any different? This was critical moment number three.

Before I graduated business school, (which I barely did because I failed an entrepreneurship class due to time spent building my business) I had already closed my first round of funding. Each one of these critical moments pushed me to work harder, ultimately leading me to fulfill my dream–creating my own company.
