India-born IIT Delhi graduate Jyoti Bansal sold his application intelligence company AppDynamics to networking giant Cisco for $3.7 billion on Wednesday adding another Indian to the global list of billionaires.

Bansal’s Silicon Valley-based AppDynamics works with some of the world's largest companies to improve their software application and business performance.

“I wanted to build companies that would leverage the power of software to make a difference in the world. I brought that dream to Silicon Valley as a 21-year-old fresh out of college and AppDynamics for me was the beginning of fulfilling that personal dream,” Bansal said in an online blog post.

Bansal, who moved to US in July 2000, had to wait seven long years to begin his entrepreneurship journey due to complications in starting a business while being in the country on a H1B work visa.

“What is most frustrating about the green card process is you have no control over a major part of your life. I have friends who became frustrated with the uncertainty and after years of waiting they finally left the United States,” Bansal said in an interview with Forbes in March last year.

Nine years ago, in January of 2008, he was just a young software engineer with a dream and determination to start his own company, he said in a blog post on Wednesday.

“I spent my days making the rounds on Sandhill Road in Silicon Valley, trying to generate interest from venture capitalists. On nights and weekends, I sat on my couch in San Francisco and wrote code,” Bansal said.

Bansal’s efforts has made his company one of the most coveted start-ups in the Silicon Valley.

“The combination of Cisco and AppDynamics will allow us to provide end-to-end visibility and intelligence from the network through to the application; which, combined with security and scale, and help IT to drive a new level of business results,” said Rowan Trollope, Senior Vice-President and General Manager, Cisco's Internet of Things and Applications Business Group, while talking about Cisco's synergies with AppDynamics.

AppDynamics may be Bansal’s first entrepreneurial venture, but he’s worked with several start-ups, all of whom have been acquired by large multinationals such as Microsoft, Rockwell Automation and CA.

Sharing his experience in running start-ups, Bansal said, “In this journey of the last nine years, one of the most important things I learned is that you have to have a big dream, a big goal, and a big vision; but, you have got to implement it “one milestone at a time.” There will be stumbles — but you get up and keep going until you reach that next milestone.”
