Trishneet Arora, 25

Founder and CEO, TAC Security

Previous Rank :

Arora’s affair with technology began when his father, a tax consultant in Ludhiana, Punjab, brought home a computer. He was nine then. Arora, who would take apart appliances and gadgets to figure out how they worked, did the same with the computer, too. In February 2013, he launched TAC Security with ₹75,000 that his father gave him. He operated from home with two others. Within six years of its launch, Arora’s TAC Security is one of the most talked about startups in the world of cybersecurity.
