Entrepreneur Anupam Mittal said he became a multi-millionaire in his early 20s, but lost everything when the dot-com bubble burst in 2000s and got into debt. Recalling his life in US, he wrote on LinkedIn, "Back then, I was riding high...I even ordered a Ferrari." However, Anupam said he returned to India in 2003 and started a dot-com venture Shaadi.com.
