Veteran investor and Sorin Investments Founder Sanjay Nayar said 'Unicorn' is "just a buzzword" and it cannot be the end goal. "You have to build a real business, a sustainable business, a profitable business...the valuations will sort of follow," he said on the sidelines of the Startup Mahakumbh. Unicorn is a startup company whose valuation has crossed $1 billion.
