Unicorns may be mythical beasts in the animal kingdom but in Indian business, they are becoming more and more common. The unicorn here is not a fabled horse with a horn on its head but refers to a specific type of company. To those unaware, a unicorn is a start-up company which surpasses a $1 billion valuation. The term was coined in 2013 by venture capitalist Aileen Lee as it refers to the statistical rarity of this happening.
