Indian start-ups valued at more than $1 billion, known as "unicorns," have multiplied in recent years. Goldman attributed this to the internet ecosystem's fast expansion, as well as the increased availability of private financing and a more favorable regulatory structure.

According to the bank, there are at least 67 Indian private start-ups that meet the criteria of a unicorn, with 27 estimating that they would be valued at $1 billion or more by 2021. Their main concern is the digital economy in India.
