The answer to this question is a bit complicated and depends on how you define "startup". upGrad was founded in 2015, so it is a fairly new company. However, it is a fairly large company with over 1000 employees and has raised over $170 million in funding. So it is not a small startup by most definitions.
That being said, upGrad does have a startup feel to it. The company is very innovative and is constantly trying new things. For example, upGrad was one of the first companies to offer online degree programs in India. The company is also very data-driven and is always looking for ways to improve its products and services.
So while upGrad is not technically a startup, it does have many of the characteristics of one.
