Another example could be "Kai Po Che!" (2013), which revolves around the lives of three friends who start their own business ventures on the side. The movie explores their relationships, ambitions, and the challenges they face.
One of the most iconic and highly-rated Hindi movies featuring a businessman is "The Lunchbox" (2013), directed by Ritesh Batra. While not exclusively focused on a businessman's life, it does involve a character who is a accountant (and thus could be considered a businessman in a broad sense) and explores themes of loneliness, connection, and the human condition.
