Karti has business in his genes.
The Chettiars are a trading caste in Tamil Nadu.
Karti's ancestors went as far afield as Myanmar, Malaysia and Singapore to do business. They also learnt philanthropy, public service, leadership and business values.
Tamil Nadu is dotted with choultries (as dharamshalas are called), hospitals, schools, stadia and other public facilities built on land donated by Chettiar families.
In fact, when Karti was getting married, the wedding dates had to be juggled because the hall was available only on a few dates, "even though it is owned by our family", his father confesses with a wry laugh.
Karti was an only child, born to privilege, something he readily accepts.
"Life was very easy and comfortable growing up. It continues to be so," he says.
