Mr. Zeitz's deep love for Africa pushed him to open Segera, a 50,000-acre conservation reserve in northern Kenya with an award-winning eco-safari lodge, since 2005.

He also co-founded the Zeitz Museum of Contemporary ArtAfrica (Zeitz MOCAA) in Cape Town, which was opened by Archbishop Desmond Tutu in 2017.

He got his big breakthrough when he was 25. Raj was able to sell more than 160 retail stores in Singapore.

In an interview with wealth report, Raj alias Singapore King noted that he is currently not working for money but rather wants to spend the next five years locating individuals who are business talented but lack financial support.
