In a clear indication that India dominates the world’s outsourcing business, a Forbes magazine survey says that five of the seven billionaires whose primary source of wealth comes from outsourcing happen to be Indians.

Nadar’s net worth is $3.9-billion. HCL Technologies, which he co-founded, is an outsourcing electronics, computing and IT software company.

"With clients like Cisco, Boeing and IBM, HCL is one of India’s leading global IT services companies that emphasizes ‘transformational outsourcing’, or working with clients to re-define the cores of their businesses," Forbes wrote.

Narayana Murthy, worth $1.4-billion, is now non-executive chairman of Infosys, a software services company he co-founded with only seven people and $250. Infosys is now a global leader in IT and consulting.

"Infosys pioneered the global delivery model of outsourcing. The premise is to take work to the location where the best talent is available; this philosophy helped stimulate the rise of offshore outsourcing and, of course, added to the company’s wealth," the magazine reported.

Nilekani, who has a net worth of $1.1-billion, is also a co-founder of Infosys and ran the company as chief executive and managing director until June 2007, when he became co-chairman.

Gopalakrishnan, with a net worth of $1 billion and another Infosys co-founder, was president and chief operating officer of the company until last June when he took over from Nilekani as chief executive and managing director.

Terry Gou, who is worth $6.1 billion, is chairman of Hon Hai, which assembles iPods, cellphones and game systems.

Barry Lam (worth $1.3-billion) runs Quanta Computer, the largest notebook original design manufacturer. Clients include Apple, Hewlett-Packard and Dell.

All seven made their billions through a phenomenon called offshore outsourcing, a combination of outsourcing and offshoring.
