Tata Sons, the holding arm of India's largest private sector group, has started expanding the operations of their business process outsourcing (BPO) company after a quiet entry into the segment last year.

The group's 100 percent outsourcing subsidiary, E2E SerWiz Solutions, is based in Pune, with contact centres in Hyderabad, Mohali, Kolkata and Coimbatore. The company has a staff of 4,000 employees at present.

"We had started the BPO operations with 300 employees who were recruited from two group companies - Videsh Sanchar Nigam Limited and Tata Teleservices - to cater to the needs of our telecom businesses," said a Tata official.

"We now want to expand the operations and emerge as one of India's top three BPO players in the next two years with a target of employing around 10,000 associates," the official told.

The company earned revenues of $116 million in the first year of operations and has earmarked Rs.2.5 billion ($55 million) for expansion, the official said.

E2E SerWiz Solutions provides customer contact services in a host of languages including English, Hindi, Telugu, Marathi, Kannada, Tamil, Gujarati, Malayalam and Punjabi and handles over nine million transactions per month.

Global companies like Microsoft Nortel, Cisco, Nice, Blue Pumpkin and Verint are some of its partners.

The company recently hired Nagabhushana Rao, a former employee of Siemens and Standard Charted non-banking finance companies, as chief executive officer of E2E SerWis to scale up the outsourcing business.
