Mumbai: United States (US) private equity firms Carlyle Group and General Atlantic are in talks to jointly invest about $150 million to $200 million in India’s online retailer Flipkart, two sources familiar with the matter told the news agency.

The two private equity firms will pick up a minority stake in Flipkart after their investment, said the sources, declining to be named as the talks are not public yet.

Flipkart is India’s biggest online bookseller, with over 10 million titles distributed from warehouses in five cities. It also sells mobile phones, appliances, gaming consoles, music and movies.

It generated $11 million in sales last financial year, and expects revenue to cross $100 million this year. It is targeting $1 billion in revenue by 2015.

Bangalore-based Flipkart had earlier raised $31 million in funding from US venture capital firms Tiger Global Management and Accel Partners, which has a stake in Facebook.
