Omidyar Network, an existing investor, has also participated in the latest round.
"The amount which has been raised will be used for product development and hiring new talent," Indus OS CEO & co-founder Rakesh Deshmukh told PTI.
The company would also invest in language technology to cover all Indian languages. Indus OS supports 12 Indian languages at present.
Earlier, Indus OS had raised USD 5 million funding led by Omidyar Network and angel funded by Kunal Bahl and Rohit Bansal from Snapdeal, Amit Gupta and Naveen Tiwari from Inmobi and Pranay Chulet from Quikr, according to the company.
Indus OS will soon be opening an office in China to further its efforts to partner with international smartphone brands.
