The acquisition will be closed in the fourth quarter of 2013.

Online retail giant Amazon has acquired TenMarks, a mathematical education company founded by entrepreneur Rohit Agarwal, in a deal that adds to the clutch of Indian-led technology firms that have been bought out by their bigger American counterparts in recent times.

Mr. Agarwal’s previous venture was TechTribe, an India-focussed tech networking site that was backed by Canaan Partners, but shut down in 2009 due to funding-related issues.

While the financial details of the TenMarks’ acquisition were not disclosed, the company clocked a sizeable turnover last financial year, according to industry insiders.

The acquisition will be closed in the fourth quarter of 2013.

TenMarks, which is based out of California and was initially backed Catamount Ventures and Birchmere Ventures, focuses on helping to maximise teacher effectiveness in the classroom with an emphasis on mathematics.

“TenMarks’s award-winning math programmes have been used by tens of thousands of schools, and Amazon engages with millions of students around the world through our Kindle ecosystem," said Dave Limp, Vice President, Amazon Kindle, in a statement.

“Together, Amazon and TenMarks intend to develop rich educational content and applications, across multiple platforms, that we think teachers, parents and students will love,” Mr. Limp added.
