Codecademy raises $10 million in second financing round

The interactive coding course site had already raised $2.5 million in its first round of financing in November.

Codecademy, a site that helps users learn how to code for free, has raised $10 million in a second round of financing.

The company announced today that the round was led by Index Ventures and Kleiner Perkins. Those investment firms now join Unique Square Ventures and Virgin Group founder Richard Branson among the company's investors. Codecademy raised $2.5 million in its first financing round.

"With this new funding, we're going to keep doing what we've been doing," Codecademy wrote on its blog today. "We've reached millions of students in more than 100 countries. Tens of thousands of teachers who have created Codecademy courses are now able to spread their knowledge all over the world. We want to make that process better for our students and for our teachers."

Back in February, Codecademy announced that its Code Year initiative, designed to get people to learn to code in 2012, had been such a success that it attracted the attention of the White House. As part of its Summer Jobs+ program, the White House partnered with Codecademy to help both kids and adults to learn to code, reasoning that the partnership should help people find jobs.

So far, Code Year has attracted more than 450,000 students.
