The round was led by Kleiner Perkins Caufield & Byers (KPCB). New investments from Mark Zuckerberg and Priscilla Chan and Women's Venture Capital Fund, and follow-on from the John S. and James L. Knight Foundation and Owl Ventures complete the round. Newsela will use these funds to accelerate its machine learning capabilities and expand its footprint to help more teachers, students and school districts with the most effective literacy learning tools, while also helping to get students more engaged with what they're learning.

In addition to leading the round, Kleiner Perkins Caufield & Byers' partner Brook Byers will join Newsela's board of directors.

'There are more than 20 million U.S. students who are not reading at grade level,' said Byers. 'Newsela is uniquely positioned to address that problem, since it leverages technological tools that can help all students achieve grade-level literacy. This will be critical in setting them on the right path for the rest of their educational and professional lives.'

Newsela builds reading comprehension with nonfiction that's always relevant: daily news. The platform publishes daily articles from top news sources like the Associated Press, Scientific American and Washington Post, adapts articles to five reading levels and attaches comprehension quizzes for each level. Now entire classes can participate in the same conversation by reading the same content, but at a level that's accessible to each student. Newsela keeps students engaged with quizzes that test critical thinking and close reading, and teachers and administrators can view results in a clear, visual format.

'We offer a meaningful way for teachers to provide current materials, include every student in the conversation and measure how students are doing,' said Matthew Gross, founder and CEO of Newsela. 'Our goal is to give teachers the best technology available to make reading exciting and important to each student in their classroom. We want to build a future where teachers can teach the way they dreamed of teaching -- with tools that transform education and make kids excited about learning.'

Doubling the number within the last year, Newsela is now being used by 70 percent of all U.S. public schools. It has tripled the number of teachers using the platform to 400,000, which includes educators specializing in all subjects, from science and social studies to art. As a result, there are now more than 4 million students who have read more than 57 million articles through Newsela (even reading 1.3 million articles over the summer while school was out).

'Newsela leverages technology to build literacy among the next generation of news consumers, while informing them about the issues that affect their lives,' said Ben Wirz, Knight Foundation director for venture investments. 'It holds great potential for driving engagement with the world for people everywhere.'

As a company, Newsela has grown significantly in the last year, with new offices opening in both New York and Silicon Valley. The team grew by 50 percent, with experts in computational linguistics and machine learning joining the team, while also adding former employees of Facebook and Google.
