Chegg, The Student Hub, has agreed to acquire InstaEDU, an on-demand tutoring marketplace, for $30 million in cash.

InstaEDU claims to be the world’s top online tutoring service. It connects students with tutors from top universities, combining the convenience of working online with the quality of in-person tutoring.

On InstaEDU, students can get last-minute help, do regular lessons throughout the semester, or connect when a quick question arises during an assignment. Individually screened tutors cover more than 2,500 subjects, ranging from basic subjects to AP material to advanced college courses.

Chegg believes the acquisition will be beneficial to earnings as early as 2015 and expects the acquisition to close by the end of June 2014.

“Students have been coming to Chegg for years to get homework help using our Chegg Study service when they've been stuck on a subject or need help mastering a concept. Now, they'll have the ability to connect any time, day or night, with an expert tutor who can provide personalized assistance on practically any subject,” said Dan Rosensweig, chairman and CEO of Chegg, in a statement.

Rosensweig said that on-demand tutoring, anytime, anywhere, on any device is a very disruptive idea, and it's about time that high-quality tutoring was made affordable and accessible for all students through technology.

Chegg puts students first and is proud to have saved students and their families more than $450 million in 2013 alone. As the leading student-first connected learning platform, Chegg’s Student Hub makes higher education more affordable and more accessible, all while improving student outcomes.

“We started this business because we recognized the opportunity to bring greater efficiency to a $60 billion global market through technology that makes one-on-one tutoring fundamentally more affordable and accessible for students anywhere,” said Alison Johnston Rue, CEO of InstaEDU, who is staying on to lead Chegg's tutoring business.

Rue said that combining with Chegg instantly gives the company’s on-demand tutoring platform access to Chegg's network of 13 million high school and college students.

“Together we can move quickly to reduce the cost of learning and improve grades and graduation rates across the board,” she said.
