A handful of education companies including Chegg and Boxlight announced acquisitions this week.

Chegg Acquires WriteLab: Santa Clara, Calif.-based learning platform Chegg has acquired WriteLab, an artificial-intelligence-enhanced writing platform, for approximately $15 million in an all cash transaction, according to a statement.

“This acquisition will strengthen Chegg’s existing writing service, with the addition of new tools, features, and functionality,” the company noted in the statement.

Berkeley, Calif.-based WriteLab teaches students grammar, sentence structure, writing style, and aims to offer instant feedback to help students revise, edit, and improve their written work.

“Developing strong writing skills is essential for students while in school, and as they move into the workforce,” said Nathan Schultz, chief learning officer at Chegg. “WriteLab’s technology will enrich our existing writing service and their team brings deep linguistic expertise to Chegg.”

Added Matthew Ramirez, CEO and co-founder of WriteLab: “By becoming a part of the Chegg family, who shares our student-first mission, we will reach more students and accelerate our work to support learners all around the world.”

Boxlight Acquires Cohuborate: Boxlight Corporation, a provider of interactive technology solutions for the global education market, has completed the acquisition of United Kingdom-based Cohuborate—known as Cohuba—from a family trust of Tony Cann, founder of Promethean, according to a statement.

Cohuba is a developer of touch display technology for the education, business, and government markets. Boxlight acquired Cohuba for approximately $1.8 million through the issuance of 257,200 shares of common stock at a price of $7 per share, Lawrenceville, Ga.-based Boxlight noted.

“The transaction is part of our continued effort to supplement our organic sales growth with strategic acquisitions that accelerate our ability to distribute our solutions globally,” said Michael Pope, president of Boxlight. “Cohuba brings a seasoned sales and operational team and a strong network of reseller partners with decades of experience selling technology solutions into the United Kingdom.”

Effective immediately, the Cohuba sales team will begin distributing Boxlight’s Mimio interactive classroom solution suite to the education market throughout the United Kingdom. Boxlight also said it plans to relaunch the Cohuba brand later this year as its global business and government solution, complete with hardware and software solutions tailored to the specific needs of those industries.

Tynker Acquires Pythonroom: Game-based coding platform Tynker has acquired Pythonroom, provider of an interactive, web-based learning management system, according to a statement. Financial terms of the deal were not disclosed.

With Pythonroom, “Tynker’s platform now includes a new range of courses that serve high-school level educators and students, building on its strong coursework foundation for pre-K, elementary and middle school students,” Tynker noted.

“The addition of Pythonroom to our kids coding platform is a valuable asset for schools, educators and students who are looking to take programming skills to the next level in a fun, intuitive and engaging way,” Krishna Vedati, co-founder and CEO of Tynker.

Pythonroom “fits seamlessly with Tynker’s mission of making coding fun, accessible and appealing to students by meeting them where their interests lie—like flying drones or programming games and animations—while simultaneously providing them with the foundational tools they need to learn how to code,” Tynker added in the statement.

ASSIST Expands Content with Apex Learning: ASSIST Education and Apex Learning enhanced their partnership with the addition of adaptive content and digital tutorials into the ASSIST Integrated Education Management System for K-12 schools, according to a statement from the companies.
