While the financial details were not disclosed, the deal will see Toronto-based Top Hat add more than 400 labs and course materials to its interactive digital learning platform. (The Logic)

Talking point: The acquisition is part of Top Hat’s effort to bring “traditional publishers into the digital age.” The Inovia Capital-backed company was founded in 2009 with this goal in mind. In February, the startup raised US$55 million in Series D financing. Soon after, it acquired Nelson Education, Canada’s largest education publisher, and its 400 textbooks. This latest deal will see Bluedoor’s approximately 50-person team join Top Hat’s 401 employees, just as universities and schools establish remote learning models. Top Hat began offering a free version of its platform in April, and launched a free communication tool for students and teachers last month.
