The textbook era is over. VC investment in sector-shifting EdTech innovations, like interactive classroom apps and web-based assessment tools, is mounting. Toronto-based startup Top Hat, under the leadership of CEO Mike Silagadze, is the latest to benefit: the company just netted a $22.5 million investment in a series C funding round, according to Bloomberg.

With its cloud-based interactive software that helps educators create and distribute academic content, Top Hat’s technology is currently used in 75% of the top 1,000 schools in North America. The rivals Top Hat’s taking on next? Traditional “overpriced” textbook publishers like McGraw-Hill and Pearson. Backers including Union Square Ventures, iNovia Capital, and Georgian Partners have put millions of dollars of confidence behind this savvy startup.

Once considered a risky venture, as TechCrunch reports, EdTech has captured the attention of investors and teachers, too. As EdTech Magazine reports, 84 percent of students, faculty, and administrators believe a digital shift will help them conquer classroom challenges.
