Edtech vendors and products are not in short supply in 2019. But reliable information on their use can be hard to come by. Clever, a San Francisco-based edtech company with numerous products, thinks they struck a solution with Clever Library, an online catalogue containing hundreds of tools, products, and courseware offerings for classroom use. On June 24th, they announced that 250,000 teachers had put it to use since launching one year ago. According to the company, these teachers have created over 9 million student accounts.
