We have large educational clients that are integrating the tech because of its benefit for students (especially those with ADHD and dyslexia). IP licensing is great because it means I don't need to spend time building the integrations myself, and I don't have any costs attached to the licensing deals, so it's pretty much all profit. In 2020 the IP licensing will greatly exceed the B2C revenue, and we may even make the B2C tools free at that point.
