"Recommending interventions" is a piece of what Knewton does. But we don't need PII or demographic data to do it. We are integrated with the digital course materials (Pearson, Houghton Mifflin Harcourt, Cengage, etc.) and work inside those products to provide real-time student recommendations, predictive analytics for teachers (intervene ahead of time), and content insights for publishers to change content or create more where it's needed most.
