Ok, found a techcrunch article in case random perusers are interested --

Excerpt:
Seesaw also substitutes for managing huge stacks of paper. Beyond tracking each student separately, the new $120 per year Seesaw Plus premium version includes a skills view where teachers can rate students as green, yellow, or red on each lesson. A chart view both identifies students falling behind, but also which topics are giving the whole class trouble and might need a better lesson plan.
Seesaw Plus isn’t the startup’s main business model, though. It’s more of an infiltration technique for bottom-up sales to school districts. The Seesaw For Schools paid version gives administrators a dashboard to monitor each classes’ workbook and integrate the data into their grading software.
Seesaw is following the Dropbox playbook. Instead of top-down cold calling superintendandants, Seesaw aims to get a bunch of teachers in a district raving about it. That way administrators know if they pay to equip all their teachers with Seesaw, they’ll actually use it.
