By listening to its core audience--teachers--ClassDojo's educational software has reached 90% of U.S. schools. Now the real work begins: how to get someone to pay for it.

ClassDojo has developed digital tools that can help teachers, parents, and students improve classroom behavior, develop good learning habits, and support character development.

New ClassDojo features are intended to give educators, parents, and students a safe way to share and build school community.

ClassDojo, a startup that has built a platform for teachers and parents to communicate small and big updates to each other, today is announcing that it has raised $35 million in funding.
