A new startup app that allows parents and teachers to interact has gone viral

If you are the sorts of parents who like to keep a close tab on your kids, especially when they are away at school, this one is definitely for you. ClassDojo is an app, available on the Apple Store and Google Play, which is a shared classroom platform where teachers can upload videos and pictures of schoolwork for the benefit of parents, and also discuss the progress of a child. Think of it as a social media platform for parents and teachers.

Founded by Welsh-born Sam Chaudhary and Liam Don, the app has garnered millions of users worldwide, especially in the teaching community, according to Lindsay McKinley, head of communications at ClassDojo. The app creates a shared classroom experience between parents, teachers, and students. Teachers upload photos, videos, and classwork to their private classroom groups which parents can view and "like." They can also privately message teachers and monitor how their children are doing in their classrooms through the behavior tracking aspect of the app. In the behavior tracking portion of the app, teachers give or take away points based on performance or conduct.

Essentially, what ClassDojo does is to foster an atmosphere of collaboration and support, removing the invisible barrier that often exists between the home and classroom. Now, parents need not wait for their once-a-quarter parent-teacher conferences but can have daily dialogues about their children.

The platform is used in two-thirds of all schools—public, private, and charter—across the US and in 90 percent of school districts. It is also used in 180 countries globally, according to McKinley. In fact, more than 500,000 people download the app every day.

In late 2015, the company raised $21 million in a Series B round of venture funding. It had previously raised $8.5 million during its first institutional funding in 2013, and $1.6 million in seed funding in 2012.
