Padlet

Founder Nitesh Goel has a bold vision: to become “the easiest way to put stuff on the Web.” Padlet's elegance lies in its simplicity: drag and drop anything from your desktop or the Web onto a blank canvas--text, video, images. Resources can  be shared across a multitude of social networks and accessed at custom url via web browser.

Teachers, students--anyone, really--can contribute and collaborate on the same space. Shortly after launch, Goel claimed to have over 300K monthly active users across 197 countries, who had created over 1 million padlets for education. “When something that is so simple has so much growth, it means it is solving a fundamental problem.” Padlet has premium features for $50 a year, which will include vanity URLs, larger file uploads, and privacy controls.

Padlet, fomerly called Wallwisher, was part of the Imagine K12 fourth cohort in 2013.
