Link: Virtual Nerd: Real math help for school and home

While pursuing his MD/PhD and working as a math and science tutor, Leo Shmuylovich loved being able to help students master topics which had previously caused them confusion and frustration. But he found himself unable to keep up with demand for his assistance—he simply did not have enough time to work with all the students who needed his help.

Leo thought he might be able to help more students if he recorded video explanations of common trouble topics and shared them online.

In the Spring of 2008, Leo shared this idea with his friend Josh Salcman, a designer and design strategist. They quickly realized they had an opportunity to break new ground, and Virtual Nerd was born.
