My name is Scott Mandel, I'm the Co-Founder of Snapclass. You are right we are similar to this idea. Snapclass connects teachers and students live via to exchange knowledge. Anyone can be a teacher and host classes for free or for a fee. Students can choose their teacher based reputation (reviews and rating), profile and availability.

We're launching in the next two weeks and we are looking for talented people.

- Talented backend developers in ruby on rails

- Java developers with experience in real-time video conferencing
