ClassConnect brings the GitHub model to K-12 lessons. By crowdsourcing lessons, it saves teachers a TON of time and you end up with higher quality content being used in the classroom. I went through the Imagine K12 incubator program and I just launched ClassConnect (!). I've signed up over 3K teachers since launching a week and a half ago, so things are going pretty well. I need to find some cofounders that are as passionate as I am about enhancing education!!
