I went through the first class of IK12 back in 2011 with ClassDojo. My cofounder and I arrived in California with no connections at all, and only the beginnings of an idea.<p>Tim, Geoff, Karen and the whole IK12 family have been a huge source of support over the past 5 years, helping us scale to the point where ClassDojo is used daily in &gt;50% of US schools.<p>From the beginning they&#x27;ve been driven by the idea of creating large-scale improvements to our education system, and right from the start they committed to that goal for the long term. I&#x27;m delighted by this news, because YC&#x27;s network and resources will only accelerate progress towards that goal.
