This post is part of our ongoing coverage of Y Combinator Demo Day Summer 2013. If you like what you read here we hope you will consider subscribing to Mattermark Weekly – our weekly newsletter on startups investing.
We’ve ranked the current Y Combinator Summer 2013 batch by Mattermark Score – which awards points to each company on a weekly basis for increasing their website traffic, mobile downloads, inbound links, Twitter followers, Facebook likes, and LinkedIn followers. Weekly scores are averaged over 90 days to arrive at the Mattermark score, to help account for spikes and drops related to PR (which can have a huge impact on growth rates in the early days of a company).
