Last month the first Y Combinator index ranked the entire portfolio by web traffic and Facebook monthly active users (where applicable). These two data points provided some relative ranking, but didn’t do much to bring enterprise companies to their expected positions in the list and overly favored companies with short term spikes in traffic rather than long term investments in building teams, earning inbound links and creating audiences on socia media channels.
This new ranking factors indicators like Facebook likes, Twitter followers, web traffic, page rank, inbound links, number of employees and other data I am collecting through proprietary methods.
You’ll now see companies like Clustrix (scale-out SQL databases) and Cloudant (distributed database as a service) in the top ten, along with big jumps from OwnLocal (publisher tools & monetization), MemSQL (another database company!), AeroFS (private file syncing and collaboration) and many more. The Winter 2013 companies have also been added.
