I don't think so. Being a 50mm company probably includes no longer serving the majority of markets they do now. At 50mm they become a regional taxi service with phone hailing rides.

Truth is - now that they are public ~ I'm not sure what success is... for a lot of people who started there a long time ago - the IPO was 'the success' now the public is left holding the bag (mostly by their own choice of buying the stock).
