Do you mind explaining this?

This is what I understood it to mean: a startup grows marketshare rapidly with VC money infusion in an easy money environment. But when credit dries up like it did in 2008, the startup could be left hanging as VCs might not fund the next round of their previously star startups as they want to deploy resources to their absolutely top-rung startups. So, even good startups can be left stranded.

That's the feeling I have. Would like to know if my thinking is on the right track.
