I don't necessarily agree with this. I used to work at frog design and am now 100% independent (doing consulting/contract work). There are loads of companies from startups like Gowalla and Whaleshark to more established companies like Facebook and BazaarVoice. On top of that, there are some what I would consider "serious" startups with quality founders and funding, like Spacecraft and Mass Relevance.
