Finally I got time to catch up on all the blog posts. I saw this interesting post from Phil Wainewright on SaaS Capital :
SaaS enables the new pay-as-yo-go business model. But this is not always a great news for software vendors. It takes the new software projects a longer time to break-even and puts higher cash requirements on folks raising capital.
There is this new VC company called http://www.saas-capital.com/ that give debt financing to companys based on their on-demand software contracts. Great Idea.
