A new kind of the portal model has been financed with fresh VC. Knowledgestorm.com has received USD 2.4 mio in a second round. I'm skeptical about the business model in general. They claim to be cash-flow break-even since last November; I ask myself how the revenues will sustain.

Indeed it's an excellent source of information, if you look for Tech to buy, but what hinders you to google for the mentioned solution and start the shortlisting by yourself and bypassing the portal? How can Knowledge storm lock in customers in future?
