"But I am wondering - are they for real?"
They will really take your money.
If you've exhausted all of your social capital and none of your friends, folks you have prior shared success with (e.g old bosess, co-workers, team members, customers, suppliers), family/relatives, and current advisors (e.g. lawyer, CPA, banker, others) are willing to help you then you can pay these guys to broadcast your business plan or profile.
You might ask them for three references who actually raised money as their testimonials seem to revolve around arranging meetings where founders can touch the hem of a VC's cloak--but no money seems to have changed hands.
Alternatively you might reconsider your business model, as a parent I would be willing to pay pikluk so when I see "The PikLuk Service is FREE and it provides a safe Internet experience for your children." I wonder how you are going to make money in a way that doesn't conflict with your primary brand promise.
