Is this service designed to be used from the very first, or only once the product has been rolling for a bit? Any experience with this?
Also was hoping for a profit based pricing model but can't complain there.
To answer the question: we'll certainly be able to help you from day one, but it's a good idea to do some basic market research first -- you'll be spending money on paid user acquisition before you're confident that people will actually buy what you're offering. However, we can definitely help you experiment with researching new segments and types of customers, and it compares favorably against other kinds of acquisition channels in an early stage (Adwords, for example!)
Where LeadGeni.us really shines is when you have a core group of users and you're ready to kick it up a notch and scale things out users -- we can get you conversations, but if your product is still nascent and changing, these may not be the users you want to talk with.
