do we need a pusher/seller/rainmaker?
jdileo: Google, Microsoft, GE, Salesforce.com, etc all have excellent sales and marketing executives who have driven their success and play a key part in relaying customer feedback to the organization.  So, yes, you need the rainmaker if you feel you and your partner do not qualify.
In my mind the technologist & rainmaker comprise the left & right hands of any company.......you need them both and one only suffers if their counterpart is not supremely talented.Questions:What stage is your product?  Enterprise or consumer?  Are you at $0 Gross Sales or $1+ and building?  Are you building TNBT or seek to exit early?  Are you bootstrapped, how do you compensate this individual?
