I agree completely with ghshepard. Presuming it's not some sort of consumer play, if one of the founders is not good at sales, you'd sure as hell better (1) learn to sell and/or (2) bring in sales talent. Preferably #1 before #2. The absolute worst mistake you can make is focusing on a fancy technology without bringing in dollars.
Look at the way a typical company runs. They spend huge sums of money on third-rate products, many of which have a superior alternative available. Why didn't they buy the better product? Why do vendors with clearly inferior products get the sales dollars that a vendor with a better product doesn't? It's because the vendor with a good sales team gets the product to the customer, and the fact is that a mind-blowing offering will not get bought unless there's some guy getting that customer to buy that product. If you can combine a fantastic product with a great sales team, watch out. But if you've got a great product but aren't selling early, don't look for a technical solution out of a business problem.
