You'll have to find some early adopters who are willing to take a risk in order to solve a critical business problem. Once you have those few reference customers, additional sales become much easier and you can afford to hire more employees.

In the short term try offering to put the source code in escrow so that if your company fails the customers can take over the product themselves. This reduces their risk a little, at least for large enterprises with competent IT departments.
