I think you already know the answer, but here it is: when running a SaaS, you should be either closing deals or shipping code that is being paid by these deals, especially in the early days...
Please note that you have to get an actual deal (i.e. contract/payment) before you start coding. I've fallen way too much in the trap where I didn't get a written commitment to "if you have this I will buy". This has never worked for me.
