Sales and Limited Time at my Startup, [I will not promote]

I am builiding a SAAS for therapists in private practice. I am the technical co-founder and need pretty much all my time for building. My co-founder is the CEO and she is spending much of her time with fundraising. This leaves us with less time than we need for sales, especially to do it correctly. We have looked at 2 options, bring another sales person on as another founder, or hire an EA for the CEO that will do a lot of SDR work. I am curious what you all think of these options and how you may have solved this problem in similar situations. \[I will not promote\]
