Phone-based sales for a SaaS app?

Hey all,
I'm looking for advice on sales for my B2B SaaS application, knowsi.com

I'm pretty focused on UX designers and user researchers as my market, and have been trying to advertise via newsletters for UX designers and my existing communities (I'm an IDEO and US Digital Service alum).

However, while I've gotten one business customer and a fair number of interested (50 in my pre launch signup), I've been struggling to build awareness. Partially, I don't really know much about marketing and sales for SaaS, as my background is design consulting. I'm fumbling along a bit.

I'd love to get advice and ideas on how to sell Knowsi, and whether I should consider cold calling/emailing studios to drive sales? And if so, how should I plan and organize that? And as an indie, how have you managed the sales vs dev (vs content vs etc) balance? What questions am I not asking?
