There is unfortunately a large gap between "mildly positive" feedback and getting paid. This is not a judgment on the quality of your offering or your ideas but a suggestion as to how far you still have to travel. Paradoxically, negative feedback can be more useful since it gives you an idea of what needs to be changed.
I would find part time or consulting work that allows you to continue to pursue your startup and focus on what businesses are actually willing to pay for. I would also see if you can find someone else to join you as a partner/co-founder.
