Should I give up?
skmurphy: 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.
