Partners can be tricky, particularly if you don't know them. My experience has often been that it's possible to find venture capitalists to push a business forward, but that's what you're saying you don't want. Besides, what they typically want is an already successful startup so that business potential is already apparent. Low risk investment.

Sorry to start out so negative, but from here, what are reasonable alternatives? There are sites where you can offer some kinds of software. You can even sell on amazon. Outside the box innovative solutions? Maybe someone will look at stats and have AI evaluate startups in a way that filters to some set of potentially successful products and be willing to enter such a risky market.
