If investors are struggling to see the value of your product, it's because you haven't developed enough of a
commercial pitch.
The technical aspects that matter (unlike other solutions to developing for multiple platforms, ours lets iOS developers write native iOS apps the way they normally would; our solution takes their code and makes it work on Android, the web and other tablets) really shouldn't be difficult to grasp anyone that's remotely serious about tech investment. They need to establish your product has a market and that you're capable of marking it work; technical benefits matter but implementation details are secondary.
They do need to know who will buy your product, why, what evidence of success of similar solutions exists and why yours will be better. They need to know you've implemented large parts already for paid client work, and the clients were impressed because none of the other dev shops they talked to could clone iPhone apps for Android that quickly or cheaply. They want to know you have an idea how you're actually going to sell this, and at what price to what sized market.
If that interests them, that's when you can have all the nice conversations about your innovative ways of using APIs and why this manual aspect of your current process can be automated; you might even find they've got a friendly techie to do that as part of the due diligence.
