Perhaps, a shift on focus from large institutional partnerships to user acquisition might help with the main goal of this project which you clearly described. I'm suggesting this as simply having an interested community might be on your side when presenting your project to particular VC and it might make your case stronger?
In that way, it doesn't strike me as too carefree not to invest a little in marketing strategies some of which have been mentioned on here already.
In any case, with the info available these are my thoughts but maybe there are other factors at play affecting these decisions that I'm not aware of.
