You're pointing to an information problem that has little to do with non-excludability. A prospective funder faces the exact same issue anyway! And crowdfunding has been used to fund many sorts of good/service provision where non-rivalry is an issue. It does appear to work quite a bit better than other market-based options.
More generally, non-excludable goods do not work well within a free market system. If you want them produced, you either set up a state mechanism for funding them (which many countries do for e.g. film, by creating national film funds), or you somehow make them excludable (e.g. through copyright). The other options aren't really effective.
