Nebula

Artists need money before release and get paid long after it, while the fans who would happily fund them have no way in. Nebula gives fans direct ownership access ahead of release, so the people who care earliest are the ones who benefit.

Music has a timing problem. The cost of making a record lands before release and the income arrives in trickles for years afterwards, which is why advances exist and why they are expensive.

Nebula's version of the fix is ownership rather than crowdfunding: the fan gets something that holds value rather than a thank-you, and the artist gets capital at the moment it is useful. A year-long closed beta with fifty artists is the right way to find out whether that holds.
