Vellum

book-formatting software

Vellum

Industry Publishing

Mac software used by independent authors and publishers to format ebooks and print books. Vellum scores well because it sells production capability directly without taking rights, royalties, or reader relationships.

Why this matters: Vellum is a good narrow author tool: it sells useful software without taking rights or platform control, though it is proprietary and Mac-only.
