Unbound
UK-based site applies the principle of "crowdfunding" to book publishing. Agent-recommended authors pitch their book ideas on the site. If you like their idea, you can pledge to support it. If they hit the target number of supporters, the author can go ahead and start writing. If the target isn't met, you can either get your pledge refunded in full or switch your pledge to another Unbound project. Pledging readers get backstage access to the creative process, including updates on the book’s progress, exclusive interviews, draft chapters, information about the author's backlist, and discussions with the author and other supporters.
