Pronoun, a self-publishing service for authors, is shutting down after promising free ebook distribution for authors. The company, which raised millions in funding and ended up being sold to Macmillan announced the shutdown in an email to authors and on its website.

We are proud of the product we built, but even more so, we’re grateful for the community of authors that made it grow. Your feedback shaped Pronoun’s development, and together we changed the way authors connect with readers.
