Draft2Digital

Draft2Digital is a strong match for the concept of an online publishing platform. It provides tools for authors to format and publish their books (ebooks and print-on-demand) to various retailers, which aligns with the 'rich-text-editor' and 'distribution-and-recommendation-engine' features. The platform's business model involves taking a percentage of sales, which is a form of 'membership-monetization' for the platform itself, and it offers detailed sales and royalty reports, directly matching 'reader-engagement-metrics'. Additionally, it provides 'Books2Read' tools like author pages and universal book links, which support 'user-profiles-and-following' and 'social-sharing-and-embedding'. While it focuses on books rather than general articles, the core functionalities for content creation, distribution, monetization, and analytics are present.
