Riddle vs BillingEngine

Clone & embed royalty-free viral quizzes, lists, and polls

Riddle is the first viral content marketplace - think Getty Images for viral quizzes, lists, and polls.

Interactive content is powerful for engaging and growing audiences but requires time and expertise to create.

With Riddle's marketplace, publishers and brands can quickly grab high-quality interactive content for their audience, written by hand-selected viral experts.

Content is either free to embed 'as is' - with a makeover to match the look and feel of their site, but with no editing the text, images, and author attribution.

Or, they can buy a license from the creator (they set the price - starting at $5) - and change anything and everything about it, to make this version uniquely theirs.

Publishers get viral content - creators get rewarded. Simple and scalable, with built-in lead generation to collect user email addresses and responses to marketing campaigns.
