Riddle

What Riddle does

Riddle Technologies AG is a German SaaS company founded in 2014 and headquartered in Saarbrücken, Germany, that operates an interactive content platform built around 35+ formats including quizzes, personality tests, polls, surveys, forms, score predictors, leaderboards, and mini-games such as crosswords and Sudoku. The platform is delivered as a no-code browser-based authoring tool with embeddable widgets and plugins for WordPress, Webflow, Sitecore, and Drupal, complemented by a public API, Zapier integration covering 9,000+ apps, and a proprietary AI quiz generator that produces questions, answers, and results from a URL or topic in approximately 20 seconds. Riddle holds ISO 27001 certification and is GDPR, CCPA, and WCAG 2.1 compliant, with all data stored in EU regions (Germany and Luxembourg) and a tracker- and cookie-free architecture designed for the post-third-party-cookie environment.

The company monetizes through a tiered subscription SaaS model (Starter, Business, and Enterprise) with a 14-day full-feature free trial, no credit card requirement, a 30-day money-back guarantee, and an Enterprise tier sold on annual contracts with custom pricing, SSO, and dedicated support. Revenue is supplemented by built-in ad monetization (creators retain 100% of ad revenue from their own display and video ads) and sponsored content infrastructure. Go-to-market combines product-led growth (self-serve trial) with enterprise field sales for large publishers, brands, and sports organizations. Customers include BBC, CNN, LinkedIn, Manchester City, Chicago Bulls, Oxfam, Greenpeace, Stage Entertainment, Immediate Media, SRF, Red Bull Media House, Tate Modern, and Fiesta Bowl. The company has expanded its product surface through two acquisitions, qzzr.com in October 2022 and Convert from Contentbird in February 2026, the latter rebranded as Convert by Riddle to serve the DACH market with prediction games and advent calendars.

Direct peers

• ScoreApp: Quiz funnel platform designed for lead scoring and segmentation. Overlaps with Riddle's personality quiz and recommendation engine functionality for marketers.
• Typeform: Barcelona-based interactive form and quiz builder. Directly competes in the same conversational form/quiz category, targeting marketers and publishers with similar self-serve and enterprise motions.
• Interact: Quiz maker focused on lead generation and content marketing. Direct competitor on quiz creation, lead capture, and segmentation, with overlapping ICP in SMB and mid-market.
• Outgrow: Interactive content platform for calculators, quizzes, and assessments. Closely comparable product offering and customer base (marketers, publishers, lead-gen).
• Playbuzz (now Ex.Co): Interactive content platform for publishers serving similar media and brand customers. Direct overlap in quizzes, polls, and listicles for editorial monetisation.
• involve.me: Funnel builder offering quizzes, forms, calculators, and surveys. Named as a direct competitor in Riddle's own comparison pages and operates with similar no-code PLG economics.

Emerging players

• Mentimeter: Live polling and audience interaction tool. Comparable for live and asynchronous engagement formats, though more presentation-oriented than Riddle's content embedding model.

Broad incumbents

• SurveyMonkey: Established survey and feedback platform with quiz capabilities. Competes at the enterprise end of Riddle's market with a wider portfolio but less interactive-content specialisation.
• JotForm: Larger form-builder incumbent offering quiz and survey modules as part of broader form-creation suite. Competes on price and breadth rather than depth of interactive content.
• Qualtrics: Enterprise experience management platform with survey and assessment capabilities. Targets large enterprises that may also evaluate Riddle for engagement use cases.
