Side-by-side comparison of AI visibility scores, market position, and capabilities
B2B digital event platform with $160M revenue; webinar engagement data (poll responses, downloads, time watched) as first-party pipeline intelligence feeding Salesforce and Marketo.
About
ON24 is a digital experience platform for B2B marketing, enabling companies to run webinars, virtual conferences, and on-demand content experiences that capture audience engagement data and convert viewers into qualified sales pipeline. Founded in 1998 and headquartered in San Francisco, ON24 is listed on NYSE (NYSE: ONTF) and generates approximately $160 million in annual revenue serving enterprise marketing teams at companies including Microsoft, SAP, and Merck who use digital events as a primary demand generation channel.\n\nON24's platform goes beyond basic webinar hosting — every attendee interaction (poll responses, Q&A questions, resource downloads, content watched, time spent) is captured as first-party engagement data that flows into CRM and marketing automation systems (Salesforce, Marketo, HubSpot) as behavioral intent signals. This transforms webinars from one-way broadcasts into data-generating demand generation assets. ON24 Intelligence analyzes this engagement data to score prospects by their buying signal strength based on their webinar behavior patterns.\n\nIn 2025, ON24 operates in the digital events and webinar platform market that exploded during COVID-19 and has since contracted as in-person events returned. The company has repositioned from "webinar platform" to "digital experience platform" emphasizing the first-party data and pipeline generation value rather than the meeting technology. ON24 competes with Zoom Webinars, Hopin (now RingCentral Events), Cvent, and video marketing platforms for B2B event and content marketing budgets. The 2025 strategy focuses on ON24 AI-powered personalized content experiences (where each viewer sees customized content based on their profile), growing its Content Hub (always-on content experience) product, and helping marketers demonstrate revenue attribution from digital events.
