Webinar software comparison: WebinarJam vs ON24
WebinarJam vs ON24: key differences
The short answer: WebinarJam is built to sell from single events, while ON24 is built to measure engagement across many events.
Engagement. Both offer polls, Q&A and CTAs. WebinarJam adds live-selling tools such as offer buttons and spotlighting, while ON24 adds personalization and always-on content hubs.
- Reporting and AI: WebinarJam gives basic attendance and conversion reports. ON24 scores engagement, builds attention heatmaps and repurposes content with AI.
- CRM and marketing automation: ON24 syncs engagement data natively with HubSpot, Salesforce and Marketo for lead scoring and nurture. WebinarJam connects to common email tools and uses third-party automation for most CRM sync.
Why it matters: Reporting is the widest gap, and it matters most if you attribute webinars to pipeline. If webinar data has to land in your CRM automatically, ON24 is the better fit. Confirm the connector list with each vendor.
