ON24 and Zoom Webinars both power large-scale virtual events, but they serve different organizational needs and maturity levels. Zoom Webinars is the accessible, familiar option — an add-on to Zoom's existing video infrastructure with straightforward pricing, Q&A, polls, and support for up to 50,000 attendees. ON24 is the enterprise webinar intelligence platform, built around content performance analytics, buyer journey integration, and CRM data enrichment — used heavily by B2B demand generation teams.

The practical difference is sophistication and price: Zoom Webinars starts at $83.33/month and is operational within minutes. ON24 requires enterprise contracts and professional services to implement, but delivers the engagement data and integrations that B2B marketing teams need to justify webinar ROI to sales.

Our Verdict

For most organizations hosting webinars as a marketing channel, Zoom Webinars is the pragmatic choice — affordable, familiar, and operational with minimal setup. The $79/month starting price is accessible to any marketing team, and attendees need no onboarding since they likely already have Zoom installed.

ON24 is justified when webinar ROI must be measurable in CRM terms: when marketing is accountable for pipeline influenced by webinars, when engagement scores drive follow-up sequences, and when the webinar content asset library needs to function as an always-on demand generation engine. This level of sophistication requires enterprise budget (typically $25K+ annually) and professional services for implementation. If you're not sure you need ON24's analytics depth, Zoom Webinars with manual CRM follow-up will cover 80% of organizations' needs at a fraction of the cost.

Frequently Asked Questions

01 How much does Zoom Webinars cost?

Zoom Webinars is an add-on to an existing Zoom Pro plan ($13.33/month). The Webinars add-on starts at $79/month for up to 500 attendees and scales up to $340/month for 3,000 attendees. Large capacity plans for 5,000–50,000 attendees require custom quotes.

02 Is ON24 worth the cost for small teams?

Generally no. ON24's enterprise contracts ($25K–$60K+/year) are designed for mature B2B marketing teams with dedicated event marketing resources and CRM infrastructure. Small teams get better ROI from Zoom Webinars or Demio at a fraction of the cost.

03 Can ON24 integrate with Salesforce?

Yes. ON24's native Salesforce integration syncs attendee engagement data, content interactions, and webinar scores directly into Salesforce contacts and leads — a key differentiator over Zoom Webinars, which requires manual export or third-party integration for CRM sync.

04 What's better than ON24 for mid-market?

For mid-market B2B companies that want more analytics than Zoom but can't justify ON24's pricing, alternatives include Demio, BigMarker, and Goldcast. These typically run $300–$800/month and offer CRM integrations without enterprise-level implementation complexity.
