Goldcast vs. ON24 (vs. ZoomInfo): 2026 Comparison

If you're comparing Goldcast vs. ON24 for your B2B webinar and virtual event programs, know this first: both platforms are now owned by the same company. Cvent acquired Goldcast in December 2025 and closed its ON24 acquisition on April 1, 2026. That changes the comparison in ways most articles won't mention.

But the platforms remain distinct products today, and each serves a different kind of B2B marketing team. The real questions are:

• Are you running a high-volume webinar program that needs analytics and compliance controls, or a video content operation that needs to turn every event into clips and social posts?

• Do you need engagement data from your events to flow into sales workflows with full buyer context, or is a basic CRM sync enough?

• Is your team large enough to absorb a steep learning curve, or do you need to move fast with a leaner setup?

• How important is it that the people watching your webinars become leads with verified contact data, not just names on a registration list?

• Are you choosing a webinar tool, or building a demand generation engine?

Here's what we recommend:

Goldcast fits mid-market B2B marketing teams that treat webinars as a content engine, not just a lead capture event. Its AI-powered Content Lab turns a single webinar into clips, blog posts, social posts, and email copy within minutes of the event ending. If your primary goal is to get more content out of every event, Goldcast delivers. However, its pricing requires a demo, its Content Lab can't splice non-chronological clips together, and smaller teams may find the platform's breadth overwhelming.

ON24 is the enterprise standard for organizations running large-scale, compliance-sensitive webinar programs where first-party engagement data matters more than content repurposing. ON24 captures behavioral signals from every attendee interaction and routes them to CRM and marketing automation systems. If your webinar program is a core pipeline channel and you need analytics with compliance controls, ON24 is proven. The downsides: steep learning curve, premium pricing that excludes mid-market buyers, and a mobile experience that lags behind newer competitors.

Both platforms capture engagement data from your webinars. But engagement data alone doesn't close deals. Sales teams need to know who attended, what their role is, whether their company is actively in-market, and how to reach them directly. That's the gap between running a webinar and generating pipeline from it.

ZoomInfo is a GTM platform that turns engagement signals from your webinar platform into a pipeline. Built on a B2B data foundation of 500M contacts, 100M companies, 135M+ verified phone numbers, and 300M+ verified business emails, ZoomInfo's GTM Context Graph (processing 1.5B+ data points daily) combines your CRM records, conversation transcripts, and behavioral signals with third-party intelligence to show which accounts are ready to buy and why. Your webinar tells you someone attended. ZoomInfo tells your sales team who that person reports to, what technology their company runs, whether they're researching competitors, and how to reach the decision-maker. That intelligence flows through GTM Workspace for sellers, GTM Studio for marketers and RevOps, or APIs and MCP into any tool in your stack.

If turning webinar engagement into closed revenue is the actual goal, see how ZoomInfo connects your event data to the intelligence that moves deals forward.

Goldcast vs. ON24 vs. ZoomInfo at a glance

The Cvent factor: Both platforms, one owner

Before comparing features, it's worth understanding what the Cvent acquisitions mean for buyers evaluating these tools today.

Cvent acquired Goldcast for a reported ~$300M in December 2025, positioning Goldcast's AI video repurposing as a complement to Cvent's enterprise event management infrastructure. Four months later, Cvent closed its ON24 acquisition, adding ON24's engagement data and AI content engine to the same portfolio.

Cvent now owns three event platforms: its own in-person event management system, Goldcast for AI-powered video content, and ON24 for enterprise webinar engagement. The stated strategy is to build a unified "event-led growth" platform spanning physical, virtual, and hybrid events.

For buyers, this creates opportunity and uncertainty. The opportunity: deeper product integration could eventually deliver a single platform covering the full event lifecycle. The uncertainty: no public integration timeline exists, product roadmaps may shift to serve Cvent's consolidated vision rather than each platform's independent direction, and there's real risk of feature overlap leading to one product being absorbed into the other.

If you're signing a multi-year contract with either Goldcast or ON24 today, you're betting on Cvent's integration strategy.

Goldcast wins on content repurposing, ON24 wins on engagement analytics

Each platform was built to solve a different post-event problem.

Goldcast treats every webinar as raw material for content. When an event ends, Content Lab generates video clips, blog drafts, social posts, email copy, and key takeaways. Users can highlight any passage in the transcript and create a clip without touching a video timeline. The Agentic Video Editor handles jump cuts, captions, scene transitions, and branded overlays with little human input.

ON24 treats every webinar as a data source. Its ACE engine captures engagement signals from every poll response, Q&A submission, resource download, and CTA click, then routes that data to CRM and marketing automation platforms. The Prospect Engagement Profile embeds in Salesforce, showing sales reps a prospect's full content journey, AI-generated business interests, and recommended next-best content.

Source: ON24

The distinction matters because it reflects what each platform optimizes for. Goldcast optimizes for reach: how many pieces of content can one event generate? ON24 optimizes for conversion: how much buyer intelligence can one event capture?

The webinar experience differs in production philosophy

Goldcast and ON24 take different approaches to what a webinar looks and feels like for attendees and producers.

Goldcast emphasizes production quality. Features like overlays, lower thirds, tickers, session autoplay, and captions give even a standard webinar a broadcast feel. The Enhanced Stage Controls separate a private backstage (with video feeds, private chat, and speaker status tracking) from the live stage. Speakers enter via a unique magic link, complete a built-in tech check, and wait backstage until the producer brings them on. It's designed to make every webinar feel like a produced show.

ON24 emphasizes operational control and data capture. Elite Studio supports up to 10 simultaneous producers and presenters (expandable to 20) plus unlimited Q&A moderators. The role separation between Producer, Presenter, and Q&A Moderator gives enterprise teams control over who does what during a live event. ON24's standout capability is Simu-live and Sim-2-Live: pre-recorded webinars that play at scheduled times with live engagement tools active. Teams record a webinar once, then run it as a "live" event multiple times without requiring presenters. This is particularly useful for global programs running the same content across time zones.

Source: ON24

Both approaches work. Goldcast's suits teams that want polished, media-quality events with fewer production staff. ON24's suits high-volume programs where operational efficiency and reusability matter more than production polish.

AI content capabilities: Two different engines

Both platforms offer AI-powered content generation, but they work differently.

Goldcast's Content Lab processes videos immediately upon upload, generating clips, social posts, blog drafts, email copy, and takeaways. Users customize output by adjusting tone (professional, conversational, playful), length, and channel-specific prompts. Social posts can be generated in 17 languages. The Agentic Content Curator (in beta) surfaces relevant clips from the video library based on brand story fit. For Goldcast customers, event recordings flow into Content Lab without an export step.

Source: Goldcast

ON24's ACE uses Microsoft Azure OpenAI's technology to generate blog posts, eBooks, key takeaways, transcripts, FAQs, social posts, and follow-up emails from event recordings. What sets ACE apart is Key Moments: rather than just processing the transcript, ACE analyzes live audience behavior (questions, poll responses, emoji reactions) to identify peak-engagement moments, then generates video clips from those timestamps. The output reflects what actually resonated with attendees, not just what the speaker emphasized. ACE also includes AI Brand Voice, which applies brand guidelines to all generated content.

Source: ON24

Goldcast's content engine is faster and more hands-on, letting marketers iterate on clips and posts immediately. ON24's is more analytically driven, using engagement signals to determine which content to create. Both produce useful output. The choice depends on whether your team values speed and creative control (Goldcast) or data-informed content selection (ON24).

A limitation both share: neither tells you much about who your attendees actually are beyond what they typed into a registration form.

Where webinar data stops and buyer intelligence begins

Goldcast captures 16+ engagement data points per attendee and syncs them to connected CRM and MAP platforms. It also captures more granular signals through its 21 engagement activity types. ON24 builds Prospect Engagement Profiles with lifetime engagement tracking, AI-generated business interest keywords, and next-best-content recommendations. Both push this data to Salesforce, HubSpot, Marketo, Eloqua, and Pardot.

But webinar engagement data has a ceiling. It tells you that jane@company.com attended your webinar, answered three polls, downloaded a resource, and scored 8/10 on engagement. It doesn't tell you whether Jane is a decision-maker or an individual contributor, whether her company is evaluating solutions like yours, who else on the buying committee should be involved, or how to reach the CFO who signs the contract.

This is the gap ZoomInfo fills.

ZoomInfo's GTM Context Graph (processing 1.5B+ data points daily) combines your CRM records and engagement data with ZoomInfo's third-party intelligence: 500M contacts with verified phone numbers and emails, company attributes, org charts, technographics, and buyer intent signals from 210 million IP-to-Organization pairings. When a webinar attendee's engagement data lands in your CRM, ZoomInfo enriches it with the attendee's role and seniority, their company's tech stack, whether the company is showing intent signals for your category, and verified direct dials for the entire buying committee.

The difference is between knowing someone attended your webinar and knowing why they attended, who else at the company is researching your space, and how your sales team should follow up.

Seismic attributed 39% of active pipeline to opportunities identified or influenced by ZoomInfo signals, with sales teams saving 11.5 hours per week and boosting productivity by 54%.

Integration depth shapes what you can do with event data

All three platforms integrate with major CRM and MAP systems, but the depth and direction of those integrations differ.

Goldcast offers native two-way integrations with Salesforce, HubSpot, Marketo, Eloqua, and Pardot, plus Slack for real-time sales alerts. Webhooks are available on Pro plan and above. Goldcast's integration strength is speed-to-lead: engagement data syncs to CRM within 5 minutes of an event, with engagement scores following within 30 minutes. The limitation is breadth: teams using tools like 6sense, Demandbase, Outreach, or Salesloft need webhook workarounds or Salesforce intermediaries.

ON24 has the widest integration roster among webinar platforms, with native connectors for Salesforce, HubSpot, Marketo, Eloqua, Microsoft Dynamics, SugarCRM, Veeva, and 30+ other platforms. The LinkedIn integration lets customers publish ON24-hosted experiences to LinkedIn Events and connect engagement data to LinkedIn ad campaign performance. ON24 also exposes a REST API for custom builds. For enterprise buyers with complex tech stacks, ON24's integration coverage is a real advantage.

ZoomInfo approaches integration from the other direction. Rather than pushing event data out, ZoomInfo pulls intelligence in from everywhere and makes it available through 120+ marketplace integrations, Enterprise APIs, and MCP access that connects ZoomInfo's data to any AI agent or custom application. API access is included in all plans. In practice: when Goldcast or ON24 pushes webinar engagement data into Salesforce, ZoomInfo enriches those records with verified contact details, company intelligence, and intent signals, then surfaces the complete picture in GTM Workspace for sellers or GTM Studio for marketers.

Spekit found that accounts with higher ZoomInfo scores were 43% more likely to turn into qualified pipeline and moved 58% faster through qualification.

Pricing: None of them make it easy

All three platforms use custom-quoted pricing, which makes direct cost comparison difficult. Here's what's publicly known.

Goldcast structures pricing across four plans: Starter, Pro, Premium, and Enterprise. No dollar amounts are published. Starter includes 12 webinars per year, 3 users, and basic integrations. Pro adds 25 events, cross-event analytics, and ROI dashboards. Premium opens multi-day events and more integrations. Enterprise adds unlimited events and custom reporting. The Content Lab module has a free plan with 1 hour of uploaded video per month, limited to a single user with Goldcast branding on all clips. Additional costs include SSO (add-on on Pro/Premium), whitelabel (add-on at every plan), field events (add-on), and extra users beyond the base allotment.

ON24 names three plans: Essentials, Standard, and Advanced. No prices are published. The critical gating: AI-powered ACE features (content generation, Key Moments, advanced analytics) require Standard or above. Content hubs and personalized landing pages require Advanced. Virtual events are an add-on at every tier. ON24 is consistently described as among the most expensive webinar platforms, with licensing that scales steeply with event size and seat count.

ZoomInfo offers something neither webinar platform does: a permanent free plan. ZoomInfo Lite provides access to ZoomInfo's B2B database with 10 monthly export credits, website visitor reveals, and HubSpot integration at no cost, with no time limit. A 7-day free trial of the full platform is also available. Paid plans are organized into Sales plans (Professional, Advanced, Enterprise) and Marketing plans (Marketing Demand, ABM Lite, ABM Enterprise), all custom-quoted based on seats, credits, and features.

The pricing reality for most B2B marketing teams: you'll likely need both a webinar platform and a data platform to run an effective demand generation program. The question isn't which single tool to buy, but which combination delivers the best return.

Support and onboarding reflect platform complexity

Goldcast commits to onboarding new customers and running a test event in under 30 days. Support is available via email and live chat from 9 PM ET Sunday through 9 PM ET Friday, with chat and email support activating 30 minutes before any live event. Published metrics: 96% support CSAT, 55-second first response time for live events, and 24-minute median time to resolution.

ON24 provides live chat and ticket submission, plus phone support (reserved for live event emergencies). Professional services come in tiers: Event Monitoring (2.5 hours), Event Management (6 hours), and Town Hall Services (12 hours) for individual events, all purchased separately. ON24 also offers launch packages scoped to 90 days of activation per module. The learning curve is real: ON24's services page acknowledges that organizations "often lack the in-house resources to plan, execute, and manage webinar programs on the platform independently."

ZoomInfo redesigned its onboarding program from 30 to 90 days, producing a 25% improvement in customer satisfaction scores. ZoomInfo University provides role-specific learning paths, certifications, and live webinars. Direct support is available via the Help Center, phone, and professional services through ZoomInfo Labs.

Security and compliance: Enterprise requirements

All three platforms maintain enterprise security certifications, but the specifics differ.

Goldcast holds SOC 2 certification with AES-256 encryption at rest, SSL/TLS in transit, quarterly external penetration tests, and a 99.99% uptime target. An EU data residency option is available for webhook data.

ON24 maintains ISO 27001, ISO 27701, SOC 2 Type II, and APEC PRP certifications. It operates separate NA and EU data centers with independent status monitoring, supports GDPR compliance through a Data Processing Addendum, and maintains a CCPA compliance program. For regulated industries (life sciences, financial services), ON24's compliance posture is notably deeper than Goldcast's.

ZoomInfo carries the broadest certification stack: ISO 27001, ISO 27701, SOC 2 Type II, TRUSTe GDPR and CCPA validations, all renewed annually. ZoomInfo is a registered data broker in California and Vermont, reflecting the regulatory requirements of operating the world's largest B2B contact database.

Goldcast vs. ON24 vs. ZoomInfo: Which should you choose?

These three platforms solve different problems in the same workflow. Your choice depends on which problem is most urgent.

Choose Goldcast if:

• You want to turn every webinar into a week's worth of multi-channel content

• Your team is lean and needs AI to handle post-event production

• You run 10-50+ webinars per quarter and need to get more content from each

• You value production quality and branded attendee experiences

• You're comfortable with the uncertainty of Cvent's integration roadmap

Choose ON24 if:

• You run a high-volume enterprise webinar program where engagement data drives pipeline

• Compliance controls matter (life sciences, financial services, insurance)

• You need Simu-live capability to scale content across time zones without live presenters

• Per-attendee engagement profiles are central to your sales motion

• Your organization has the resources to absorb a steep learning curve and premium pricing

Choose ZoomInfo if:

• You need to connect webinar engagement data to verified buyer intelligence

• Your sales team needs more than a lead list: they need org charts, direct dials, intent signals, and buying committee context

• You want one intelligence layer that enriches every tool in your stack, not just your webinar platform

• You're building a demand generation engine where events are one channel among many

• You need your data accessible everywhere: in your CRM, in AI agents, or through APIs

See how ZoomInfo turns event engagement into pipeline intelligence.

The strongest B2B demand generation programs don't choose between a webinar platform and a data platform. They use both. Goldcast or ON24 captures the engagement. ZoomInfo provides the intelligence that makes it actionable. One generates the signal. The other provides the context to act on it. Together, they turn a webinar from a marketing activity into a revenue event.

Goldcast vs. ON24 vs. ZoomInfo FAQ

What is the main difference between Goldcast and ON24?

Goldcast is a video content platform that turns webinars into multi-channel content (clips, blogs, social posts, emails) through its Content Lab and Agentic Video Editor. ON24 is an enterprise engagement platform that captures first-party behavioral data from webinar attendees and routes it into CRM and marketing automation systems for pipeline attribution. Both are now owned by Cvent.

Are Goldcast and ON24 merging under Cvent?

Both were acquired by Cvent (Goldcast in December 2025, ON24 in April 2026) and now operate under the same parent company. No public integration timeline has been disclosed. Both remain available as separate products today, but buyers should consider how Cvent's consolidation strategy may affect product roadmaps and long-term support.

How does ZoomInfo relate to Goldcast and ON24?

ZoomInfo is not a webinar platform. It is a complementary intelligence layer that enriches the engagement data captured by Goldcast or ON24 with verified contact information, company attributes, org charts, technographics, and buyer intent signals. When a webinar attendee's data reaches your CRM, ZoomInfo adds the buyer context that helps sales teams prioritize and personalize follow-up.

Which platform is best for a mid-market B2B company?

Goldcast is typically the better fit for mid-market teams, with faster onboarding, less operational complexity, and a focus on content multiplication that benefits leaner teams. ON24's pricing and learning curve are oriented toward enterprise organizations with dedicated event operations staff. ZoomInfo serves both segments through tiered pricing, with a permanent free plan (ZoomInfo Lite) and a 7-day trial available.

Which platform captures the most useful data from webinars?

ON24 captures the deepest engagement data, with 20+ interaction types per attendee, lifetime engagement tracking via Prospect Engagement Profiles, and AI-generated business interest keywords. Goldcast captures 16+ behavioral data points per attendee. However, neither platform provides verified contact data, company intelligence, or buyer intent signals beyond what registrants self-report. ZoomInfo fills that gap by enriching webinar leads with third-party verified data.

Do any of these platforms offer a free plan?

Goldcast offers a free Content Lab plan limited to 1 hour of video uploads per month with a single user and Goldcast branding on clips. ON24 does not offer a free trial or free plan. ZoomInfo offers ZoomInfo Lite, a permanent free plan with access to the B2B database, 10 monthly export credits, and website visitor identification, plus a separate 7-day free trial of the full platform.

Which platform has stronger AI capabilities?

All three invest in AI, but in different areas. Goldcast's AI focuses on video production (agentic editing, content curation, brand-aware clip generation). ON24's ACE uses engagement signals to identify peak moments and generate content that reflects actual audience behavior. ZoomInfo's GTM Context Graph uses AI to reason across CRM data, conversation intelligence, and third-party signals to surface why deals move and which accounts to prioritize. The AI capabilities are complementary rather than competitive.

Can I use Goldcast or ON24 together with ZoomInfo?

Yes. Both Goldcast and ON24 integrate with CRM and MAP platforms where ZoomInfo data already lives. When webinar engagement data from either platform reaches your CRM, ZoomInfo's enrichment layer automatically enhances those records. ZoomInfo's buyer intent data can also inform which accounts to invite to webinars, and ZoomInfo's GTM Studio can orchestrate post-event follow-up plays using engagement signals from either platform.
