Your marketing team ran 14 virtual events last quarter using three different tools. Each had its own registration page, its own email workflow, its own analytics dashboard. The quarterly review meeting turned into a debate about which numbers to trust. Nobody could answer the simplest question: which program drove the most pipeline.
A truly capable virtual event platform should handle registration, branded landing pages, in-session production, attendee engagement, speaker coordination, and CRM sync that connects it all to revenue. When those functions are spread across separate tools, the data fragments. Attribution gaps widen. And every new event requires rebuilding integrations that should have carried over from the last one.
Platforms built for large-scale attendee experiences consolidate production, engagement, and data into a single system. Below, we evaluate 10 options across those capabilities, with emphasis on where they differ for B2B teams running recurring programs.
Quick comparison: Best virtual event platforms for large-scale attendee experiences
The 10 best virtual event platforms for large-scale attendee experiences
Zuddl
Zuddl is a unified event and webinar platform built for B2B marketing teams managing conferences, field events, and virtual programs from a single system. Its core strength in the virtual event category is combining broadcast-quality production with real-time, bi-directional CRM integration.
What it does well
• The built-in production studio supports pre-defined scene flows, branded overlays, lower thirds, and live speaker transitions without requiring external production tools or app downloads for organizers or attendees.
• Bi-directional integration with Salesforce, HubSpot, and Marketo syncs registration statuses, engagement data, and attendee behavior to CRM in real time, with field mapping for statuses like invited, registered, attended, and no-show.
• Embeddable, SDK-based registration widgets preserve UTM tracking and GA4 attribution, keeping attendee journeys on your owned web properties instead of redirecting to third-party landing pages.
• An AI-powered content hub auto-generates highlight reels, social clips, and blog drafts from session recordings within an hour of event completion, without manual editing.
• One-click event cloning duplicates entire virtual event setups, including integrations, branded assets, registration forms, and communication workflows, reducing repeated setup time for recurring programs.
Where it has gaps
• The breadth of configuration options creates a learning curve for first-time users, though all plans include 30-day onboarding and first-event support to accelerate setup.
Pricing: From $10,000/year
Best for: B2B marketing teams running multi-format event programs (virtual, hybrid, in-person) that need production control, real-time CRM sync, and consolidated analytics across all event types without stitching together separate tools.

Goldcast
Goldcast is a virtual event platform built for B2B demand generation teams. Its primary strength is pairing branded production quality with granular attendee engagement data that flows into CRM and marketing automation platforms.
What it does well
• Branded virtual stages, live video Q&A, and interactive overlays create a polished attendee experience that G2 reviewers consistently describe as visually differentiated from standard webinar tools.
• Post-event content repurposing through its Content Lab feature generates clips, blog posts, and social assets from recordings.
• CRM integrations with Salesforce, HubSpot, and Marketo push engagement-level data (poll responses, CTA clicks, session duration) for lead scoring.
• Supports multi-session virtual summits and multi-day conferences with session tracks, sponsor hubs, and networking spaces.
Where it has gaps
• Goldcast was acquired by Cvent in December 2025. Product direction and integration roadmap post-acquisition remain to be confirmed, which may affect long-term planning for new buyers.
• The platform is primarily virtual-first. Teams running in-person or complex hybrid programs requiring onsite logistics (badge printing, check-in, lead capture hardware) need additional tools.
• Some G2 reviewers report that Marketo integration can be inconsistent with custom variable mapping and rate-limit handling.
Pricing: Custom pricing, requires sales conversation
Best for: B2B demand gen teams focused on producing branded virtual events with strong content repurposing workflows and CRM-connected engagement data, primarily for webinar-series and virtual summit formats.
Bizzabo
Bizzabo positions itself as an event experience operating system for enterprise B2B teams. Its virtual event capabilities sit within a broader platform that also covers in-person conferences and hybrid formats.
What it does well
• Unified event data across virtual, hybrid, and in-person formats provides consolidated reporting for teams managing complex portfolios.
• Real-time analytics dashboards and post-event engagement reports are among the more detailed in this category, per G2 reviewer feedback.
• Networking and attendee matchmaking tools support structured connection-building during virtual conferences.
• The platform supports scalable registration with multi-track session management for large virtual conferences.
Where it has gaps
• Landing pages rely on iframe-based architecture, which can block script tracking for GA4 and Bizible, creating attribution gaps for marketing ops teams.
• Customization options for event branding are more limited than platforms with full CSS/HTML access. Custom fonts and advanced design changes are constrained.
• Promo code and ticketing workflows have been flagged by reviewers for unexpected behavior, including auto-selecting incorrect ticket types when discount codes are applied.
Pricing: From $17,999/yr
Best for: Enterprise B2B organizations managing a portfolio of event formats (virtual, hybrid, in-person) that need unified data and reporting across the entire program, with attendee networking as a priority.
ON24
ON24 is an enterprise webinar and virtual engagement platform with deep roots in structured, analytics-heavy programs. It is one of the more established options for marketing teams running formal webinar series at scale.
What it does well
• Engagement analytics are among the most granular in this category, tracking poll responses, resource downloads, Q&A activity, and attention time at the individual attendee level.
• On-demand content hubs allow gated access to recorded sessions, supporting long-tail lead generation beyond the live event date.
• Compliance and certification workflows support continuing education use cases common in financial services and life sciences.
Where it has gaps
• ON24 is in the process of being acquired by Cvent. Post-acquisition product direction, pricing, and integration strategy may shift, which is a consideration for teams evaluating long-term commitments.
• The platform is primarily webinar-focused. Teams needing broader event management (in-person logistics, hybrid production, field event support) will require additional tools.
• CRM sync can experience delays, and some reviewers note that real-time data availability does not match what newer platforms offer.
Pricing: Custom pricing, requires sales conversation
Best for: Enterprise demand generation teams running high-volume, analytics-heavy webinar programs, particularly in regulated industries where compliance tracking and continuing education workflows are required.
Webex Events
Webex Events (formerly Socio) is Cisco's virtual and hybrid event platform, combining enterprise-grade security with event management capabilities. It is a common choice for organizations with existing Cisco infrastructure.
What it does well
• Enterprise security posture backed by Cisco's compliance certifications (SOC 2, ISO 27001, FedRAMP) satisfies IT and procurement requirements at large organizations.
• Multi-track session management, networking features, and gamification tools support complex virtual conferences.
• The mobile event app integrates with the virtual platform for a consistent attendee experience across devices.
Where it has gaps
• Marketing-specific workflows, including advanced CRM integrations and marketing automation connections outside the Cisco ecosystem, are more limited compared to platforms built specifically for B2B demand generation.
• Branding flexibility and advanced design customization options fall short for teams that prioritize pixel-level control over the attendee-facing experience.
Pricing: Custom pricing, requires sales conversation
Best for: Security-conscious enterprise organizations already operating within the Cisco ecosystem that need a compliant virtual event platform with strong mobile app support for large-scale conferences.
vFairs
vFairs is a virtual event platform known for immersive 3D environments that simulate in-person expo halls, trade shows, and career fairs. It serves both B2B and association markets across virtual and hybrid formats.
What it does well
• 3D virtual lobbies, auditoriums, and exhibit halls create a visual experience that differentiates from flat, browser-based event platforms. Reviewers on G2 consistently cite the immersive design as a standout feature.
• Exhibitor and sponsor booth management tools allow self-serve content uploads, lead capture, and attendee engagement tracking within individual booths.
• Support quality is among the highest-rated in this category, with dedicated event managers assigned to guide setup and live-day execution.
Where it has gaps
• The 3D environment comes with a steeper learning curve for both organizers and attendees. Initial setup requires more configuration than template-based platforms.
• CRM integrations and enterprise marketing automation connections are less developed than platforms purpose-built for B2B pipeline workflows.
• Pricing transparency is limited. Some reviewers note that custom design elements and specific features carry additional costs beyond the base package.
Pricing: Custom pricing, requires sales conversation
Best for: Organizations hosting virtual expos, trade shows, or career fairs that benefit from immersive 3D environments and structured exhibitor-attendee interaction, particularly in association and education markets.
Airmeet
Airmeet is a virtual events and webinar platform with a strong emphasis on attendee networking. Its virtual table and lounge features replicate informal conference interactions that most virtual platforms struggle to deliver.
What it does well
• Virtual networking tables allow attendees to move between group conversations freely, replicating the spontaneous interaction of in-person events. G2 reviewers frequently cite this as a primary differentiator.
• Branding customization spans the full attendee journey, from registration pages and email invites to virtual stages and networking lounges.
• The platform supports webinars, virtual conferences, and hybrid events within a single product, with engagement features like polls, Q&A, emoji reactions, and leaderboard gamification.
Where it has gaps
• Mobile experience for organizers and hosts could be improved, based on consistent G2 reviewer feedback.
• Enterprise CRM integrations, particularly with Salesforce for bi-directional sync and granular field mapping, are less mature than platforms that position CRM connectivity as a core differentiator.
Pricing: From $2,000 (webinars only)
Best for: B2B event teams running virtual conferences where attendee networking and community engagement are as important as content delivery, particularly for recurring community-building programs.
RingCentral Events
RingCentral Events (built on the former Hopin platform) is a virtual event solution within the broader RingCentral communications suite. It supports webinars, virtual conferences, and community events.
What it does well
• Built-in community hub features allow ongoing attendee engagement between events, supporting series-based programs and recurring audience interaction.
• The platform handles large audience capacities and supports multi-session formats with expo areas, networking spaces, and breakout rooms.
• For organizations already using RingCentral for communications, the unified billing and account management simplifies procurement.
Where it has gaps
• The platform's direction post-Hopin acquisition is still stabilizing. Some G2 reviewers note that the transition has introduced UI inconsistencies and feature changes.
• Real-time analytics and marketing-specific conversion features are less developed than dedicated B2B virtual event platforms.
• Backend configuration can feel complex for smaller teams or straightforward events.
Pricing: From $1,200 (webinars only)
Best for: Organizations with existing RingCentral communications infrastructure looking for a virtual event platform that supports community-driven engagement and recurring event series.
Zoom Events
Zoom Events extends the familiar Zoom Meetings experience into a structured virtual event platform with registration, ticketing, event hubs, and multi-session management. Its primary advantage is the near-zero learning curve for attendees.
What it does well
• Attendee familiarity with the Zoom interface reduces onboarding friction and no-show rates for teams whose audiences already use Zoom regularly.
• Event hubs centralize session management, registration pages, and on-demand content for multi-session virtual conferences.
• Stable, well-tested streaming infrastructure supports large attendee counts with consistent audio and video quality.
Where it has gaps
• Branding and customization options are notably limited. The virtual experience still closely resembles a Zoom meeting, which can reduce perceived brand differentiation for external-facing B2B events.
• Native engagement tools beyond chat and Q&A are minimal. Teams requiring live polls, gamification, or in-session CTAs typically need supplementary tools.
• Marketing automation integrations and CRM attribution capabilities are shallow compared to platforms built specifically for B2B demand generation workflows.
Pricing: Zoom Events add-on pricing requires a sales conversation
Best for: B2B teams that prioritize attendee convenience and low-friction access over advanced branding or CRM integration, particularly for internal events, training sessions, or straightforward webinar broadcasts at scale.
Hubilo (now VirtualPRO)
Hubilo (now VirtualPRO) is a virtual event platform designed for event marketers running programs where sponsor and exhibitor engagement is central to the event model. It supports webinars, virtual conferences, and hybrid events.
What it does well
• Sponsor and exhibitor tools include branded virtual booths, lead capture, resource distribution, and analytics dashboards, making it one of the stronger options for sponsorship-funded event programs.
• Interactive features like live chat, Q&A, polls, and emoji reactions support real-time audience engagement across session types.
• Integrations with CRM and marketing automation tools including HubSpot, Salesforce, Mailchimp, and Typeform push event data into existing workflows.
Where it has gaps
• Virtual event capabilities are gated behind the enterprise pricing tier. Lower-tier plans focus on webinar-only functionality, limiting flexibility for teams that need virtual conference features without enterprise budgets.
• Customization depth for branding, registration pages, and attendee-facing elements is less extensive than platforms that offer full CSS/HTML access.
Pricing: From $15,000/yr
Best for: Event marketers running sponsorship-funded virtual programs that require dedicated exhibitor management tools, branded sponsor booths, and self-serve analytics for sponsors.
What to look for in virtual event platforms for large-scale attendee experiences
These are the dimensions where virtual event platforms differ most for B2B teams. Weigh them based on which failure mode would hurt your program first.
Registration and landing page control
The platform should support branded, conversion-optimized registration pages without external web dev or iframe limitations. Losing UTM tracking at registration breaks attribution from the start.
Production studio depth
Pre-built scene flows, branded overlays, speaker transitions, and backstage controls separate professional virtual events from screen-share presentations. Without these, production quality drops.
In-session engagement tools
Look for native polls, Q&A, live CTAs, downloadable resources, and emoji reactions. If attendees are passive viewers, engagement data for sales follow-up does not exist.
Attendee networking capabilities
Structured networking (1:1 matching, virtual tables, breakout rooms) separates event platforms from broadcast tools. Without it, virtual audiences disengage faster.
CRM integration depth
Bi-directional sync with Salesforce, HubSpot, or Marketo should push granular engagement data, not just registration records. Delayed sync creates follow-up latency.
Content repurposing workflow
Automatic generation of on-demand recordings, clips, and derivative content assets matters. Manual post-production delays reduce the content lifecycle of every session.
Branding and design flexibility
Full CSS/HTML access, custom fonts, and embeddable widgets keep the event experience consistent with your web presence. Locked templates limit brand differentiation.
Analytics and revenue attribution
Session-level engagement data, pipeline dashboards, and exportable reports determine whether the event team can prove ROI to leadership. Basic attendance counts are insufficient.
Scalability across formats
If you run webinars today and plan conferences or hybrid events later, evaluate whether the platform supports those formats natively or requires a separate tool purchase.

Questions people ask about virtual event platforms
What is a good virtual event platform for B2B marketing teams?
Zuddl, Goldcast, Bizzabo, and ON24 are commonly evaluated by B2B marketing teams. The right choice depends on whether the priority is production quality, CRM integration depth, content repurposing, or multi-format event support. Teams running conferences alongside webinars benefit from a unified platform.
What should a virtual event platform integrate with?
At minimum, CRM (Salesforce, HubSpot), marketing automation (Marketo, Eloqua, Pardot), and communication tools (Slack). Bi-directional data sync with real-time engagement signals is what separates pipeline-impacting integrations from basic data exports.
What is the difference between a virtual event platform and a webinar tool?
Webinar tools focus on one-to-many broadcast sessions. Virtual event platforms add multi-session agendas, networking environments, sponsor areas, attendee segmentation, and deeper CRM attribution. If events need to produce pipeline data, a webinar tool alone is typically insufficient.
How do you evaluate virtual event platforms for large-scale attendee experiences?
Start with CRM integration depth and production quality. Then evaluate registration flexibility, engagement tools, and post-event analytics. Test with a live pilot before committing. The failure modes that matter most are data sync delays and branding limitations.
