9 Top B2B Webinar Companies, Agencies & Services (2025 Guide)
Webinars have become a full-funnel growth engine in 2025, and the numbers back it up. A full 73% of B2B marketers say webinars generate their highest quality leads, and 68% of marketers can tie webinar campaigns directly to revenue. Whether used to attract new prospects, educate existing customers, or accelerate pipeline opportunities, webinars give marketing and sales teams a scalable way to build trust, deliver value, and drive action.
But running a high-performing B2B webinar takes a coordinated strategy that includes speaker coaching, funnel alignment, live engagement tools, post-event nurture, and AI-powered content repurposing. For teams without deep in-house resources, partnering with a specialized webinar agency can be the difference between flat attendance and pipeline-driving results.
In this guide, we’ve done the hard work for you, vetting the top webinar agencies and service providers built specifically for the B2B market. We’ll also discuss:
What a B2B webinar agency actually does
Benefits of partnering with a webinar agency
How to choose one
Webinar platforms vs. agencies (plus some good webinar platforms to consider)
Whether you're launching your first webinar series or looking to scale an existing program, this list will help you find the right partner to turn webinars into a repeatable revenue channel.
Let’s get started.
What Does a B2B Webinar Agency Actually Do?
A B2B webinar agency handles everything from strategy and speaker prep to promotion, production, and lead follow-up. Instead of juggling tools and tasks in-house, you get a team that turns webinars into qualified pipeline faster. Read on to see what they do behind the scenes.
Strategy: Topic Research, Funnel Alignment, Audience Targeting
A great B2B webinar starts with strategy. Agencies help define the purpose of the webinar, align it with your sales funnel, and identify topics that resonate with your ICP. They conduct audience research, analyze funnel gaps, and develop session formats designed to attract and convert. This upfront planning ensures the webinar drives more registrations but also contributes to qualified pipeline and sales-ready conversations.
Production: Speaker Coaching, Run-of-Show, Live Broadcast
Webinar agencies manage everything behind the scenes to ensure a smooth delivery. That includes coaching internal or external speakers, scripting transitions, and building a structured run-of-show. On the technical side, they handle the live production environment, from platform setup to managing Q&A, polls, and backup streams.
The result is a polished, professional experience that reflects your brand and keeps attendees engaged through every stage of the event. Actually, audiences hang around for about 51 minutes on average during live webinars, which shows just how effective expert production can be at holding attention.
Promotion & Distribution: Email, LinkedIn, Paid Boosts, AI Clip Factory
Driving attendance takes more than a registration page. Webinar agencies run multichannel campaigns using email marketing, LinkedIn content, and paid ads to attract the right audience. Post-event, they turn webinar recordings into clips, reels, and thought leadership assets using AI-powered tools.
In fact, 65% of marketers repurpose webinar content as a cost- and time-saving way to build an audience, and they often generate 6+ extra pieces of content from each session. These repurposed assets extend reach, nurture leads, and drive continued engagement long after the live broadcast ends, turning one event into dozens of content pieces.
Measurement: Registration→Attendance, Lead Quality, Revenue Attribution
Agencies track and optimize every stage of performance from registration rates and attendance drop-off to engagement, lead quality, and post-event conversions. They integrate webinar data with your CRM or marketing automation platform to attribute pipeline and revenue accurately.
With the right partner, you get dashboards and insights that show exactly how each webinar performs across the funnel so you can prove ROI and continuously improve future campaigns.
And here’s a helpful stat to underscore why that tracking matters: the average webinar attendance rate hovers around 35–45%, meaning about half of your registrants actually show up, making those funnels and dashboards critical for understanding performance.
Benefits of Partnering With a Webinar Specialist in 2025
The global virtual events market is on track to surpass $1 trillion by 2035, and B2B marketers are doubling down on what works: webinars. Here’s why working with a webinar specialist pays off.
Higher Attendance Rates (40–55% vs DIY 25%)
Webinar agencies routinely outperform DIY teams, delivering attendance rates of 40% and higher with top-tier programs peaking at 66%. In contrast, self-run webinars often struggle to cross the 25% threshold.
One key reason is smarter targeting. B2B-focused agencies know how to promote across LinkedIn, paid media, and intent data lists. With 73% of B2B marketers stating webinars generate high-quality leads, it’s clear that getting the right audience is what drives results.
AI-Driven Content Repurposing Saves 13K Hours / $650K Yearly
Specialist webinar partners now use AI to automatically repurpose events into clips, quotes, transcripts, blog posts, and sales enablement assets. This shift saves teams 13,000 hours or $650,000 annually, according to some sources.
This repurposing capability also supports mobile-first distribution and on-demand workflows, which are critical in a landscape where hybrid and mobile formats dominate. In 2025, the most effective webinar strategies are now multi-channel engines.
Compliance & Security: GDPR, SOC 2, ISO-27001 (must-have for SaaS & FinServ)
Webinar partners with experience in regulated sectors also offer compliance. Platforms and agencies serving SaaS, finance, and healthcare clients must adhere to GDPR, SOC 2, and ISO‑27001 standards. They are necessities for safeguarding data, maintaining reputational integrity, and winning enterprise trust.
Lead Conversion: 20‑40 % of Attendees Become SQLs
A critical metric is attendee-to-SQL conversion. Specialists deliver significantly better results, achieving 20% to 40% conversion rates in our experience. DIY efforts get lower success rates because specialist firms can align content, follow-ups, and sales handoffs better. This means up to 4 in 10 attendees may enter your sales pipeline, turning webinars into powerful revenue generators.
How to Choose a Webinar Partner
When selecting a webinar partner, evaluate each against these essential criteria to ensure they align with your goals and tech ecosystem:
Key Evaluation Criteria (Capacity, Engagement Tools, Integrations, Security)
Capacity & streaming quality: Look for platforms that support at least 1,000 live attendees for mid-market events, with adaptive HD video and less than 300 ms latency. Enterprise-grade platforms like ON24 and BigMarker scale to 50,000+ or even 500,000 attendees, depending on use case.
Engagement tools: Engagement features like live polls, Q&A, surveys, and reactions significantly boost conversion. As we said before, best-in-class webinars report engagement rates of 40–60%, measured by chat activity, poll responses, and average watch time.
Analytics & reporting: Your vendor should offer real-time dashboards, post-event engagement scores, and integrations with attribution tools. Look for conversion funnel visibility from registration to attendance to follow-up engagement, with metrics like:
Average watch time over 35 minutes
Q&A participation above 25% of attendees
Replay views exceeding 30% of registrants
Integrations: Native integrations with CRMs like Salesforce, HubSpot, and marketing tools like Marketo or Pardot are must-haves. Avoid platforms that rely on complex API-only connections. Ideally, the platform should push lead scores and engagement data within minutes of webinar conclusion.
Security & compliance: Confirm your vendor meets:
GDPR compliance for EU attendees
SOC 2 Type II certification for data handling
ISO/IEC 27001 for information security
Enterprise buyers should also ensure multi-factor authentication and single sign-on (SSO) capabilities are available.User experience (mobile + desktop): In 2025, mobile-first access is critical. Platforms should offer browser-based attendance with no downloads and maintain over 99.9% uptime. There are no exact industry figures yet, but mobile-friendly webinars increase attendance rates because you gain access to a larger audience.
Evaluating vendors against these data-backed criteria will help you avoid underperforming platforms and set a solid foundation for conversion-driven webinars.
Pricing Models Explained: What B2B Marketers Should Expect in 2025
Webinar pricing in 2025 is far from one-size-fits-all. Your ideal cost structure depends on audience size, production complexity, frequency, and whether you're managing it internally or outsourcing. Below is a breakdown of the most common pricing models, real-world ranges, and the hidden costs to watch for.
Core Pricing Models
Most webinar platforms and agencies offer one of three billing structures:
Per-host: You pay a fixed monthly fee per presenter. Platforms like ClickMeeting start at $49/month for 100 attendees, while Livestorm charges $95/month for 300 participants. This is ideal for frequent, internally run webinars.
Per-attendee: Costs scale with registrant or viewer count, often $0.50 to $5 per attendee. Providers like Cvent and BigMarker offer flexible volume-based pricing.
Flat-fee / Enterprise: Full-service agencies charge a flat rate that includes everything from event planning to post-event content. Expect $2,000 to $7,000 per webinar. Agencies like Content Allies offer monthly bundles for ongoing webinar series.
Typical Budget Ranges for Mid-Market Teams
If you're a mid-sized B2B company aiming for results-driven webinars:
DIY or hybrid production: $2,000–$5,000 per webinar, factoring in internal labor, freelance support, and tool subscriptions.
Agency-managed webinars: $5,000–$10,000 per event, inclusive of strategy, promotion, and content repurposing.
Retained programs: Ongoing packages average $3,000–$7,000 per month for 1–2 webinars with full-service support.
Hidden Costs That Impact ROI
Even polished platforms come with less-visible expenses:
Overage charges: Going beyond attendee caps (e.g., from 500 to 700 viewers) can add $100–$400+ per event, according to WebinarNinja.
Production add-ons: Branded studios, multi-host setups, live translation, or AI-generated clips often increase pricing by 30–50%.
Analytics licenses: Advanced reporting or multi-user dashboards can cost $200–$1,000/month, especially on enterprise tools like ON24 or Cvent.
Email & CRM integration: Some vendors limit email sends or charge extra for connecting with tools like Salesforce or HubSpot.

What sets Content Allies apart is their end-to-end approach. They help you produce a webinar or podcast, sure, but more importantly, they align the entire program with your business goals. Their strategists design content blueprints that map directly onto your funnel, whether that means transforming webinar archives into episodic content or launching a live series from scratch. Every step is supported by detailed audience targeting, CRM integration, and a BI dashboard that lets you measure engagement, downloads, and pipeline contribution.
Execution is just as white-glove. Content Allies takes over production completely, handling recording support, audio and video editing, transcription, branding, and publishing to channels like YouTube, LinkedIn, and podcast platforms.
A webinar recording doesn’t just end when the event is over; it gets repurposed into short clips, audiograms, blog articles, and SEO assets that extend its reach far beyond the live audience. Their team also manages guest outreach and scheduling, consistently securing executive-level voices from global enterprises and thought leaders to boost credibility for each session.
Promotion is another key strength. Content Allies amplifies each webinar or podcast through organic campaigns across social platforms, targeted PPC and firmographic advertising, and evergreen SEO content. The result is that one event multiplies into dozens of assets, creating multiple entry points for prospects.
On top of that, they provide clear attribution with quarterly reviews and a live dashboard, so marketing and sales teams can track exactly which companies and roles engaged, and which converted into revenue.
Their process mirrors what you’d expect from a top-tier webinar partner: strategy, production, promotion, repurposing, and ROI tracking. Only it’s delivered with the added sophistication of a media agency that has already proven its impact with some of the world’s biggest brands.

Enterprise-Level Platforms
In this guide, we still recommend full-service B2B webinar agencies, but here’s a quick look at some enterprise-grade platforms you might hear about and why they only solve part of the problem.
ON24
ON24’s Intelligent Engagement Platform supports live webinars (up to 2,500 standard attendees, scalable to tens of thousands) and AI-powered personalization and content repurposing through its Analytics and Content Engine (ACE). According to ON24, AI-generated content drove 7× more audience engagement in 2024, and personalized experiences generated 4× more demo requests than generic ones.
However, ON24 still requires in-house teams to craft strategy, coach speakers, promote the event, and follow up on leads. An all-in-one agency can deliver more turnkey support.
BigMarker
BigMarker is a browser-first platform known for its unmatched scale and ease. It can support up to 500,000 attendees and includes interactive features like polls, Q&A, automated webinars, onboarding custom landing pages, and mobile check-in, all earning a 4.7/5 on G2.
Still, it’s primarily a scalable tool. Without a strategic partner to run campaigns end-to-end, conversion rates and lead follow-up can suffer.
Hubilo
Hubilo combines live webinar experiences with hybrid-style hubs and AI-led content repurposing. Its “Snackable Content Hub” automatically creates up to 50 clips, blog posts, and social assets right after each event.
While that unlocks ongoing value, teams still need support with topic development, messaging, list-building, and sales integration, which an agency like Content Allies can fully deliver.
Mid‑Market Solutions
While full-service agencies are your safest bet, here are some mid-market webinar platforms that teams commonly consider, although they still require strategic and operational support:
Zoom Webinar
Zoom Webinar is a widely adopted tool for broadcasting polished virtual events. It supports up to 50,000 view-only attendees and 1,000 panelists, offering features like custom registration, branding, polls, Q&A moderation, and virtual backgrounds. Its ease of use, reliability, and global reach make it a natural fit for teams already using Zoom. Still, without agency support, it lacks a built-in funnel strategy, promotion, and follow-up workflows.
Airmeet
Airmeet focuses on creating interactive experiences with features like virtual "Social Lounges," speed networking, breakout rooms, emoji reactions, and robust event analytics. It offers full white-label customization and mobile access, which are ideal for mid-market teams looking to increase engagement. But without a specialist to generate content, manage audience outreach, and drive post-event conversion, it remains a tool, not a comprehensive solution.
GoToWebinar
GoToWebinar includes features critical to mid-market and enterprise teams: up to 3,000 live attendees, detailed source tracking with unique registration URLs, and enterprise-grade security and privacy standards, including SOC 2 and ISO‑27001 compliance. It’s reliable and scalable, but lacks agency-level services like webinar promotion, speaker coaching, and funnel optimization.
Why Agencies Still Win
Platforms like ON24, BigMarker, and Hubilo are powerful tools when you already have a strategy, promotion, speaker support, and sales follow-up internally. But most B2B teams lack those capabilities in-house. A full-service agency offers:
End-to-end planning and funnel alignment
Speaker coaching and live event management
Multichannel promotion and ABM prioritization
Post-event nurture, clip repurposing, and revenue attribution
Following the right KPIs and optimizing your webinar to meet them
A platform alone leaves critical work on your plate. A specialist partner turns webinars into a scalable, revenue-driving asset.

Frequently Asked Questions
Still deciding whether to bring in an agency or run webinars in-house? Here are answers to common questions that come up when evaluating webinar partners.
What’s the Minimum Budget for a High-Quality B2B Webinar?
For mid-market and enterprise companies, expect to spend $2,000 to $10,000 per webinar, depending on your goals, audience size, and services included. That budget typically covers strategy, promotion, production, speaker prep, and post-event content. Agencies often offer package pricing for webinar series, which can reduce per-event costs and improve performance over time.
How Many Attendees Justify Using an Agency Over DIY?
If your webinars target more than 100 registrants or are designed to support revenue goals, an agency is worth the investment. Agencies boost attendance rates to 40–55% versus the DIY average of 25% and can convert 20–40% of attendees into qualified leads. For sales-focused webinars, those metrics alone justify the upgrade.
Do I Need a Separate Video Platform for On-Demand Hosting?
Most webinar platforms include basic replay hosting, but if you want full control over branding, analytics, or gated content, a dedicated on-demand solution like Wistia, Vimeo, or Hubilo may be necessary. Agencies can handle this for you, ensuring replays are optimized for lead capture, SEO, and continued nurturing.
Which KPIs Matter Most to the C-Suite?
Focus on metrics that map directly to the pipeline and revenue. That includes:
Registration-to-attendance rate
MQL and SQL conversion
Influenced or sourced pipeline
Revenue attribution
A good agency will integrate with your CRM or marketing automation tools to surface these metrics clearly so you can report results that actually matter.
