The Best AI Webinar Platforms for Small B2B Lead-Gen in 2026
We compared six of the webinar platforms small B2B teams actually consider, scoring them on current official pricing, attendee caps, AI tooling, and how cleanly a registrant turns into a lead in your CRM.
By Priya Raman, Lead Reviewer · Updated October 10, 2026 · 6 tools tested
The Verdict
For most small B2B teams running monthly or biweekly lead-gen webinars under 100 live attendees, Riverside's Webinar plan is the sharpest buy: $79/month billed annually, with branded registration, Q&A, polls, email reminders, HubSpot sync, and 4K local recording for repurposing, all in one subscription. If you expect 100-500 live attendees and want a familiar webinar experience built around marketing analytics, Demio is the pick. If you're already locked into the Zoom ecosystem and just need a reliable broadcast on top of your existing seats, Zoom Webinars is the safe default, but it's a broadcast tool, not a lead engine.
Webinars are still one of the highest-intent lead sources a small B2B team has. A good one captures 100-400 registrants, lands 30-40% of them on the live session, and drops them into your CRM warm, educated, and ready for a sales conversation. The platform you pick either amplifies that or quietly adds friction: missing reminder emails, broken replay links, surprise overage bills, or a registrant list stranded inside a tool your CRM can't read.
We looked at the six webinar platforms small B2B marketing teams actually shortlist in 2026: Riverside Webinar, Demio, Livestorm, WebinarJam, Zoom Webinars, and GoTo Webinar. Rather than claim a lab test we didn't run, we read each vendor's current official pricing and feature pages, compared plan structure for a small team hosting one webinar per month to 100-500 live attendees, checked where lead data actually goes, and scored each on the trade-offs that matter when the goal is pipeline, not internal training videos. Here's how we evaluated them, and how each one stacked up.
How We Tested
This is a documentation and pricing comparison, not a hands-on lab test. For every platform we read the vendor's current official pricing page and feature docs, modeled the realistic cost for a small B2B team running one lead-gen webinar per month at 100-500 live attendees, and scored each tool against the seven criteria below. Scores are stored 0-100 internally and shown as /10.
Lead-Gen Fit
We checked whether each platform includes the lead-gen essentials for a small B2B team at its entry paid tier: a branded registration page, automated email reminders, Q&A, polls, post-event analytics, and a native CRM sync. If a core piece required an upgrade or a third-party tool, we docked the score.
Pricing Transparency
We opened each vendor's live pricing page and recorded the published monthly and annual prices, attendee tiers, and any prerequisite base plans. Tools with fully self-serve, published pricing scored higher than tools that gate anything meaningful behind 'contact sales.'
True Cost at 100-500 Attendees
We priced the realistic annual commitment for a small B2B team on each vendor's cheapest plan that supports up to 500 live attendees, counting any required base plan, per-attendee credits, or add-on seats, and converted everything to a single USD/year figure using the published annual price.
Automation & Evergreen
We checked whether each platform supports automated/pre-recorded webinars that look live, and at which plan tier that feature unlocks. A webinar you can record once and run on autopilot is a different lead-gen asset than a one-and-done live broadcast.
AI & Repurposing Tools
We read each vendor's current docs for built-in AI features that help a small team turn one 45-minute webinar into clips, transcripts, blog posts, or follow-up emails. Platforms with native AI editing, chaptering, or content repurposing scored higher than platforms that only produce a raw MP4.
CRM & Marketing Integration
We checked each platform's documented integrations with the CRM and email tools small B2B teams actually use (HubSpot, Salesforce, Marketo, Pardot, Mailchimp), and specifically whether a registrant lands in the CRM as a lead with their answers to the registration form attached. We penalized tools that gate CRM sync behind the top tier.
Setup & Ease of Use
We checked whether attendees can join without friction, how long it takes to spin up a first webinar from signup to registration link, and whether the host workflow is self-serve or requires a sales-led onboarding. Tools with same-day setup scored highest.

Livestorm
by Livestorm
Teams running small, infrequent, or low-no-show webinars
7.6/10★★★⯪☆
A polished browser-based webinar platform with a per-attendee pricing model that gets expensive fast once your lead-gen webinars start working.

Why We Like It
Browser-based attendee experience with strong CRM integrations
Pay-per-attendee model is efficient when registration-to-attend rates are low
Watch Out For
Pro plan charges €2.50 per attendee credit, so a 400-person webinar quickly adds significant cost on top of the subscription
Replay and on-demand viewers each consume a credit per session, so promoting replays increases your bill

GoTo Webinar
by GoTo
Established teams who want a dependable broadcast at 250-500 attendees
7.2/10★★★⯪☆
A reliable, long-standing webinar platform with generous attendee caps on the entry plan. The dated interface and lack of native AI tooling make it hard to recommend over Riverside or Demio for a modern small B2B team.
Best for: Established teams who want a dependable broadcast at 250-500 attendees
Why We Like It
Reach plan documented at $59/mo billed annually for one organizer and up to 500 participants in some vendor-published breakdowns
Full registration, automated emails, polls, Q&A, and analytics are built in
Flex pay-per-event option exists for teams that run fewer than one webinar per month
Watch Out For
No permanent free plan
Interface and templates feel dated against Riverside, Demio, and Livestorm
No native AI content-repurposing tooling at the plan tiers small teams actually buy

Zoom Webinars
by Zoom
Teams already standardized on Zoom
7.0/10★★★⯪☆
The default broadcast tool for teams already paying for Zoom. Reliable, familiar, and a safe choice if your audience already knows the interface. But it's a broadcast layer, not a lead-gen funnel.
Best for: Teams already standardized on Zoom
Why We Like It
Lowest-friction choice for an audience that already knows how to join a Zoom link
Supports both standard Webinars and a Webinars Plus tier with Simulive, backstage, and AI content tools
Scales cleanly from a 500-attendee broadcast up to very large events on higher plans
Watch Out For
Pricing structure has moved several times in 2026; plan names and attendee tiers reorganized mid-year
Weaker native marketing stack: registration and nurture usually need to be stitched together with another tool

What a small B2B team actually needs from a webinar platform
Four things, in this order. First, a branded registration page you can send ad traffic and newsletter traffic to without embarrassment. Second, automated email reminders that recover the 60-70% of registrants who would otherwise forget. Third, a clean handoff of registrant data into your CRM, ideally HubSpot or Salesforce, so a webinar lead ends up in the same nurture flow as every other lead. Fourth, a replay and a way to turn 45 minutes of talking into clips, a transcript, and a follow-up blog post without a separate production team.
Platforms that solve all four at a predictable monthly price win. Platforms that nail the broadcast but leave you stitching Zapier, Mailchimp, and a landing page builder together to recover lost registrants are a false saving. The $79 you pay for a dedicated webinar plan is almost always cheaper than the hours a founder spends hand-exporting CSVs from a tool that was built for internal meetings.
Pair your webinar with the rest of your lead-gen stack
A webinar on its own is a channel, not a funnel. The two things most likely to lift your registration-to-lead conversion are a dedicated landing page for the webinar topic (see our guide to AI landing page builders for small-business lead capture) and distribution. Schedule the promo posts across LinkedIn and X in advance with an AI social media scheduler so you’re not writing the “join us tomorrow” post at 11pm the night before. The webinar replay and transcript are also the single highest-leverage input into an AI blog post generator. One 45-minute session can seed three or four SEO posts, a LinkedIn carousel, and a four-email nurture sequence if you have the raw transcript to hand.
A note on the pricing numbers in this guide
Webinar pricing moved a lot in 2026. Zoom restructured its webinar and events plans mid-year, GoTo renamed its tiers, and most vendors now publish both a monthly and an annual rate with a 20-30% gap between them. The numbers in this guide are the prices each vendor published at the time we checked. Open the vendor’s pricing page before you sign anything, model the realistic attendance for your webinar (be honest, assume 30-40% of registrants show up live), and buy one tier up from what you think you’ll need. Running into an attendee cap mid-webinar is the one failure mode that no amount of post-event analytics will fix.
Frequently Asked Questions
What's the best webinar platform for a small B2B team running monthly lead-gen webinars?
For most small B2B teams under 100 live attendees, Riverside's Webinar plan at $79/month billed annually is the sharpest buy. It includes branded registration, lead capture, Q&A, polls, email reminders, webinar analytics, and a native HubSpot integration, which are the pieces that turn a webinar into a demand-gen asset instead of a Zoom call. If you need 100-500 attendees and prefer flat per-plan pricing with no per-attendee meter, Demio and WebinarJam are the next picks.
Is Zoom Webinars a good choice for a small B2B lead-gen program?
Only if you're already paying for Zoom and your audience is used to joining Zoom links. Zoom is a broadcast tool, not a lead-gen funnel. You'll still need a landing page, email nurture, and CRM sync stitched together separately. Riverside, Demio, and WebinarJam ship those pieces in the box.
How does Livestorm's per-attendee pricing actually work?
On Livestorm's Pro plan, you pay €2.50 per attendee credit, and one credit is one unique person per session. Anyone who watches a replay or on-demand recording also consumes one credit per session, so promoting replays increases your bill. Buy against a realistic attendance forecast, not your best-case turnout.
Which webinar platform is cheapest for 500 live attendees?
WebinarJam Basic at $79/month billed annually ($948/year) is the strongest capacity-per-dollar option that handles 500 live attendees, and the plan includes 5 additional team-member seats and 2-hour sessions. GoTo Webinar's Reach plan is also documented at around $59/month billed annually for up to 500 participants in current vendor-published breakdowns.
Do I need automated/evergreen webinars for lead gen?
Not day one, but you'll want them within six months. The classic small-B2B pattern is to run a webinar live two or three times, learn what questions keep coming up, then record the best version and let it run on autopilot as evergreen while you build the next topic. Demio's Growth tier, WebinarJam's Basic tier, and Riverside's Webinar plan all support pre-recorded sessions that run as live. Zoom Webinars Plus and Livestorm Pro also support this. GoTo Webinar's current plans are weakest here.
