What Is the Core Difference Between a Webinar and a Roundtable?
A webinar is a broadcast format: one or a few presenters deliver content to a larger audience (typically 100-500+ registrants). Attendees watch, send questions to the moderator, and may participate in polls. The experience is largely passive.
A roundtable is a facilitated peer discussion: 10-25 participants share equal voice in a structured conversation moderated by an expert host. The experience is active, collegial, and exclusive.
Both formats generate B2B pipeline through live event engagement. They work on different buyer segments and at different cost and scale points.
Which Format Works Best for C-Suite and VP-Level Buyers?
Roundtables win decisively for senior buyers. A CISO, CFO, or VP Engineering will set aside 60 minutes for a curated conversation with 10-15 verified peers on a problem they are actively solving. They will not set aside 60 minutes for a 300-person webinar where they are audience members watching a vendor presentation.
The exclusivity and peer composition are the value proposition for senior buyers. LinkedOtter roundtable programs produce 38 C-level and VP-level attendees from 1,266 target prospects. Those attendees convert to qualified meetings at rates that broadcast webinars cannot match at the senior level.
For C-suite targeting, roundtable attendance at 25-40% of invites is achievable when the topic is specific and the peer list is curated. Webinar attendance from cold invites to C-suite typically runs at 2-5%.
Which Format Works Best for Director and Manager-Level Buyers?
Webinars win at scale for mid-level buyers. Directors of DevOps, Heads of Security Engineering, and Marketing Operations Managers respond well to webinars because the content is educational and the time commitment is limited.
The 2026 benchmark shows webinars attracting 300 average registrations at 40-50% live attendance (Livestorm, 2026). For director and manager-level personas, a well-promoted webinar on a specific technical or operational topic produces strong pipeline volume at a lower cost per lead than roundtables.
WebinarS are also better for top-of-funnel awareness. A 400-person webinar reaches 400 people in your ICP; a 20-person roundtable reaches 20. If your goal is market presence and top-of-funnel awareness, webinar scale matters.
What Does Each Format Cost?
Webinars:
- Production cost: $1,500-5,000 per event for mid-quality production
- Promotion cost: $2,000-8,000 for LinkedIn ads and email sequences
- LinkedOtter programs: starting at $6,000 end-to-end for ICP-targeted invite lists, production, and post-event follow-up
- Cost per lead: approximately $72 (2026 Livestorm benchmark)
Roundtables:
- Production cost: typically $3,000-8,000 for premium facilitation and virtual platform
- Attendance list: 20-30 verified senior buyers (harder to fill, higher value per seat)
- Cost per qualified meeting: lower than webinars because seniority is higher
- LinkedOtter programs: starting at $6,000 for curated executive roundtables
What Conversion Metrics Should You Compare?
| Metric | Webinar | Roundtable |
|---|---|---|
| Average registrations | 300 | 20-30 (invites) |
| Live attendance rate | 40-50% | 25-40% (senior invites) |
| Buyer seniority | Director and below | VP and C-suite |
| Pipeline per event | High volume, moderate quality | Lower volume, high quality |
| Cost per qualified meeting | $140-300 | $200-500 |
| Sales cycle from event | 45-90 days | 30-60 days |
Which Format Should You Choose?
Run roundtables if: you are selling into C-suite or VP-level, your deal sizes are $50,000+, you have a specific account list of 50-200 target companies, or you need to build deep trust before a commercial conversation.
Run webinars if: you are building top-of-funnel awareness, targeting director-level and below, running a high-volume pipeline model, or need to demonstrate category leadership at scale.
Run both if: you have both a high-ACV enterprise motion (roundtable) and a mid-market or PLG motion (webinar), and you want to cover the full buyer seniority spectrum.
LinkedOtter runs both formats for clients depending on ICP seniority and deal size. The standard recommendation: start with a webinar to build your audience, then run an invitation-only roundtable for your highest-value accounts.
