You don't need help running the event. You need help filling it.
We fill your B2B webinars and events with qualified buyers, then keep the no-shows warm until the next one.
Hosting a webinar is the easy part.
You already know this. You picked the date, the topic, the speaker. You set up the Zoom. You built a registration page. None of that was the hard part.
The hard part is who actually shows up.
You put a real budget, real prep, and your team's calendar into the event. What you got back was a registration list, not a pipeline.
That is the actual problem. Filling the room with the right buyers, then doing something useful with everyone who said yes. That is the work that almost never gets a real owner inside the company.
An event should be a sales channel, not a logistics project.
The job is simple to state. Get the right buyers into the room. Get their information. Get a real conversation going with the ones who are ready, and stay close to the ones who are not.
We do all of that. You host the event. We fill it, capture it, and follow it through.
You run the event. We fill the room.
Four stages. Built around your event.
We plug into your event timeline and run the demand side end to end.
We design and write the assets that pull people in: landing page, promotional copy, email sequences, social creative, the angle that makes the event worth a senior person's hour.
Distributed through our publications and through precise paid targeting to your exact ICP. The right roles, the right industries, the right geographies, no spray.
Every registrant is tracked, enriched, and tagged with intent signals. The sales-ready ones get routed to your team while interest is hot.
30% of registrants will not attend live. We keep them in a structured follow-up. The ones who slip through one event become the audience for the next one.
What this looks like in practice.
SuiteConnect México 2026: filling the room with senior finance leaders.
Demand campaign run end to end through El CFO Latinoamericano, our publication for finance leadership across Latin America.
Senior finance leaders captured for the event
Of target. Over-delivered on the committed number.
Days of execution. From kickoff to event day.
The work included following up with every registrant to help them move through Oracle's own registration flow, which required two separate forms. We did not just promote the event. We made sure our client got results.
Three reasons most events fail.
A blast that says 'join our webinar' is an ad. We build the angle that earns a senior person's attention before they ever see the registration page.
Companies promote into the same database every quarter and wonder why open rates fall. We use our publications and precise paid distribution to reach buyers who are not yet on your list.
The replay link goes out, then silence. We treat the no-show audience as the start of the next cycle, not the end of this one.
This is built for a specific kind of company.
- You run B2B webinars, executive roundtables, or live events as part of your demand strategy.
- Your target audience is senior, specific, and hard to fill the room with through your own list.
- You sell a considered product with a deal size of at least $60K a year.
- You want the registration list to turn into pipeline, not sit in a CRM.
- You are a B2C company.
- You run consumer-facing events or livestreams.
- Your lead generation budget is below $2K a month.
- You need the event filled in under two weeks. Good events take real runway.
What a Castleberry event engagement includes.
Most demand agencies rent attention on channels they do not own. We do not. Every Castleberry event campaign runs through our own portfolio of niche B2B publications, each one built around a specific industry and audience. For Oracle NetSuite, that meant El CFO Latinoamericano. For your event, we match the publication to your buyer.
Distribution through our own publications — the editorial channels we operate for senior decision-makers in your category.
- A custom landing page and registration funnel built around your event.
- Email sequences for pre-event promotion, day-of activation, and post-event follow-up.
- Precise paid distribution layered on top of the publication reach, to your exact ICP.
- A live dashboard of registrations, enrichment, and intent data.
- Fast handoff of sales-ready leads to your team while interest is hot.
- A structured no-show nurture track that holds the audience for your next event.
