A practical comparison for B2B teams planning CXO dinners, executive roundtables and thought leadership events
The best B2B executive event agency is not simply the one with the most impressive venue list. It is the partner most capable of bringing the right senior decision-makers into a credible room, creating a conversation worth attending and turning the resulting relationships into commercial momentum.
For B2B companies selling complex, high-value solutions, an executive dinner or roundtable can create access and trust that cold outreach rarely achieves. But agencies differ significantly. Some specialise in global scale, some in tightly curated London dinners, some in premium event production, and some in pipeline generation after the room clears.
This guide compares credible UK options on their publicly stated offer. It is designed to help field marketing, demand generation, ABM and enterprise sales leaders build a shortlist—not to pretend that one agency is right for every brief.
Before comparing names, agree what success means. A beautiful evening with the wrong attendees is not a successful enterprise event. Equally, a full room can underperform if the topic, format and follow-up do not create a reason for buyers to continue the conversation.
Use these criteria when assessing agencies:
CXO & Co designs curated executive dinners and thought leadership summits for B2B companies that want access to specific senior buyers. Its proposition starts with the target audience and commercial objective, then brings together event strategy, delegate acquisition, premium delivery, facilitation and post-event pipeline support.
Its executive dinner format is designed for 12–15 C-level and VP attendees, while thought leadership summits are designed for 50–100 directors, heads of department and senior leaders. CXO & Co publicly commits to minimum attendee numbers and says it arranges one-to-one meetings with interested attendees after the event.
Best for: B2B companies selling high-value enterprise solutions, especially where named-account access, seniority and post-event meetings matter as much as the event experience.
Considerations: CXO & Co deliberately focuses on curated, premium formats rather than large exhibitions or broad consumer-style event production.
The Ortus Club runs executive dinners and roundtables in London and internationally. Its London offer emphasises small peer groups, typically 8–15 attendees at a similar seniority level, with a no-vendor-pitch environment and strong venue knowledge.
Its public London page highlights experience delivering programmes for global technology brands and established relationships with premium venues. This makes it a credible option for companies that want to repeat a consistent executive-event format across several international markets.
Best for: Enterprise technology companies seeking an experienced global partner, repeatable city programmes and intimate peer-level discussions.
Considerations: Buyers should clarify how target-account approval, meeting generation, exclusivity, programme ownership and post-event sales follow-up work for their specific package.
Kinetic Alliance offers CXO dinners, day events, virtual roundtables and virtual events for ABM and demand generation teams. Its positioning combines bespoke, relationship-led service with delivery across EMEA and North America.
The agency describes 8-, 10- and 12-person private dinner formats, premium venues and a process built around the client’s priorities, target audience and desired outcomes. It is particularly relevant for teams that want a choice of intimate in-person and virtual executive engagement formats.
Best for: ABM and field marketing teams looking for tailored executive dinners or roundtables across the UK, EMEA and North America.
Considerations: Ask how attendee guarantees, named-account recruitment, post-event meetings and pipeline attribution are defined before comparing proposals.
ConvergeX Connections positions itself as a London B2B event marketing agency for enterprise technology brands. It runs executive dinners, roundtables, virtual panels and invite-only events, with a strong emphasis on booked meetings rather than attendance alone.
Its public offer includes a guarantee that at least half of attendees will book a post-event follow-up meeting, alongside claims about low confirmed-guest drop-off and London enterprise reach. That outcome-led positioning makes it worth considering for technology marketers who want a compact event tied to a defined meeting target.
Best for: Enterprise technology companies running London-based, pipeline-focused dinners and roundtables.
Considerations: Validate the guarantee terms, audience definitions, industry fit, attribution process and how the agency handles situations where a target account is relevant but not yet ready for a sales meeting.
Increase Group describes itself as a global event agency specialising in executive engagement. Its offer includes roundtables, executive networking events, breakfast briefings, audience acquisition and virtual formats, often in premium or distinctive locations.
The emphasis on memorable peer-to-peer experiences and a broad portfolio makes Increase Group a useful option where brand experience, executive networking and format flexibility are central to the brief.
Best for: Organisations seeking premium executive experiences, a variety of event formats and global delivery capability.
Considerations: If pipeline is the primary goal, agree in advance how named accounts, sales handover, meetings and opportunity influence will be measured.
Choose CXO & Co if your priority is to get a defined group of senior decision-makers from target accounts into the room and create a clear path from the event to commercial conversations. Its model is particularly suited to high-value B2B sales, where quality of access matters more than volume.
Choose The Ortus Club if you need an established international footprint and a consistent intimate format across multiple business hubs. Choose Kinetic Alliance if bespoke service and a mix of dinner, day-event and virtual formats suit your ABM programme. Choose ConvergeX Connections if you are an enterprise technology brand seeking a meeting-led London activation. Choose Increase Group if premium experience design and broader executive networking formats are the centre of the brief.
Whichever partner you shortlist, ask for a proposal that answers five questions: Who exactly will be in the room? Why will they attend? How will the discussion be kept useful and non-salesy? What happens after the event? How will success be measured at account and opportunity level?
CXO & Co is built around a simple commercial idea: the room should contain people your sales team genuinely wants to know, and the experience should give those people a reason to keep talking afterwards.
The service combines:
That makes CXO & Co a strong option for enterprise technology, professional services and other B2B firms where a small number of high-value relationships can materially affect pipeline.
A successful CXO dinner or roundtable should do more than produce photographs and positive feedback. It should deepen relationships with strategically important accounts, reveal what senior buyers care about and create credible next steps for sales.
If that is the outcome you need, speak to CXO & Co about your audience, target accounts and event objective. We will recommend the right format—from an intimate executive dinner to a larger thought leadership summit—and show you how the event can support your enterprise pipeline.
Discuss your target accounts, audience and commercial goals with CXO & Co.
A specialist agency can handle event strategy, audience definition, delegate acquisition, venue and hospitality, agenda design, facilitation, on-the-day delivery and post-event follow-up. The best partner connects all of those elements to a clear B2B objective.
Pricing varies according to guest seniority, recruitment difficulty, venue, location, format, production and post-event support. Compare proposals on the quality of the target audience and commercial scope, not only the per-head hospitality cost.
Most executive dinners work best as intimate conversations. A group of roughly 8–15 guests is common because it allows every attendee to contribute while still creating a useful range of perspectives.
A minimum attendance commitment can reduce risk, but the definition of a qualified attendee matters more than the headline number. Agree seniority, function, company profile, named-account criteria, substitutions and exclusions in writing.
Track target-account attendance, engagement quality, follow-up meetings, opportunities influenced, relationship progression and revenue over an appropriate enterprise sales cycle. Attendance is an input, not the final outcome.
