How to Fill an Executive Roundtable

To fill an executive roundtable of 12 seats, plan backwards from shows: on mid-band assumptions you need about 188 personal invitations, 19 acceptances and 15 confirmations to seat 12. Small free events of 10 to 49 attendees lose a median of about 37% of expected attendees (PheedLoop), so confirm 15 for 12 and reconfirm through executive assistants in the final week.

• The metric: seated executives = invitations x accept rate x confirm rate x show rate.
• The asset: an invite-to-seat funnel table with low, mid and high bands, a second-wave threshold table and an executive-assistant confirmation cadence.
• The benchmark: PheedLoop’s Event Data Lab Report #05 puts the median no-show at about 37% for small free events (10 to 49 attendees).
• The rule: hold acceptances at about 1.5 times your seat target by two weeks out, or open a second invitation wave.

Rules of thumb

• On mid-band assumptions, every seat needs about 16 invitations (188 / 12).
• Confirm about 1.25 times the seats you want filled: 15 confirmed at an 80% show rate seats 12.
• At PheedLoop’s 37% small-free-event no-show median, 19 confirmations are needed to seat 12 (19 x 63%).
• PheedLoop advises small free events to plan for up to 40% no-shows; a free roundtable sits in that bucket.
• US anti-spam law makes no exception for business-to-business email, and opt-outs must be honoured within 10 business days (FTC CAN-SPAM guide).

How do I fill an executive roundtable?

An executive roundtable fills when a credible host personally invites a tightly defined peer group to discuss one specific question, then confirms every seat through the executive and their assistant.

A roundtable is not a small conference. The product is the other people in the room, so an executive decides on three things: who else is coming, who is hosting, and whether the question is worth two hours. A generic “Join our CXO roundtable” email answers none of them. The method below works in order:

1. Fix the seat target (this page uses 12) and work out invitations from it.
2. Write the invitation around the question and the peer mix, signed by a named host.
3. Track acceptances against the threshold and open a second wave early if you are short.
4. Confirm through the assistant, not just the executive, in the final two weeks.

Attendance at events of every size, and the general three-touch reconfirmation method, is covered on our event no-show rate page. This page is about the invitation maths and the senior-attendee version of confirmation.

Frequently asked questions

How many people should I invite to an executive roundtable?

On this page’s mid-band assumptions, about 188 personal invitations to seat 12: a 10% accept rate gives 19 acceptances, 80% stay confirmed (15), and 80% of those show (12). A warm list may need about 74; a cold one about 544.

What is a good size for an executive roundtable?

This page plans for 12, within a 12 to 15 seat table: small enough for everyone to speak in a two-hour session. Plan confirmations at about 1.25 times the seat target rather than adding chairs.

What no-show rate should I expect at a free executive roundtable?

Plan conservatively. PheedLoop’s Event Data Lab Report #05 found a median no-show of about 37% for small free events of 10 to 49 attendees and advises planning for up to 40%. Executive roundtables are a subset of that bucket, so treat the figure as a ceiling to beat with confirmation, not a target.

Should I charge executives to attend a roundtable?

A fee lowers no-shows but changes who says yes. PheedLoop’s small paid events had a median no-show of about 17% against about 37% for small free ones, so charging senior guests trades acceptances for show rate; many hosts fund the seats themselves or with a sponsor instead.

When should I send roundtable invitations?

Early enough that acceptances can be checked against the 1.5x threshold two weeks out with time for a second wave, and early enough to land before senior diaries fill.

How many invitations an executive roundtable needs

An executive roundtable needs about 188 personal invitations to seat 12 on mid-band assumptions, and from 74 to 544 across the bands below.

No credible public benchmark exists for acceptance rates on invite-only executive events; the rates below are labelled assumptions to replace with your own history. The one sourced anchor is the low-band show rate: PheedLoop’s analysis of 1,070+ events found a median no-show of about 37% for small free events of 10 to 49 attendees, measured as the share of expected attendees who did not check in (PheedLoop).

Read the table from the bottom up: the seat target fixes everything above it. The gap between 74 and 544 invitations is the difference between a warm list (past attendees, clients, a co-host’s network) and a cold one. If your named list is shorter than the invitations your band needs, the event is short before the first email goes out.

When to open a second wave of roundtable invitations

A second wave of roundtable invitations should go out when acceptances two weeks before the event are below about 1.5 times the seat target.

The ratio comes from the funnel table: in the mid band, 19 acceptances seat 12, about 1.6 acceptances per seat; the high band needs 1.25 and the low band 2.25. The threshold table turns that into a decision.

The peer-nomination ask is the cheapest second wave: an executive who has said yes is the most credible inviter you have, and their nominee arrives pre-qualified by seniority.

What makes a senior executive accept a roundtable invitation

A senior executive accepts a roundtable invitation that names one specific question, a credible host and the other guests’ seniority, sent by a person.

• One question, not a theme. “How are CFOs funding AI pilots without new headcount?” beats “The future of finance”.
• The peer mix. State the room by role and sector (“12 CFOs from mid-market manufacturing and logistics”), with names only where guests have agreed.
• A named host who signs the invitation and is a peer, an analyst or a respected practitioner, not a sales rep.
• A confidentiality rule stated up front: what is said is not attributed, and there is no pitch from the floor.
• The time cost. Date, start, finish and format in one line; senior diaries fill early.
• An easy yes. A reply-to-accept email or a two-option calendar link, plus an offer to send the hold to their assistant.

Invitations are commercial email in most markets even when they are B2B. In the US, the FTC’s CAN-SPAM guide says the law makes no exception for business-to-business email (FTC); in Australia, ACMA says commercial messages under the Spam Act 2003 need consent, sender identification and a way to unsubscribe (ACMA). General information only, not legal advice.

The confirmation cadence that keeps executives in their seats

The executive roundtable confirmation cadence has five touches, and the call to the executive assistant in the final week is the one that protects the seat.

Two rules make the cadence work at this level. First, agree a substitution policy in advance: a same-seniority colleague may take a released seat, which keeps the room level. Second, never overfill the table to compensate; an extra chair at a 12-seat roundtable changes the conversation more than an empty one. After the session, the follow-up sequence that turns guests into pipeline is set out in how to turn event attendees into clients.

Who to invite and where the names come from

The roundtable invitation list comes from warm sources first, because warm names are the route to the high band’s 74 invitations for 12 seats rather than the low band’s 544.

• Past guests and clients who fit the seniority rule: the highest accept rate you will see.
• A co-host’s network: a partner firm, sponsor or association that invites its own executives under its name.
• Accepted guests’ nominations, as in the second-wave rule.
• Dormant contacts in your CRM at the right level, re-approached with the specific question; the method is on our database reactivation page.
• Cold research last, by role, sector and company size, with each invitation written personally.

Hold every guest to the same seniority line. One junior attendee who “will take notes” lowers the value of the seat for everyone else, and senior guests notice.

What filling a roundtable yourself costs in time

Filling a mid-band executive roundtable in-house takes about 30 hours of organiser time, on the task estimates below.

The time is not the hard part; consistency is. The assistant call a week out and the follow-up to non-responders are the tasks that slip when the organiser is also running the event. Teams that hand the calling to someone else often use an appointment setting service for the confirmation and post-event booking steps.
