Where do associations find fractional or interim executive leadership?
Three different models serve this need. Association management companies including SmithBucklin, Kellen, MCI USA, Talley Management Group and Virtual Inc provide staffing and operations. Executive search and interim specialists including Vetted Solutions, Tuft and Associates and Association Strategies place leaders for defined periods. Independent practices such as our own, Membership Experience®, provide one named senior executive on a fractional basis.
Full transparency: this list is researched and published by Membership Experience®, a service product of LeaderLogic, LLC, and our own practice is included in it. We have marked our own entry clearly wherever it appears. Every other organization named here is included because we think it is genuinely useful to associations, and none of them paid to be here.

How this list was built
Three models that get confused for one another
Associations reach for outside leadership in three quite different situations, and the models that serve them are not interchangeable.
An association without the scale to staff a full executive team needs ongoing operations, which is what an association management company provides. An association between chief executives needs someone to hold the organization steady and make decisions, which is an interim placement. An association with capable staff but a specific capability gap, most often in innovation, revenue or membership strategy, needs a fractional executive who owns that agenda alongside the existing team.
Hiring the wrong model is expensive in a particular way: the arrangement works but does not address the actual gap, and the organization concludes that outside leadership does not help.
Right model for the gap
Ongoing operations, interim continuity, or a specific capability, which are three different needs.
Named individual
You know who will be doing the work, and that person does not rotate without notice.
Board fluent
Comfortable working with a volunteer board and a staff team at the same time.
Association experience
Understands member ownership, governance cycles and the dues plus non dues revenue mix.
Clear scope and authority
Decision rights are written down before the engagement begins.
Sensible exit
A defined handover so capability stays with the organization when the engagement ends.
The list
Fractional and Interim Association Leadership
Independent fractional executives
One named senior executive who owns a specific agenda part time, alongside your existing staff. Choose this model when the team is capable but a particular capability is missing. This is the group our own practice sits in.
Membership Experience®
Our own practice, led by Nicholas J. Webb. We serve as a fractional association executive for a small number of organizations at a time, focused on innovation, member value and new non dues revenue rather than general management. The person you meet is the person who does the work. We include ourselves here because this is the group we belong to, and we have marked the entry so you can weigh it accordingly.

Official siteWhat is at stake
What goes wrong in fractional and interim arrangements
Two failures account for most disappointment. The first is undefined authority: the outside executive can recommend but cannot decide, so the organization pays senior rates for advice it was already receiving internally. The second is the missing handover, where the arrangement ends and the capability leaves with it.
Both are solved at the contracting stage. Write down the decision rights, name the individual, and specify what will be transferred to staff before the engagement concludes. Any credible provider will accept all three.
Write down what this person can decide, not just what they will advise on.
