Most agency owners don’t have an accountability problem with their team. They have an accountability problem with themselves. There’s nobody in the building senior enough, or distant enough, to ask why the things that matter most never get done.
This post covers what an agency NXD actually is, what the role does day to day, the characteristics that separate a good non-executive director from an expensive sounding board, what I learned from working with six of them over fifteen years running my own agency, and the three questions to ask yourself before you appoint one.
What is an agency NXD?
An agency NXD – non-executive director, non-exec, NED, the terminology varies – is an experienced person who sits on your board without being involved in the day-to-day running of the business. They don’t manage clients. They don’t lead the team. Their job is to support, challenge and hold the directors to account for the growth and governance of the agency.
The role didn’t originate in our sector. NXDs have long been standard in larger companies, and especially in PLCs, where having independent directors overseeing the executive team is often a regulatory requirement. Public shareholders want someone scrutinising management who isn’t management. That principle has steadily filtered down into smaller, owner-led businesses – including independent agencies.
The profile has shifted too. NXDs were once almost exclusively retired or semi-retired executives trading on a long career. Increasingly they’re younger, still active – running their own business, holding an executive role elsewhere, or operating a portfolio of non-exec positions across several companies.
For an agency, the appeal is straightforward. You get senior experience and outside perspective without carrying the cost of another full-time director. A good agency NXD acts as a sounding board for the leadership, a source of challenge for decisions that would otherwise go unquestioned, and – where there are minority shareholders – a degree of reassurance that someone independent is watching the executives’ work.
The distinction worth holding onto is this: an agency NXD is not a consultant you hire to fix a problem and leave. They’re a recurring presence at board level, committed to the long-term success of the business, even though they can’t give it their full-time attention.
“An agency NXD doesn’t know why the important thing didn’t get done – and that’s precisely the point. They raise the standard simply by being in the room.”
What an agency NXD actually does
The core function of an agency NXD is to hold the executive team accountable for delivering against the agency’s objectives. Everything else flows from that.
In practice, the role concentrates on two areas: governance and growth. Governance matters in any business – it’s the discipline of running things properly, managing risk, and keeping the company on the right side of its obligations. But in most independent agencies, governance is rarely the burning issue. Growth is. So a good agency NXD spends most of their energy there: pressure-testing the strategy, questioning the plan, and making sure the leadership is moving the business forward rather than just running it.
That outside presence changes the dynamics of a board meeting more than people expect. Running an agency can be exhilarating, fulfilling, frustrating and exhausting – sometimes all in a single afternoon. It’s also genuinely lonely at the top, even when you’re not the sole director. You’re constantly balancing the demands of clients against the needs of your people, and there often feels like nobody you can turn to for genuinely impartial counsel.
The accountability piece is subtle but powerful. When it’s just the founding directors in a board meeting, it’s hard to hold each other’s feet to the fire. If a key objective slipped, you usually already know why – because the same client crisis or cash-flow scramble landed on your desk too. You’re forgiving because you’re in the same boat.
An NXD isn’t in that boat. They weren’t there for the firefighting and they’re not invested in the excuses. That single shift – knowing an external person will ask the question – tends to make everyone raise their game between meetings, not just during them.
The characteristics of a good agency NXD
NXDs are chosen for their personal qualities, their experience and their specialist knowledge. Wisdom alone isn’t enough – they also need to be current, familiar with where the industry and the wider business world are heading, not just where they’ve been.
The traits that matter most:
- Independence. They need a strong, trusting relationship with the executive team while keeping enough distance to retain a helicopter view. The moment an NXD gets too close to the business, they lose the ability to see the bigger picture – which is usually the very thing you appointed them for.
- Challenging but supportive. They have to probe hard without creating conflict. The best ones ask the uncomfortable questions diplomatically, then offer genuine support on the difficult issues. Mutual trust is what makes that possible.
- Courage and integrity. An agency NXD must have the principles to say when something looks wrong or risky, and the courage to disagree with the people paying them. A non-exec who only tells you what you want to hear is worse than no NXD at all.
- Communication and listening. They should be able to explain complex ideas clearly without being dictatorial, command respect in the room, and – crucially – listen and absorb as much as they speak.
Beyond temperament, they need to get up to speed fast. Whether or not they come from the agency world, a good NXD quickly grasps your services, your culture, your team and your clients. And breadth helps. Agency leaders now juggle more operational territory than ever – reputation, ethics, risk, technology, AI, people. An NXD with real range can frame discussions across those areas rather than only the ones they happen to know.
What I learned from six agency NXDs
Over the fifteen years I spent running my agency, six different people served as our agency NXD. Some had deep agency experience; others had very little. That mix was deliberate – we wanted a range of perspectives, including client-side thinking and lessons from comparable businesses in other sectors entirely.
Looking back, the ones with agency experience were more effective. They hit the ground running and needed far less context around the problems we were wrestling with. That doesn’t mean industry experience is essential – the outside view from other sectors was valuable in its own right – but it does mean you should be honest about how much hand-holding you’re prepared to do before the relationship starts paying off.
We always worked with one NXD at a time. In hindsight, I think we’d have grown faster with two. More perspective, more challenge, more accountability. But that’s a luxury – plenty of agencies can’t justify investing in one non-exec, let alone several, and you have to be realistic about what stage you’re at.
The thing I valued most wasn’t the advice. It was personal growth, and it came from an unexpected direction. Leading an agency leaves little room to develop yourself – you’re forever firefighting and switching between clients and staff. You can also get too comfortable with your co-founders. Familiarity makes it harder, not easier, to challenge each other over time.
Having an external person in the room broke that pattern. We raised our game because someone we respected, and wanted to impress, was watching. The real return on our agency NXDs wasn’t their network or even their wisdom – it was the accountability they built into the business. That, more than anything, is what moved us from Standstill towards STANDOUT.
The Bottom Line
If you’re an agency owner weighing this up, start with three questions: Why do I want an agency NXD? What specifically do I want them to bring? And what sort of person do I want to work with? Here’s the honest answer to the first one: nobody needs an agency NXD. What you need is help with the problems you’re facing. The non-exec is just one possible route to that help, and it’s worth being clear-eyed about whether it’s the right one.
One word of caution. A lot of owners eye up an agency NXD as a new business channel – someone with a fat contact book who’ll funnel client opportunities your way. In theory, the network is real. In practice, I’ve almost never seen it bear fruit. If lead generation is your primary reason for appointing one, think again.
What an agency NXD will reliably give you is a different set of experiences – and the catch is that you have to define what value you’re after, and how both of you will measure whether they’re delivering it. As with any hire, you’re not buying the role, you’re buying the value a particular person brings. Chemistry is non-negotiable: you need to genuinely connect with your agency NXD and enjoy working with them, every bit as much as the rest of your senior team. Get that right, and a good non-exec becomes one of the most quietly transformative appointments an agency can make.
