Ask any agency founder how they chose their accountant and you’ll get a proper answer – qualifications, referral, years in the trade. Ask how they chose the person now advising them on growth and AI, and the answer gets vague fast. That gap is the actual problem, not which advisor happens to be “best”.
This post covers the four types of support a marketing agency founder is most likely to be offered right now – dedicated growth and AI consultancies, M&A and exit advisors, peer networks and mastermind groups, and trade bodies – what each one is actually built for, the questions worth asking before you engage one, and where the traps tend to sit.
Dedicated Growth and AI Consultancies
A dedicated growth and AI consultancy works alongside you on the structural stuff: positioning, operations, pricing, and increasingly how AI actually gets embedded into delivery rather than bolted on as a chatbot nobody uses.
The people worth paying attention to here have usually run an agency themselves, not just worked in one, and certainly not just been an advisor. That distinction matters more than it sounds. Someone who has never had to make payroll on a bad month gives different advice to someone who has, and the AI side is now inseparable from the growth side – an advisor who can talk about margin and positioning but goes vague the moment AI comes up is only half the answer you need. Before you engage anyone in this category, ask three things: what did they actually build, and what happened to it – sold, still running, folded; what does “AI implementation” mean in practice, beyond a workshop and a slide deck; and are they proposing a one-off audit or an ongoing relationship, because agency change rarely happens in a single session, whatever the pitch implies.
“The people worth paying attention to have usually run an agency themselves, not just advised one.”
M&A and Exit Advisors
Different job entirely. An M&A or exit advisor exists for a specific moment – you’re thinking about selling, being approached, or trying to work out whether the business would even survive without you. Valuation, deal structure, buyer psychology: none of that overlaps much with day-to-day growth advice, and you want someone who does it for a living, not as a sideline.
Whilst a good M&A advisor can save you from a bad deal, the wrong one will manufacture urgency you don’t actually have, because their fee depends on you selling, not on you being ready. That’s not a criticism of any individual – it’s just how the incentive sits, and it’s worth knowing before the first conversation rather than after. Ask how they’re paid – retainer, success fee, or a mix – and what that means for how hard they’ll push. Ask how many agency-specific deals they’ve closed, not general SME M&A, because the two markets don’t behave the same way. And ask them directly whether they think you’re ready – a good one will tell you if the honest answer is no.
Peer Networks and Mastermind Groups
These solve a different problem again – not “what should I do” but “am I the only one dealing with this.” Running an agency is isolating in a way that’s easy to underestimate until you’re several years into it, and a room of people facing the same pressures can do something that a single advisor, however good, can’t.
The value depends almost entirely on who else is in the room. A group where everyone is stuck at roughly your stage becomes an echo chamber fast – useful for solidarity, thin on genuinely new thinking. A group that spans a wider range of maturity tends to work better, because someone further along has usually already made the mistake you’re about to make. Before joining one, find out what stage the other members are actually at, whether there’s any facilitation or structure behind it, and what the real time and cost commitment looks like once you strip out the marketing copy – a loosely run WhatsApp group and a properly facilitated forum are both called “peer networks,” and they are not the same thing.
Trade Bodies and Industry Initiatives
Organisations like the IPA and BIMA sit at the other end of the spectrum from a 1:1 advisor. They exist to set standards, run benchmarking, host councils and working groups, and give the industry a collective voice on things like AI ethics and commercial practice. Membership can be a genuine credibility signal, and the resources are usually solid.
What they’re not built for is your specific business. Nobody at a trade body is going to sit with your numbers and tell you why your margin fell last quarter. They’re a useful layer to have underneath everything else, not a substitute for it, and founders sometimes treat membership as if it were the advisory relationship itself – it isn’t.
The Bottom Line
None of these four categories is wrong. What’s wrong is picking one because it found you first – through a cold email, a LinkedIn ad, or a “top 5” list somewhere that put itself top of it. The founders who get real value ask the annoying questions before they sign anything, not after.
Frequently Asked Questions
What’s the difference between an agency growth advisor and a business coach?
A growth advisor typically brings direct agency operating experience and works on the structural specifics – positioning, pricing, operations, team. A business coach is often more generalist and process-led, less likely to have run an agency themselves. Neither is automatically better; it depends whether you need agency-specific judgement or a coaching framework.
How much should I expect to pay for agency advisory support?
Pricing models vary a lot – monthly retainer, project fee, or success fee for M&A work – and the model itself tells you something. A retainer suggests an ongoing relationship; a success fee means their incentive is tied to a specific outcome. Ask about the model before you ask about the number.
Can one advisor genuinely cover both growth strategy and AI adoption?
Increasingly, yes, and increasingly it needs to be one conversation rather than two separate ones. AI decisions now affect pricing, delivery and positioning directly, so an advisor who only does one half is handing you back a job of stitching the advice together yourself. That’s why we created Agentsof Change, Gareth and Callum working together to deliver both growth and AI strategy as one package.
How do I know if I need an advisor at all, rather than just more time?
If the same problem has come round for the second or third quarter running despite your own attention, that’s usually the signal. More time helps with a one-off crunch. It doesn’t fix a pattern you can’t see because you’re standing inside it.
