What a Marketing Broker Does, and Why 200,000 Agencies Made the Job Necessary

A marketing broker diagnoses what your business actually needs, then matches you with vetted agencies. Here is how the model works, what it costs, and how to vet anyone you hire.

Promethean Research’s 2026 State of Digital Services reports more than 200,000 digital agencies worldwide, including over 71,000 in North America alone.

Here is a more useful fact. Nobody can agree on the number. Estimates of the US market alone range from roughly 41,000 to 114,000 depending on who is counting and what they count as an agency. Professionals who study this industry can’t draw a line around it.

That is what you are up against when you go looking for help. Not too few options. Too many, with no way to tell them apart.

I have spent seven years inside this problem. I have sat across from more than 1,100 agencies and turned down roughly nine out of ten. What follows is what I have learned about why the market looks like this, and what to do about it if you are the one who has to make the call.

200,000 agencies and no way to compare them

Choice is only useful when you can compare the options. Marketing services fail that test almost completely.

When you buy software, you can trial it. Hiring a full-time marketer, you can check references and run a structured interview against a role you understand. Buying equipment, there are specs.

An agency engagement has none of that. You are buying a promise of future work, delivered by people you have mostly not met, measured by metrics you may not have chosen, over a timeline long enough that by the time you know it isn’t working, you have spent six figures.

So buyers watch for signals:

• The website, which measures a design budget
• The logos, which tell you who signed, not who stayed or who got results
• The pitch, which measures sales skill, a different muscle than execution
• The referral, usually one person’s single experience in a different industry at a different stage

None of those are dishonest. They are just weak. Weak signals at scale produce exactly what the market looks like now: enormous variance in quality, almost no visible difference on the surface, and a steady stream of owners who have concluded that agencies don’t work.

Agencies do work. Badly matched agencies do not. Those are different problems, and the first one takes the blame for the second.

Why searching for an agency doesn’t work

Search used to be a reasonable filter. If a firm ranked for “ecommerce marketing agency,” you could assume they were at least competent.

That broke. Ranking is its own specialty now. The agencies that rank best are frequently the ones best at ranking themselves, which tells you about their SEO team and nothing about whether they can grow your business.

The deeper issue is that search rewards tactic-level queries, and tactic-level queries are usually the wrong starting point.

An executive I spoke with recently put it better than I could. His frustration was not that vendors couldn’t execute. It was that nobody could connect what they were doing to anything he cared about. His question, over and over: how does this move the needle on the bigger business challenges I face, versus the tactical things you keep putting in front of me?

That is the gap in one sentence.

You search for “PPC agency” because someone told you that you need PPC. You get a hundred of them. They all pitch PPC. You hire one, they do PPC competently, and six months later cost per acquisition is down and revenue is flat, and nobody can explain why.

I have watched a business celebrate a 40% drop in cost per click while their actual customer acquisition cost went up. Everyone hit their numbers. The numbers were the wrong ones. That is a diagnosis failure, and it happened before the agency was ever hired.

The real gap: agencies that don’t understand business, businesses that don’t understand marketing

Here is the thesis of this whole piece.

Most bad marketing relationships aren’t caused by lazy agencies or unreasonable clients. They’re caused by a two sided knowledge gap that neither party can close on its own.

A lot of agencies are excellent at a craft and weak at business. They can build a beautiful funnel. They cannot tell you whether your margin structure supports paid acquisition at all, or whether your real constraint is sales capacity, pricing, or retention. They were hired to do a tactic, so they do the tactic and report on the tactic.

Most business owners are excellent at their own business and, reasonably, do not know marketing. They don’t know what a fair price is. They don’t know which specialties are genuinely distinct. They don’t know which questions separate a strong operator from a strong salesperson. So they ask for what they’ve heard of and evaluate on what they can see.

Put those two people in a room. The agency hears a request for a tactic and quotes the tactic. The business hears confidence and buys it. Both sides are acting in good faith, and the engagement will probably still fail, because nobody in the conversation was equipped to question the premise.

This is the part of my work that matters most, and it is the part people are most surprised by. When someone tells me they need SEO, my first question is why. Often the answer traces back to something else entirely: there is no strategy underneath it, or the positioning is wrong, or the site converts so poorly that more traffic would be wasted. Most matchmaking services take the request at face value and hand you a list of SEO firms. I would rather find out what you actually need before anyone gets introduced to anyone.

Most growing companies need three specialists, not one agency

There’s a quiet assumption behind most agency searches: that somewhere out there is one partner who can handle all of it.

That partner mostly doesn’t exist. Companies who go looking for one usually end up with a firm that does one thing well and four things passably, if that.

A real situation, lightly anonymized. 

An ecommerce business came to me with flat growth, convinced they needed a better paid media agency. The actual picture had four separate problems. Organic traffic was strong but concentrated on pages never built to convert. Conversion rate on the highest traffic pages was about half what the category supports. The brand looked a decade older than the customer it was trying to win. And paid spend was efficient because it was being spent on people who were going to buy anyway.

Four disciplines. SEO is not CRO. CRO is not brand and design. Brand is not paid acquisition. 

The skill sets barely overlap.

The economics back this up. Promethean Research found that agencies which narrowed their service offerings averaged 30% net margins in 2025, more than double the 13% industry average. Specialists are more profitable because they are genuinely better at a narrower thing, and that shows up in your results too.

Most growing companies need three to five specialists. That sounds more expensive and usually isn’t, because you stop paying a premium for one firm to learn on your budget in the areas they’re weakest. The harder part is coordination: who owns what, and what happens when two partners disagree. That’s the actual work, and almost nobody plans for it.

The size trap: why the bigger agency often delivers the worse result

This is the advice that costs me the most goodwill, and I keep giving it.

Bigger is frequently worse. Not always. Frequently.

The people who sell aren’t the people who deliver. At a certain size, an agency has a dedicated sales function that’s genuinely excellent at winning business. Then the account moves to delivery, staffed by people three to five years into their careers, because that’s what the economics require.

Process replaces judgment. Scale demands standardization. Your account gets the playbook, and the playbook was built for the median client.

Movement slows. Getting a change approved goes from one conversation to four.

Some scale is bought, not earned. Agencies acquire smaller specialist shops and absorb their logos into the parent brand. The work in that case study may have been done by a team that no longer exists. You’re buying credibility that already walked out the door.

Worth knowing: 87% of North American digital agencies employ fewer than 50 people (Promethean Research, 2026). The small firm is the industry norm, not the risky exception. A thirty person shop whose founder is still in your account reviews will move faster and staff you with the people who built the thing you saw on their site.

The size trap isn’t that big agencies are bad. It’s that size feels like safety, and safety is exactly what it doesn’t buy.

What a marketing agency actually costs

Most owners come to this decision with no reference point at all, which is how people end up paying three times the going rate without knowing it.

Rough public ranges as of 2026: full-service retainers for small and mid-sized businesses commonly run $2,500 to $8,000 per month, while established agencies serving larger accounts run $15,000 to $50,000 per month. Project work sits outside both.

Those ranges are wide for a reason, and the reason matters more than the numbers. Price in this industry correlates weakly with quality and strongly with overhead. A large agency’s rate has to cover a sales team, account managers who don’t touch your work, and office space. A specialist shop’s rate covers the people doing the work. Two firms can quote the same number with completely different amounts of it reaching your account.

What should actually drive your budget:

• Your revenue and margin, not a percentage rule you read somewhere
• Whether you’re funding a test or a known channel. Tests need less money and more patience
• What’s included. Ad spend, tooling, and media are frequently separate from the retainer
• Whether you need strategy or execution. Strategy costs more per hour and less in total

The question worth asking any agency is not “what do you charge,” it’s “what does this number buy, and how much of it reaches my account.”

Agency, in-house, or both

Almost every comparison of this online is published by an agency, and every one concludes you should hire an agency. I don’t execute marketing, so I have no stake in the answer. Here’s the honest version.

Building in-house is expensive and slow. A realistic in-house team runs somewhere between $180,000 and $350,000 a year once you include salary, payroll taxes, benefits, and tooling. More importantly it takes three to six months to hire and another three to six to get productive. If you need results in a quarter, that path doesn’t exist.

Agencies buy speed and breadth. You get a team instead of one generalist, and they start in weeks rather than months. You give up brand immersion and some control, and you’re a client rather than a priority.

For most businesses between $3M and $20M, the answer is both. One in-house person who owns brand voice, context, and the vendor relationship, with specialists executing. That person doesn’t need to be a marketing expert. They need to be good at your business and good at managing partners. This is the structure that works most often in the revenue band I work in, and it’s rarely the one people arrive considering.

The failure mode to avoid is hiring an agency to compensate for having nobody internally who can direct them. Agencies need a counterpart. Without one, even a good partner drifts toward the work that’s easiest to report on.

Marketing broker vs. marketing agency vs. fractional CMO

These three get confused constantly, and the confusion costs money.

The short version: a marketing broker helps you hire the right marketing agency or fractional CMO based on what you actually need. We aren’t an alternative to them. We’re the step before them.

How I vet the agencies I work with

Over seven years I’ve met with more than 1,100 agencies. Roughly one in ten is in my network.

That isn’t a brag, it’s a statement about how aggressive the filtering has to be before it’s worth anything to you. A directory with a 90% acceptance rate hasn’t filtered anything. It has made a longer list.

The gut check, 30 to 45 minutes. Who are you, who do you serve, who do you turn away. I’m listening for whether they can describe the client they’re wrong for. Anyone who serves everyone has never had to choose.

References, focused on what went wrong. Anyone can supply three happy clients. I ask about the engagement that fell apart. What happened, what they’d do differently, whether they refunded anything. How a firm talks about failure tells you more in five minutes than a case study page does in an hour.

A 90 minute deep dive. This is the part buyers never get to. An hour and a half on how the work actually happens: who does it, what the week looks like, how they price, how they handle a client who’s underperforming, where work gets handed to a junior, where the founder stays involved.

Ongoing. Agencies change. People leave. A firm that was excellent two years ago may not be now, and I’d rather know before I introduce you than after.

None of this is automated, and I want to be direct about that, because it’s what separates this from the rest of the market. I don’t use AI to make matches. As far as I’ve been able to find, I’m the only broker who doesn’t. AI is good at matching a stated requirement to a stated capability. It cannot sit in a room and notice that a founder and an agency lead will grate on each other by month three. Personality fit is not a soft consideration. It’s the most common reason good engagements die.

Vetted is the floor. Matched is the point. The question isn’t whether an agency is good, it’s whether they’re right for this specific business, at this size, at this budget, with these people.

What working this way looks like

It starts with distrust. Almost nobody comes to me excited. They come in skeptical, usually because the last engagement went badly.

Diagnosis before sourcing. The first conversation is about your business, not about agencies. Revenue, margins, what’s actually constraining growth, what your team can and can’t handle, what you’ve tried and why it failed. A company that asked me for a paid media agency needed a pricing and positioning conversation first. I told them not to spend the money yet.

Then sourcing against real constraints. Budget range, stage, industry, working style, and whether your account is meaningful to that agency or a rounding error. A firm whose average engagement is three times your budget will be polite and won’t prioritize you.

Introductions with both sides primed. I tell the agency what this business needs and where friction is likely. I tell the business where this partner is weak. Nobody walks in performing.

You choose. You meet the partners and decide. I’m not incentivized to push one over another.

And it continues. If it isn’t working, I want to hear early. Finding a replacement costs you nothing more from me.

The situations that bring companies here

“We got burned by a large agency and we don’t trust anyone now”

Impressive pitch, senior people in the room, then the account is run by someone two years out of school. Reporting looks busy, results are thin. What resolves it is rarely a bigger, safer looking firm. It’s a smaller one where the people who pitched are the people doing the work, with references that hold up under pointed questions.

“We’re growing faster than our internal team can keep up with”

One or two good marketers, underwater. Hiring takes months you don’t have. The temptation is a generalist agency to take everything off their plate. Usually the better move is narrower: specialists for the two functions that are genuinely bottlenecked, with your team keeping context, brand, and customer knowledge.

“We need someone who understands our category and nobody does”

Common in regulated, technical, or operationally unusual businesses. One company I worked with wasn’t facing a marketing problem at all. They were facing a labor shortage that expressed itself as a lead generation problem, and generic agencies kept proposing generic campaigns. The fix is partners with real category depth, or partners honest enough to say they lack it and curious enough to build it with you.

“Our metrics look good but revenue isn’t moving”

Impressions up, engagement up, cost per click down, revenue flat. This is almost always a measurement problem that started as a scoping problem. The engagement was defined in channel metrics instead of business outcomes, so the agency optimized honestly toward the wrong goal.

What the broker model costs, and why it’s built this way

It starts with a complimentary business discovery call. If I can’t help, I’ll say so, and often I’ll tell you what to do instead.

If we work together, there’s a small one-time fee for the broker engagement. After that, a marketing broker earns through a referral fee from the agency, which comes out of the budget that agency would otherwise spend acquiring clients. This isn’t theoretical: RSW/US found that 75% of agencies name referrals as their primary source of new business. That money is already allocated. You’re redirecting it, not adding to it.

Two things about this structure determine whether you can trust the advice.

The upfront fee means both sides have skin in the game. Free introductions get treated as free.

No single partner pays more to be recommended. If one agency could buy preference, every recommendation would be suspect, and the network would be worthless within a year.

You’re paying for curation and judgment, not execution. Whether that’s worth it is a simple comparison: the cost of one twelve-month engagement with the wrong partner, plus the year of growth you didn’t get.

Questions to ask before you hire anyone

Use these whether or not we ever speak. For a deeper look at the selection process, I’ve also put together 12 lessons for picking the right marketing agency based on what I’ve learned from evaluating more than 1,100 firms.

About the work

1. Who specifically works on my account day-to-day, and at what experience level?
2. What percentage of their time is allocated to us?
3. Walk me through your first 90 days. What happens in week one?
4. What do you do when something isn’t working at month four?

About fit 5. What kind of client are you wrong for? 6. What’s your average client’s revenue and budget? 7. Have you worked with a business at our stage in our category?

About results 8. What business outcome will you be accountable for, not what channel metric? 9. Show me an engagement that failed. What changed afterward? 10. Can I speak to a client who left you?

About the contract 11. What’s included, and what triggers additional cost? 12. Who owns the ad accounts, analytics, and creative assets if we leave? 13. What’s the exit clause and notice period?

Question 12 is the one people forget, and it’s the one that hurts most. If the agency owns your ad accounts and historical data, leaving means starting over.

If a firm gets uncomfortable at question 5, 9, or 10, that discomfort is your answer. Good operators like these questions.

What changes when the gap closes

None of this is really about agencies.

The average agency-client relationship lasts under three years, which means most businesses are permanently in some stage of searching, onboarding, or unwinding. That’s the real cost.

When the two sided gap closes, three things change. Growth stops being a roulette wheel, because you stop absorbing ramp-up costs every fourteen months and start compounding. Your category gets real expertise applied to it, and the gap between specialist and generalist outcomes is usually larger than the gap in their fees. And you get your attention back, which is the cost nobody counts: the leadership hours spent managing something you shouldn’t have to be an expert in.

That’s what 200,000 agencies really cost businesses. Not just wasted spend, but years of attention spent looking for signal in a market that doesn’t provide any.

If you’re somewhere in that search now, a conversation costs nothing. Worst case, you leave with better questions.

Frequently asked questions

What is a marketing broker? A marketing broker is a buyer-side advisor who diagnoses a business’s marketing needs and matches it with vetted agencies or specialists. Brokers don’t execute marketing work themselves, which is what allows them to stay neutral about who you hire.

How much does a marketing broker cost? Most engagements start with a complimentary discovery call, followed by a small one-time fee. The broker’s main compensation comes from a referral fee paid by the agency, drawn from budget that agency would otherwise spend on sales and business development.

Is a marketing broker worth it? It’s worth it when you don’t know what you need, have no network of vetted partners, and the cost of hiring wrong is high. 

How is a marketing broker different from a marketing agency? An agency executes marketing work and is paid by you to do it. A broker doesn’t execute anything and is paid by the agency after a match, which means the broker has no reason to sell you a service you don’t need.

Do I need a marketing broker or a fractional CMO? A fractional CMO provides ongoing senior marketing leadership inside your business. A broker helps you decide what you need and who to hire, including whether a fractional CMO is the right answer. The broker engagement is short. The fractional CMO engagement is ongoing.
