A founder asked me last week how to vet an agency she was about to hire. We spent thirty minutes on Zoom going through her shortlist, and most of what I told her came down to five patterns I’ve watched repeat across agencies, across categories, across price points.
So I figured I’d write them down. Not as a takedown of the industry I run a business inside. As the version I’d give to a friend who’s about to spend real money and wants to spend it well.
The Quick Version: Five patterns to watch for: a free discovery call structured like a sales pitch, no system underneath the work, promises that ignore the real timeline of brand work, a track record of churning clients, and an agency that won’t tell you not to hire them. None of these is individually fatal. All of them together is.
This is for the founder about to wire a deposit. The agency you’re considering probably isn’t bad. The patterns below are the ones that decide whether the engagement compounds or quietly drifts.
Red Flag #1: The "Free Discovery Call" That’s Really a Sales Pitch
You’ll spot this in the first conversation. You booked a discovery call expecting a working session. You got a thirty-minute deck about the agency, with a soft close at the end and a proposal in your inbox the next morning.
That’s not discovery. That’s sales theater. And the structure tells you something important about how the agency thinks about the work.
The version I trust is the inverse: a paid diagnostic. We run one called a Brand Jump (it’s $1,500, and it credits forward into any larger engagement). The reason it’s paid isn’t a money grab. Real diagnostic work takes time, asks hard questions, and produces an output the founder can actually use, with or without us.
You can tell which model an agency runs by asking one question: "What does your intake process look like, and what do I leave with?" Free discovery calls leave you with a proposal. Paid diagnostics leave you with clarity. They’re different products.
If every agency on your shortlist runs a free discovery call, you’re not unusual. That’s the industry norm. But the ones that don’t are usually the ones taking the work seriously enough to charge for the diagnosis.
Red Flag #2: No System Underneath the Work
The second red flag I watch for is structural, and it’s harder to spot. Ask the agency how they actually run an engagement, day to day, and see how specific they get.
What you want to hear:
- A briefing process with a template they actually use
- A content calendar or production pipeline you can see
- An approval flow that doesn’t require six Slack messages to find the latest version
- A quality control layer (often an art director or senior reviewer) sitting between the work and the client
- A way to onboard your team into how they work
What you don’t want to hear: "We just kind of figure it out as we go" or "It’s pretty fluid." That sounds flexible. It usually means the engagement will be reactive, the standard will drift, and the work will quietly degrade as the months stack up.
A VP of Brand and Content I worked alongside described what good operational work looks like inside an engagement as "Systems, not chaos." That’s the bar. You’re not looking for bureaucracy. You’re looking for repeatability. Repeatable processes produce repeatable quality. Chaotic ones produce hero work at the start and a slow drift afterward.
Mediabistro’s recent industry coverage of fractional creative leadership engagements flagged the same failure pattern: engagements break down most often when scope isn’t defined day one, when the senior person isn’t actually in the room, and when the work gets handed off cold to junior staff. The pattern applies to agency engagements just as cleanly.
Red Flag #3: Promises That Ignore the Real Timeline of Brand Work
This one is easy to miss because it sounds like ambition. The agency promises results faster than the work can actually produce them. They’ll have a new brand identity in three weeks. They’ll lift conversion by 30 percent in a quarter. They’ll get you ranking on the first page in two months.
Sometimes those numbers are honest. Often they’re the agency optimizing for the close and assuming you won’t remember the promise in six months.
The version I trust sounds slower and softer. "We think this engagement will start moving the metric you care about somewhere between month two and month four, depending on how much rollout you’re funding alongside the work." Less exciting. More honest. The brand work that actually compounds takes a quarter at minimum to show up in the numbers, and most of the first quarter is rollout and consistency, not new creative.
The agencies promising fast results aren’t necessarily lying. They’re just optimizing for the part of the customer journey that ends at signature. The ones I’d hire are optimizing for the part of the customer journey that ends at renewal.
A useful question to ask: "What does month four look like in this engagement?" If the agency can’t answer concretely, they haven’t thought past the launch. That’s the gap that quietly costs the most.
Red Flag #4: A Pattern of Churning Clients
This one is the hardest to spot from outside, because no agency will volunteer it. But it’s also the one with the most predictive value, so it’s worth digging for.
A few ways to surface it:
Ask for a client they’ve worked with for more than two years. Good agencies have a few of these. Mediocre agencies don’t, and the absence is information.
Ask for a reference from a client who left. Reputable agencies will sometimes share these. The bad-breakup version of the conversation tells you more than the glowing-review version does.
Look at the agency’s case study cadence. Are the case studies all from the same six-month window two years ago, or is there a steady flow of work shipping every quarter? Quiet case study pages tell stories.
Look at the agency’s portfolio for repeat work with the same client. A campaign for Brand X two years ago and another for Brand X this year is a much better signal than a one-and-done.
The honest version of this in our shop: a client we worked with for six years through some of the hardest brand decisions her business ever made. That tenure isn’t easy to fake, and it’s the part of an agency’s track record that says the most about how the engagement actually runs once the launch is over.
Agencies that retain clients have figured out how to compound work. Agencies that churn clients usually haven’t. The question is rarely whether the new work will be good. It’s whether the work will still be good in month nine.
Red Flag #5: They Won’t Tell You Not to Hire Them
This one is my favorite, and it sounds counterintuitive. The agencies I trust most are the ones that occasionally turn away work.
Real reputable shops decline engagements where the fit is wrong: budget that doesn’t support the scope, positioning that needs to be settled before any creative work makes sense, founders who want a vendor relationship instead of a partnership, categories the agency doesn’t serve well. They route those prospects elsewhere or recommend a different kind of help.
If the agency you’re talking to says yes to every conversation, that’s not enthusiasm. It’s incentive alignment. They’re optimizing for the close. Which means they’ll take engagements that are wrong for the work, because every engagement is right for the revenue.
The test: in your first or second conversation, ask the agency "Is there any scenario where you’d tell me not to hire you?" The answer tells you almost everything.
The reputable answer sounds like: "Yes. If your positioning isn’t settled, we’d recommend a paid diagnostic before any creative work. If your budget is below a certain threshold, we’d route you to a self-service tool or a smaller studio. If your category is outside our vertical, we’d refer you out."
The version I’d hesitate on sounds like: "We can make anything work."
A Few Smaller Patterns I Also Watch For
These wouldn’t sink a deal on their own, but they’re yellow flags I’d add up across a conversation:
The senior person pitches and the junior person delivers. Common pattern. The partner you met in the pitch isn’t the person who’ll be on your account in month three. Ask who’ll be in the room day-to-day and meet them before you sign.
Vague case studies. Activities described without outcomes. Process slides without results. Usually means either the results weren’t good or the agency doesn’t measure outcomes. Either is a problem.
Pressure to sign before you’re ready. Discount that expires Friday. A spot in the calendar about to close. Sometimes real. Often a scarcity play. Reputable shops don’t need to push.
Most engagements don’t fail because the agency is bad. They fail because the founder ignored a yellow flag in week one that turned out to be a red flag by month four.
How I’d Make the Decision
If I were hiring an agency for my own business right now, here’s the order I’d run the process in:
- Pay for the diagnostic, with someone you’re already 70 percent decided on. Get a real look at how they think, what questions they ask, and what the deliverable looks like.
- Talk to a current client they’ve worked with for over a year. Listen for whether the work has held up, whether the relationship still feels like a partnership, and whether the agency is the same partner now as in the pitch.
- Read the scope of work line by line, twice. Ask what’s not included. Ask what happens when something goes wrong.
- Notice how the agency responds when you push back. Reputable shops welcome it. Bad fits get defensive.
- Trust the gut read on the people. If the energy is off in the first two conversations, it almost never gets better in the engagement.
The good news is that the agency you eventually hire doesn’t have to be the most prestigious shop on your shortlist. It has to be the one whose system, taste, and incentives line up with what you actually need built. Which is mostly a matching problem, not a ranking problem.
If you want a second set of eyes on a shortlist before you commit, I do that work in fit calls all the time. Happy to dig in if any of this is landing.
