A $5,000 monthly retainer on $20,000 of ad spend is a 25% tax on your media budget. On $200,000 of spend it's 2.5%. Same agency, same scope of work, completely different math. Most shortlists skip that arithmetic and open with logos.
DTC brands hire a media buying agency so someone else runs paid acquisition while the founder runs the business. The catch is that the agencies with the loudest marketing are built for brands spending $200K a month, and the brands doing the searching are usually spending a tenth of that. Picking the wrong size of partner costs more than picking the wrong specialism.
So this list is sorted by the monthly ad spend each agency is built for, from $10K through $500K+. Underneath it you'll find the fee math, four questions that expose a weak buyer on a sales call, and an honest case for not hiring anyone yet.
TL;DR
- Sort media buying agencies by the ad spend they're built for before you sort by specialism.
- A retainer under 10% of monthly ad spend is the rough line where an agency pays for itself.
- Creative volume, not bidding, is what decides how far a DTC account scales in 2026.
- Ask for a live account walkthrough. Decks hide everything a walkthrough exposes.
What is a media buying agency?
A media buying agency plans, buys and optimises paid advertising for a brand across platforms like Meta, Google, TikTok and YouTube. The work covers budget allocation, bid strategy, audience setup, creative testing and measurement. For DTC brands, most strong agencies now produce ad creative in-house as well.
How much does a media buying agency cost?
Most DTC media buying agencies charge $2,000 to $20,000 per month, or 10% to 20% of managed ad spend. Boutique shops start near $2,000. Enterprise agencies running Meta, Google, Amazon and connected TV in parallel usually start at $40,000 per month.
What ad spend do you need before hiring a media buying agency?
Around $10,000 a month in ad spend is the practical floor. Below that, a $2,000 retainer eats 20% of the budget and the account rarely generates enough conversion data for the agency to optimise against. Under $10,000, a strong freelancer usually returns more.
What a media buying agency manages in 2026
The job changed. Platform algorithms took over most of the targeting and bidding work that media buyers used to do by hand, so the lever that's left is creative supply. Meta's Andromeda retrieval engine sifts tens of millions of eligible ads down to a shortlist for every single impression, and it groups near-identical creatives together. Ship five ads that share a concept and you get the retrieval weight of roughly one.
That single change reorganised what a good agency does with your money. Budget pacing and bid strategy are table stakes now. What separates buyers is how many distinct concepts they can put into the auction each month, how fast account signals turn into the next round of creative, and whether anyone is checking platform-reported ROAS against the bank account.
The second half of the job is measurement. Meta and Google will both claim the same purchase, so a buyer optimising to in-platform ROAS is optimising to a number that overstates their own contribution. The agencies worth paying manage to blended MER and contribution margin instead, which means they need your unit economics before they can do the job properly.
Four questions that expose a weak media buyer
Sales calls are designed to hide this. Case study decks show the winning quarter and skip the three before it. These four questions are hard to answer with a slide.
1. Walk me through the last three optimisation decisions you made on a comparable account. A real buyer names the campaign, the data they looked at, what they changed and what happened next. A weak one describes a process.
2. How many net-new creative concepts will you put live in month one, and who makes them? If the answer is under ten, or the creative sits with a separate vendor, your account will plateau the moment the first winner fatigues.
3. What did you get wrong on your last account, and how did you catch it? Everyone burns budget somewhere. The buyers worth hiring can tell you exactly where, because they were watching closely enough to notice.
4. Who owns the ad account, the pixel and the creative files? The correct answer is you. Agencies that run media inside their own business manager hold your audience history hostage. We cover more of these in our guide to marketing agency red flags.
"A $2,500 retainer is 25% of a $10,000 ad budget and 2.5% of a $100,000 one. The fee is identical. The bar the agency has to clear is not." — Top Growth Marketing
The shortlist, sorted by the spend each agency is built for
Eight agencies, ordered by the monthly ad spend they're structured to serve rather than by any claim about who is best. An agency built for $250K a month will happily take your $15K and staff it with whoever is free. Match the size first, then the specialism.
1. Top Growth Marketing
Built for: $10K to $100K a month in ad spend.
We're a Los Angeles DTC agency founded in 2011 that has run over $300M in profitable ad spend for 200+ eCommerce brands. Meta, Google, TikTok and Klaviyo email sit with one team, so the same people reading the ad account also write the flows that monetise the traffic it buys. Retainers run $2,000 to $10,000 a month with creative and attribution included, month to month, with a first-month money-back guarantee. We're a Klaviyo Master Partner, Meta Business Partner, Google Partner and Shopify Plus Partner.
Skip us if: you're spending above $250K a month and need Amazon and connected TV run in-house, or you want a locked annual contract.
2. Hawke Media
Built for: $15K to $80K a month, and brands that hate contracts.
Hawke sells media buying à la carte with no long-term lock-in, which is unusual and useful for a brand that wants to test an agency relationship before committing. Broad service menu across paid social, paid search and Amazon, plus fractional CMO work.
Skip them if: you want a small senior team that knows your P&L. The modular model means breadth rather than depth on any one channel.
3. Y'all
Built for: $50K+ a month, health, wellness and CPG.
A boutique performance creative shop where the media buyers and the creative team are the same people, so account signals turn into new concepts inside a week instead of waiting on a vendor handoff. Creative output is the whole pitch, and for a brand whose bottleneck is concept volume that's the right pitch.
Skip them if: you need Amazon media buying, or your spend is under $20K a month.
4. Common Thread Collective
Built for: $50K+ a month, and finance-literate operators.
CTC wrote much of the public DTC vocabulary around contribution margin and forecasting, and the reporting reflects it. If your CFO sits in the agency review, this is the roster where that conversation goes well.
Skip them if: your COGS and margin data aren't clean yet. You'll spend the first two months building inputs before the model earns its keep.
5. New Engen
Built for: $75K+ a month, consumer brands.
New Engen runs media and performance creative as a single system rather than two workstreams, with enough production capacity to keep a scaling Meta account fed. Solid retail media bench too, which matters once wholesale enters the mix.
Skip them if: you want a founder-adjacent boutique relationship or you're under $50K a month.
6. Darkroom
Built for: $150K+ a month, beauty, wellness and CPG.
Acquisition, retention, Amazon and TikTok Shop under one roof, which gives the buying team a real view of LTV when they set budgets. Strong fit for a mid-market brand that has outgrown single-channel thinking.
Skip them if: you want pure acquisition and already have retention handled internally.
7. Wpromote
Built for: $200K+ a month, challenger brands.
Incrementality testing and media mix modelling are core rather than an upsell, and the in-house measurement stack ties pacing decisions to revenue forecasts instead of platform dashboards. That capability usually costs an in-house analytics hire to replicate.
Skip them if: you're under $100K a month. Engagement minimums make the maths hard to justify.
8. Tinuiti
Built for: $200K+ a month, multi-channel and marketplace-heavy.
One of the largest independent performance agencies in the US, with unusually mature Amazon and connected TV practices. Channel specialists get staffed in parallel rather than one generalist covering everything, which is what a brand running four platforms at scale needs.
Skip them if: you're Meta-first with no marketplace plans, or you want the senior team from the pitch to stay on the account.
How much does a media buying agency cost?
Retainers cluster in three bands. Boutique shops run $2,000 to $10,000 a month. Mid-market agencies charge $10,000 to $40,000 or 10% to 20% of managed spend. Enterprise agencies running cross-channel programmes start around $40,000 plus media.
The headline number matters less than the ratio. Divide the retainer by your monthly ad spend and you get the real cost of the relationship. At $10K spend, a $2,500 retainer is a 25% overhead the agency has to earn back before you're even. At $100K spend, that same fee is 2.5% and almost any competent buyer clears it.
Roughly 10% is the line. Below it, the agency has room to pay for itself through better allocation alone. Above it, they need to lift performance materially just to break even, and that's a much harder promise to keep. Run your own numbers against our 2026 DTC benchmarks before you sign anything.
One more cost people forget: the ramp. Expect 30 to 60 days of testing before an agency produces stable performance, and budget for the fact that you're paying full freight during it. What happens in the first 90 days covers that period in detail.

When hiring a media buying agency is the wrong call
Three situations where the honest answer is to wait. Under roughly $10K a month in spend, the retainer overhead is brutal and the account generates too few conversions for anyone to optimise against. A senior freelancer at $1,500 a month gets you further.
If your margins can't survive current CPAs, an agency won't fix that. Media buying makes a working unit economic model bigger. It can't make a broken one work, and the fastest way to find out which you have is to model contribution margin per order before you take a single sales call.
And if you already employ a strong in-house buyer, what you probably need is creative supply rather than another strategist. We broke that trade-off down in in-house marketer or agency. Paying an agency to duplicate a role you've already filled is the most common $60,000 mistake in DTC.
Where to start
Match the agency to your spend band before you weigh anything else. Then check the retainer as a percentage of media budget and treat 10% as the line where the arithmetic starts working against you. Whoever survives both filters should walk you through a live account before you sign, because that is the one thing a deck can't fake.
If you're a DTC brand spending $10K to $100K a month and you want a second opinion on your current setup, we'll audit the account and tell you whether you need an agency at all. Book a growth strategy call and we'll go through it with you. If you're still working out whether the timing is right, start with what a media buying agency does.
| ✅ Do | ❌ Don't |
|---|---|
| Shortlist agencies by the ad spend band they're built for | Hire the agency with the best case studies regardless of your budget |
| Divide the retainer by monthly ad spend and judge the ratio | Compare headline retainers between agencies of different sizes |
| Ask for a live walkthrough of a comparable account | Accept a case study deck as proof the team can run your account |
| Keep the ad account, pixel and creative files in your own name | Let the agency run media inside their business manager |
| Judge month one on creative volume and testing structure | Judge month one on ROAS while the account is still learning |
The TGM Take
Most of these lists rank agencies as though quality were a single scale and the best shop is the best shop for everyone. The market doesn't work that way. The variable that predicts whether an agency relationship succeeds is whether your account is big enough to matter to them and small enough that they staff it with people who care.
Across $300M+ in managed spend, the accounts we inherit almost always arrive with the same two problems, and bidding is neither of them. Overlapping audiences bid against each other in the same auction, and a creative library where most of the “new” ads are one concept with a different headline. Both are structural. Both get fixed in weeks, not quarters.
So the consensus advice to hire on specialism is backwards for anyone under $100K a month. Hire on fit and attention first. A mid-tier agency that treats you as a top-five account will beat a famous one that treats you as a rounding error, every time.

Hire a media buying agency if…
You're spending $10,000 a month or more on ads, your contribution margin per order is positive, and creative production is the thing capping your growth. At that point an agency's fee is a single-digit share of media budget and the creative engine is worth more than the retainer costs.
Skip the agency if…
You're under $10,000 a month in spend, your unit economics don't yet clear CAC, or you already employ a capable in-house buyer. In all three cases a senior freelancer plus a creative producer gets you further for less, and you can revisit the agency question once spend justifies it.
Frequently Asked Questions
What is the difference between a media buying agency and a performance marketing agency?
Media buying agencies historically managed paid spend as a standalone function. Performance marketing agencies bundle buying with creative production, measurement and often retention. In DTC the two have largely merged, because creative volume now drives media performance and splitting them across vendors slows iteration down.
How long before a new media buying agency shows results?
Expect 30 to 60 days of structured testing while the agency learns what your audience responds to, then meaningful performance around month two or three. Brands with a clean creative library and working conversion tracking get there faster. Anyone promising a turnaround in week one is selling.
Should the same agency handle media buying and creative?
For most DTC brands, yes. When the team reading account performance also produces the next round of ads, the feedback loop runs in days instead of weeks. Splitting them works if your creative partner is exceptional, but you pay for it in iteration speed.
How many new ad creatives does a DTC brand need each month?
Our working target across DTC accounts is 10 to 20 distinct concepts a month at $20,000 in Meta spend, scaling toward 30+ above $200,000, with several variants under each concept. Variants of the same idea don't count for much, since the platform treats near-identical ads as a single entity.
Can Advantage+ and Performance Max replace a media buying agency?
Not on their own. Both automate bidding and placement, but they still run on inputs a human controls: creative supply, account structure, budget pacing against margin, and the judgement calls when platform numbers disagree with your P&L. Automation moved agency value toward creative and measurement rather than removing it.
