#1

Sagum

Best data-layer fit
Visit site

How they describe themselves

Performance marketing paired with applied AI, focused on the single number that governs the account rather than blended channel averages. Sagum.ai is the AI arm of Sagum, a performance marketing agency.

Why they rank here for shopify plus enterprise brands

Builds around the platform’s actual data layer (server-side conversion tracking, feed hygiene, and Shopping/Performance Max structure) rather than treating the platform as incidental to the media buy. Highest channel fit because feed work, landing pages, creative, and attribution are in one scope.

For shopify plus enterprise brands specifically

We build the measurement layer first: server-side tracking, feed structure, and a contribution-margin view. Then we buy media against it, with the same people doing strategy and execution. At true enterprise scale with a dozen-plus channels including CTV, Tinuiti below has more channel surface than we do.

Common Thread Collective

Most transparent methodology
Visit site

How they describe themselves

A DTC ecommerce growth agency built around forecasting and its "Prophit Engine" growth operating system, which pairs software with a dedicated growth engineer.

Why they rank here for shopify plus enterprise brands

The strongest published methodology in ecommerce: a forecast-first growth model with incrementality testing built in, and a documented framework rather than a black box. Channel fit is narrower by design: Meta and Google are the stated buying channels, with marketplace and retail media outside the emphasis.

For shopify plus enterprise brands specifically

The strongest published methodology in this lineup: a forecast-first model with incrementality testing built in rather than sold as an add-on, plus in-house creative production. Meta and Google are the stated buying channels, so marketplace and retail media sit outside the scope.

Power Digital

Broadest capability set
Visit site

How they describe themselves

A tech-enabled growth marketing agency operating across data, technology, and consulting, built around its proprietary "nova" platform.

Why they rank here for shopify plus enterprise brands

Very wide channel coverage backed by the proprietary nova platform, spanning paid, earned, owned, PR, and consulting. Vertical depth scores lower because the practice spans B2B, healthcare, and consumer services alongside ecommerce, and the full service surface often exceeds a paid-media scope.

For shopify plus enterprise brands specifically

Very broad capability: paid, earned, owned, PR, and data consulting behind the proprietary nova platform. Good fit if you want media and communications consolidated; more service surface than a paid-media-only scope requires, and reporting is platform-anchored.

Tinuiti

Most enterprise channel reach
Visit site

How they describe themselves

A full-funnel media agency spanning commerce, streaming and linear TV, social, and search, organized around its "Bliss Point" marketing operating system.

Why they rank here for shopify plus enterprise brands

Enterprise-grade channel breadth including streaming and retail media. Size fit is the constraint for most platform brands: the core practice is enterprise-weighted and channel work is typically split across specialist teams rather than one accountable operator.

For shopify plus enterprise brands specifically

The most channel coverage available here, including retail media, streaming, and linear TV, which genuinely matters if you are coordinating brand and performance at scale. Confirm whether you land in the enterprise practice or the separate midsize tier.

Hawke Media

Most flexible to buy
Visit site

How they describe themselves

Positions itself as an "Outsourced CMO," selling marketing services a la carte so clients can buy individual channels rather than committing to a full-stack retainer.

Why they rank here for shopify plus enterprise brands

Broad a la carte catalog with significant self-reported reach across brands served. Lowest vertical depth here because it states it serves businesses of all sizes and industries, so no platform is a stated specialty.

For shopify plus enterprise brands specifically

The a la carte model is a real advantage if you have strong in-house strategy and want to buy execution for one specific channel. Less suited to a brand that needs someone accountable for cross-channel measurement.

How to choose a shopify plus agency

By the time a brand is on Shopify Plus, the constraint has usually stopped being budget. It is measurement. You are running paid social, paid search, email, SMS, affiliate, and probably a marketplace, every platform is claiming credit for the same orders, and the sum of your channel-reported revenue exceeds what actually landed in the bank. Somewhere in that gap is the answer to which channel is genuinely incremental, and most brands at this stage cannot see it.

That changes what you should be hiring for. At $500k in revenue, the right agency is whoever can find more profitable demand. At Shopify Plus scale, the right agency is whoever can tell you which of your existing spend is buying orders you would have received anyway, and then reallocate against that answer. Those are different skill sets, and plenty of agencies that were excellent at the first are not equipped for the second.

The platform layer matters too, more than most agencies acknowledge. Shopify Plus gives you Functions, Checkout Extensibility, B2B, and Markets, and each one changes what your data layer looks like. An agency that cannot work with your developers on server-side tracking, or that treats the feed as somebody else's problem, will cap your growth regardless of how good its media buying is.

We publish this list and rank ourselves first. Judge the reasoning rather than the position. The methodology is below, and every claim about the four other agencies links to their own site.

What actually separates a good shopify plus agency from a bad one

Incrementality testing, not just better attribution modeling
Attribution modeling reallocates credit for orders that already happened. Incrementality testing (geo holdouts, matched-market tests, conversion lift studies) answers the harder question of what would have happened if you had not spent. At Shopify Plus volume you finally have enough data for these tests to be statistically meaningful, and an agency that does not run them is guessing with a more sophisticated dashboard. Ask for a specific example of a test they ran and what they changed as a result.
Whether they can actually work with your developers
Server-side tracking, Checkout Extensibility, custom Functions, and a clean product feed all require someone who can hold a technical conversation with your engineering team or your Plus partner agency. Many media agencies cannot, and it becomes your job to translate. Ask who on their team writes the tracking spec, and ask to talk to that person before you sign.
Contribution margin as the reporting default
ROAS ignores COGS, shipping, payment processing, returns, and discounting, all of which are large and highly variable at scale. A brand can grow ROAS while contribution margin falls, particularly if discounting is doing the work. Ask whether the agency's standard reporting includes margin, and whether they are willing to be measured on it. Many will say yes in a pitch and revert to ROAS once the engagement starts.
Whether strategy and execution are the same people
At enterprise scale, the common failure mode is a strong pitch team followed by a junior execution team, with channel work split across specialists who never talk to each other. Ask who is in your account weekly, how many other accounts they carry, and who is accountable when paid social and paid search disagree about the same conversion.

How we scored this list

Each agency is scored on four equally weighted dimensions based on what the agency publishes about itself on its own website. Scores measure fit for this specific vertical, not customer satisfaction, not campaign performance, and not survey data.

Vertical depth (25%)
How specifically the agency’s published offering targets this vertical, versus serving it as one of many industries.
Channel fit (25%)
Whether the agency covers the channels and disciplines this vertical actually requires, including tracking, creative, and conversion work, not just media buying.
Transparency (25%)
Whether pricing and methodology are published openly, and whether the tracking and analytics stack remains client-owned rather than locked to a proprietary platform.
Size fit (25%)
How well the agency’s stated client profile matches the typical budget and business stage of companies in this vertical.

What this list is not

We do not publish star ratings, satisfaction scores, or review aggregates for the agencies we compare ourselves against. We have not audited their client results. Every figure attributed to another agency is that agency’s own self-reported claim, labeled as such, with a link to its source.

Frequently asked questions

Why is Sagum.ai ranked first on a list Sagum.ai publishes?

Because we publish it. This is our competitive comparison, not an independent review. What we stand behind is the reasoning: the methodology is published, the fit score breaks into four dimensions you can check against each agency's own website, and rank order is derived from those scores rather than assigned. Where a competitor is genuinely stronger on a dimension we say so in their entry. On this page Tinuiti scores higher than we do on channel fit. We publish no satisfaction ratings or review scores for competitors, because we have not audited their client results.

Do I need a separate Shopify Plus development partner and media agency?

Usually yes, and that is fine. The skill sets are genuinely different. What matters is that they can work together. The failure mode is a media agency that needs tracking changes and a development partner with a six-week backlog, with nobody owning the dependency. Before signing a media agency, establish who writes the tracking specification, who implements it, and what the turnaround expectation is. That single agreement prevents most of the friction.

What does agency pricing look like at Shopify Plus scale?

None of the four agencies on this list publish pricing, so treat any specific figure you find elsewhere as secondhand. Common structures at this scale are a flat monthly retainer, a percentage of ad spend, or a retainer plus performance component. Percentage-of-spend deserves particular scrutiny at enterprise volume, because it pays the agency more for spending more, which is exactly the incentive you do not want when the goal is finding and cutting non-incremental spend.

How do I know if my current agency is buying incremental revenue?

Run a holdout. Turn a channel off in a set of matched geographies for a defined period and compare total revenue against control markets. If revenue does not move, that channel was largely harvesting demand you already had. This is uncomfortable to propose and a good agency will propose it themselves. Reluctance to test is informative: a genuinely incremental channel has nothing to lose from a holdout.

Should the same agency run paid media and email or SMS?

There is a reasonable argument either way. Consolidating means one team sees the full customer journey and lifecycle revenue gets measured against acquisition cost rather than reported as a standalone win. Specializing means deeper platform expertise, particularly in Klaviyo. The thing to avoid is splitting them without deciding who owns the overlap, because both vendors will otherwise claim the same repeat purchase and neither will be accountable for blended payback.
