#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 bigcommerce 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 bigcommerce brands specifically

We work in your platform rather than adapting a Shopify playbook, keep multi-storefront and wholesale attribution separate so neither is averaged away, and own feed generation and monitoring directly.

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 bigcommerce 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 bigcommerce brands specifically

The most transparent methodology among the alternatives, with forecasting and incrementality testing built in. Their published client work skews to DTC brands on other platforms, so ask about platform familiarity.

Things to weigh before signing

  • No published pricing or minimum retainer; requires a sales conversation

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 bigcommerce 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 bigcommerce brands specifically

Broad capability with the nova platform behind it and genuine mid-market and enterprise experience, which fits brands using the platform’s multi-storefront and B2B features.

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 bigcommerce 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 bigcommerce brands specifically

Widest channel surface here and strong enterprise credentials, appropriate if your scale justifies coordinating retail media and streaming alongside search and social.

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 bigcommerce 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 bigcommerce brands specifically

A la carte model lets you buy a single channel or project, which can be a practical way to get specific work done without a platform-experience gamble on a full retainer.

How to choose a bigcommerce agency

BigCommerce brands tend to have made a deliberate platform choice, often for no transaction fees, multi-storefront capability, strong native B2B features, or headless flexibility. The downside shows up when you go shopping for marketing help: the app and agency ecosystem is smaller than Shopify’s, and a lot of agencies will quietly propose Shopify-shaped solutions and hope the differences do not matter.

They do matter in a few specific places. Tracking implementation, feed generation, and any headless setup all work differently, and an agency that has only ever configured server-side tracking through a Shopify app will struggle. The gap is rarely conceptual; it is practical, and it surfaces as weeks of delay while somebody learns your platform on your budget.

The multi-storefront and B2B capabilities also create measurement complexity that most agencies do not encounter. Several storefronts sharing a catalog, or wholesale pricing alongside consumer pricing, needs attribution that keeps them separate. When weighing the five agencies above, ask directly how many BigCommerce accounts the assigned team has actually worked on.

What actually separates a good bigcommerce agency from a bad one

Genuine platform experience, not Shopify experience adapted
Tracking, feeds, and headless implementations differ enough that platform familiarity saves real time. Ask how many BigCommerce accounts the specific team assigned to you has run, not how many the agency claims overall, and be direct about it, because the answer is frequently very few.
Multi-storefront measurement kept clean
If you run several storefronts on one catalog, whether by region, brand, or channel, attribution has to keep them distinct or the reporting becomes an average that describes none of them. Ask how the agency handles multi-storefront tracking and reporting before assuming it is straightforward.
B2B and wholesale handled as a separate motion
BigCommerce has strong native B2B features and many brands use them, which means customer-group pricing, quotes, and longer cycles sitting alongside consumer sales. Ask whether the agency has advertised into a gated wholesale motion, since it needs different creative, pages, and conversion definitions.
Feed management without a plug-and-play app
Feed tooling is less turnkey here than on the largest platform, so feed quality depends more on deliberate configuration and monitoring. Ask who owns the feed, how it is generated, and what alerts exist when products drop out or prices drift.

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 ranked first on a list Sagum publishes?

Because we publish it, and this is our competitive comparison rather than 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 genuinely leads a dimension we say so in their entry. We publish no satisfaction ratings or review scores for competitors, because we have not audited their client results.

Does platform choice actually change agency selection?

Less than platform-specific marketing suggests, but more than most agencies admit. The strategy of profitable acquisition is largely platform-independent. The implementation of tracking, feeds, and site testing is not, and an agency learning your platform during onboarding costs you weeks. The reasonable question is not whether they are a certified partner but how many accounts the assigned team has actually run on it.

How do we measure several storefronts on one catalog?

By keeping them genuinely separate in the tracking architecture rather than filtering after the fact. Each storefront needs its own conversion identity so performance, margin, and customer behavior can be evaluated independently. Brands that discover this late usually find that one storefront has been subsidizing another for months without anyone being able to see it.

Is the smaller app ecosystem a real disadvantage for marketing?

It is a real difference and a modest disadvantage in convenience. Fewer turnkey integrations means more configuration work for tracking and feeds, and occasionally building something that would have been a one-click install elsewhere. The offset is that you have fewer third-party scripts slowing your site and fewer apps quietly interfering with tracking, which is a genuine benefit rather than a consolation.

Should we go headless, and does that change our advertising?

Headless can improve performance and flexibility, and it definitely changes implementation. Tracking, tag management, and landing page workflows all become development tasks rather than platform settings, which slows iteration unless your team is set up for it. If you are considering it, involve whoever runs your advertising in the decision, because a headless build that ignores measurement requirements is expensive to retrofit.
