Quick answer: The right ecommerce growth agency depends on your goals, the channels you use, and the work your internal team can manage. Agencies differ in their focus: some specialize in advertising or marketplace operations, while others cover several parts of an ecommerce business.
Most growing brands reach a point where one team can’t run every channel well. Amazon, Shopify, TikTok Shop, and paid media each need their own expertise. An ecommerce growth agency fills that gap.
Below, we compare 7 agencies by channel coverage, service depth, operating model, and the brands they serve. Each profile shows who the agency suits best. Use it to build a shortlist that fits how your business runs today.
How We Compared These Agencies
We reviewed each agency’s publicly described services across four dimensions: channel coverage, service depth, operating model, and the types of brands they serve. Public information can help identify potential options, but it cannot establish which agency will deliver the best results for a particular brand.
Use this comparison to build a shortlist, then ask each agency who will work on your account, which services are handled in-house, how progress will be measured, and how its team will coordinate with yours.
Top 7 Ecommerce Growth Agencies
1. Eva Commerce
Best for: brands that need connected management across Shopify, Amazon, TikTok Shop, and additional marketplaces.
Eva Commerce is a full-service ecommerce agency built around a connected growth-system model. Its public service scope covers Amazon marketplace management, Shopify management, TikTok Shop management, marketplace expansion, Google and Meta advertising, search and AI optimization, conversion and retention, creative and catalog operations, and ecommerce intelligence.
That breadth is the reason it sits first in this comparison. It is designed for a brand whose growth challenge is not limited to one channel. A Shopify store’s conversion rate may depend on paid acquisition quality, lifecycle campaigns, product merchandising, search visibility, and the way marketplace signals affect inventory and product priorities. Eva’s model is intended to bring those decisions into one operating system.
A suitable buyer is an established brand that wants one team to coordinate acquisition, conversion, retention, store operations, and marketplace execution. It is less suited to a company looking only for a narrow, one-off task such as a website redesign
Key services:
- Full-service Shopify, Amazon, and TikTok Shop management
- Google and Meta advertising
- Amazon and Shopify search and AI optimization
- Conversion, retention, email, SMS, and subscriptions
- Marketplace expansion and ecommerce intelligence
2. Code3
Best for: brands that want commerce, media, creative, and measurement coordinated within a performance-marketing model.
Code3 positions itself as an independent growth agency spanning strategy, media, commerce, creative, and measurement. Its public services include paid search, paid social, retail search, catalog management and discoverability, commerce creative, and performance measurement.
The agency is a sensible option for a brand where media strategy and creative execution are central to the growth plan. Its structure appears especially relevant to teams that need a partner to connect retail media, social, creative production, and performance reporting rather than manage only one ad platform.
Consider Code3 if your business has a strong ecommerce foundation but needs more integrated media and creative execution. In discovery, ask how it will coordinate with your internal ecommerce, merchandising, and operations teams; that relationship determines whether media learning turns into better onsite and product decisions.
Key services:
- Paid search and paid social
- Retail media and commerce
- Catalog management and discoverability
- Performance and commerce creative
- Measurement and strategy
3. Canopy Management
Best for: brands seeking full-service marketplace management across Amazon, Walmart, or Chewy.
Canopy Management publicly describes services across Amazon PPC, DSP, product listing optimization, Amazon SEO, creative production, account support, inventory management, revenue reclaim, and full-service Walmart and Chewy management.
That makes Canopy a strong shortlist candidate when marketplace operations are the central constraint. Its service menu goes beyond advertising into the commercial and operational work that often affects marketplace performance, including catalog, listing, customer service, inventory, and reporting.
It may be a better fit than a broad DTC agency for a company whose largest growth opportunity sits on Amazon or another retail marketplace. Before engaging, clarify ownership of inventory decisions, operational escalations, product data, and financial reconciliation with your warehouse or 3PL. Marketplace execution works best when those handoffs are explicit.
Key services:
- Amazon and retail-media management
- PPC and DSP
- Listing optimization and Amazon SEO
- Walmart and Chewy management
- Inventory, reporting, and revenue reclaim
4. Incrementum Digital
Best for: brands that want Amazon, Walmart, retail media, and TikTok Shop capabilities under one marketplace-focused partner.
Incrementum Digital publicly lists Amazon advertising, Amazon DSP, Walmart advertising, seller operations, retail media channels, TikTok Shop, creator connections, and creative services. Its scope is useful for a brand that is expanding from Amazon into a broader retail-media and social-commerce mix but still needs marketplace expertise at the center of the engagement.
This is a reasonable shortlist option when retail media is becoming more complex and the business needs a partner that can connect advertising, operations, creators, and creative. It is important to ask how the agency prioritizes channels and how it will measure overlap between retail media, marketplaces, and DTC activity.
Key services:
- Amazon advertising and DSP
- Walmart advertising and seller operations
- Retail media
- TikTok Shop and creator connections
- Creative services
5. Pirawna
Best for: consumer brands that want a dedicated, full-service Amazon growth partner.
Pirawna presents itself as an Amazon seller agency focused on account management, account setup, advertising, inventory and demand planning, and Amazon marketplace growth. Its public materials emphasize a tailored Amazon strategy rather than a one-size-fits-all playbook.
Pirawna is likely to fit brands whose principal commercial opportunity is Amazon and that want deeper hands-on support across account management, advertising, listings, and inventory planning. It is not positioned as a complete replacement for a Shopify, lifecycle, or paid-social team; buyers should treat it as a specialist marketplace partner and define cross-channel coordination clearly.
Key services:
- Amazon account management and setup
- Amazon advertising
- Inventory and demand planning
- Marketplace strategy and reporting
- Listing and brand growth support
6. Sophie Society
Best for: Amazon sellers seeking a focused PPC-management partner.
Sophie Society is positioned around Amazon PPC management, with a dedicated strategist, profit-oriented campaign structures, product-launch support, reporting, and Amazon advertising expertise. Its public service model is narrower than a full-service marketplace operator, which can be an advantage for a brand whose core issue is campaign structure, targeting, profitability, and PPC decision-making.
This is a sensible choice for a seller that already has solid listing, catalog, operational, and inventory processes but needs specialized help with Amazon PPC optimization. A buyer should ask how PPC recommendations will be connected to stock levels, pricing, promotions, listing changes, and total marketplace profitability.
Key services:
- Amazon PPC management
- Product-launch support
- Campaign restructuring and optimization
- PPC reporting and strategy
- Profit-focused advertising operations
7. My Amazon Guy
Best for: brands seeking broad Amazon execution, including SEO, listings, design, and account troubleshooting.
My Amazon Guy publicly offers full-service Amazon management, PPC, Amazon SEO, listing optimization, A+ content and design, account audits, troubleshooting, DSP, Walmart management, and selected DTC services. Its visible service breadth makes it a relevant option for a brand that needs multiple Amazon workstreams handled together.
The strongest fit is a seller with a meaningful Amazon business that needs both growth work and operational problem-solving. That may include catalog cleanup, listing optimization, structuring Amazon PPC campaigns, creative, account issues, or Seller Central support. The right discovery question is which team owns the ongoing commercial plan after the urgent technical or marketplace problem is fixed.
Key services:
- Amazon full-service management
- PPC and Amazon SEO
- Listings, A+ content, and creative
- Account audits and troubleshooting
- DSP and Walmart management
How to Choose Between These Agencies
Start by defining the work your team needs help with and which responsibilities you want an agency to own. Consider your priority channels, internal capabilities, budget, and the level of coordination needed across advertising, store operations, inventory, and retention.
When comparing agencies, ask these questions:
- What business constraints will you address first?
- Who will work on the account every week?
- Which services are handled in-house, and which are subcontracted?
- How will you account for margin, inventory, fulfillment, and product availability?
- What data will you use to measure progress?
- What will the first 30, 60, and 90 days involve?
- What falls outside your scope, and how will you coordinate with the people responsible?
Use the answers to compare each agency’s proposed scope, working process, and fit with your team’s needs.
The Right Growth Agency Is the One That Matches Your Operating Reality
There is no single best ecommerce growth agency for every brand. The best choice depends on whether you need cross-channel management, retail-media depth, Amazon operations, PPC specialization, or a more connected view of the customer journey.
For a multi-channel brand, the cost of fragmented execution can be high: paid media, store conversion, product availability, retention, and marketplace operations can all pull in different directions. The right agency reduces that fragmentation, establishes accountability, and helps the business make better commercial decisions over time.
Frequently Asked Questions
What does an ecommerce growth agency do?
An ecommerce growth agency manages the work that drives online sales. That can include advertising, marketplace management, listing optimization, conversion, and retention. Scope varies widely, so some agencies cover one channel while others manage several.
What is the difference between a full-service agency and an Amazon specialist?
A full-service agency coordinates several channels, such as Shopify, Amazon, and paid social, under one team. An Amazon specialist goes deeper on one marketplace. The right fit depends on where most of your revenue comes from.
When should a brand hire an Amazon PPC agency instead of a full-service partner?
Choose a PPC specialist when your listings, catalog, and inventory are already in good shape. If the main gap is campaign structure, targeting, or ad profitability, focused PPC support is often the most efficient choice.
How much does an ecommerce growth agency cost?
Pricing depends on scope, channels, and ad spend. Common models include flat monthly retainers, a percentage of ad spend or revenue, or a hybrid. Ask each agency for a written scope so you can compare proposals fairly.
How long does it take to see results from a growth agency?
Most agencies spend the first month on audits, onboarding, and setup. Early gains in advertising efficiency can appear within the first quarter. Broader growth across channels usually takes longer and depends on inventory and budget.
How should a growth agency work with your 3PL or fulfillment partner?
Agree on shared inventory data, promotion calendars, and stock thresholds early. When your agency and 3PL see the same numbers, ad spend stays aligned with available stock. That protects rankings and avoids paying for traffic you cannot fulfill.
