International expansion is a major growth priority for enterprise brands. HSBC research in 2026 of over 2,700 companies found that 77% of surveyed businesses plan to expand into new overseas markets within the next two years.
But international marketing and expansion into new markets have become increasingly complex because of regulatory uncertainty, shifting trade conditions, and regional differences.
To address those challenges, enterprises partner with an international marketing agency to execute their global growth strategy.
A top international marketing agency would typically combine global coordination with local execution to help enterprise brands adapt creative strategy, media planning, localization, research, digital marketing, and performance measurement without losing consistency in brand voice or identity.
This guide explains what to evaluate when comparing agencies for international market expansion and includes a thoroughly vetted list of recommendations for brands looking for partners with proven cross-border capabilities.
The right international marketing agency depends on how you plan to expand. Enterprise brands should prioritize agencies with proven experience in their target markets, strong local execution, relevant channel expertise, and a clear approach to compliance and performance measurement.
Here are 11 top picks based on our research:
For effective, compliant international marketing, enterprise brands need an agency that can coordinate globally with strong local-market knowledge, disciplined brand stewardship, and the operational capabilities required for cross-border execution.
The following criteria can help narrow the field.
If you have a specific target market or region, use that as the baseline selection criterion. Look for an agency that operates in that region and has experience in that market.
Some global ad agencies maintain their own local offices, while others rely on regional partnerships or networks of local-market talent.
Local presence in the target market can help, but it's not always a requirement. It comes down to the expansion strategy and the channels you're activating campaigns in. For instance, a digital marketing agency could run social media campaigns for your brand in a specific country without having an office there.
But the agency must be able to show meaningful knowledge of local behavior, culture, media habits, platform differences, and regional rules. Even in campaigns that are managed entirely online, market-level optimizations and cultural relevance remain important.
Ask who will manage local execution, whether native-language expertise is available, and how closely regional teams coordinate with the global account.
International campaign experience is useful, but experience supporting actual market entry is more valuable.
Look for case studies showing how the agency helped a brand launch into a new country or region, build awareness from scratch, generate qualified leads, establish an eCommerce presence, or adapt an established brand for a new customer base (depending on your expansion goal).
Strong examples should explain the challenge, research process, brand strategies used, local-market adaptations, media spend, and measurable business outcomes. Ideally, the agency should have worked with companies of similar scale, complexity, or sector.
The right agency will do more than execute campaigns. It should help shape an international go-to-market (GTM) strategy based on research, customer insights, competitive conditions, channel economics, and regional growth opportunities.
Even if you're already present in a different region, the agency handling marketing should have a growth mindset.
Strategy services may include:
For B2B brands, this may also involve account focus, ABM strategy, thought leadership programs, or qualified lead generation.
Ask how the agency approaches research and performance measurement before launch.
Pick a partner that uses analytics, performance tracking, and data-backed creative decisions to continually refine the strategy.
An agency's service offering should match the channels and infrastructure your expansion requires.
Depending on the market and business model, that could include:
Also assess whether the agency understands how platforms perform differently by country. A strong global marketing agency should build the channel strategy around those differences instead of applying the same media management model everywhere.
Pro Tip: Pick a full-service marketing agency for global expansion if you're employing a diverse mix of marketing channels. That way, you have a simpler vendor relationship instead of juggling many different agencies for specific channels or services.
International marketing introduces compliance considerations that can directly affect targeting, customer data, advertising technology, and campaign execution.
The best agencies for international expansion online usually understand the major privacy and advertising rules in the regions where you plan to operate and know when specialist legal guidance is required.
For example, campaigns targeting European users may need to account for GDPR (General Data Protection Regulation), while expansion into Brazil may involve LGPD (Lei Geral de Proteção de Dados Pessoais) requirements.
Privacy rules can influence cookie consent, customer data collection, remarketing audiences, and how first-party data is shared across platforms.
Also, regulatory knowledge shouldn't be limited to data privacy. Depending on the industry and market, brands may encounter restrictions around advertising claims, influencer disclosures, promotional offers, and content rights. This is especially true for regulated industries like food, health/wellness, and finance.
For enterprise brands operating across several jurisdictions, the agency should have a clear process for coordinating compliance between global and local teams.

We selected the agencies on this list based on their ability to support international growth beyond basic campaign execution. We prioritized firms with:
Here's our recommendation of the best international marketing companies to support a variety of expansion goals in different markets and industries:
Omnicom is one of the largest global marketing organizations that brings together agency networks and specialist businesses across advertising, media, branding, commerce, PR, production, experiential, and precision marketing.
Its scale is a major advantage for enterprise brands expanding internationally. Omnicom virtually operates in all regions and can combine centralized strategy and brand stewardship with local-market talent and execution.
Its Omni platform connects data, identity, media, creative, and performance measurement, while its media network provides substantial global buying and planning capabilities. After acquiring Interpublic in late 2025, Omnicom also gained additional agencies and technology assets, including Acxiom, McCann, Weber Shandwick, Initiative, and KINESSO.
Crowd positions itself around combining global reach with local knowledge, which makes it particularly relevant for brands entering markets where cultural adaptation matters as much as campaign scale.
They've helped brands with localized creatives for campaigns in culture-conscious markets like the Middle East. And that's thanks in part to their diverse team of over 25 nationalities. Its Games of the Future campaign, for example, operated across nine social platforms and six languages.
Other campaigns, like the one for Premier Inn, also show positive business impact. They report a 46% increase in direct website bookings and a 262% lift in booking revenue for the hotel chain.
R/GA is an international marketing agency with expertise in branding and design. It can help with expansion when the challenge goes beyond simply buying media in another country. They can be a more strategic partner for cross-border marketing with solid brand strategy, technology, and creative content.
Its growth strategy practice specifically includes identifying new customers and market opportunities, while its campaign capabilities include omnichannel strategy, global content production, social and influencer activation, and integrated campaigns designed to work across platforms and cultures.
That combination can be valuable when an established brand needs to preserve a consistent identity. When Moncler became a recognizable name worldwide, R/GA developed the company's first direct-to-consumer, omnichannel digital experience for a global customer base.
Fieldtrip is a full-service consortium of agencies that cover a wide range of strategy, media, and creative services. Its agency ecosystem is backed by a sizeable global team with expertise in awareness- and conversion-focused campaigns across markets.
As a growth-focused agency, its capabilities span channels like search, social media, and connected TV, which can deliver strong ROI in challenging, saturated markets.
In international marketing, Fieldtrip's unique proposition is its creator marketing expertise. Documented campaigns show access to influencers and micro-creators with niche, local followings. For example, Nielsen IQ used their services to activate creator-led campaigns in 19 countries.
Wieden+Kennedy is an international marketing agency that considers creative strategy and cultural relevance as central to international growth. The independent agency has spent more than 40 years building and transforming major global brands, with capabilities spanning creative, media, social, design, and strategy.
Its actual presence in major markets is a big strength and relevant for enterprise brands looking to activate campaigns with a local touch. The team includes more than 120 people representing 26 nationalities.
Wieden+Kennedy is best suited to international expansion where brand identity, creative content, social conversation, and culture-heavy moments matter more than purely performance-led customer acquisition.
Oban International is more specialized than many of the large global agencies on this list. Since 2002, it has focused specifically on helping brands grow across borders through paid media, SEO, content, social, and PR.
Its biggest differentiator is its LIME network, which gives the Brighton-based team access to more than 450 people living in over 80 markets who provide insight into local behavior, language, culture, and search habits.
That model takes localization seriously. Oban uses its in-market specialists to adapt keywords, messaging, visuals, ad creative, user journeys, and campaign structures around how customers actually search, shop, and respond. That expertise makes it best for enterprises that need international marketing focused on sales and revenue growth.
Ogilvy (owned by WPP) is a great pick for international expansion when brand building and cultural relevance matter as much as reach. It handles creative strategy, design, and production through its vast network of creative and advertising talent.
Beyond campaign creation, it also provides consulting, customer experience, PR, social influence, and other communications capabilities. That structure can help enterprise brands maintain a recognizable global identity while adapting messaging, visuals, and brand campaigns to local behavior.
Ogilvy worked on global campaigns for Coca-Cola's FIFA World Cup activity, alongside locally developed work across markets worldwide. That shows they can manage brand image for international companies.
Hallam is a B2B marketing agency based in the UK that's a strong fit for B2B companies that need international growth to translate into pipeline. Its paid media offering includes Google Ads, paid social, programmatic, Connected TV, and ABM, with performance tracking tied to pipeline contribution and revenue.
Its international paid media experience is clear. For global commerce platform WEX, Hallam ran an omnichannel campaign across seven markets, using Google Ads, programmatic display, native media, and other channels. The campaign generated 18% more leads than its target while spending 10% less than forecast.
Hallam can also help establish organic visibility for demand and lead generation for B2B companies going international. Its SEO and AI search services can help localize content for better rankings and citations.
Dentsu Creative is the global creative network within dentsu, built to bring creative, media, customer experience, commerce, and data capabilities closer together. Its "borderless" model gives brands access to more than 9,000 creative specialists globally. The broader dentsu network provides media and CXM expertise across roughly 120 countries.
Its international strength comes partly from dentsu's ability to combine centralized brand strategy with local creative teams. Heineken, for example, has worked with Dentsu on digital media both in Brazil and globally, while Dentsu Creative has expanded its remit to include creative communications for several Heineken portfolio brands in Brazil.
Dentsu Creative is a compelling option when international growth requires large-scale production and ad creative support, especially in a complex multi-market situation.
Vivaldi Group is a strategy and innovation consultancy that also offers marketing strategy and acceleration services. Its core strengths include competitive and growth strategy, brand positioning, research and insights, product and service innovation, customer experience, and go-to-market planning.
Because it's not a conventional global ad agency, it serves enterprise brands that need to decide where and how to grow internationally before committing significant media spend or launching performance campaigns.
For Foods From Chile, it used extensive research to develop positioning and an integrated campaign to increase demand for Chilean food products in the US. The strategy combined digital marketing, influencer activation, retail partnerships, events, and a new visual identity. It worked so well that US consumers associated Chile with healthy food.
ICS Digital is a digital agency specializing in international search and content-led expansion. It can create content in over 100 languages to help enterprise brands localize for search engines and make organic discovery easier as they target new markets.
Beyond local SEO and content marketing, the agency also handles social media and digital PR. Its international experience is especially clear in regulated and highly competitive sectors. For trading brand IG, ICS built a multilingual SEO and digital PR strategy across 16 markets, including activity in DACH, Scandinavia, LATAM, ASEAN, the UK, and the US
ICS Digital is, of course, for companies whose international growth strategy depends heavily on organic visibility, earned media, and localized search behavior (like ecommerce, service providers, and mobile apps).
Your first consultation should help you determine whether the agency understands both the strategic and operational realities of international expansion.
Go into the meeting with clear priorities, but also use it to test how the agency thinks about market entry, localization, global coordination, and performance.
Keep in mind, the first consultation isn't for a finished international marketing strategy ready to go. In fact, it's an opportunity to determine whether the agency has the experience, local-market understanding, strategic depth, and execution capabilities needed to become a credible partner in your global growth.
The checklist above ensures you leave the meeting with enough information to confidently start the partnership or move on to the next candidate.
Your marketing agency partner's physical presence in a market can help when campaigns require local coordination and support, such as OOH campaigns or local TV ads. For entirely digital expansion campaigns, local presence isn't necessary.
Paid campaigns across search, social media, TV/connected TV, and out-of-home usually work best for creating awareness for a new brand in the market. Influencer partnerships can also be highly effective for reaching relevant audiences in a new country or region. Choose channels and platforms according to your business niche and where your potential customers are.
Corporate marketing services may charge a monthly retainer or a project-based fee based on the scope of services. Typically, marketing services supporting large-scale expansion efforts can cost hundreds of thousands of dollars, especially when paid media is involved.
Fieldtrip offers end-to-end strategy, creative, and media services to support market expansion for enterprise brands. We offer market research, competitive intelligence, media planning, creative strategy, media buying, creative testing, performance analytics, and attribution. Our strategists can work with your brand to devise the best market-entry approach, while the creative, media, and data teams run the actual campaigns across channels.
