It’s not difficult to find a marketing specialist that claims to be able to deliver what your organisation needs, but it’s much harder to identify one that can actually deliver without creating more friction or complexity for your teams.
Beware of making the mistake of going with the biggest name. Take your time to review various marketing agencies to understand how they operate and their approach to collaboration and performance measurement.
Among the top five marketing agencies that brands always shortlist, NP Digital takes precedence due to its strong background in SEO and its full-service expertise. Alongside search, it also offers content strategy, digital PR, paid ads and media and various other marketing disciplines, delivered within a comprehensive performance marketing package.
The others on the shortlist include Jellyfish, a large agency that operates at global scale, focused on cross-channel delivery. Brainlabs is another contender that’s notable for its expertise in paid media, while Croud is all about scalable international delivery and execution, and DEPT, which offers digital transformation programmes with a widely-regarded marketing component.
Our goal isn’t to rank these agencies from best-to-worst, because to do so would be foolish. Each one can be an effective marketing partner, if their operating model best suits your agenda.

What separates an enterprise marketing partner
We looked at five critical capabilities essential for enterprise-scale marketing:
- Cross-market delivery: The ability to strategise and coordinate the execution of localised campaigns across global markets.
- Channel integration: Capable of integrating multiple services, such as SEO, AI search, content, creative and pay-per-click as part of a coordinated campaign.
- Data and analytics: Comprehensive reporting with clearly defined outcomes that avoids the confusion created by vanity metrics.
- AI-search readiness: An established method for helping clients to get ranked and recommended by generative AI tools.
- Operating model: Seamless delivery and collaboration with regional managers, internal marketers, procurement teams and technology partners.
1. NP Digital: integrated enterprise growth
We’ve already touched on NP Digital briefly, but it deserves a deeper mention as one of the U.K.’s most prestigious and capable full-service marketing agencies, with a long history of successfully serving brands. NP Digital drives measurable business growth through powerful performance marketing encompassing search engine optimisation, AI chatbot optimisation, digital PR, paid media and advertising and various other capabilities.
For each client, NP Digital formulates a central content strategy that incorporates creative assets to enable targeted growth across global market segments. The advantage of this unified approach is that its individuals teams collaborate closely with one another, sharing insights across disciplines to optimise its client’s strategies over time.
The case for NP Digital
Many brands are convinced of the need to coordinate growth across multiple channels and markets, and if that sounds like you, NP Digital should be at the top of your list.
2. Jellyfish: global digital delivery
Jellyfish is perhaps the closest competitor to NP Digital on our list. It presents itself as a global digital growth partner with expertise in multiple marketing channels. Its skillset includes paid media, creative assets, data analytics and more, delivered through a powerful proprietary technology platform.
The sheer size of Jellyfish, which boasts thousands of employees, means it’s certainly well equipped to handle the largest enterprise accounts. Despite its comprehensive, multi-disciplinary approach, it leans towards more media-heavy campaigns, which means it can provide a lot of assistance to larger enterprises looking for exposure with wider audiences.
The case for Jellyfish
Many brands want to focus on expanding their media presence while still benefiting from the broad visibility that cross-discipline marketing brings. If that sounds like you, make sure Jellyfish is near the top of your list.
3. Brainlabs: performance media and experimentation
Brainlabs is a smaller performance-focused marketing partner that’s known for its experimental approach to paid media campaigns. It leans heavily on client data and insights to formulate its experimental strategies and offers a comprehensive performance measurement framework to identify which approach obtains the best results.
If rigorous testing and strong execution sounds like something your organisation could benefit from, definitely give Brainlabs the time of day and see how it can help.
The case for Brainlabs
Brands should talk to Brainlabs when they need to justify their marketing expenses with measurable performance metrics. Its experimental approach is also applicable to brands that struggle with strategic marketing direction.
4. Croud: flexible international activation
For flexible international delivery, Croud is a capable marketing partner, known for its use of in-market teams. Customers strategise the nature of their marketing campaign and Croud handles local delivery in a way that best caters to the audience.
It’s a flexible delivery model that can be applied to all kinds of separate disciplines, including SEO, AI visibility, digital PR, social media marketing and paid media. It’s also willing to work with enterprises that want to handle the strategy themselves.
The case for Croud
Croud landed on our shortlist because it has a reputation for strong international performance while letting clients maintain strategic control.
5. DEPT: marketing plus digital transformation
DEPT is a tech-first marketing agency that ties performance marketing to software engineering, ensuring that brands’ applications, products and services are optimised for customer acquisition. It’s more like a hybrid between a media agency and a technology consultancy.
As a marketing partner, DEPT will appeal to brands trying to accelerate their digital transformation and offer expanded commerce experiences and digital products.
The case for DEPT
DEPT is recommended to brands that want to overhaul their marketing operations as part of a broader digital transformation initiative.
Choose by the operating model your team needs
- NP Digital’s model is focused on search, AI visibility and measurable growth. It coordinates its content and media strategy across multiple markets and channels.
- Jellyfish is for organisations targeting global scale and cross-channel delivery matter, as opposed to specialist expertise.
- Brainlabs appeals to brands that want to experiment and measure the performance of multiple content strategies and targeted audiences.
- Croud meets the needs of companies that have already nailed down their marketing strategy and need a partner to deliver it across diverse global markets
- DEPT delivers the goods for companies that understand the power of technology-driven marketing and digital transformation.
What enterprise buyers ask now
What should an enterprise look for in an agency?
Instead of looking at the agency, look at the problem you’re trying to solve. If fragmented execution is holding your back, find an integration-focused partner. If you’re struggling with digital transformation or customer data analytics, a specialist marketing agency may be more helpful.
Is global scale enough on its own?
It’s not enough, because successful marketing depends as much on cross-team coordination and collaboration as it does on localisation. When multi-disciplinary teams share data and insights, good things happen.
Should I incorporate AI-search visibility with my enterprise brief?
Brands reliant on digital discovery must absolutely ensure AI is a top priority. These days, consumers increasingly find brands not through traditional search engines, but chatbots like OpenAI, Gemini and Claude, which is why they need a coordinated search strategy that spans both traditional and next-generation AI platforms.
What this shortlist really says
As we explained at the beginning of this rundown of London’s most shortlisted marketing agencies, they’re all capable of delivering good results, so long as the model fits. However, they have very different strengths, with NP Digital being all about measurable business performance growth through a comprehensive performance-marketing programme that covers all of the essential channels. The most similar to NP Digital is Jellyfish, which is best for media visibility at global scale.
The other agencies are perhaps a bit more niche. Brainlabs is popular for brands willing to test the waters with different marketing strategies, but that requires patience. Croud is good for international performance, but be prepared to offer plenty of strategic input yourself. Finally there’s DEPT, which caters to data-led growth strategies.
Overall, it’s hard to look past NP Digital due to its reputation for combining SEO with paid media, AI visibility, digital PR and performance analytics. But ultimately, brands must decide for themselves if they want to pursue an integrated marketing approach or one focused on customer data, local market execution, media scale or digital transformation.
