The 8 best B2B SaaS marketing agencies in Europe in 2027

Hiring a marketing agency is one of the bigger bets a B2B software company makes. Get it right and you have a team that builds pipeline across markets. Get it wrong and you can lose a lot of time, money and internal goodwill.

So rather than crowning a single winner, in this list of the best B2B SaaS marketing agencies in Europe, we paired each agency with the kind of company it fits (and we state plainly where it doesn’t!). We included agencies based on how much of their work is for B2B software and tech, whether they publish client results, what independent reviewers say about them and how openly they describe the way they work. None of them paid for a spot.

1. Unmuted: best for high-ACV SaaS that need positioning and a full team

Unmuted is us: this is our blog. We’re a B2B marketing agency in Amsterdam for SaaS companies with a high ACV and long sales cycles. Through The Growth Program, every client works with at least four of our specialists across positioning, content, video, web, ABM, paid media and AI search.

We start with positioning, because campaigns only scale when the message is clear. Then, we can make a more informed decision about which marketing playbooks, strategies and channels to tackle first. For example, Backbase, that meant establishing shared funnel definitions for sales and marketing, turning a podcast into thought leader ads and restructuring a global LinkedIn account. After working with us, Embed, a payments start-up selling across Europe, went from almost no marketing to twice as many inbound requests, with almost a third coming from ICP-fit companies. And at Studytube, a full go-to-market rebuild raised conversion by 20 to 30% from lead to SQL to opportunity.

Our team works in Dutch, English, German and French, among other languages, which makes us a great partner for SaaS companies operating in or considering expanding to Europe. We charge a monthly retainer based on the services you use and never a share of your media spend.

Choose Unmuted if: you want positioning, content, video, web and paid media from one team, built on a clear message and tied to pipeline across European markets.

Not the right pick if: you only want one channel managed, or you’re below €1M in ARR and haven’t raised funding yet. A specialist in the channel you want to manage will serve you better.

2. SaaStorm: best for SEO and AI search tied to pipeline

SaaStorm is a B2B SaaS marketing agency, registered in London, that works with European software teams from pre-seed to Series D. Its core services are SaaS SEO, answer engine optimization, content marketing and AI-assisted content production, with design, web development and paid ads available as add-ons.

Its case studies report pipeline and revenue rather than traffic alone. For Asora, SaaStorm reports they achieved €20M in qualified pipeline and €2.2M in closed-won ARR in nine months.

Every engagement starts with a short discovery phase, after which SaaStorm works on a monthly retainer. It doesn’t use fixed packages, so the scope is agreed during discovery. If you add paid ads, those are billed as a percentage of ad spend.

Choose SaaStorm if: organic and AI search are your main pipeline channels and you want a team that reports on pipeline, not just traffic.

Not the right pick if: paid media is your main growth lever and you want it run by a paid specialist.

3. Holini: best for SaaS teams with large paid search budgets

Holini is a paid media agency registered in Tallinn, with a fully remote team spread across over seven countries. It focuses on paid search (Google and Microsoft Ads) and paid social (LinkedIn and YouTube), with analytics and tracking work across tools such as HubSpot, Salesforce, GA4 and BigQuery. Landing page and creative design are available as add-ons.

Most of its clients are software and tech companies and you can see examples of its work through case studies. For DeskTime, Holini reports an 86% increase in qualified leads and a 106% increase in paying customers over two years. It also has 40 client reviews on Clutch, including recent ones.

Holini says it fits companies that already invest $10K or more a month in PPC ads or will soon. Fees aren’t listed on its site, so pricing may be something you need to check in the first conversation.

Choose Holini if: you spend serious money on Google and LinkedIn ads and want them run, tracked and measured by specialists.

Not the right pick if: SEO, content or video matter more to you than paid, or you spend well under $10K a month on ads for now.

4. Gripped: best for UK software companies past £2M ARR

London-based Gripped serves software, AI and tech businesses that have passed roughly £2M in ARR. The team covers go-to-market strategy, demand generation, ABM, paid search and social, SEO, GEO, and website design and build.

It works on a monthly retainer and advises planning a separate media budget on top of its fee. It also has 32 client reviews on Clutch.

Gripped works in English and focuses on British clients. Its site describes both rolling contracts with three months’ notice and six-to-twelve-month commitments, so ask which applies to you before you sign.

Choose Gripped if: you’re a British software company past £2M ARR looking for one partner across paid media, ABM and search.

Not the right pick if: your campaigns have to run in languages besides English or you don’t have revenue yet.

5. YOYABA: best for DACH software companies above €5M ARR

YOYABA is a Hamburg agency that works with B2B software companies, mainly in the DACH region, with a site in German and English. Its offer is split into paid growth, organic growth (SEO and GEO), RevOps and a combined revenue marketing service. Plus, it builds some of its own AI tools.

Each service has its own monthly fee and, for paid media work, YOYABA also charges a percentage of ad spend. You can check out its complete pricing on its website.

YOYABA’s packages are built for software companies grossing above €5M ARR and its paid work is for teams spending at least €10K a month on ads. On average, clients stay for more than 12 months. You can see some of its client results on the website too. For example, for loxo, YOYABA reports 20 hand-raisers and seven times the pipeline in 24 days.

Choose YOYABA if: you’re a DACH software company above €5M ARR that wants paid, organic and RevOps handled by one team.

Not the right pick if: you’re below €5M ARR or you prefer a fee that doesn’t grow with your ad spend.

6. The Growth Syndicate: best for Benelux companies that want ABM

The Growth Syndicate is a young agency, founded in 2024, with offices in Amsterdam and New York. It works with B2B SaaS companies, but also with industrial manufacturing, professional services, AI, fintech and medtech firms. Its services range from go-to-market strategy, positioning and ABM to paid media, SEO, content, websites and RevOps. It also offers a fractional marketing lead.

Its case studies focus on account-based work. For Nobel, it reports €1.5M in inbound pipeline and a 206% return on paid spend between January and September 2025.

The Growth Syndicate works on an hourly model with a monthly minimum and no lock-in: you can cancel at any time with 30 days’ notice.

Choose The Growth Syndicate if: you’re a Benelux tech or industrial company that wants ABM and go-to-market strategy without a long commitment.

Not the right pick if: you want an agency that works exclusively with software companies or a long track record of independent reviews.

7. Skale: best for product-led SaaS focused on SEO

Skale is a London-based agency that does organic growth only: SaaS SEO, GEO and AI brand mentions, link building, content production and website migrations. Its clients are mostly product-led software companies such as Holded, Slite, Attest and Happy Scribe.

Its homepage reports results such as a 450% increase in monthly sign-ups for Holded and a 520% increase in demo requests for Attest, though without time frames. Its client voice is strong: 21 reviews on Clutch, several of them from the last few months.

Skale doesn’t publish its fees.

Choose Skale if: organic sign-ups and AI search visibility are your main growth levers and you want a specialist focused only on that.

Not the right pick if: you need paid media, a website build or a broader marketing team.

8. Omnius: best for SaaS and fintech SEO

Omnius is a remote-first agency with headquarters in London and Belgrade. It works with SaaS, AI and fintech companies on B2B SEO, GEO and answer engine optimization, programmatic SEO, content, and website development and conversion work.

You can check some of the results it has achieved for its clients on its website. For example, for Myos, it reports a 227.9% increase in sign-ups in six months and for AuthoredUp 110% organic growth in six months.

Omnius says it doesn’t use minimums or restrictive clauses and it doesn’t publish its fees. Its Clutch profile doesn’t have reviews yet, so make sure to ask for references.

Choose Omnius if: you want SEO and AI search work with dated results and no long commitment.

Not the right pick if: you need paid media or you want independent reviews before you talk to an agency.

How do you choose a B2B SaaS marketing agency in Europe?

Start with what you actually need. Managing one channel well is a different job from having a team that rebuilds your positioning, content and campaigns. Once that’s clear, check whether the agency’s idea of success matches yours: traffic, leads and pipeline are not the same thing.

Next, look at the people who will work on your account. That’s the check most buyers skip, according to our founder, Max van den Ingh:

“Doing marketing for a consumer brand is completely different than doing marketing for a B2B SaaS company. When an agency tells you their performance marketer has ‘8 years experience’, I’d check how many of those years were in a relevant field. Selling t-shirts on a timeline with a 30-day money back guarantee is not the same as selling $100k software over a 9-month sales cycle.”

Max van den Ingh, Founder at Unmuted

Visibility before the first sales conversation matters more than most teams think. 6sense’s research on European B2B buying journeys found that the winning vendor was already on the buyer’s Day One shortlist 92.4% of the time. An agency should help you get onto that list, not just capture demand once buyers arrive.

These are the questions you should be asking in your first meeting:

• What does the agency report on and how does it link those numbers to pipeline and revenue?
• Who will work on your account and how many years have they spent in B2B software?
• Has it delivered results for companies similar to yours, in your markets?
• Can it work in the languages your buyers speak?
• What will you pay, how long are you committed and how much notice do you have to give?

Which warning signs should you look for in a B2B SaaS agency?

The biggest one is a team without real B2B SaaS experience. When companies come to us after a bad experience with another agency, Max says that is usually what went wrong: “Often the other agency’s team had no real experience with B2B SaaS marketing and go-to-market. They may have some SaaS customers, but that doesn’t mean they are good at it.”

Proof you can’t check is the related warning sign. A strong result names the client, gives a metric and says over what period it happened. If an agency can only show percentages without a client or a time frame, ask for the full story before you use it as a reference.

It isn’t always the agency, though. Max is just as direct about the client side: “Business owners in particular can be very convinced of the value of their own product. But often the product is not great at all, making it impossible to achieve impressive growth numbers through marketing alone.” So be honest about your expectations before you sign anything. No agency can market its way around a weak product.

Also look out for:

• The agency skips your positioning. If it goes straight to channels and budget without asking what you stand for, it will only amplify whatever message you already have, weak or not.
• Its terms are unclear. If the minimum term or notice period changes depending on who you ask, get it in writing before you sign.

What changes when you market in several European countries?

One of the most common mistakes we see is when agencies (or companies!) treat Europe as one market. “On paper it makes sense,” says Max. “You create one go-to-market engine and launch it across countries. In reality, the buying journey is going to be different in every country.”

He sees it in how buyers evaluate software:

“In Germany, they will always want to test your software extensively. Even if it’s an enterprise tool. In the Netherlands people buy software based on a demo call, a business case and a good feeling through references.”

Max van den Ingh, Founder at Unmuted

Buying groups differ too. 6sense’s European buyer research puts the average European buying group at 9.2 people and at 11 in the Netherlands and Germany.

You also compete with local vendors in every country, companies that, in Max’s words, “have friends and family in that country, know about all the events and organizations in that country.” His advice is to “conduct market research like it’s day 1” for every new country, starting with four questions:

• Who are the competitors?
• What are their strengths?
• How do we compare?
• Which messaging should we use?

From there, tailor your approach per country. Ask any agency you’re considering how it would do that for your markets and which of them it has already worked in.

Should you hire a specialist or a full-service agency?

Go for a specialist when your positioning and content already work and one channel needs expert hands: SEO, paid search or LinkedIn. Several agencies on this list are built for exactly that.

When your channels have to feed into each other and your website and sales team depend on them, one team across disciplines usually works better. Our comparison of full-service and specialist agencies goes deeper into the trade-offs. If LinkedIn is your main channel, have a look at our LinkedIn ads agency list.

How do B2B SaaS marketing agencies in Europe charge?

Most charge a monthly retainer, a percentage of ad spend, hourly rates with a monthly minimum, or a mix. Ad budgets are always added on top of that. With a fixed retainer, the agency earns the same whether you spend more on media or less. Percentage-based fees can work when budgets are large; just ask what happens to the fee when your spend goes up.

Expect agencies to be asked to prove their value. In Gartner’s 2025 CMO Spend Survey, 39% of CMOs said they planned to cut agency budgets. That makes it reasonable to ask any agency how it will show results within the first quarter.

Common questions about hiring a B2B SaaS agency in Europe

These are the questions SaaS teams ask us most often when they compare agencies.

Should we hire an agency or build an in-house team?

Building in-house pays off when you can hire experienced people for every discipline you need and have enough work to keep each of them busy on a full-time basis. If you need strategy, content and paid media at the same time, or you’re launching in new countries, an agency usually gets you there faster. We compare both routes in Marketing agency vs. in-house team for European B2B SaaS.

Does my agency need to speak my buyers’ language?

It helps, but language is actually the smaller piece of the puzzle. The buying journey and the competition differ per country too, so ask whether the agency has run campaigns in that market, not only whether someone on the team speaks the language. More on this in our go-to-market framework for entering a new European market.

How long before an agency produces results?

Paid campaigns can produce leads within weeks, but pipeline from positioning, content and SEO takes longer. Give it a few quarters and measure pipeline instead of just first-month lead counts.
