B2B marketing agency Spain Madrid, Barcelona and Valencia
GTM Quest is a London go-to-market agency for B2B teams selling into Spain.
We build the plan, the account lists and the outreach around Spain's rule that commercial email needs prior consent, companies included.
We also help you brief a Spanish marketing agency where the work needs Spanish.
Then the guide: how B2B marketing is bought across Spain's three agency cities, the rules, and eleven Spanish B2B agencies re-checked on their own websites in September 2026.

01/ our service
Selling into Spain what GTM Quest does for you
We are based in London, not Madrid.
What we bring is the go-to-market work that decides whether a Spanish launch pays: which accounts to target, what to say, how to reach them lawfully under Spanish rules, and how to measure it.
01
A go-to-market plan for Spain
Which segments to enter first, which accounts are worth pursuing, and what you will say to them.
Written down in the first weeks while the first conversations run, and before any money goes on media or an agency retainer.
02
Account lists you own
Target accounts and the people in each buying group, enriched in Clay and held in a Postgres database that stays with you.
Built for Spain company data, not a UK list with the country changed.
03
Outreach that respects local rules
Email, LinkedIn and calls sequenced around what the Spain rules allow, not around the UK's corporate-subscriber exemption, which most of Europe does not have.
04
LinkedIn and founder-led content
Posts and paid LinkedIn aimed at the same account list, so outreach arrives from a name buyers have already seen.
English first, local language where it matters.
05
A local agency, briefed properly
Where the work needs Spanish (or Catalan) content, events or PR, we write the brief, shortlist Spanish agencies and sit in the pitch with you, so every agency quotes for the same thing.
06
A system you keep
Documented, trained and handed over.
The lists, sequences, dashboards and playbooks stay with you when the engagement ends.
Spain's consent rule pushes the first touch onto LinkedIn, events, content and paid media, with email only after consent.
That is why our Spanish motion starts on day one through LinkedIn, content and warm introductions.
See our ABM agency and demand generation pages.
02/ engagement
How we work with teams selling into Spain
Every engagement starts the same way: the motion on day one through LinkedIn, content and warm introductions, with the system built around it.
The difference is who runs it afterwards.
How much of your Spain go-to-market do you want to own?

03/ the market
How B2B marketing is bought in Spain three agency cities
Spain's statistics office counted 3,310,824 economically active companies at 1 January 2025, 1.7% more than a year earlier.
The business base is young in parts: 19.9% of active companies were under two years old, while 18.9% were 20 or more.
The B2B agencies on this page cluster in three cities.
Madrid has the go-to-market and HubSpot consultancies: mbudo, The Revenue, Reux Digital.
Barcelona has the inbound, martech and lead-generation shops: Cyberclick, Gotoclient, GO2JUMP.
Valencia has Sakudarte, which describes itself as an industrial B2B marketing agency, and Connext.
Spanish agencies are overwhelmingly domestic-facing and Spanish-language.
A few run genuine English operations (Gotoclient, Reux Digital, Cyberclick, mbudo); several doing real international work publish no English at all.
Marketing agency Spain, Barcelona or Madrid?
Choose the agency by the work, not the city.
On this page the HubSpot and RevOps specialists are in Madrid and Barcelona, the self-described industrial specialist is in Valencia, and the corporate-reputation firm, Ulled, works from Barcelona, Madrid and Lisbon.
The trade body
ACT, Asociación de Agencias de Creatividad Transformadora was founded in 1977 and has 27 member agencies, according to its site.
Membership shows an agency is established; it is not a quality mark, and most B2B specialists are small.
04/ the rules
B2B email in Spain LSSI Article 21
Spain has no B2B carve-out for marketing email.
General information, not legal advice.
What this means in practice. A UK team relying on PECR's corporate-subscriber exemption would be non-compliant in Spain from the first email.
Spanish B2B programmes lean on LinkedIn, events, content, webinars and paid media, with email after consent.
IOMarketing's own contact form, for example, says it will only send advertising with prior authorisation (IOMarketing).
05/ language
Working with a Spanish agency in English watch for fake bilingualism
Spain ranks 36th of 123 in the EF English Proficiency Index 2025, with a score of 540; Madrid scores 560 in EF's city table (EF EPI 2025 report).
English is common in multinational and technology firms, less so in industrial SMEs.
On this page, Gotoclient, Reux Digital, Cyberclick, mbudo and The Marketing Hub run English sites.
Connext, Sakudarte, The Revenue, IOMarketing and GO2JUMP lead in Spanish.
An /en address is not proof: open a case study in English before you assume English delivery.

07/ build or buy
A Spanish agency or a London GTM partner? honest trade-offs
Teams entering Spain often use both, in order.
→ Set the plan and accounts first; bring in a Spanish agency for Spanish-language execution.
→ A network gives reach; a GTM partner gives one system.
→ Prove the motion with us, then hire into it.
08/ buying
How to choose a B2B marketing agency in Spain five steps from abroad
The order matters.
Each step removes agencies that would have wasted a pitch meeting.
Write one brief and send it to everyone
Your ICP, the Spain segments you want first, the budget band, what you already run and what "good" looks like after six months.
Agencies quoting on the same brief can be compared; agencies quoting on a phone call cannot.
- ✓ ICP and first segments
- ✓ Budget band, not a number
- ✓ What you run today
- ✓ The measure of success
Test the language, not the homepage
Open three deep pages on each shortlisted site: a case study, a service page, a blog post.
If they fall back to Spanish, delivery probably will too.
Fine with a local team; costly without one.
- ✓ Three deep URLs
- ✓ Case studies in English?
- ✓ Who writes the English copy?
Ask for the lawful basis of the first email
LSSI Article 21 bans promotional email without prior request or express authorisation, and the AEPD says GDPR legitimate interest does not override it (AEPD).
Any agency that cannot explain how its first outbound email is lawful in Spain should not be sending it for you.
- ✓ Generic or named addresses?
- ✓ Consent or exemption?
- ✓ How objections are recorded
Check credentials where they are issued
Look up partner tiers in the vendor's own directory, such as HubSpot's Solutions Partner directory, and membership on the trade body's site (ACT).
A badge on the agency's homepage proves nothing on its own.
- ✓ Vendor directory, not the badge
- ✓ Trade-body member list
- ✓ Named clients you can call
Start with a pilot you can end
Three months, a written scope, one region or sector first.
None of the eleven agencies here publishes prices, so ask for a fixed-scope pilot quote.
Keep the CRM, ad accounts and data in your name.
- ✓ Three months, written scope
- ✓ Break clause
- ✓ You own the data and accounts
09/ what it costs
What a Spanish B2B marketing agency costs why there is no range here
None of the eleven Spanish agencies on this page publishes prices on its own site.
Ask for the scope as deliverables per month and the team as named roles, then compare quotes line by line.

How this page was checked and what it leaves out
Each agency was re-read on its own website on 28 September 2026: homepage and contact or legal page.
Where a site does not state a city, the card gives the country.
Nothing comes from Clutch, Sortlist, GoodFirms or any other directory.
What is deliberately absent: a ranking, a price range, and founding years, awards or headcounts the agencies' current pages do not state.
The rule summary is drawn from the LSSI text and AEPD reports and resolutions; it is not legal advice.

12/ questions
B2B marketing in Spain FAQ
What buyers ask before hiring a B2B marketing agency in Madrid, Barcelona or Valencia, and about Spain’s rules on B2B email.
It depends on the job: mbudo or Cyberclick for HubSpot, Sakudarte for industrial B2B, The Revenue or Reux Digital for go-to-market consulting, Gotoclient for channel programmes.
Use the picker.
For the go-to-market plan itself, see what we do.
For martech and HubSpot, Cyberclick; for lead generation and channel marketing, Gotoclient; for industrial sectors, GO2JUMP.
See the agency list.
mbudo (HubSpot), The Revenue (go-to-market consulting), Reux Digital (B2B and SaaS consulting) and IOMarketing (SME digital marketing).
Only with prior request or express authorisation, unless the recipient is an existing customer buying similar products from you (LSSI Art. 21).
Companies are covered as well as people.
No. The AEPD says LSSI Article 21 applies as the specific rule and prevails over the GDPR's general regime for electronic commercial communications (AEPD).
Mass sending, or more than three commercial emails a year to the same recipient in breach of Article 21, is a serious infringement under the LSSI; a single email is a minor one (AEPD resolution).
None of the eleven Spanish agencies here publishes prices.
