Spain as a fintech base. When the math works.

The standard EU fintech playbook is well known by now. Get your EMI licence in Lithuania. Put your HQ in Ireland for tax. Hire your senior talent in London or Berlin. Open offices in Vilnius or Tallinn for back-office cost arbitrage. Use Estonia’s e-residency for the holding company shell if you are still early.

This playbook was written between 2015 and 2019, when those jurisdictions were actively courting fintech and the talent market for engineering was significantly cheaper, and it has not been seriously updated since.

The actual economics in 2026 are pretty different. Lithuanian engineering talent is saturated and priced closer to Polish or Czech rates than to Estonian rates of five years ago. London talent costs spiked post-Brexit and have not returned. Ireland’s headline tax advantage has eroded under OECD pressure and the Pillar Two minimum. The default playbook is using stale inputs.

The most underrated EU fintech base, by my read, is Spain. Not for everyone, and not the right answer for a Lithuanian EMI licence applicant or a US fintech that needs Irish tax structure. For a specific buyer profile that is more common than the industry talks about, Spain delivers a combination that no other EU jurisdiction currently matches.

I live in Spain and have spent enough time inside fintech hiring conversations, licence applications, and tax-structuring meetings across the EU to have a working view of the trade-offs.

Where the default playbook still works

Before the case for Spain, the case against being contrarian.

Lithuania is still the right answer when speed of licensing dominates the decision. The Lithuanian central bank operates faster than the Spanish CNMV or Banco de España, and the EMI process from filing to authorisation can complete in nine to twelve months versus fifteen to eighteen for Spain. If your business model is “obtain licence, passport across EU within twelve months, scale fast,” Lithuania remains the default and correct answer.

Ireland is still the right answer when corporate structure dominates. Irish corporate tax efficiency, while reduced, is still meaningful for SaaS and fintech companies with international IP. The legal and accounting infrastructure for managing Irish holding structures is mature. If your investors have specific opinions about Irish domicile, fighting that is not a battle worth picking.

London is still the right answer when capital markets access dominates. The depth of fintech-specific VC, growth equity, and late-stage capital in London is structurally larger than the rest of Europe combined. If you are a Series B or later business whose next round is the binding constraint, London is the centre of gravity.

The mistake projects often make is treating these answers as the answer to every fintech base question, when they are answers to specific questions.

What Spain actually offers

Talent depth combined with cost.

Spain has a population of 47 million, of whom a meaningful share are technically educated. The major engineering universities produce graduates competitive with any in Europe. English proficiency in the tech sector is high, often equivalent to Dutch or Scandinavian working standards.

The cost differential matters. A senior backend engineer in Madrid earns 40 to 60% less in total cost-of-employment than the equivalent in London or Berlin, and 20 to 30% less than in Amsterdam or Paris. Vilnius and Tallinn are cheaper still, but the talent pools are an order of magnitude smaller, and senior-engineer scarcity in those markets pushes effective costs up in tight talent niches.

For a fintech that needs to scale a 30 to 200 person engineering and operations team, this combination of pool size and cost is unmatched in the EU. Smaller pools work for smaller teams. Larger expensive pools work for the small number of providers with the funding to absorb the cost. Spain sits in the middle, and the middle is where most fintechs actually live.

The LatAm bridge.

This one no other EU jurisdiction offers. Spanish companies have natural commercial, cultural, and legal access to Mexico, Colombia, Chile, Peru, and Argentina. The major Spanish retail banks have a deep operational presence across LatAm. Spanish is the working language. Time zones overlap usefully with Eastern US hours, which matters for support models and for any cross-region operations.

For any fintech with serious LatAm ambition, basing in Spain rather than Lithuania removes friction at almost every operational layer: hiring of bilingual support staff, partnership conversations with LatAm institutions, navigation of regulatory landscapes that often borrow heavily from Spanish frameworks, and customer-side credibility with Spanish-speaking markets.

This is one of those advantages that does not show up on a spreadsheet until you try to execute the alternative. Run a Mexican client onboarding from a Vilnius office with no native Spanish speaker, and the bridge cost becomes obvious.

Banking and open banking infrastructure.

Spain’s PSD2 implementation is one of the more mature in the EU. The major retail banks maintain functional production APIs, treat fintech partnerships as strategy rather than tolerated experiments, and have internal teams that understand the BaaS and orchestration layer. Several of them have multi-year histories of fintech investment that have produced working ecosystems for vendors and partners.

For a fintech that needs partnership relationships with European tier-one banks, the operational distance from Madrid to a major Spanish bank conversation is much shorter than from Vilnius or Dublin. This sounds soft. In practice, it shortens partnership cycles by months.

Regulatory sandbox and startup law.

Spain launched a fintech regulatory sandbox in 2020 and updated the framework through the Ley de Startups in late 2022. The sandbox lets early-stage fintechs operate under regulatory supervision without full licensing, useful for product testing and investor evidence. The startup law also created visa categories that make it easier for international founders and senior hires to relocate to Spain, including a digital nomad visa with favourable tax treatment for qualifying individuals.

The combination of sandbox plus startup-friendly visa policy plus an established licensing path for graduates of the sandbox is competitive with the better-known offerings from Lithuania and Estonia, and superior to most other large EU economies.

Where Spain genuinely loses

Three real disadvantages. Pretending they do not exist is how the contrarian case becomes propaganda.

Licensing speed.

The EMI and PI licence processes in Spain run longer than in Lithuania, typically by six to nine months. For a project whose timing to launch is tight, this is decisive. The Banco de España is competent, but it has not been optimised for speed the way the Lithuanian central bank has been since 2018. If your business requires “licence in hand within twelve months,” Spain is the wrong choice.

Employer cost and labor law.

Spanish social security and employer contributions add roughly 30% to gross salary costs. Termination is more expensive and procedurally complex than in the UK, Ireland, or Lithuania. For a fintech that expects to scale fast then potentially restructure, this rigidity is a real cost. The 40 to 60% talent cost advantage I described above is calculated after these employer costs. Compute it before, and the advantage is even larger; compute it including severance scenarios, and the advantage narrows.

Capital ecosystem.

Madrid and Barcelona have functional Series A markets but Series B and later become harder. Most Spanish fintechs that scale past Series A end up bringing in London-based, Berlin-based, or US-based capital at the next round. This is not a disqualifier, but it means the local capital answer is not the same as London or Berlin. If you are at the stage where capital depth dominates your base-of-operations decision, that decision is rarely Spain.

The buyer profile that should consider Spain

A fintech with engineering and operations teams in the 30 to 200 person range, where talent cost is a material factor and senior retention matters. Where some component of the business model involves LatAm market access. Where the licence is either already obtained elsewhere and the company is passporting in, or the licence is acceptable on a fifteen to eighteen month timeline. Where the capital strategy assumes international fundraising rather than local-only.

This profile is more common than the industry talks about. Most growing fintechs fit it, the default playbook just does not surface Spain as an option, so fintechs do not run the calculation.

The buyer profile that should not

An early-stage fintech racing to obtain its first EMI licence with a twelve-month launch deadline. A company whose primary investors have a strong preference for Irish or US domicile. A team that requires a deep local Series B and later market. A founder team without any Spanish-speaking principal and no plans to spend significant operating time in the country.

For these profiles, Lithuania, Ireland, or London remain the better answers. The Spain trade only works when you can stay long enough to extract the advantages, and that requires either Spanish-fluent leadership or a willingness to invest in becoming so.

Evaluating an EU base

I would suggest deciding what dominates: licence speed, tax structure, capital depth, talent scale, or geographic reach. One of these will be the binding constraint. Do not try to optimise across all five.

If licence speed dominates, the answer is Lithuania.

If tax structure dominates, the answer is Ireland.

If capital depth dominates, the answer is London.

If talent scale at the 30 to 200 person band dominates, Spain is in serious contention with Berlin and Amsterdam, and beats them on cost.

If LatAm reach is a real part of the business, Spain is the only EU answer that works without compromise.

The mistake is to treat the default playbook as a substitute for asking which constraint actually binds. Most projects inherit the playbook from their VCs or from the founders they followed, without re-deriving it for their own situation.

The Spain arbitrage exists because the playbook has not been updated. As more of us run the calculation honestly, the arbitrage will compress. And for now, for the specific profiles described above, the math is unambiguous and the conversation rarely happens.
