FinTech is often associated with speed, convenience and disruption. But the businesses best placed to endure are usually those that understand, early, how deeply law and regulation shape the market they are trying to transform.
Behind the smooth interfaces, instant payments and ambitious growth stories lies a sector built on trust, customer funds, sensitive data and close regulatory attention. It is an industry where legal design is rarely peripheral. More often, it sits close to the centre of the business model.
The companies that navigate this well are often not the ones most determined to stay ahead of the rules, but the ones that understand the regulatory landscape sooner, structure themselves more carefully and adapt more intelligently than others. In that sense, compliance is not only about constraint. It can also be a source of resilience, credibility and competitive strength.
That is also why the legal questions in FinTech deserve attention. The sector sits at the intersection of payments, lending, investment services, data protection, outsourcing, cybersecurity and consumer protection, while new regulatory layers continue to emerge. What follows is a closer look at some of the central legal and regulatory difficulties in the industry, and at the issues that matter most for any business hoping not only to launch successfully, but to scale with confidence.
Some of Europe’s best-known FinTechs illustrate the point. Adyen scaled by building around a regulated acquiring model rather than trying to stay outside the system. Klarna’s growth depended not only on product design and distribution, but also on fitting its offering within consumer credit and payments rules across multiple jurisdictions. Wise, Revolut and Trustly likewise show that scaling across borders and product lines depends not only on technology, but on licenses, compliance infrastructure and business models that can withstand regulatory scrutiny.
FinTech – what is it?
FinTech is a term people use as if it has one clear meaning. It is a broad label for businesses that use technology to offer financial services in a smarter, faster or more accessible way. This can include payments, digital banking, lending, investing, insurance, financial infrastructure and crypto-related services. It is a wide category, and that is part of what makes it so interesting.
What these businesses have in common is not one specific technology. It is that they sit where finance, product design and regulation meet. From the customer side, the goal is usually to remove friction: faster onboarding, cleaner interfaces, instant payments, smoother credit journeys and less paperwork.
From the legal side, the picture is rarely that simple. As soon as a business starts moving money, holding customer funds, arranging investments, underwriting risk or handling sensitive financial data, the legal framework becomes part of the product whether the company wants that or not.
Not a separate area of law
That is why FinTech is best understood not as a separate legal discipline, but as a business area that brings together several areas of law at once. Financial regulation is the obvious starting point, but it is only part of the picture. FinTech also touches data protection, contract law, consumer protection,
outsourcing, cybersecurity, intellectual property and operational resilience. In practice, the hardest questions often arise where those areas overlap and proand give rise to complex assessments. A product team may be focused on speed and customer experience, while the legal analysis focuses on whether the service is in fact payment execution, credit intermediation, e-money issuance, investment advice or custody. Those distinctions are not just technical. They decide which rules apply, whether a license is needed and how the business needs to be structured.
Primary question: What financial service is actually being provided?
Two businesses may use similar technology and describe themselves in similar ways but still fall under completely different regulatory regimes. A payment initiation service is not the same as an acquiring model. An e-money wallet is not the same as a deposit product or an eIDAS wallet. In FinTech, what matters far more than the label a company uses is what it does in practice: Substance over form.
As members of EU/EEA, the FinTech sector has an increasingly complex set of rules. Payments are governed by PSD2, with PSD3 on the way. Investment services are governed by MiFID II. E-money institutions and payment institutions have their own authorisation and conduct frameworks. Crypto businesses need to consider MiCA. On top of that: AML obligations, GDPR, DORA, NIS2 and national supervisory expectations. These rules do not cover only the customer-facing service. They also affect governance, incident management, outsourcing, documentation, complaints handling, business continuity and the controls around technology providers.
Licensing is a pressure point
Licensing is both an asset and an investment, but it is also one of the clearest pressure points in FinTech. Operating without the right authorisation is not a small technical mistake. It can undermine the whole business model and, in the worst case, lead to sanctions that force the business to cease.
Regulators look at substance, not branding. A company may describe itself as a software platform, an infrastructure layer or a pure technology provider, but if it controls transaction flows, safeguards customer funds, decides how financial operations are carried out or otherwise plays a decisive role in the service, it may still be carrying on regulated activity. This can be especially hard to assess in newer business models, where products are deliberately designed to sit somewhere between software and financial service delivery.
You don’t have your own license but you still regulatory obligations
Even where a FinTech does not need its own license, regulation often enters through partnerships. Many FinTechs work with banks, insurers, payment institutions or investment firms rather than becoming regulated entities themselves. That can make commercial sense, but it does not remove legal complexity. Under outsourcing and ICT risk frameworks, the regulated institution remains responsible to the supervisor even when key parts of the service are delivered by a third party. This is why FinTech providers are often asked to accept detailed contractual obligations on audit rights, information security, incident reporting, business continuity, subcontracting and regulatory cooperation. Banking-as-a-service and embedded finance are good examples. They may look seamless from the outside, but legally they depend on a careful division of responsibility behind the scenes.
Data protection challenges
Data protection sits near the centre of most FinTech models. These businesses usually process large amounts of personal and financial data, often across several jurisdictions and through a network of service providers, banking partners and analytics tools. GDPR applies in full, whether the company
presents itself as a financial institution or simply as a software company. In practice, the hard questions are less about whether the rules apply and more about how the data flows are structured: who is controller, who is processor, what is the lawful basis, what happens when data is reused for analytics, fraud monitoring or AI training, and how international transfers are handled.
Operational resilience and DORA
Financial services are part of society’s core infrastructure, so resilience matters. Operational resilience has moved much closer to the centre of FinTech regulation. A few years ago, resilience was often treated mainly as an engineering or vendor-management issue. That is no longer enough.
Under DORA, financial entities and certain critical technology providers must be able to withstand, respond to and recover from ICT-related disruptions in a structured way. That affects system architecture, cloud strategy, internal governance, testing, incident response and the way provider contracts are drafted. A service outage, cyberattack or failed migration is no longer just a commercial headache. Depending on the circumstances, it can trigger reporting obligations, supervisory scrutiny and questions about whether the governance model was strong enough in the first place.
Contracts matter
FinTech contracts often carry more regulatory weight than ordinary agreements. FinTech agreements may look commercial on the surface, but they are often about allocating regulatory risk. In an agreement between a supervised party and e.g. a third-party supplier which is not supervised but a critical part of the supplier chain matters such as liability caps, indemnities, service levels, audit clauses, step-in rights, information rights and termination rights all become more material. If an infrastructure provider fails, the consequences may go far beyond the immediate contract. Delayed transactions, unavailable customer balances, broken authentication flows or missed regulatory reports can affect several parts of the ecosystem at once leading to responsibility and damages, regulatory sanctions, decrease in trust and more.
Consumer protection
Many FinTech products are aimed at consumers, even where there is a bank or another licensed partner in the background. This means the rules matter in very practical ways: how pricing is shown, how the product is marketed, what the customer sees before signing up, how complaints are handled and whether credit assessments are done properly.
The rules are becoming stricter. CCD2 is now in force at EU level and national implementation is ongoing. In Sweden, the separate consumer credit activities license has been removed, and it is now a criminal offence to start licensed or registrable activities without the right license or registration.
In FinTech, design choices are rarely just design choices. The way a repayment option is presented, the way fees are shown, or the way a user is pushed through an onboarding flow can all have legal consequences. A good interface can support compliance, but a persuasive one can also create risk if it hides who is responsible or what the user is agreeing to.
Where FinTech is heading
If the first phase of FinTech was about disruption, the current phase is more about maturity. One important development is the move from open banking to open finance. The basic idea is that access to customer data may extend beyond payment accounts to savings, investments, insurance and pensions. That creates room for new products, better comparison tools and more personalised
financial services, but it also raises harder questions about consent, access rights, liability and the practical governance of data sharing. The commercial opportunity is real, but so is the legal complexity.
Artificial Intelligence
Have you talked with someone about AI lately? AI is quickly becoming part of the sector’s basic infrastructure. It is already used in fraud detection, automated investing, customer support, credit scoring, onboarding and transaction monitoring. At the same time, AI is no longer just a technical or ethical issue. It is becoming a legal one as well, especially under the AI Act for businesses involved in higher-risk use cases. For FinTech companies, that means AI governance cannot be handled in isolation. It must fit with existing obligations under financial regulation, data protection, consumer protection and operational resilience. The businesses that handle this well are likely to be the ones that treat legal and technical design as part of the same exercise. Compliance can be a business opportunity, not just a burden.
Final thoughts
Taken together, these developments point in the same direction. FinTech is still associated with speed and innovation, but the market has become more regulated, more interconnected and less forgiving of weak legal foundations. The strongest companies are usually the ones that understand that early. They do not treat the legal framework as something to deal with later. They build products, partnerships and contracts that can work within it. That may sound less exciting than the usual rhetoric about disruption, but in practice it is often the difference between a business that scales and one that stalls.
