Key takeaways:
- Some of this is legally mandatory the moment you handle money or EU personal data: GDPR, DORA (if you qualify as an EU financial entity), and AML/KYC obligations don't wait for you to be ready.
- PCI DSS is a card network requirement enforced through your processor contract. It’s not a government law, but skipping it isn't really an option if you touch card data, since non-compliance can mean losing the ability to process cards at all.
- SOC 2 and ISO 27001 are not legal requirements, but a commercial expectation. For a FinTech partnering with banks or selling to enterprise customers, they are pretty much a prerequisite.
- The cheapest compliance decision most early-stage FinTechs can make is: minimize how much card and financial data you touch before building anything else.
FinTech compliance has a reputation for being uniquely painful, and there's a reason: it's one of the few startup categories where you're stacking general startup compliance (like SOC 2 and ISO 27001) on top of financial-sector-specific law (such as AML, licensing, and DORA) on top of a payment card industry standard that isn't law at all, but behaves like one.
This post maps the frameworks that matter for an early-stage FinTech, separates what's legally required from what's commercially expected, and gives a realistic priority order for tackling them.
GDPR: the baseline if you have EU users
If your FinTech has any EU users, GDPR applies to you.
Financial data is often sensitive enough that GDPR's requirements bite harder than they would for a typical SaaS product: transaction histories, income data, and credit information all carry higher stakes if mishandled.
The starting point is the same as any startup: a documented lawful basis for processing, a real privacy policy, and breach notification readiness.
Where FinTech-specific nuance comes in is data retention. Financial regulations in some cases require you to retain records longer than GDPR's general data minimization principle would otherwise suggest, and reconciling those two obligations is worth getting right early.
AML and KYC: the legal requirement founders often underestimate
If your product moves money, holds funds, or facilitates payments between parties, anti-money laundering (AML) and know-your-customer (KYC) obligations apply, and they are not something you ease into.
In the US, this runs through the Bank Secrecy Act (BSA). In the EU, through the Anti-Money Laundering Directives. These are legal obligations tied directly to your business model, with regulators that actively enforce them and penalties that can include criminal liability.
Many early-stage FinTechs operate under a bank partner's license (a Banking-as-a-Service arrangement) instead of obtaining their own, which shifts some, but not all, of this burden to the partner bank. Understanding exactly which AML/KYC obligations sit with you and your banking partner is an important conversation to have.
DORA: mandatory if you qualify
The Digital Operational Resilience Act has been fully applicable across the EU since January 17, 2025. It applies to a broad range of EU financial entities, such as payment institutions, e-money institutions, investment firms, crowdfunding platforms, and crypto-asset service providers among them, and, notably, to the critical ICT third-party providers those entities rely on, even when those providers are based outside the EU.
The question an early-stage FinTech should be asking: am I a "financial entity" under DORA's definition, or am I a technology vendor serving one? Plenty of early-stage FinTechs assume DORA doesn't apply to them because they're small, when the actual determinant is their regulatory status and activity, regardless of size. If you hold an EU payment institution or e-money license, or you're a crypto-asset service provider operating in the EU, assume DORA applies and verify from there.
Penalties for non-compliance are enforced by national regulators and vary by EU member state, since DORA doesn't centralize penalties the way GDPR does.
DORA's core requirements center on five areas: ICT risk management, incident reporting (major incidents require notification within hours of classification), digital operational resilience testing, third-party risk management (including a register of your ICT providers), and information sharing. For a lean startup team, the third-party risk management piece is often the heaviest lift, since it usually means renegotiating vendor contracts to include DORA-required terms.
PSD2: strong customer authentication for EU payments
If you provide payment services in the EU, like initiating payments, providing payment accounts, or acting as a payment gateway, the revised Payment Services Directive (PSD2) requires Strong Customer Authentication (SCA) for most electronic payments: two-factor verification combining something the user knows, has, or is.
This is a legal requirement, and it needs to be designed into your payment flow from the start.
PCI DSS: not a law, but not really optional either
PCI DSS occupies a strange middle ground.
It isn't really a government law. It's a security standard maintained by the Payment Card Industry Security Standards Council and enforced contractually through your acquiring bank or payment processor.
But the consequence of non-compliance is severe enough that it functions like a legal requirement: losing the ability to process card payments is close to an existential risk for a payments-adjacent FinTech.
One of the most effective compliance decisions most early-stage FinTechs can make is minimizing your Cardholder Data Environment (CDE) by using tokenization and hosted payment pages so that raw card data never touches your own systems.
A smaller CDE means a smaller PCI DSS audit scope, which is a cheaper problem to solve at the architecture stage. Check the penetration testing requirements specific to PCI DSS on PCI DSS Penetration Testing.
SOC 2 and ISO 27001: commercial requirements
Neither SOC 2 nor ISO 27001 is legally required. But for a FinTech, they tend to arrive earlier in the company's life than they would for a typical SaaS startup, because FinTechs frequently need a bank partner, a payment processor, or an enterprise customer before they can operate at all. All three of those relationships often demand a SOC 2 report or ISO 27001 certification as a condition of the partnership.
SOC 2 is the more common first ask for US-focused FinTechs, while ISO 27001 becomes relevant faster than usual if your bank partner, payment processor, or customer base is EU-based. Check the process for each of them in our SOC 2 compliance guide and What Is ISO 27001? posts.
Priority order for an early-stage FinTech
Given everything above, here's a realistic sequence, assuming you're building from scratch:
- Make the architectural decision on card data first. Before writing any payment-handling code, decide whether to keep raw card data out of your systems via tokenization and hosted payment pages. This decision determines how large your PCI DSS scope becomes later, and it's far cheaper to decide now than to retrofit.
- Confirm your AML/KYC and licensing exposure before launch, not after. If your product moves money, get a direct legal read on whether you need your own money transmitter licenses or whether your banking partner's license covers your activity. This is foundational to whether your business model is legal to operate as structured.
- Put GDPR fundamentals in place if you have any EU users. Lawful basis for processing, a real privacy policy, and breach notification readiness is the baseline every startup needs, with financial data's higher stakes in mind.
- Start SOC 2 (or ISO 27001, if EU-first) as soon as a bank partner or enterprise customer is in the conversation. For most FinTechs, this arrives earlier than expected, before the first funding round closes, because banking partnerships frequently require it upfront.
- Verify DORA’s applicability, don't assume your way out of it. If you hold or are pursuing an EU financial license, or you serve as an ICT vendor to entities that do, get a direct determination rather than assuming your stage exempts you.
- Layer in PSD2 SCA design if you're building EU payment flows. This needs to be part of your payment architecture from the beginning.

FAQ: Frequently asked questions
Is PCI DSS legally required for FinTech startups?
No, not by government law. It's a contractual requirement enforced by the Payment Card Industry Security Standards Council through your acquiring bank or payment processor. In practice, non-compliance can mean losing the ability to process card payments, which makes it functionally mandatory for any FinTech touching card data.
Does DORA apply to US-based FinTechs?
It can, if you serve as a critical ICT third-party provider to an EU financial entity, even without a physical EU presence. If you're US-based with no EU financial entity relationships, DORA doesn't directly apply, though GDPR may still apply if you have EU users.
Do we need SOC 2 before or after our first bank partnership?
Often before. Many banking-as-a-service partners and payment processors require a SOC 2 report as a condition of onboarding, which means it can arrive earlier in a FinTech's timeline than it would for a typical B2B SaaS company waiting for enterprise sales conversations.
What's the difference between DORA and GDPR for a FinTech?
GDPR governs how you handle personal data. DORA governs your operational resilience against ICT risk, like incident reporting, third-party risk management, and resilience testing. They overlap in places (a data breach can trigger obligations under both) but are separate regulations enforced by different mechanisms.
Is AML/KYC a security framework or a legal requirement?
It’s a legal requirement, not a security framework in the SOC 2 or ISO 27001 sense. It's tied directly to your business model under laws like the Bank Secrecy Act (US) or the Anti-Money Laundering Directives (EU), with regulatory enforcement and potential criminal liability for non-compliance, not just fines.
