Raising capital is just one part of the equation. For fintech founders in 2025, the real challenge lies in building products that are not only fast and secure, but also AI-native and regulatory-ready from day one. Between €5.2 and €6.3 billion has already flowed into European fintech startups this year, while U.S. firms continue to attract the lion’s share globally, capturing 60 % of all fintech investment and 71 % of mega-round funding in Q2 alone. The funding is returning, but so are the expectations.The funding is returning, while but so are the expectations.

Investors are doubling down on fintechs that solve real operational problems in regulated industries, utilize artificial intelligence intentionally, and embed compliance directly into their platforms. From wealth management to insurtech, the signal is clear: product-market fit in fintech now depends on getting the architecture right early.

Today, we’re taking a look at the momentum across Europe and the US, connecting three essential themes founders need to build around today: AI, capital, and compliance.

1. Capital is back, but traction matters more than hype

After a cautious few years, investor sentiment in fintech has shifted firmly back into growth mode. In Europe, Berlin, Milan, and Paris emerging as key hubs thanks to deep capital access and supportive regulatory frameworks (SeedBlink), while in the U.S. the 3 key players remain San Francisco / Silicon Valley, New York and Austin (JPMorganWorkplace).

But while the volume of funding may feel familiar, the nature of investor interest has evolved. Capital is no longer chasing generalist fintechs with broad, loosely defined ambitions. Instead, it is flowing toward companies with clear vertical specialization, defensible tech infrastructure, and demonstrable regulatory readiness from the outset.

Recent funding rounds illustrate this shift in priorities:

• Kalshi (US) raised $300 million in Series D to scale a predictive market platform focused on regulated event-based trading (AlleyWatch).
• Resistant AI (EU) secured €25 million in Series B to expand its AI tools that detect fraud and financial crime across fintech ecosystems (Tech.eu).
• Bezahl.de (Germany) closed a €23 million Series C to strengthen its foothold in European digital payments, a space where infrastructure and compliance are tightly linked (Vestbee).

Early-stage rounds are showing a similar pattern. Seed and Series A funding is going to startups building in complex, compliance-heavy spaces (AI-driven tax tools, freelance economy infrastructure, and finance platforms for industrial sectors) where domain depth matters more than speed to market.

This signals a shift in how traction is assessed. It is no longer enough to show active users or top-line growth. The startups attracting serious investment are those that can demonstrate:

• A robust path to regulatory alignment
• A well-articulated AI strategy that goes beyond surface-level automation
• Deep integration into the workflows of niche, underserved markets

In other words, capital is returning, but it's going to startups that can demonstrate long-term viability through product integrity and operational depth. At the core of that depth is a clear, intentional use of AI. 

Now let's see how AI is becoming the structural foundation for fintech maturity, and what that means for how products are designed, built, and scaled.

2. AI isn't a feature; it's the infrastructure

For many fintech founders, the first encounter with AI happens through automation: fraud detection, credit scoring, chatbot support. But in 2025, these use cases are the baseline. Investors and partners are now looking at AI as part of the infrastructure, something that shapes the product, not just enhances it.

This shift is evident in how capital is being distributed. Startups that bake AI into their architecture from day one are commanding larger rounds and more strategic backing. In Europe, Mistral AI’s €1.7 billion Series C is a headline example, funding large language models and enterprise-grade AI agents that are directly applicable to data-sensitive industries like banking and insurance (Mistral AI).

But the trend is not just about scale. Mid-stage companies like Light (Copenhagen) and Kertos (Munich) are gaining traction for their AI-native platforms targeting financial operations and compliance, respectively. Their approach reflects a broader move toward systems that don’t simply support finance workflows, but actively learn from them, improving over time without manual rule setting.

For early-stage fintech founders, this evolution raises a critical question: is AI part of the product’s core loop, or just a tool layered on top? As explored in our piece on why fintech scaleups start with AI PoCs rather than full platform rewrites, the implementation path matters as much as the AI strategy itself.

AI infrastructure unlocks three distinct advantages for fintech builders:

• Adaptability: Products can adjust to new data patterns, risk signals, or user behaviors in real time, without requiring full re-engineering.
• Regulatory alignment: With AI-powered audit trails and pattern recognition, compliance becomes a product capability, not just an operational burden.
• Efficiency at scale: The more the system learns, the more it reduces manual overhead, especially in functions like underwriting, claims processing, and KYC.

These are no longer future-facing benefits. They are becoming table stakes in categories like insurtech, payments, and B2B finance.

Yet technical capability alone isn’t enough. The real competitive edge comes when fintech products embed this intelligence into vertical workflows, tailored to the specific constraints and opportunities of each industry. That’s where domain specialization becomes the next defining factor.

3. Specialization is the strategy

As AI becomes foundational, the differentiation for fintech startups increasingly lies in where and how that intelligence is applied. Broad, one-size-fits-all platforms are giving way to vertical solutions, products built around the nuances of specific sectors, user types, or transaction models.

This movement toward specialization isn’t just a market trend. It reflects a deeper alignment between technical capacity and operational relevance. Fintechs gaining traction in 2025 are those that don’t just serve a financial function, but embed themselves into the workflows of industries with complex regulatory or operational requirements.

Take Nelly, a Berlin-based insurtech automating claims processing using AI, which grew its team by over 70 percent this year to keep up with demand in Europe’s tightly regulated insurance market (Omnius.so). Or Lexroom.ai in Milan, which secured €16.2 million to expand its legaltech tools, helping law firms manage compliance and documentation at scale through intelligent automation (Vestbee).

Other examples include:

• Shakers (Spain), building AI-driven infrastructure for the freelance economy.
• Insify (Netherlands), offering digital insurance tailored to freelancers and SMEs.
• Filed (UK), using AI to simplify and scale tax compliance.

These are not horizontal platforms chasing market share; they’re purpose-built systems that solve real, high-friction problems in niche segments. The most resilient fintechs are those that go deep into sector-specific challenges rather than broad across loosely defined markets.

This model introduces new demands on product development. It requires not just technical precision, but contextual fluency, understanding the daily realities of logistics managers, HR leads, legal partners, or SME accountants, and then designing tools that feel native to their environment.

What ties these vertical fintechs together is not just what they build, but how they integrate AI and compliance into the core value proposition. That integration creates not only a better product, but a stronger position when it comes to navigating evolving regulatory requirements, something we'll unpack next.

4. Compliance is now a product requirement

As fintech products move deeper into regulated industries, compliance can no longer be treated as a backend function or a phase-two priority. For investors, partners, and end users alike, regulatory readiness is fast becoming a test of product credibility and a key predictor of a startup’s scalability.

Across Europe, regulatory frameworks are adapting to support this evolution. The EU’s Digital Finance Platform and updated crowdfunding regulations are examples of policies designed to help startups bring innovative financial services to market while maintaining legal alignment (EU Startups). This creates both opportunity and pressure: founders now have more pathways to compliance, but far less room for oversight.

The smartest fintechs are building compliance into the product from day one. AI is helping make this possible. Tools like Kertos (Germany), which raised €14 million for its AI-powered compliance platform for SMEs, are showing how regulation itself can be treated as code: monitored, enforced, and adapted in real time through intelligent systems.

This has practical implications across the product lifecycle:

• Design: Products must account for jurisdiction-specific data handling, identity verification, and transaction logging from the outset.
• Build: Modular architecture enables teams to implement updates quickly in response to shifting compliance rules without reworking core systems.
• Operate: Real-time auditability, automated reporting, and transparent decision logic are no longer optional; they are baseline expectations.

Beyond functional requirements, regulatory alignment is also becoming a trust signal. In a crowded market, startups that can demonstrate compliance readiness from the earliest stages are far more likely to win enterprise partnerships, secure institutional clients, and accelerate their time to market.

This reinforces a broader theme: fintech success in 2025 is defined not just by innovation, but by execution under constraint. The most compelling products are those that can scale in tightly regulated environments, powered by AI and grounded in a deep understanding of their vertical.

What emerges is a new kind of competitive edge, less about speed to launch, more about the structural quality of what’s being built. Let’s bring that together.

5. Building for resilience, not just velocity

Across funding trends, AI integration, vertical specialization, and compliance alignment, a clear pattern is emerging: the most successful fintech startups in 2025 are not the ones moving the fastest, they’re the ones building with structural resilience from day one.

This shift redefines what early traction looks like. It’s not just about acquiring users or releasing features. Investors and partners are now calibrating value based on how well a product aligns with real-world constraints (regulatory, operational, or sector-specific) and how intelligently it can scale within them.

This means rethinking core assumptions:

• Speed is important, but durability wins. Fast MVPs that ignore compliance or architectural depth will need expensive rewrites later.
• AI is not a differentiator unless it’s embedded. Surface-level automation isn’t enough. AI must drive meaningful outcomes: risk detection, financial forecasting, or decision logic that adapts over time.
• Compliance is not a blocker; it’s a design opportunity. Founders who treat regulation as a product constraint early can turn it into a competitive advantage.
• Specialization narrows the target, but deepens impact. Fintechs built for specific user groups or industries scale more efficiently and defensibly than broad horizontal platforms.

The return of capital is an opportunity, but only for teams building with clarity and purpose. In 2025, product-market fit in fintech means more than demand. It means depth, defensibility, and the ability to operate inside complexity without losing speed.

For fintech founders navigating this next phase, the challenge isn’t just to build quickly. It’s to build with foresight, aligning product architecture, compliance frameworks, and AI capabilities in ways that compound over time.
