Prologue — The Year Fraud Redrew the Industry

On February 5, 2024, a finance employee at the Hong Kong office of UK engineering firm Arup transferred USD 25 million in 15 separate payments after a video conference attended by their CFO and several other executives. Every participant in the call was a deepfake. The real CFO was sitting in London.

When Hong Kong police disclosed the incident in May, the global security and finance community converged on the same conclusion.

Around the same time, other crises hit simultaneously.

The AI fraud and AML industry boomed in response. Visa announced a roughly USD 1B acquisition of Featurespace in September 2024, the EU AML Authority (AMLA) formally launched in Frankfurt, Korea’s FIU (Financial Intelligence Unit) added AI transaction monitoring requirements to the 2025 Specified Financial Information Act amendments, and Japan’s Mitsubishi UFJ Bank started a Hawk AI pilot in 2024.

This guide consolidates 70+ tools and regulations in one pass — modern fintech platforms, KYC, legacy AML, crypto, card payments, and deepfake detection.


1. Four 2024-2026 Shocks That Reshaped Fraud

A timeline of the events that bent the curve.

The message of these eight events is one thing. Fraud response in 2026 is no longer static rules — it is AI models, graphs, and deepfake detection running in concert.


2. Fraud vs AML — What Is the Difference

They look similar but operate on different axes.

Regulation differs too.

Platform-wise, the two are converging. Sardine, Unit21, Hawk AI, Feedzai, and Featurespace all market themselves as "Fraud + AML integrated platforms" because pulling both signal classes from the same transaction stream is more efficient.

[Fraud vs AML signal differences]
  Fraud
    - Behavioral anomalies (unusual time, device, geo)
    - Card / account identity mismatch
    - Velocity anomalies
    - Amount anomalies vs baseline

  AML
    - Pattern anomalies (stratification, smurfing, layering)
    - High-risk jurisdiction / sanctioned counterparties
    - PEP (Politically Exposed Persons) transactions
    - Cash / crypto conversion patterns
    - Unusual corporate structures (shell companies)

3. Why AI — The Limits of Rules

The reasons AI/ML adoption accelerated in fraud and AML.

The core point: AI does not replace analysts. It improves the quality of the queue analysts see. US FinCEN’s 2025 guidance also emphasizes model risk management (MRM) and explainability (XAI).


4. Sardine — Fraud + AML for Modern Fintech

Sardine (sardine.ai) was founded in 2020 by Soups Ranjan (former Head of Fraud at Coinbase), Aditya Goel, and Jose Marques.

The differentiator is design philosophy: catch fraud signals at the moment of payment, then reuse the same signals for AML rules. Sardine raised about USD 70M in Series B and added a Series C in 2024. Fast API onboarding and fintech-friendly pricing drove rapid US, EU, and Asia fintech adoption.


5. Unit21 — Fraud + Compliance Ops Platform

Unit21 (unit21.ai) was founded in 2018 by Trisha Kothari and Clarence Chio, a Y Combinator alum.

Unit21’s strength is a UI built "by analysts for analysts," a reflection of Kothari’s own time running fraud ops at Affirm. Series C raised about USD 45M in 2024.

Where legacy enterprise solutions like NICE Actimize and SAS run 5-10 year deployment cycles, Unit21 targets 3-6 months to production.


6. Hawk AI — Munich-Born Transaction Monitoring

Hawk AI (hawk.ai) was founded in 2018 in Munich, Germany, by Tobias Schweiger and Wolfgang Berner.

Hawk AI’s architecture is squarely aimed at EU 6AMLD and the upcoming 7AMLD. The 2024 Series C raised USD 56M, led by Sands Capital. The Mitsubishi UFJ pilot is its flagship Asia entry.


7. ComplyAdvantage — Sanctions, Adverse Media, AML

ComplyAdvantage (complyadvantage.com) was founded in London in 2014 by Charles Delingpole.

The differentiator is NLP-driven classification of global adverse media at scale, mining millions of news items daily and matching them to risk subjects. Goldman Sachs led the 2022 Series D for USD 70M.

Korea and Japan footprints are limited, but global fintechs frequently standardize on ComplyAdvantage.


8. Featurespace — The ARIC Engine Visa Bought

Featurespace (featurespace.com) was founded in 2008 in Cambridge, UK, by David Excell out of the University of Cambridge engineering department.

Visa’s acquisition sends a clear industry signal. Card networks are bringing fraud AI in-house. Mastercard had already acquired Brighterion in 2017 and bought Recorded Future for USD 3B in 2024 to bulk up its fraud intelligence.


9. Feedzai — Portugal’s Integrated Risk Platform

Feedzai (feedzai.com) was founded in Coimbra, Portugal in 2011 by Nuno Sebastião, Paulo Marques, and Pedro Bizarro.

Feedzai targets large global banks head-on as the modern alternative to NICE Actimize, SAS, and Oracle FCCM.


10. Quantexa — Entity Resolution Champion

Quantexa (quantexa.com) was founded in London in 2016 by Vishal Marria.

The essence of money laundering is hiding identity behind legal entities. Quantexa’s edge is stitching together company registries, news, and internal data across dozens of countries to expose the ultimate beneficial owner (UBO). Demand has surged alongside EU AMLR’s UBO registry mandates.


11. Sentinels (Forter Acquired) — Fraud + AML Convergence

Sentinels (sentinels.ai) is a Dutch AML startup founded in Amsterdam in 2019. Payments fraud specialist Forter acquired it in November 2024.

The deal is a clear signal. The line between fraud and AML is collapsing fast.


12. Sumsub — Global Identity Verification Standard

Sumsub (sumsub.com) was founded in 2015 by Andrew Sever, Jacob Sever, and Peter Sever, headquartered in London.

Sumsub’s distinctive value is bundling liveness, document OCR, and AML screening in a single SDK. Korea and Japan expansion is active — Korean crypto exchanges including Bithumb have partial deployments.


13. Persona — Onboarding + Verification Orchestration

Persona (withpersona.com) was founded in San Francisco in 2018 by Rick Song and Charles Yeh.

Persona’s strength: compliance teams can edit workflows without writing code. Series D in 2022 raised USD 150M at roughly USD 1.5B valuation.


14. Alloy — KYC Orchestration Hub

Alloy (alloy.com) was founded in New York in 2015 by Tommy Nicholas, Laura Spiekerman, and Charles Hearn.

Alloy’s positioning is different from peer KYC vendors. Alloy itself does not perform KYC — it orchestrates and routes across many KYC data sources. Some call it "the Plaid of KYC." Series C in 2022 raised USD 100M at roughly USD 1.5B valuation.


15. Onfido, Jumio, Veriff — The Document + Selfie Trio

The three global heavyweights of document plus selfie verification.

All three center on liveness (proving a real person is present) plus document verification. Liveness v2 or v3 deepfake-resistant releases shipped from 2024 onward.


16. Trulioo, Socure, iProov — Global, US, Biometric

Three complementary categories.

Other relevant names: Yoti (UK, digital ID and age verification), FaceTec (US, 3D face liveness), and Daon (US/Ireland, multimodal biometrics).


17. Legacy + Enterprise AML — NICE Actimize, SAS, Oracle FCCM

The large global bank market is still dominated by four legacy incumbents.

Also in the conversation: NetReveal (BAE Systems Applied Intelligence), FICO Tonbeller (Siron), LexisNexis Risk Solutions, and Refinitiv World-Check (LSEG). Deployment cycles are long (5-10 years) and license costs start in the millions of USD.


18. Chainalysis, TRM Labs, Elliptic — Crypto AML Trio

The more crypto institutionalizes, the more blockchain analytics explodes.

The biggest 2024 moment: tracking North Korea Lazarus’ USD 1.4B in stolen funds. Chainalysis and TRM Labs jointly visualized flows, leading to OFAC sanctions actions.


19. Card + Payment Fraud — Stripe, Adyen, Riskified, Forter, Signifyd, Sift, Kount

Tools built for payment processors and e-commerce.

Chargeback guarantees let e-commerce outsource fraud risk. Synthetic identity fraud rose in 2024, so verification rigor at these vendors rose with it.


20. Deepfake + Voice Fraud — Pindrop, Daon, Reality Defender, Sensity, Truepic

The fastest-growing category after the Arup incident.

Call center fraud surged in 2024-2025. Per Pindrop’s report, AI voice synthesis attempts against contact centers grew roughly 4x in 2024 alone.


21. Synthetic Identity — TransUnion, Experian, LexisNexis, Equifax

In the US, synthetic identity is among the largest threats.

Defensive tools:

The key capability is verifying identity consistency across time. A synthetic identity shares an SSN with a real person but disagrees with their other data points.


22. Instant Payment Fraud — FedNow, UK Faster Payments, EU SCT Inst, Korea, Japan

As 24/7 instant payments become the norm, fraud response windows shrink to minutes.

The AML challenge with instant payments: transfers cannot be reversed. If you cannot determine fraud in five seconds, the money is gone permanently. Hawk AI, Featurespace, and peers stress real-time models tuned to this five-second window.


23. Regulatory Frameworks — FATF, BSA, EU AMLA, Korea, Japan

The core regimes by region.

Global

United States

European Union

EU payment regulation

Korea

Japan


24. Korea Fraud + AML Stack

The Korean market blends card issuer in-house FDS, internet-only banks, and government systems.

Korea’s voice phishing losses are estimated around KRW 550B annually in 2024. From 2024-2025 the government strengthened a joint response system spanning telcos, banks, and easy-pay providers.


25. Japan Fraud + AML Stack

The Japanese market blends SIer-led platforms with megabank adoption of global tooling.

Japan received a "Largely Compliant" rating in the FATF mutual evaluation in August 2024, with extra strengthening flagged in the virtual asset domain. From 2025 the FSA explicitly added AI transaction monitoring to its guidelines.


26. Major 2024 Fraud + AML Incidents

Representative cases.

The common thread: AI was weaponized by attackers and operationalized by defenders simultaneously.


27. AI for AML — GNN, NLP, Generative AI

AI techniques applied across AML operations.

The EU AI Act classifies AML AI as a "high-risk AI system," requiring explainability, model risk management, and audit logs.


28. Vendor Selection Guide — Who Should Pick What


29. Five-Year Outlook — Where We Are Headed

Five trends.


30. Conclusion — AI Is Both Weapon and Shield

The 2026 fraud industry lives with two truths at once.

The core message: fraud response is no longer a compliance back office — it is a core function deeply integrated with product, payment, and UX. The 2026 fintech edge is the balance between determining fraud within five seconds and minimizing friction for legitimate users.

Analysts, developers, and compliance leads now look at the same data with the same tools. You do not need to know 70 tools — you do need to know exactly where your business sits.
