The best custom RegTech AML/KYC software development companies are Dreamix, Netguru, Intellectsoft, ELEKS, and Andersen. Other top options include 10Clouds, Vention, Softermii, Innowise, Yalantis, and Itransition.
Building AML and KYC systems means handling onboarding, risk scoring, and reporting in ways that fit an organization’s own infrastructure and processes. Custom software development addresses that by building compliance tools around a company’s own workflows and requirements. Finding the right development partner for that work matters as much as the build itself. The list below doesn’t rank companies by revenue, size, or client volume; it focuses on experience and fit for AML and KYC work.
10 Custom RegTech Development Companies Specializing in AML/KYC
Selection criteria centered on five factors:
- Proven experience in regulated financial industries
- Technical depth in AI and data engineering for risk detection
- A track record of secure and auditable system design
- The ability to integrate new tools into a client’s existing tech stack
- A delivery model built for long-term partnership rather than one-off projects
Companies that primarily sell fixed, pre-built compliance products were left off this list, since the focus here is custom engineering.

1. Dreamix
Best for: Enterprises modernizing legacy systems in aviation, fintech, healthcare, and RegTech
Dreamix is an AI-native custom software engineering company with close to two decades of experience building for regulated industries. Its core focus areas include custom software development, data engineering, agentic AI, and legacy system modernization, with deep experience across aviation, fintech, healthcare, and RegTech, including AML, KYC, and KYB workflows. In 2024, Synechron, a global digital transformation consulting firm, acquired Dreamix, which strengthened its delivery capacity and client reach in financial services.
The company builds AML and KYC systems that integrate directly with a client’s existing infrastructure rather than replacing it outright. This approach suits organizations that need custom risk-scoring logic, automated identity verification, or agentic AI workflows layered onto systems already in production.
2. Netguru
Best for: Fintech startups and scaleups
Netguru, headquartered in Poland, has built a strong fintech portfolio over the years. The company develops custom compliance tools and digital banking solutions for clients who need to move quickly without sacrificing regulatory rigor. Its teams work closely with product owners at early-stage and growth-stage fintechs, which makes it a fit for companies still shaping their compliance architecture.
3. Intellectsoft
Best for: Large enterprises
Intellectsoft, based in the United Kingdom, focuses on enterprise-grade custom development with specific expertise in banking and financial services. The company handles large, multi-team engagements where compliance systems need to connect with broader enterprise architecture. Its experience with complex stakeholder environments makes it a reasonable choice for organizations running large-scale digital transformation programs.
4. ELEKS
Best for: Banks and enterprise fintech
ELEKS operates out of Ukraine and brings extensive financial software experience to AML and KYC projects. The company combines AI, analytics, and compliance system development, which suits banks that need custom fraud detection or transaction monitoring built around existing risk models. ELEKS also works with enterprise fintech clients that require deep integration with legacy banking infrastructure.
5. Andersen
Best for: Large custom compliance platforms
Andersen runs a large engineering team across Poland and other parts of Europe, with specific expertise in AML, banking, and payment systems. The company’s scale supports large, multi-phase compliance platform builds that require sustained engineering capacity over time. Organizations building comprehensive compliance infrastructure from the ground up often look to Andersen for that reason.
6. 10Clouds
Best for: Fintech and Web3
10Clouds, based in Poland, specializes in fintech and blockchain projects, including KYC onboarding flows for regulated products. The company’s experience spans traditional fintech and Web3, which gives it a specific advantage for clients building identity verification into decentralized or crypto-adjacent platforms. Its onboarding-focused work suits companies that need smooth, compliant user verification at the front end of their product.
7. Vention
Best for: Scaleups needing dedicated teams
Vention operates through European delivery centers and builds financial software with compliance integrations and secure architectures. The company works well with scaleups that need a dedicated, embedded engineering team rather than a fixed-scope project. Its delivery model favors organizations that want ongoing collaboration as compliance requirements evolve.
8. Softermii
Best for: Mid-market fintech companies
Softermii, headquartered in Ukraine, has experience across fintech, identity verification, payment platforms, and AML workflows. The company’s client base tends to sit in the mid-market range, where budgets are tighter but compliance requirements remain just as strict as at larger firms. Softermii’s identity verification work in particular makes it relevant for KYC-focused engagements.
9. Yalantis
Best for: Custom financial platforms
Yalantis, headquartered in Ukraine, has built a strong financial services portfolio centered on secure, compliance-oriented development. The company works on custom financial platforms where security architecture and regulatory alignment need to be built in from the start. This makes Yalantis a fit for organizations building new compliance-heavy products rather than retrofitting existing ones.
10. Itransition
Best for: Large digital transformation projects
Itransition works through European delivery teams and brings enterprise software engineering experience in banking, risk management, and regulatory compliance.
The company handles large digital transformation projects where AML and KYC systems are one part of a broader modernization effort. Its risk management background adds useful context for clients dealing with complex, multi-system compliance environments.
Choosing the Right Partner
The right development partner depends on the scale of the project, the existing technology stack, and how much ongoing support the compliance system will need. Smaller fintechs often benefit from teams used to fast iteration, while large banks tend to need partners comfortable with complex, multi-system integrations.
Whichever company a business chooses, the priority stays the same: a compliance system built to fit real infrastructure, not one built to replace it.
