About ROZSUD
Advice shaped by experience inside regulated businesses.
ROZSUD is an international legal and regulatory advisory firm helping businesses in regulated and high-risk digital markets launch, get paid and grow across borders.
Our team brings practical experience in licensing, AML, payments, corporate structuring, information security and legal operations — gained not only advising on regulatory requirements but implementing them inside operating companies. The result is advice built to be put into practice.
Why ROZSUD
Regulation rarely sits in one department.
A licensing decision affects corporate structure. Corporate structure affects banking and payments. AML requirements affect onboarding, product and operations. Information-security and privacy requirements affect technology, vendors and customer relationships.
ROZSUD advises across those intersections: one team coordinates legal, regulatory, compliance and governance work from structure through implementation, so that decisions in one area are taken with their effect on the others in view.
Approach
How we work
Senior-led
Clients work directly with the professionals responsible for the strategy and execution of their matter.
Commercially grounded
We consider how regulatory decisions affect product, payments, operations and expansion — not only what the law says in isolation.
Direct about risk
We distinguish between what is legally possible, what can be defended before a regulator and what regulators, banks, payment providers and other counterparties are likely to accept — so you invest in routes that can work.
Scoped before work begins
Work, responsibilities, dependencies and commercial terms are agreed before execution starts, so you know what you will receive and on what terms.
Team
The people behind the work.
ROZSUD combines legal, regulatory, financial crime, information security, privacy, AI governance and commercial expertise, brought together on each matter rather than split between separate advisers.
Valerii Matiash
Founder & Managing Director
Legal, Regulatory & AML
- Qualified Advocate
- CAMS
- Master of Laws
Valerii leads ROZSUD's legal and regulatory practice. He advises gaming, fintech, payments, crypto and other digital businesses on licensing, market entry, AML/CFT, payments, cross-border structuring, commercial arrangements and day-to-day regulatory risk.
His background combines private practice, in-house leadership and advisory work. He has built legal and AML functions from the ground up, led multi-jurisdictional licensing projects, developed AML/KYC/KYB and sanctions frameworks, and structured international corporate and payment infrastructure.
At ROZSUD, his focus is on the decisions that define the regulatory architecture of a business: where and how it should be structured, which licences or regulatory permissions it requires, how financial-crime and operational risks should be managed, and how those decisions affect payments, banking, product design and market expansion.
He remains directly involved in complex matters where legal, compliance, regulatory and commercial considerations cannot be separated.
