Marc de Bruyn / Founder & Director
Legal depth, commercial context and a clear path forward.
Marc de Bruyn is the founder and director of MDB Law. He leads the firm’s work in financial services, banking law, regulatory and conduct risk, cross-border payments, OTC derivatives, payment services and crypto asset services.
His practice also extends to Family Office architecture, corporate and commercial work, litigation, family law and a broad range of private and business matters. His approach is to understand the decision behind the legal question, make the governing duties and risks clear, and build a practical route forward.
Marc holds BA Law and LLB degrees from Stellenbosch University, a Master’s degree in Banking Law from UNISA and an International Diploma in Financial Technology from Oxford.
MDB Law serves clients from Cape Town, Paarl and Pretoria, and works with established institutions, growing businesses, founders and families across South Africa.
The MDB Law approach
Legal architecture without confusing advice with implementation.
The MDB Stacks are structured legal products: a reusable regulatory core configured around the client’s actual business. They help teams see how authorisation, products, customer journeys, transactions, controls, governance and evidence fit together.
MDB Law provides legal interpretation, architecture, guided resources and critical review. The client remains responsible for its facts, business decisions, people, providers, implementation and day-to-day operation.
Work outside the Stack practice is available through MDB Law’s Family Office, Family Law and Diverse Legal Services practices and is assessed and scoped separately.
