What to expect
B2B only. Compliant by design.
We are not a bank and we do not provide investment advice. We apply KYC/AML and sanctions screening appropriate to the engagement. We maintain audit-ready files and limit data collection to what is necessary to deliver the mandate.
Anti-bribery and corruption: zero tolerance. We follow a simple gifts & hospitality policy and decline facilitation payments. We protect operational data and share it strictly on a need-to-know basis.
