The art
of finance

Where investments
become masterpieces.

About Us

We are a global and coordinated solution for every aspect of your wealth: tax, legal, administrative, and investment-related. Our value proposition is to partner with you in advising and managing your wealth—both liquid and illiquid assets. This is an independent advisory relationship: one618 Wealth Management provides guidance on your investments, which are held in your name at top-tier banks of your choice.

Our team of professionals conducts a comprehensive assessment of your financial position, considering your current family situation, liquidity needs, expected returns, and risk profile. Based on this information, we develop tailored recommendations and provide ongoing monitoring and support.

Trusted advisors focused on preserving our clients'
greatest asset: peace of mind.

There are no conflicts of interest in our approach—because we invest alongside you. That's why we don't see you as a client, but as a partner. And together, we have much to gain.

Above all, we are committed to absolute confidentiality. Every inquiry is handled under strict professional secrecy, and all information related to your assets is subject to rigorous control protocols, jointly defined with each client.

one618 Wealth Management operates under the same model as American family offices: a team of professionals working on your behalf, representing your interests before third parties—banks, brokers, fund managers, and other institutions.
