Built on
conviction.
RADIANX CAPITAL was founded on a simple belief: that high-net-worth individuals deserve the same caliber of investment management and financial counsel previously reserved for the largest institutional investors.
A firm built for
the long term
Founded in New York in November 2017, RADIANX CAPITAL was established to close the gap between institutional investment management and private wealth — bringing genuine analytical rigor, transparent pricing, and unwavering fiduciary commitment to discerning clients.
Over eight years, we have grown to manage nearly $1 billion in assets while maintaining the operational discipline, selectivity, and personal attention that define who we are. Our clients are not account numbers — they are long-term partners.
We are registered with the SEC (No. 801-117100), held to the highest regulatory standards, and bound by an absolute fiduciary duty to every client we serve.
Our core
principles
These principles are not aspirational statements posted on a wall. They are the operational standards by which every client relationship, every investment decision, and every internal process is conducted.
The people
behind your capital

Eight years
of measured growth
From founding to nearly $1 billion under management — a progression built on trust, not marketing. Each milestone reflects a deepening of client relationships, not a departure from them.
