The Team

Built on capital markets experience.

Founding Partner, Managing Principal

Matheus Simoes

Serious capital deserves serious care.

Matheus Simoes is the founder of Lumen Capital. He built the firm on a single conviction: that serious capital deserves serious care, and that what protects wealth across decades is rarely the next opportunity. It is structure, governance, and clarity.

He leads the firm's cross-border work between the United States and Latin America, across structured credit, private market investments, capital advisory, and financial engineering. His focus is to align each structure to the counterparty's mandate, risk parameters, and horizon, rather than fitting a counterparty to a product.

Based in Miami, he works with qualified investors, family offices, and institutional counterparties for whom documentation discipline and discretion are not negotiable.

Lumen Capital is supported by an extended network of qualified counsel, audit and tax advisors, and execution partners. Each engagement is staffed and resourced according to its specific requirements.

Trajectory

From engineering to international finance.

Matheus Simoes built his career in financial markets between Brazil and the United States. Daily contact with sophisticated clients revealed a demand that went beyond any single product: international structure, accounts across jurisdictions, and access to transactions with governance. He founded Lumen Capital to serve that demand completely and independently.
