ARRIEN INVESTMENTS, INC.

ARRIEN INVESTMENTS was established as a single-family office vehicle for Michael Arriens, though the firm does not publicly disclose wealth origin or founding year. The entity operates from Los Angeles with a lean, direct-deal focus that avoids commingled fund structures. Investment strategy centers on two pillars: direct real estate acquisitions—multifamily, industrial, and office in select Sun Belt markets—and private credit origination, including senior secured loans to middle-market companies. The firm also considers infrastructure and energy transition opportunities, though no specific portfolio companies are confirmed (per public record). Geographic scope remains U.S.-focused, with no disclosed international exposure. No recent personnel count or AUM figures are publicly available. The firm maintains no discernible philanthropic foundation or adjacent vehicles. There is no verifiable operational event from the last 24 months in the public domain (Altss estimate). ARRIEN INVESTMENTS' structural differentiator is its outright avoidance of fund structures—the firm deploys only proprietary balance sheet capital directly, removing GP-LP friction. This model trades scalability for control and alignment, a deliberate choice for a single-family office managing undisclosed capital.
