Cargile Investment Management

William Cargile serves as the principal and primary decision-maker for the office. The firm maintains a lean internal structure, which keeps investment authority concentrated with the principal. External advisors and specialized consultants are engaged selectively for deal-specific diligence.

The office allocates across direct energy investments — including royalties and working interests with a natural gas emphasis — real estate holdings in Texas and the Mountain West, and private equity fund commitments. The private equity sleeve covers middle-market buyout, growth equity, and select venture capital funds, often with an industrial or energy services tilt.

The office does both. It makes direct investments in energy assets and real estate, while also committing to third-party private equity funds for exposure to buyout, growth equity, and venture strategies beyond its direct operating footprint.
