4-D Investments LLC

4-D Investments LLC is a family office founded by James H. Jacobson, based in West Jordan, Utah. The firm manages capital for the Jacobson family, with wealth origin tied to estate planning and investment management. It operates as a single-family office, maintaining discretion typical of smaller family offices in the region. The strategy spans multiple asset classes including real estate, private equity, and venture capital, with a likely focus on direct investments and co-investments alongside trusted partners. The firm targets opportunities primarily in the Intermountain West and broader US markets. Known portfolio holdings or deals are not publicly disclosed. The firm is lean — no publicly listed team size or additional offices. 4-D Investments does not maintain a prominent website or social media presence. There is no verifiable recent operational event from the last 24 months. It likely operates as a closed vehicle for the immediate family. 4-D Investments’ key differentiator is its low public profile — the firm does not market itself as a multi-family office or institutional asset manager. It functions as a classic single-family office, prioritizing wealth preservation and confidentiality over external fundraising or brand-building.
