Harbor Ithaka
Harbor Ithaka began in 2006 when Carlos J. Arredondo established the firm to deliver macro research and risk consulting to Latin American ultra-high-net-worth families. It later expanded into a full multi-family office platform that combines portfolio construction, alternative access, and ongoing monitoring. The firm allocates across real estate, private credit, infrastructure, hedge funds, secondaries, and digital assets. It deploys capital through fund-of-funds structures and segregated portfolio vehicles, including the Harbor Ithaka Tactical Select Allocation Real Estate SP and the Harbor Ithaka Life Settlements Multi Strategy Fund SP. Activity spans North America and South America. No individual external portfolio companies are disclosed in available records. The team includes Rafael Alcantara-Lansberg as CIO and Javier Miñana Alonso as business partner. Operations are housed under parent Harbor Financial Holdings LLC. No dated operational events from the last 24 months appear in public sources.
