Islandbridge Capital

Islandbridge Capital began in 2008 from capital generated by successful entrepreneurs. Joseph McCarthy leads the firm as founder and chief investment officer alongside a small team of directors and portfolio managers. The firm allocates across private equity, private real estate and liquid markets. It executes buyouts and holds residential and mixed-use assets in the United Kingdom. Confirmed positions include Salt Meadows, Newgate Street Village and Halstead. Deployment occurs mainly in Europe with additional exposure through direct opportunities worldwide. Islandbridge Capital employs an independent team that handles wealth administration, custodian trades and opportunity sourcing. It maintains a Certified B Corporation designation since 2021. No recent operational events from the last 24 months appear in available records. The firm operates as a multi-family office that combines advisory services with aligned co-investments rather than managing external fund vehicles.
