Redbridge Capital

Redbridge Capital was founded in 2021 to manage the combined assets of the Susan McKinnon Foundation and the family office of Melbourne-based tech entrepreneur Grant Rule. The structure integrates philanthropic capital with family wealth under a single investment platform. The firm constructs portfolios across listed companies that sustain high returns on capital, listed equity funds run by concentrated fundamental managers, private equity and venture funds with thematic styles, direct co-investments and SPVs, and hedge funds that target uncorrelated returns with controlled volatility. Allocations target early-stage through growth opportunities in sectors including Energy Transition & Renewables, FinTech, Healthcare Services, and PropTech. Activity covers Asia, Europe, North America, the Middle East & Central Asia, and Oceania. Team leadership includes Grant Rule as founder, David Khaw as Chief Investment Officer, and portfolio managers Chen Lin, Stephen Rorie, and David Seebold. The firm maintains philanthropic vehicles including the Susan McKinnon Charitable Foundation and the Susan McKinnon Research Centre. It supports policy research through the Grattan Institute and the e61 Institute. Redbridge Capital integrates family-office capital with a dedicated philanthropic mandate, creating a governance model that aligns investment decisions with the Susan McKinnon Foundation's mission of long-term policy development and public-sector productivity.
