Principal Invest

Principal Invest

Principal Invest was established in 2015 by Justin Epstein to handle the investment activities of a single family office. Epstein had earlier founded One Investment Group and served as Investment Director at LJCB Investment Group. The firm maintains its headquarters in Sydney and reports no additional offices. The portfolio spans listed equities, private equity, property, senior debt, structured credit and hedge funds. Investments occur through direct holdings and co-investments with external partners. Confirmed positions include Star Car Wash in Australia and prior aircraft leasing assets managed under Global Aviation Asset Management. Geographic exposure covers Asia, Europe, the Middle East, North America, Oceania and South America. The firm avoids startup-stage venture investments. Justin Epstein and Greg Wang serve as the two named principals. Epstein has deployed more than $1 billion across asset classes over fifteen years. Wang brings twenty years of private equity and corporate finance experience, including more than $100 million invested and prior roles at EY and Caliburn. The Sydney office monitors performance and supports allocation decisions. No dated operational events from the past twenty-four months appear in public records. The structure centers on discretionary capital from one family office rather than external fundraises or third-party mandates. This setup allows direct execution across public and private markets without the reporting layers typical of multi-client platforms.
