Biography
Thirty years of building,
investing & leading
Justin Peter Gardiner Lowe, known professionally as Justin Lowe, is an American-Swiss investor and the founder of Gardiner Investments, a family office working between Miami and Geneva. Its present focus is the metals the energy transition and Western supply chains depend on, alongside technology and financial technology, with positions taken across Latin America, Africa, the Balkans and North America. He has spent his career in global capital markets, investment banking and asset management, as an investor and as a founder.
He began investing in hedge funds in 1999 and co-founded Reliance Management, a leading fund of hedge funds manager that grew beyond $2 billion in assets under management by 2008. In 2010 Reliance acquired the New York-based Pan Funds to form Pan Reliance Capital Advisors, which won Sustained Excellence in Funds of Hedge Funds Management in 2014 and Fund of Hedge Funds Adviser of the Year in 2013 and 2017.
He founded Gardiner Investments in 2015 to manage family assets, exiting Pan Reliance three years later. He is Chairman of Saddleback Uranium and Chairman of the Advisory Board of PSG Digital.
His first novel, Since Ninety-One, is a work of geopolitical fiction. Four lives converge on a negotiating room in Geneva, and the question running beneath them is how the world arrived where it is from the hope that followed the end of the Cold War. It is available now on Amazon. His second novel, The Unlit, is in progress. It explores how humanity might hand its future to artificial intelligence, not through conquest but through a series of sensible, well-intended decisions, and asks what freedom, work and meaning become when the most capable mind on earth no longer needs us.

Heritage
The Gardiner Legacy
Justin carries forward a transatlantic lineage spanning finance, diplomacy and public service. That inheritance shapes the values he brings to his own work: stewardship, integrity and a preference for institutions built to last.
The Gardiner family arrived in America in 1638, among the founding settlers of colonial Rhode Island. The line's most prominent eighteenth-century figure was Sylvester Gardiner (1708–1786), the Boston physician and land proprietor whose grants gave the town of Gardiner, Maine its name. Justin is the great-grandson of Robert Hallowell Gardiner IV, who founded the Fiduciary Trust Company in Boston in 1928, a landmark institution in American wealth management. Through the Gardiner line he inherits a tradition of fiduciary responsibility and long-horizon thinking that still informs his approach to investment.
He is also the great-grandson of Adrien Lachenal, elected President of the Swiss Confederation in 1896, and the grandson of Marc Peter, Swiss envoy to the United States from 1919 to 1939. The dual American-Swiss heritage is central to his identity and to his perspective on business and philanthropy.
