John White’s Biography

John White is Founder and Chief Investment Officer of Calibrate Partners, where he manages the “Calibrate Master Fund”.

Initially a single-family office, Calibrate Partners has grown into a boutique finance house that provides clients with a curated service and exceptional risk management. The firm has three separate but complementary divisions: Wealth Management led by Co-Founder Michela Ferrulli; Hedge Fund; and Tax Advisory.

In addition to his work at Calibrate Partners, John also invests in early-stage company formation and works closely with Deep Science Ventures, where he is a director and capital provider for the group.

John created Calibrate Partners after retiring from his role as Partner and Hedge Fund Manager at GLG Partners, where he founded the award-winning “Alpha Select Hedge Fund” which became a flagship fund and generated exceptional returns for investors even during the financial crisis. During his time at GLG, John won the Euro Hedge Award for the best Long/short Hedge Fund, further recognition of his achievements as a first-class Hedge Fund Manager.

Prior to this, John ran the UK Equity trading division at Morgan Stanley and went on to run the European Equity Proprietary Trading division. As a former UBS Equity Derivatives Trader, John was well equipped to take on the role.

John is a supporter of the British Heart Foundation and Help for Heroes, and undertook a charitable parachute jump for the latter in 2014. He is also passionate about helping children through divorce and has campaigned before the House of Lords to change the law and recognise Parental Alienation as both a legally definable concept and a palpable issue.

In 2017 John completed a TRIUM Executive MBA at the London School of Economics, NYU Stern School of Business, and HEC School of Management.

In his spare time, John is a keen golfer and fly fisherman and a member of Wentworth Golf Club.
