For Mr. Schulze, the scion of a family that made billions in mining, a thaw in America’s relationship with North Korea would be potentially lucrative. His firm, SGI Frontier Capital, adopts a high-risk strategy of investing in so-called frontier markets — Ethiopia, Mongolia and elsewhere. He did a number of small deals in North Korea before the Obama administration imposed new economic sanctions in 2016. Mr. Schulze first met Trump family members several years ago when they were exploring business deals in Asia. As CEO of SGI, Gabriel is involved in key decisions of the company that has offices in Singapore, Beijing, Sao Paulo, Tbilisi and Ulaanbaatar. A tall and charismatic figure, Gabriel received his Bachelor’s Degree in Business, with concentration in global trade and commerce. His great-great-grandfather William Boyce Thomson founded Newmont Mining in 1916, listed it in 1925; by 1930 it was the world’s third-biggest mining company and delivered the Schulze family the fortune it invests today. Intervening generations died young, experimenting with their relationship to huge inherited wealth. Mr Schulze’s parents met and married in a New Age commune dedicated to enriching the soul rather than the wallet. The Wake Forest University student nurtured a desire to break away from “boring, plain vanilla” investment activities, pursue a trenchant work ethic, make a difference and do something productive with his “20-mile head-start”.
