He sourced, invested in, and executed a partial exit from Vanguart, an ultra-luxury Swiss watchmaker whose timepieces now command up to $200,000 and grace the wrists of collectors like John Mayer, Ed Sheeran, and Michael Jordan—demonstrating his ability to identify rare opportunities and create value across even the most rarefied markets.
