Jacob Rubin is the Founder and Managing Member of Philosophy Capital Management LLC. Philosophy invests long and short across the capital structure with a value-oriented approach targeting securities with asymmetric investment returns.
After graduating with a BA in Economics-Philosophy from Columbia University (2006), Jacob began his career with three years of banking (JPMorgan, Macquarie) followed by an MBA at Stanford (GSB 2011). During those years, he raced bikes and accumulated a unique collection of jerseys as a reward for his efforts (the GFC-era Merrill Lynch-sponsored amateur kit is a gem). He briefly returned to finance at Goldman Sachs only to veer off course to further scratch the academic itch. He earned an M.Phil in Economics at Cambridge University (2013) while rowing Bumps for his college in the M1 boat.
Upon his return to the States, Jacob found his calling at Lonestar Capital, where he spent six years getting at-bats, cultivating a network, and developing pattern recognition. Jacob hung the Philosophy shingle just as Covid hit and spent the past few years weathering endless “tail” events while growing the team and capital base. He traded bikes and boats for trail running shoes and lives with his wife and three children in the Bay Area. When not behind screens, Jacob can be found running ultramarathons on trails or guest teaching at Stanford on subjects like game theory, event-driven investing, and negotiations.
