Alex Marinier
Silicon Valley, U.S.



Alex is excited to be partnering with visionary entrepreneurs building transformative products. At DCM Alex focuses on a wide variety of sectors, but is particularly interested in the blockchain/cryptocurrency, real estate/travel tech, and digital media spaces. Having underwritten venture capital and growth equity investments in the past, Alex puts his knowledge and analytical skillset to work searching for talented teams building tomorrow’s leading technology enterprises.

Prior to joining DCM, Alex worked at The Blackstone Group in New York City as a private equity analyst where he focused on underwriting secondary purchases of Venture Capital, LBO and Growth Equity funds and portfolio companies. Prior to that, Alex spent time at Angelo, Gordon & Co. working on real estate acquisitions. After graduating from Cornell, he briefly spent time developing a mobile application in the sporting events space, but decided to put it on hold to pursue his career in private investing.

Born in New York to a French expat father and an American mother, Alex is a dual U.S. / French citizen and has cheered on the French national soccer team since before the glory of their sole 1998 World Cup championship. Growing up around his family’s restaurant business in NYC, Alex naturally loves to eat and has been exploring the culinary offerings of the Bay Area. When he’s not working or eating, Alex can be found outdoors wielding a tennis racquet, golf club, or since he’s moved to California, a surfboard.
