Early Internet entrepreneur with a focus on online advertising, martech, and fintech. Over the past 15+ years, I've founded, acquired, sold, or remain a controlling shareholder in over a dozen tech companies. Outside of online advertising, I actively invest in contemporary art and serve on boards of different organizations, including the Brooklyn Rail (current), International Foundation for Art Research (current), and the Lynn Foundation (past). I spend time between New York City and Aspen.
