About

I have led go to market in frontier markets for large and small companies, from Google’s initial push into maps in the mid 2000s to Facebook’s early mobile efforts, to pushing the boundaries of social photo editing and drone data, to ultimately launching PayJoy, a Silicon Valley-based fintech, in 20 countries. I led GTM for the Stellar Development Foundation several years, and am currently pushing the boundaries of private AI with Knapsack.
