Operator, founder and healthcare executive in NYC. Former institutional investor, continuing a lifelong obsession with observational investing.

I created multiple portfolios on dub as a private investor. They have a range of risk profiles, time horizons, and deliberate position sizing of companies and ETFs.

At this time, my core thesis centers around the normalization of robotics, artificial intelligence, advanced embedded intelligence, and space/ocean exploration, balanced with companies focused on global security, reindustrialization, and defense sector companies whose technology is needed to get us there.

I do not manage outside capital. I am not a financial advisor. These are personal investment strategies, not investment advice.
