Spencer Greene

Spencer Greene brings a wealth of financial expertise Coupled with 30+ years of commercial software experience. His deep knowledge of trading, exchanges, investment, and commercial banks has directly benefited many of the world’s top financial institutions.

He has worked extensively on-site with global liquidity venues and market makers on optimizing their next-generation enterprise architectures, from latency reduction to increased cyber security.

Mr. Greene currently runs Joompi Capital Management, a family office / hedge fund dedicated to automated trading strategies.
