Principal & Head of Operations
Stephen joined SignalFire in 2015, where he focuses on investing in and improving human systems — whether that’s marketplaces, AI SaaS, or venture capital.
Before SignalFire, Stephen was an engineer and manager in financial technology: he spent four years managing operations at the ASSU, a nonprofit banking organization at Stanford University, where he was one of the first employees at StartX and co-founded the Cardinal Fund, the country’s largest student endowment management program.
He’s also worked as an engineer at Intel, designing low-power, always-on sensor suites, and at Standard Treasury, a Y-Combinator backed banking technology startup later acquired by SVB. He began his career at Access Genetics, where he implemented AI and CV systems to automate genetic testing and prevent hospital epidemics. Stephen holds a B.S. and M.S. in CS/AI from Stanford, where he researched sentiment analysis, big data cybersecurity, and received multiple leadership awards.
He currently serves on the Federal Reserve Task Force on Faster Payments, the Federal Reserve Task Force on Secure Payments, and on the Finance and Audit Committee of the nonprofit Stanford Student Enterprises. According to his activity tracker, he spends most of his time outside work on a lake, tinkering with electronics, and playing grand strategy videogames.
