I have been angel investing for the past 15 years in 250 companies. Prior to investing, I founded Del.icio.us and invented tagging before being acquired by Yahoo. I also spent a decade as a quant on Wall Street, and previously got a degree in Electrical and Computer Engineering. I am a historic and club racer, and runs an an annual autonomous vehicle event where teams are invited to try to get their autonomous vehicles around a racetrack.

I invest in most industries with significant success in the past in the API, Fintech, Marketplace, and Dev tools areas.
