Summary
I'm an entrepreneur, data scientist, and occasional angel investor. Most of what I've built and supported starts with the premise that good use of data yields better decisions and a better world. Early in my career, I was fortunate to be part of two great early startup teams at PayPal and LinkedIn. I designed and built much of PayPal's machine learning technology to detect fraud, and I led the data team at LinkedIn. I have founded four companies: Team Rankings, Circle of Moms, Bonafide, and Change Research. I continue to work with Team Rankings, and am CEO and Chair of the Board at Change Research. Circle of Moms was acquired in 2012, and Bonafide shut down in 2016. I'm interested in businesses/products that are consumer-facing, have a strong data component, and can have large positive effects on the world. I invest only occasionally. If you're reaching out to me about investing, please include a sentence or two that indicates you read my LinkedIn profile :)
