i create companies, have two boys and an amazing wife

I start, build, and invest in Internet companies.

As Co-Founder and Chairman of Attentiontrust.org, I am a strong advocate for the rights of individuals to their own data. Currently, I am creating services for turning passive data into active expression through a group called AttentionLab.

I was the founder of one of the first Internet advertising agencies, SiteSpecific, in 1995, and was entrepreneur-in-residence at Flatiron Partners. In 2002, I co-founded Majestic Research on the premise that rigorous analysis of online behavior would lead to better investment research. Majestic has emerged as an important new research firm on Wall Street, counting among its clients leading hedge funds and mutual funds. In 2005, I founded Root Markets, with legendary financial architect Lewis Ranieri as Chairman and lead investor, and CBOT/CME, New York Times and Deutsche Bank as strategic partners; Root has created the first financial services-style marketplace for Internet leads. I am an active angel and advisor to social media startups including Aggregate Knowledge, Downfly and lijit networks. I was an original investor and advisor to del.icio.us.
