Halle Tecco + Jeff Hammerbacher

We're active angel investors supporting founders working on meaningful problems. We invest in data science, digital health, and companies that make science go faster. We get especially excited by companies bettering the lives of everyday Americans.

We are Midwest-born and raised (Jeff from Michigan/Indiana and Halle from Ohio), where we both started our working lives bagging groceries. We met in early 2007 in San Francisco, where we lived for nine years. We married in Italy in 2012 and recently moved to the East Coast.
