Hoffman is a son of Amalia Hoffman of Larchmont, New York, and Edward M. Hoffman of Montvale, New Jersey. Amalia Hoffman is an author and illustrator of children’s books. Edward M. Hoffman works in New York as a software engineer and software consultant to the financial industry.
Hoffman founded Kyber Systems in his junior year at UC Berkeley, as a way to pay for school. Kyber was sold to Human Ingenuity in 1997. Hoffman founded Bridgepath Inc. in 1998, which was acquired by Bullhorn Inc. in October 2002. Also in 2002 he sold a website GetRelevant to Lycos. He then became chair of the Stonebrick Group through 2006, which sponsored networking events in the San Francisco area such as one called the Silicon Forum. He reportedly once showed up to a meeting in a rented truck, and parked blocks away to reduce his chances of being seen. Hoffman is called an expert networker, and described by one author as a "catalyst", because he often "maps" people to see how they fit into his social network. Hoffman is a speaker at events in the technology industry, WSJ Blogs call him "a fixture in the Silicon Valley scene," and Gawker Media's Valleywag refers to him as "uberconnected."
Hoffman became CEO of LiveRamp when it spun off from Rapleaf in 2012. On May 14, 2014 Acxiom announced that it had acquired Liveramp, a company spun out of Rapleaf and co-founded by Hoffman for $310 Million. 
Hoffman is a contributor to the Huffington Post, often on political subjects, as well as Business Week and his own blog called Summation. Hoffman is a Republican and a political contributor. Hoffman is a guest editor for blogs.com where he has contributed to the "Top 10 Coolest Blogs on Data,"  as well as other tech publications. Hoffman contributed to Council on Foreign Relations papers in 2004.
Hoffman was reported by Silicon Valley blog VentureBeat in 2007 of editing his own Wikipedia article. Hoffman responded that he removed inappropriate comments. Gawker mentioned a controversy surrounding privacy practices at Rapleaf.
