Jonathan Heller is the chairman, founder and co-CEO of Firsthand, a New York AI startup building Brand Agents - AI representatives that talk directly to consumers on behalf of publishers and brands. An adtech lifer, he co-founded the online video advertising platform FreeWheel in 2007 and sold it to Comcast for roughly $360 million in 2014. At Firsthand he is reuniting with his old DoubleClick colleague Michael Rubenstein to argue that generative AI is not a better ad-serving engine but an entirely new medium for reaching people.
