Veteran venture capital firm Venrock, an investing arm of the Rockefeller family, has backed several successful tech companies since its inception in 1969: Intel, Apple, DoubleClick, to name a few. A recent win is the sale of Dollar Shave Club to Unilever for $1 billion; it also was one of the backers of Nest Labs, which was bought by Google for $3.2 billion in 2014. Venrock partner David Pakman said his firm looks for digital business models that can disrupt slower-moving incumbents. He noted that traditional firms are losing to tech startups because they don’t know how to talk to the digital customer. In contrast, digital-first firms tend to be ‘conversational’ brands skilled in engaging the always connected customer. Pakman discussed Venrock’s strategy on Wharton Business Radio’s Knowledge@Wharton show, which airs on SiriusXM Channel 111.
