Relationship Science founder Neal Goldman has built what he likes to call "the Death Star of business development."Maybe you know Neal Goldman. Or maybe you know someone who does. A minor celebrity in both Davos and Big Data circles, Goldman sold his first company for $225 million, back when less than a billion dollars was actually worth something. Tonight, I am meeting him for the first time, sharing a train ride to Philadelphia, where I'll get to hear him pitch his latest company, Relationship Science.While waiting in the maelstrom of NYC's Penn Station, I run through what I've learned about him: where he went to school, where his sister-in-law works, and how much cash he donated to Rudy Giuliani's presidential campaign ($6,900).
