Lee's outstanding track record is a testament to the thoughtfulness and insight that he brings to every issue. He listens, dissects, and then weigh in, and it's that consideration that makes him such a valuable partner.
Lee is the the best. He's a close friend and someone I look up to professionally. Lee and I built our professional relationship when I helped drive the acquisition of his company - Karma - for Facebook because I was so impressed with his openness, energy, and way of thinking about the world. I was working on a project internally that was competitive and for me to champion acquiring someone was almost like digging my own grave - but Lee was that good - always work with people who are better than you. He's an amazing investor b/c there's no question that is too dumb of beneath his time to help from small issues like what to use your company credit card points on to major strategic shifts. The best.
