We made the classic mistake that all investors make. We focused too much on what they were doing at the time and not enough on what they could do, would do, and did do. I am proud that our portfolio is full of companies where we saw the vision before other investors did and backed a great team. But we don't always get it right. We missed Airbnb even though we loved the team. Big mistake.
