Company Values Drive - We believe the best team members are passionate about what they do, and that propels them to greater heights in their career. It drives them to be part of the best teams where they are exposed to the best ideas. Ownership - We aim to give ownership interest to as many people in the firm as possible, but in return, we expect everyone to act like owners. "Not my responsibility" is a repugnant phrase to us. Judgement - We look for team members who consistently look at the big picture and spend their time on the activities that most drive PnL. They are pragmatic with their time; they don't stick to their narrow domain if it doesn't move the needle.

Competence - We value people with high intellectual horsepower. They have already become an expert in one or more domains and learn extremely quickly when in unfamiliar territory.
