Company Values
  • We are Multistakeholder - As an institution, we exist in a broad stakeholder context, which means that we must organize, incentivize and measure ourselves against meeting the needs of all of our stakeholders — our customers, our shareholders, our employees and families, our local communities and our world.
  • We are Mindful - We seek to be present and aware, to be respectful, active listeners (with each other and with our customers alike), and to pay attention to detail. We don’t rush to judgement, and when we are swept up by strong emotions we patiently observe and acknowledge them and try to not just react. Our mindfulness leads to better understanding, and more respectful, careful and deliberate choices.
  • We are Driven by Excellence - We are driven by our mission and our passion for customer success. Being driven also means that we relentlessly pursue excellence, that we do not tolerate mediocrity, that we reward based on merit, and that we work intensely to achieve our goals. Being driven doesn’t mean that we are assholes and plough over people or tolerate a culture of aggressiveness. We are a team. Part of our drive is to bring everyone along in our collective achievement.
  • We are High Integrity - We seek open and honest communication, and hold ourselves to very high moral and ethical standards. When we say we will do something, we do it. When we are having difficulty and need help, we talk about it. We treat each other and our customers with the utmost respect. We reject manipulation, dishonesty and intolerance. We welcome vulnerability and uncertainty, which needs to be listened to in order to bring people along, and helps us to constantly learn and improve. Our customers and partners implicitly experience us as high integrity, and our customer centric choices demonstrate this to them again and again.
