If something needs doing, we do it. We take initiative, we take risks, and we empower each other to take on complex challenges. We don’t let fear of failure stop us - the worst thing is not to try.

Integrity

Acting with honesty and transparency. Taking responsibility for our decisions and our mistakes. Never forgetting our commitment to the planet, each other and 44.01.

Collaboration

We can only achieve our mission by working together with trust, openness, and respect. We assume positive intent and are respectful and understanding, even in disagreement or times of difficulty.
