The company

Life at Jobbatical

These are the values that guide us:
Start with why. We don’t do things for the sake of having something to do. Keeping the “why” of our actions in mind helps us stay focused on the things that matter.
Don’t wait to be asked. (Make it happen.) We’re not here to sit around and wait for orders. We have ideas and bring them to life.
Go beyond yourself. Comfort zones are great. We love waving at them as we leave them behind.
Choose difficult truths over comforting lies. Saying yes to everything is easy. But many of the most fruitful and necessary conversations are uncomfortable.
Be bold, stay humble. We’re not afraid to take risks and make mistakes to build what we believe in. And we know the world doesn’t owe us anything.
