Valtech Values : Share - Dare - Care
  • Share : We pay it forward. We share knowledge with our peers, our clients and colleagues all over the world. We share to connect, to learn, to grow, to be open and to be transparent. We share the passion for making a difference in the world. For making an impact. We share the value of being part of a collaborative, role-based and diverse organisation respectfully embracing different personalities, cultures and opinions.
  • Dare : We thrive in environments that are full of complexity and ambiguity. We dare to challenge not only ourselves and each other, but also our clients to go into unknown territories. Fueled by our shared passion, we dare to trust each other and go new, innovative ways to make extraordinary things happen. We dare to take the lead. To take responsibility even when things have failed. We dare to speak up and to be honest.
  • Care : We care about the end user experience. We care for our clients' businesses and about the quality of the things we create. We care deeply about the vibe and well being of our teams. We care for ourselves and our colleagues to live healthy lives. We care about the world we live in and in taking responsibility for our role in improving human lives and making the world a better place for everyone.
