Our Values

Do the right thing

One of our core operating principles since our first days working with clients, has been to not make technical decisions for non-technical reasons. This simple maxim perfectly encapsulates the weight we place on doing the right thing. Given the nature of recent failures in our industry, it is something the drives behaviours right across our business.

Be an agent for positive change

We strive to create a positive impact through our actions and are constantly looking for ways to improve and make a difference. We believe that every action we take, big or small, has the potential to create positive change. Working together, we can achieve great things and leave a lasting impact on our built environment.

Always look for improvement

Catalyst can only deliver against our other core values if we continue to develop our own skills, knowledge, technology, competence and structures. It will always mean adopting a “growth mindset” and believing that we can improve if we work hard on ourselves, our services and our software. Innovation is at the heart of our business. We innovate not only in our services and software, but also in our business model and organisational model.

Be a great teammate

Being a great teammate means supporting one another when it’s needed and holding each other to account when that’s needed. It means actively listening to feedback and doing our best to make adjustments to our own behaviours (where necessary). It means being approachable and helpful to both internal and external teammates. Where we work with external teams, we exercise empathy and emotional intelligence.
