Our values

We're not your traditional consulting firm. We'll challenge your thinking and assumptions. There may be times when that's uncomfortable, but it will be a journey we will take together.

We won't do all the work for you either; but we will build your capability and we will empower you; so you can do the best work of your life!

As Louise Penny says - "Life is change. If you aren't growing and evolving, you're standing still and the rest of the world is surging ahead."

The Proxima Way

The Proxima Way is the cornerstone of our organisation. It is our manual and suite of policies.


Be Kind, Be Bold, and Be Curious are the values that underpin who we are and how we work. They are behaviours that every team member is expected to practice and against which we consistently evaluate our actions.

Each year we produce a concise overview of our performance and impact. You can read our latest Impact and Sustainability Report here and our GRI Index here.

Our theory of change

Our services

Our theory of change, or impact hypothesis, is simple.  By sharing our knowledge and experience; and by building the capability of others, we can create more impact through the decisions that organisations make.

This reflects our core strategy: to deliver capability-building advice and support programmes that empower senior decison-makers to create actionable plans for driving systemic change.
