By uncovering the ground truth, we identify meaningful opportunities and create products that make a difference.

Our focus is on shifting the needle on the metrics that matter.

Hi Mum! Said Dad was born out of an ambition to use creativity, technical know-how and fundamental truths to break new ground and use digital to solve problems for people and businesses.

These are the principles that have been guiding our mission ever since. It’s a simple equation that has seen us drive value for some of the world’s best businesses, organisations and entrepreneurs.

We are family

The idea of family is important to us because we all share a common desire; we want to do our best work and we want to have fun doing it. We can only do our best work when we pull together, as a family.

Being a family means we take an interest in people and their lives. We offer a hand when the going gets tough. We celebrate each other’s personal and professional successes – big and small.

We share knowledge because enriching others is a worthy pursuit. We welcome new colleagues and partners into the family with open arms and we let them know what it means to be part of our family.

We value this so much that we decided to pay homage to it in our name.

We are incisive

We make it our mission to deeply understand our clients’ businesses, the market, and what our users will and won’t do.

With this knowledge, we produce smart, meaningful solutions that have measurable results for our clients. We are rigorous in our approach and show clarity in our thinking.

We are incisive because we understand the bigger picture. We understand the business and customer value our products should create. Our decisions are informed by this understanding.

We are craftsmen

Everyone at Hi Mum! Said Dad is a master craftsman. We turn ideas into the tangible.

This mindset means we always question whether our work answers the challenge at hand. It means we constantly look for improvement. We hone our skills because we don’t stand still. It means we make quality our leading light. It means we exceed all expectations.

The work we put out into the world reflects us as craftsmen—our skill, our attitude, our ambition. It is only right that we do ourselves justice. The work we do here is our best.
