About Fathom Data

Built on expertise. Driven by people who care.

At Fathom Data, we build things that last. We are a full spectrum data consultancy covering data science, analysis, software development and AI based in South Africa, working with organisations globally, and everything we do comes back to the solutions we deliver, the expertise we bring, the relationships we form, and the trust we earn. This page is about the people and values behind all of it

The team behind the work. The values behind the team.

The IQ + EQ Story

Born from experience, built on belief

Fathom Data was founded by Andrew Collier out of a simple frustration. Organisations had data but weren't getting answers from it. He believed the root cause ran deeper than methodology or tooling. The best technical work comes from people who are engaged, invested and working somewhere that brings out the best in them.

Andrew set out to build something different. A place where rigorous data science and engineering sat alongside real curiosity about the client's world. Where the team cared about outcomes, not just deliverables. And just as importantly, built on a culture that allowed people to thrive.

Over the years that team has grown into a group of people with backgrounds spanning astrophysics, environmental sciences, psychology, health sciences, software engineering, and more - all brought together by a shared approach to solving problems. We call it IQ + EQ: the technical depth to solve difficult problems, and the human understanding to know which solutions will actually deliver.

What we build

The foundation behind everything we do

Trust

Integrity is non-negotiable for us. We communicate openly, hold ourselves accountable, and foster the kind of honest dialogue that allows great work to happen.

Relationships

We take a human-first approach to every engagement. We treat everyone we engage with, with dignity and respect, and we believe that truly listening and understanding is just as important as any technical skill we bring to the table.

Solutions

Solving hard problems is what we love and what we do best. We bring creativity and rigorous technical thinking to every challenge, delivering work that is built to last and designed to have a meaningful impact.

Expertise

We know our craft. Our team is highly qualified, experienced, and trusted by clients navigating complex technical challenges. We also know that expertise is never complete. So we keep growing, keep learning, and keep raising the bar.
