About

I believe the best work happens where analytical rigour meets genuine care for people.

My faith is the driving force in my life. Everything I do is to serve God and love others. That conviction has shaped every career move, every venture, and every early morning training run.

I am shaped by the idea of redemptive entrepreneurship: the conviction that business can be a force for creative restoration. Inspired by the thinking of Praxis, I believe ventures should go beyond ethical compliance to actively redeem what is broken. Broken systems, broken access, broken data. That is the lens through which I build.

From almost the first day I used AI, I have been certain of where this goes. I am just as certain that it should make people better, not make them unnecessary. Used well, AI makes us better at the work we already do, and it can even help us become better humans. The tools are already here. What is missing is the skill to use them well, and that shortage is enormous. Helping people close it, then watching what it does for them, is what gets me ticking.

This technology is going to change the world. My purpose is to make sure AI contributes to human flourishing, and not the opposite.

Why I do this

That is why most of my time now goes into Fluent. We want to be your business's AI private banker: we get to know your business, start by understanding where your people are, train them on the tools you already pay for, advise you on what comes next, and refer you to the best when someone else is better placed. We start with training and enablement because AI should augment people, not replace them. In our first few months we have trained 27 companies and counting, and helped each of them work out how to put AI to work in their business. Fluent is still young, and I am deeply grateful for what the Lord is doing there.

Every week I also write Tomorrow Today, our AI newsletter, and Fluent grew out of it. After one of our webinars, three businesses asked us to train their teams, and we have not stopped since.

PeopleRadar and the wider Radar group carry on alongside Fluent, built on a simpler conviction: AI without data is just a fancy demo. I left the comfortable corporate actuarial life at PwC because I saw fragmented workforce data causing real harm. Payroll leakage, invisible absenteeism patterns, decisions made in the dark. We redeem those broken data systems by giving organisations clear, actionable intelligence. In the NPO sector, we help organisations measure and understand their impact, consolidating scattered reporting into something that tells the real story of the difference they are making.

I am South African to my core. I love this country: its mountains, its people, its complexity, and its potential. I want to build things here that matter.

By the numbers.

Building Fluent

Most of my week goes here. We want to be your business's AI private banker: an AI audit to see where your people are, training on the tools you already pay for, advice on what comes next, and a referral to the best when someone else is better placed. 27 companies trained and counting in our first few months, across agriculture, financial services, retail, logistics, mining and more.

PeopleRadar

Building PeopleRadar

AI is only as good as the data underneath it. PeopleRadar is the workforce analytics platform that fixes that for agricultural businesses and NPOs: surfacing absenteeism patterns, overtime abuse and operational insight, and helping NPOs measure the impact they are actually having.

Tomorrow Today

Writing Tomorrow Today

A weekly AI newsletter I co-write with Anton Prinsloo. Accessible, practical, honest, and published every week since June 2025. It distils what actually happened in AI this week into something you can use on Monday morning.

Ventures & projects

Speaking and panels

I talk about AI in plain language, usually with a live demo rather than predictions: keynotes, panels and workshops. If you are putting together an event or a panel on AI, I would love to be part of it.

Invite me to speak

What I talk about

  • AI at work, without the hype

    What changes when a whole team uses AI well, and what it takes to get there. Drawn from training 27+ companies with Fluent.

  • Building live, on stage

    A working app or dashboard built in the room from a plain-language brief, so people see what is possible instead of hearing about it.

  • AI in agriculture

    Making farm and workforce data useful, from PeopleRadar's work with South African agri businesses.

  • Faith, work and AI

    A redemptive view of what this technology is for, and how Christians can engage with it well.

Beyond the numbers

Worship

Faith

I am a sinner saved by grace. Nothing I have achieved can be attributed to my own brilliance. It is all God. I believe deeply in the power of the local church, and I prioritise serving wherever I can. From outreach missions in Lesotho and the Transkei to LIV Village in Durban, my faith is not something I hold. It holds me.

Friends

Community

Above everything, I value people, family and relationships. The best ideas, the hardest races and the most meaningful work: none of it matters without the people you share it with.

Mountains

Adventure

I love nature and adventure. There is nothing like exploring God's creation on foot or on a bike. I am an avid runner, trail runner and triathlete. Life is either a great big adventure or nothing at all.

Simplicity

I aspire to live a simple life and find joy in the small things. A good bottle of red wine at the fire with friends. A sunrise and sunset swim. Escaping the city to find God in the quiet.
