People of Vox: Theo van Zyl
Theo reflects on a lifelong relationship with communications technology, his journey into product leadership and his ambitions for extending connectivity across South Africa.
“The thing was called ‘fire’, and it was brought back to the cave by Og the inventor, who said he found it eating a tree. You had to keep it in a little cage of stones, he said.” ~ From ‘How It All Began…’ by Terry Pratchett
Question: What do Theo van Zyl, Head of Wireless at Vox, and Og the Inventor, also known as ‘the first caveman to cultivate fire’ and brought to us by author Terry Pratchett, both have in common?
Answer: They are both obsessed with the latest technology of the day, and how it can be used to help people and improve their lives.
(Editor’s note: You can read the short story of Og and his lifelong quest to master early technology here. Be warned: you will probably laugh out loud.)
Moving onto a more serious note…
People have been fascinated by the technology of the day for as long as we’ve been human, and for Theo, a life-long and highly practical love of technology began when he was still a child. Today, as Vox’s Head of Wireless, he is focused on building nimble teams and customer-first products, as well as bringing affordable connectivity to South Africa’s citizens, no matter where they are in the country.
We speak to Theo and find out more about how technology is front and centre in his life, both at work and at home, on a daily basis.
Telecomms in His Veins
Theo was still in primary school when his passion for electronics and communication began, and he describes fixing radios and building circuits as a child.
“My interest started with the ‘How and Why’ book range, especially electronics,” he explains. “As a child, I built electronic projects that did actually work, and I was always dismantling electronic equipment to understand the underlying processes. As a teenager, I made pocket money by repairing and building electronic circuit boards.”
That early curiosity matured into technical depth across analogue telephony, telex, data modems and later fibre, LTE and satellite. He also studied e‑commerce at Unisa and was involved in early online billing and payment gateway projects. His breadth of experience shows through in his product approach: he is comfortable with legacy systems and keen on combining them with modern ideas.
A Multi-Disciplinary and Empowering Team Leader
With more than three decades’ experience, including some 15 years heading up another ISP, Theo is a veteran of the telecommunications industry.
He explains: “From running around fixing analogue data copper line services, I have also spent time as a lecturer in data communications, mathematics and electronics. I then moved into practical roles in electronic data interchange, IP network design and product management across multiple disciplines – which is what I love the most, and where I’ve now been for around 25 years.”
He says: “Today, my job focus includes defining product strategies and managing the life cycles of products, leading the Wireless product team members, and ensuring that company strategic and financial goals are met. A key piece of the puzzle in delivering an end-to-end product portfolio includes cross-functional collaboration with areas across the business, including systems, marketing, PR, sales, channels, finance, networks and service delivery.”
Theo aims to keep his team at a manageable size so he can stay engaged with each area without losing control. He leads a compact team, organised around specialist areas, as follows: “Craig oversees Wi‑Fi for both consumer and enterprise; Chris and Kaylee look after LTE, 5G and APN products; Kathleen manages satellite services; Nikita handles microwave wireless; and Kolofelo manages manual feasibilities and operational tickets.”
Daily work for Theo is very collaborative. He coaches and empowers his team, preferring to avoid micromanagement, and values bringing the broader team together to get multiple perspectives on a problem: “Micromanagement kills creativity,” he says. “I prefer to give people the freedom to try, possibly fail, and learn. I actively support piloting and experimentation, provided it doesn’t breach regulatory or company policy!”
Vox and Theo: The Perfect Fit
With Theo’s leadership characterised by empowerment, rapid decision‑making and a tolerance for well‑informed risk, he was understandably drawn to Vox’s culture and strategy, which embraces being nimble and cultivating a low‑red‑tape environment that gets things done quickly.
“Here at Vox, if the boss says do it, then you do it because you know you have the go-ahead!” he notes, contrasting Vox with organisations that can take 18 months to bring a product to market.
“This ability to act rapidly, combined with a collaborative culture where colleagues readily help each other, is what I value most. At Vox, things happen fast. I believe we are better positioned than many competitors because we can move quickly, learn speedily from experiments that don’t work, and then try another approach if need be.”
Theo positions product management as an end‑to‑end responsibility: “As our esteemed CEO, Jacques du Toit, is known to clarify, ‘You need to be the CEO of your own product’, meaning end to end, across every cost, every vendor, every customer interaction.
“This means being hands-on across finances, marketing, vendor relationships, costing, sales enablement and customer experience. Customer experience is also a priority: if internal processes let customers down, product teams must own the problem, resolve a customer’s issues, and implement improvements into future workflows.”
Affordable LEO Connectivity for Wider Access
“Technology is teaching us to be human again… the ability to witness and experience the lives of others anywhere around the world, often in real-time, awakens in us our innate empathy for each other.” ~Simon Mainwaring, businessman and author
Theo has a vision of being part of the rollout of affordable connectivity to rural and underserved communities through Low Earth Orbit (LEO) Satellite services. He describes this as being a major personal and professional ambition: getting low‑cost, operational LEO services into South Africa so that rural citizens can access connectivity comparable to urban Fibre or LTE users.
“I believe Vox is uniquely positioned to pursue this and capable of delivering services, with the success of GEO services bearing testimony to this. I am confident that Vox can achieve our goal of bringing connectivity to all rural citizens over time,” he says.
“I am passionate about the amazing possibilities that LEO satellite services could bring to the people of South Africa, bringing excellent connectivity to anyone across the country, no matter how remote they might be. My ambition is to launch an affordable LEO service so that rural South Africans can access connectivity the same way people in towns do.”
Hobbies and Hacking (You Can’t Make This Stuff Up…)
Away from work, Theo is an enthusiastic electronics hobbyist and home automation enthusiast. In the past, he’s also embraced amateur radio activity: he holds a ZR licence and recalls sending data between computers over radio long before dial‑up became widespread.
He has spent the last decade building smart home systems that incorporate voice‑enabled control for gates, lights, pool pumps, alarms and energy monitoring using remote cloud management, and is proficient at integrating different ecosystems such as Alexa and Google. For Theo, it’s not just a hobby but shows his passion for telecommunications in the workplace now brought into the home environment: “Home automation is not a gimmick for me – it’s about integrating ecosystems to make life easier and more efficient.”
He’s walking the talk, in other words. He’s also been known to carry out at least one ethical hack in his time….
Theo once accessed a public Wi‑Fi system that was not secure when he was eating out at a restaurant in Brooklyn, Pretoria. Realising that their Wi-Fi was vulnerable, and being a regular at the restaurant, he quickly hacked into their system while browsing through the menu: “I printed a warning on the restaurant’s printer and alerted the waiter at my table about the need to separate their guest and internal networks…”
(Editor’s note: So, not your average customer when waiting tables then!)
The astonished waiter alerted the manager on duty and needless to say, the next time Theo went to eat there, the Wi-Fi network was significantly upgraded and stronger – although knowing Theo, he could probably have got in again if he’d really wanted to…
The incident underscores his practical focus on security and the real risks of poorly configured public Wi‑Fi.
It also underscores the fact that Theo really does know what he’s talking about – he combines deep technical knowledge with a pragmatic, people‑centred and fundamentally caring approach to launching and scaling services in a rapidly evolving connectivity landscape.
“I am grateful that my experience in the industry, starting with analogue telephones, telex machines, data modems and growing into today’s technology gave me exposure to areas that I never thought I would ever be involved in,” he says. “At Vox I can leverage on that experience and influence and create products that are customer centric and deliver real value, to help change and improve people’s lives.”
And just like the short story mentioned at the beginning: Isn’t technology and progress amazing?! Here at Vox, we are grateful for people like Theo who help us to keep moving forward. Never change, Theo!
“…several up-and-coming young apemen had got the idea and they invented Civilisation – eventually. The village grew. Some of the open plain was turned into fields. Pretty soon hunters like Hal were beginning to look a bit foolish. That’s how it all began.” ~ From ‘How It All Began…’ by Terry Pratchett
