    Norrsken22’s Lexi Novitske on how China is winning African tech

    Chinese companies have built their position in African technology one layer at a time – first phones and telecoms equipment, then fintech and now the AI models that local start-ups build on. American private capital, meanwhile, is pulling back. Lexi Novitske, general partner at Norrsken22, thinks US investors will regret it. Novitske moved to Nigeria in 2012 and has invested from Lagos ever since. Norrsken22, a pan-African growth fund backed by Nordic tech founders including those behind Klarna, Skype and Minecraft, closed its debut fund at US$205-million in 2023. It is now about halfway through deploying that capital, with no exits yet. In this episode of the TechCentral Show, she expands on the argument TechCentral reported last week: that African start-ups are increasingly building on Chinese AI models such as Alibaba’s Qwen because they are cheaper and more available, and that the US risks losing both a young, digital-first market and access to its data. In the interview, with TechCentral editor Duncan McLeod, Novitske also discusses: • How Nigeria’s start-up scene has changed since she began as an angel investor; • Why unpredictable regulation and a shortage of top talent are bigger obstacles for Nigerian founders than power cuts; • How Chinese-backed OPay and PalmPay won Nigerian fintech by absorbing years of losses, and why that now makes regulators uneasy; • Why Silicon Valley’s AI boom has drawn venture capital away from Africa, and when she expects it to return; • Why Egypt and South Africa offer the best opportunities right now, with Nigeria likely to follow; and • What Optasia’s oversubscribed JSE listing means for Johannesburg, why the biggest African fintechs are looking to New York, London and Hong Kong instead, and why one or two winners can return an entire fund.

    Dominic White and Adam Ely on AI agents going rogue

    AI agents are no longer a thought experiment for security teams. They are breaking out of test environments, hacking real companies and, according to one of our guests, already going rogue inside large businesses. In this episode of the TechCentral Show, TechCentral deputy editor Fanie van Rooyen talks to Dominic White, MD for South Africa at Orange Cyberdefense, and Adam Ely, GM of AI security at Check Point, about the escalating threat AI poses to cybersecurity. They unpack the incident in which OpenAI’s own agents escaped a test environment and broke into Hugging Face’s systems. White argues the initial breach was far from sophisticated and questions whether OpenAI understands its duty of care. Ely explains why the incident shows that even highly skilled, well-resourced teams can’t rule out agents going rogue. They also take on the widely reported story that three Hacktron researchers used Anthropic’s Claude to take over OpenAI employees’ accounts – a story White calls “deliberately misleading”. Also discussed: • A Check Point customer running 50 000 AI agents – and what happens when they drift • Why sandboxing and human oversight are struggling to keep up • Why even security professionals end up switching off their own agents’ safeguards • The case for monitoring agents from the inside, in real time • Whether AI development can – or should – slow down • Who is accountable when an agent breaks the rules • The Manhattan Project comparison both guests reach for • What they expect to see in the next 12 months Whether you run a security team, build with AI or simply want to understand where the technology is heading, this is a frank conversation with two practitioners who see the threat from all sides.

    Octotel’s Trevor van Zyl on the fibre merger question

    Octotel CEO Trevor van Zyl joins the TechCentral Show to talk about where South Africa’s fibre market goes next – including a potential merger with MetroFibre Networx. Van Zyl told TechCentral that Octotel and MetroFibre Networx are assessing a combination that would create the country’s third-largest fibre network operator, with both companies sitting under a common investor in an AIIM-led consortium. In the interview, he sets out Octotel’s position: just under 400 000 homes passed across the Cape Town metropole, the West Coast and the Garden Route; a balance sheet he says lets the company deploy capital when and where it chooses; and a Western Cape footprint he argues overlaps very little with MetroFibre’s. He discusses the next phase of roll-out, too. As networks push into lower-LSM areas, “the commercials and the economics start changing”, he says, and affordability now reaches well into the middle class. He rejects the idea that fixed-wireless access can substitute for fibre in dense settlements – wireless has improved dramatically, he says, “but when you look at the actual demand case and what is required in those environments, it absolutely has to be fibre”. The more important question, in his view, is how to distribute it economically once you get there. On Openserve’s move into the ISP business, Van Zyl is relaxed. He says he understands why Openserve did it, but that Octotel will not follow: “We certainly don’t want to become an ISP. We’re not good at being an ISP.” He also expects consolidation among ISPs as networks saturate, sees low-Earth orbit satellite as complementary to fibre rather than a threat to it, and will not rule Octotel out of any future move by MTN on fibre network assets.

    TCS+ | Specops' Darren James on continuous trust in an AI world

    Specops Software’s Darren James explains why identity checks alone no longer stop determined attackers. Traditional approaches to access security no longer hold up in hybrid, cloud-first environments – and AI is widening the gap. In this episode, host Kevin Smith speaks to Darren James, senior product manager at Specops Software, about the distance between how organisations secure access and how people actually work. Businesses have poured money into identity-based controls – passwords, multi-factor authentication, zero-trust initiatives – yet breaches keep rising, because attackers increasingly exploit trusted identities rather than technical vulnerabilities. An intruder holding legitimate credentials looks like an authorised user and can operate undetected. That points to a shift in security thinking: verifying the user’s identity is no longer enough. Access decisions must also account for the device being used, its security posture and whether trust should hold for the length of a session. Working through a real-world breach, James shows how a single compromised account escalates into a serious incident, and where a more contextual approach to access control could break the attack chain before damage is done. The discussion reframes zero trust as an ongoing process rather than a one-time authentication event, and makes the case for layered verification. He also looks ahead to automated attacks and the rise of non-human identities – service accounts and AI agents among them. As organisations lean harder on autonomous systems, identity-centric models will face pressures they were never designed for. The executive takeaway is this: the cybersecurity battleground is shifting from identity verification to continuous trust. In an era of AI-driven threats and hybrid work, organisations need to stop asking “who is accessing the system?” and start asking, continuously, “should this access still be trusted?” Don’t miss the discussion.

    TCS+ | Why South African workers must become supervisors of digital labour

    ADG’s Cliff de Wit on why the next management challenge is overseeing teams of autonomous software agents. Not long ago, organisations were experimenting with generative AI to draft e-mails, summarise documents and answer questions. Today agentic AI is changing what the technology is for. In a conversation on TechCentral’s TCS+ podcast, Cliff de Wit, MD for South Africa and group chief innovation officer at Accelera Digital Group (ADG), argued that the real story is not machines replacing people but a fundamental shift in how work gets done — and where humans create value. Rather than completing individual tasks on command, AI agents can be given an objective and left to determine how best to achieve it. De Wit illustrated this with a know-your-customer (KYC) use case in which agentic AI is already automating complex workflows and accelerating business outcomes. AI is no longer simply a tool that assists workers. Increasingly, it is a digital workforce in its own right. In a country with one of the world's highest youth unemployment rates, concerns about automation are understandable. But De Wit challenges the idea that AI should be viewed purely as a job-replacement technology. "The human skills involved in business are fundamentally changing, but the basics of business still remain," he said. Businesses will still need people to solve problems, exercise judgment, build relationships and drive innovation. What changes is how those outcomes are achieved: as routine and administrative work is automated, workers move up to activities where uniquely human skills matter most. The sharper risk is distributional. Without investment in education, training and digital skills, AI's productivity gains could widen existing inequalities — not because jobs disappear, but because opportunity concentrates among those who know how to work with the technology. AI literacy may soon matter to employability as much as computer literacy did during the digital revolution. Organisations are already deploying agents into operational environments, in some cases slotting them into workforce structures alongside human employees. Leaders are no longer managing only people; they are managing mixed teams. De Wit believes businesses are better prepared for this than they think. Companies have long used governance frameworks and risk controls to oversee human decision-making, and many of the same principles adapt to digital workers. Whether a decision is executed by a person or a system, accountability, escalation and oversight remain essential. Which decisions should be delegated, then, and which should stay under human control? De Wit's answer comes down to risk, and he sets out a framework for categorising it. The future, on his reading, is unlikely to be fully autonomous. Successful organisations will run human-in-the-loop models in which AI handles execution while people supply direction, judgment and accountability. De Wit is optimistic. Many local organisations are still experimenting, but a growing number are moving past pilots to solve real problems and generate measurable value. For leaders, the question is no longer whether to adopt AI, but how to do so responsibly, effectively and inclusively. The future workforce will consist neither solely of humans nor solely of machines — it will consist of humans who know how to lead, govern and orchestrate digital labour. And that future is arriving faster than many realise. Don’t miss a great discussion!

    Icasa's rules skip the real bottleneck: ACT

    Communications regulator Icasa’s draft rapid deployment regulations – a critical intervention for the sector – risk failing unless the regulator brings municipalities into the process, according to Nomvuyiso Batyi, CEO of the Association of Comms & Technology (ACT). Speaking on the TechCentral Show with TechCentral editor Duncan McLeod, Batyi said Icasa had consulted network operators and fibre companies but not the South African Local Government Association, which represents the municipalities that will have to apply the rules. “You cannot just develop regulations without talking to all the parties,” she warned, arguing that Icasa should follow energy regulator Nersa’s approach to municipal engagement. Asked when final rules might realistically be in place, she said 24 months – provided Icasa works through local government first. On enforcement she was more optimistic. Section 21 of the Electronic Communications Act, amended in 2014, already empowers Icasa to set uniform procedures for permits and approvals at a reasonable fee, she said. “A lot of people may have missed the amendment.” The gap is dispute resolution: the draft assumes disputes between licensees, leaving operators without recourse when a municipality refuses a way leave. At Icasa’s public hearings this month, ACT proposed binding municipal deadlines, deemed approval and damages claims for failing to respond to requests in time from telecoms providers. ACT also objects to the detail in Icasa’s proposed national infrastructure database. Batyi supports mapping in principle but said the granularity sought would expose competitively sensitive information and create construction mafia and cybersecurity risks. Beyond rapid deployment, Batyi listed four priorities on her plate: the newly finalised Rica framework agreement on Sim card verification, licence renewals by 2028, Icasa’s end-user and subscriber charter regulations and the Electronic Communications Amendment Bill – which she described as “embarrassing” in its current form. ACT represents Vodacom, MTN, Telkom, Cell C, Rain and Liquid Intelligent Technologies. – © 2026 NewsCentral Media
