Let's Talk Data

Privacy, Power, and Accountability| Amenda Makhetha-Sebake on Privacy, Trust, and the Gap Between Law and Reality

Your personal data is sitting inside institutions you trust; banks, telecoms, technology companies, being processed, protected, and in some cases misused, in ways most people never see and rarely question. Amenda has spent her career being the person responsible for what happens to it. A former litigator who found her way into data privacy before most organisations knew they needed it, she has built privacy functions from scratch across telematics, telecommunications, and financial services and today leads data privacy at one of South Africa's most significant financial institutions. In this conversation, she is candid about where most South African organisations really are on POPIA compliance and it is not where they say they are. She talks about the difference between cybersecurity and data protection that even senior professionals confuse, what privacy by design actually looks like inside a data engineering team, and why the growing economy of buying and selling personal data is something the regulator is struggling to contain. She also asks the question that sits underneath all of it: in an age of generative AI, where your information is already out there in ways you cannot reverse, is privacy still something any of us can genuinely control? Or has it become, as she puts it, a facade? This is not a compliance conversation. It is a conversation about power, who holds your information, who benefits from it, and who is actually accountable when something goes wrong.

Data, Land, and Justice | Faith Burn on Building Agriculture That Works for Everyone

What does it mean to build an agricultural system that is not just more efficient; but more just? In this episode of Let's Talk Data, Lebogang Langa sits down with Faith Burn, Chief Technology and Operations Officer at the Land and Agricultural Development Bank of South Africa. Faith has led technology across some of South Africa's most complex organisations - Eskom, Novartis, Tsebo, and now Land Bank. In this conversation, she speaks candidly about the digital divide facing rural farmers, the ethics of agricultural data ownership, and what it would take for South Africa to move from talking about inclusion to actually building it.

No Legacy, No Limits - Gita Daya on Building Bank Zero from the Ground Up

Most banks are still tinkering at the edges. Bank Zero bet everything on building differently. Behind that bet is a technology leader who has spent decades learning not just how to build systems, but how to build the judgment to know which system to build. Gita Daya is CIO of Bank Zero and one of the most experienced technology leaders in South African financial services. In this conversation we cover the architectural philosophy behind one of the continent's boldest banking experiments, the real meaning of innovation in a heavily regulated industry, and what AI is actually exposing about the state of technology leadership across the sector. But the conversation goes further than technology. We talk about power, identity, stewardship and what it means to build something you'll eventually have to hand to someone else. It's a rare combination, technical depth and genuine human honesty from a leader at the top of her field.

The 2026 CDO Mandate: Semantic Models and Reciprocal Africa-US Partnerships | Wendy Turner Williams

In this episode of Let’s Talk Data, Lebogang Langa sits down with Wendy Turner Williams to explore what the 2026 Chief Data & AI Officer mandate truly demands. From enterprise intelligence and semantic modelling to board-level accountability, this conversation examines how the role of the CDO is evolving beyond data management into systems leadership. What does it mean to design architectures that don’t just scale technically, but scale responsibly? How do leaders prove ROI while managing regulatory exposure, model risk, and long-term societal impact? Drawing from her leadership across Microsoft, Salesforce, Tableau, and now as Co-Founder of SymphraAI, Wendy shares how enterprise intelligence is shifting from dashboards to decision systems, where semantic clarity, governance discipline, and predictive value are non-negotiable. The conversation also moves beyond enterprise walls to global equity. We challenge the dominant model of AI education partnerships, often structured as one-way transfers of funding, curriculum, or talent. What would a truly reciprocal data and AI education partnership look like between Africa and the United States, where both sides contribute knowledge, shape standards, and learn from one another? This episode is about leadership in the intelligence era: architecting meaning through semantic models, designing systems that outlast market cycles, and redefining global collaboration.

CIO of the Moment: Wim De Bruyn on Building Resilient Platforms, Talent, and South Africa’s Tech Future

In an era where trust, scale, and speed define financial services, technology leadership can no longer be reactive. In this episode of Let’s Talk Data, Lebogang sits down with Wim, CIO at Capitec, about what it truly means to build reliability , not just into systems, but into organizations and people. The conversation explores how large banks move beyond firefighting toward resilient, product-led platforms; how accountability for reliability shifts from engineering teams to leadership; and why CIOs must play an active role in shaping South Africa’s tech talent pipeline. This is a conversation about building systems that can fail gracefully, teams that can move confidently, and an ecosystem that can compete globally while serving local realities.
