    AI’s Kiwi gatekeeper inside Microsoft

    When global giants argue about which AI models are safest, smartest and ready for prime time, a New Zealander in Redmond, Washington is one of the people making the call. Steve Sweetman leads the team at Microsoft's global headquarters deciding which AI models make it onto Microsoft Foundry – the platform that now offers more than 10,000 models from OpenAI, Anthropic, Meta, DeepSeek, Microsoft’s own labs and others, to customers around the world.  Sweetman studied architecture at Unitec in Auckland and fell in love with technology as the industry shifted from manual drawing to computer-assisted design. Stints at Wang and Telecom led to Microsoft New Zealand, then on to Redmond, where he’s spent over two decades at the coalface of new tech: HoloLens, early chatbots, and the shift from narrow AI tools to today’s generative AI platforms. Setting the responsible AI rules He helped set up Microsoft’s Office of Responsible AI, turning high‑minded principles into practical policies and tools. That experience now shapes how Foundry works. Before any third‑party model is switched on for customers, Microsoft runs its own evaluations and has, Sweetman reveals, rejected popular models that didn’t meet its safety bar.  Sweetman explains why the real value is no longer “just the model” but the data, governance and agent frameworks wrapped around it. We talk through concrete use cases from Alaska Airlines using generative AI to personalise travel planning, to CVS Health applying models to cancer research, and tiny Australian startup Lyrebird building multilingual tools to close gaps between patients and clinicians. For New Zealand, where AI adoption is lagging and talent is thin on the ground, Sweetman is bullish. You don’t need to build your own foundational model, he argues. You can plug into powerful platforms like Foundry, understand the safety guardrails, and start experimenting. If you want an insider’s view of how Microsoft is curating the world’s AI models – and a Kiwi’s take on what that means for local businesses – this is an episode worth queuing up.

    Australia's new unicorn and its digital twins

    This week on The Business of Tech, I talk to Neara co‑founder Jack Curtis about how a “physics-based digital twin” of electricity grids is changing the way we plan, build and protect electricity infrastructure – from Taranaki to Texas.  Neara has just raised A$90 million in a Series D round led by US investment firm Technology Crossover Ventures (TCV), which also invested in Netflix, Spotify, Facebook and Xero. That takes total funding in Neara to about A$180 million, as some of the world’s most exposed utilities rush to digitise their networks in the face of extreme weather and the clean‑energy transition. Neara’s origin story isn’t very corporate. Software engineer and Neara co-founder, Daniel Danilatos, hacked together a better power line design tool over a weekend for his wife, a line designer frustrated with clunky legacy software. The prototype spread “organically” in an industry notorious for moving slowly. Within a few years, it had become the basis for a company now modelling around 90% of Australia’s electricity networks and working with most major utilities in Texas and California, and with a roster of New Zealand clients. Predicting when things break Most “digital twins” in utilities have been glorified 3D maps – pretty visualisations that don’t give asset owners enough confidence to make high‑stakes decisions. Neara instead builds behavioural models where every pole, line and substation is infused with real‑world physics: how it bends in a storm, heats up as load rises, or fails when gusts hit a certain speed.  As Jack puts it, if you look at the pole outside your house in a gale, it should behave exactly the same way in Neara’s model – right up to the moment it snaps. We also look at how physics‑based models help solve “good problems” like renewables congestion. Neara simulates how much extra power can safely be pushed through existing lines, where new wind or solar should connect, and how different mixes of generation and load will behave over 10–30 years.  That’s crucial for countries like New Zealand, which sprinted to 80–90% renewable electricity without fully modelling system‑wide side‑effects such as dry‑year risk and fossil‑fuel fallback. I found this chat fascinating and I’m sure you will too if you are interested in how evidence-based digital twins can transform industries.  Streaming on Apple, Spotify, iHeartRadio or wherever you get your podcasts.

    Inside the levitation lab: OpenStar’s quest for energy’s Holy Grail

    A half-tonne metal “donut” silently floating in a vacuum chamber in Wellington might sound like science fiction. But as you’ll hear in the latest episode of The Business of Tech, it’s very real – and it could reshape New Zealand’s role in the global race for nuclear fusion. This week, I sit down with BusinessDesk journalist Greg Hurrell to unpack OpenStar’s dramatic new milestone: levitating a superconducting dipole in a near-perfect vacuum and firing superheated plasma around it.  It’s a key proof point for the Wellington startup’s radically different approach to fusion, one that flips the dominant tokamak design inside out. Instead of surrounding the plasma with giant magnets, OpenStar suspends a powerful magnet in the centre of the chamber and uses Earth-like magnetic fields to confine the plasma. ​Big ambitions, big interest Greg and I were in the room at Open Star last week as Prime Minister Christopher Luxon, Regional Development Minister Shane Jones, Infrastructure minister Chris Bishop, investors, scientists and even a representative from the United Arab Emirates watched the demonstration.  For a company that has only raised a modest $10 million Series A round, hitting this milestone matters. it shows OpenStar can deliver on ambitious engineering promises, exactly what global venture capital wants to see. The government has granted OpenStar a $35 million loan via the Rural Infrastructure Fund to build a bigger prototype – Tahi. Shane Jones, Chris Bishop, and Christopher Luxon listen to OpenStar CEO and co-founder Ratu Mataira explain the plasma firing experiment. Inside-out design We dig into why this “inside-out” design could be simpler to build and maintain than giant international projects, how New Zealand-grown intellectual property in high‑temperature superconductors and flux pumps gives OpenStar a potential edge, and what comes next with its larger Tahi and Maui machines aimed at real fusion and, eventually, commercial-scale power.  We also tackle the hard questions: tritium supply, neutron damage to reactor components, and whether a relatively small team in Wellington can compete with well-funded overseas rivals and decades of tokamak momentum. If you are interested in energy, climate, deeptech or New Zealand’s science system, this episode goes deep on a genuine moonshot as it crosses from lab experiment into serious industrial ambition.  Streaming on Spotify, Apple, iHeartRadio, or wherever you get your podcasts.

    The OpenClaw moment and what it means for AI

    OpenClaw is the moment AI stops feeling like a clever chatbot and starts behaving like something closer to a digital co-worker. In the latest episode of The Business of Tech, you’ll hear exactly why. Veteran software developer and AI entrepreneurMike Hall joins me to break down what OpenClaw actually is in plain language. It’s not another prompt-and-response assistant, but a particularly smart type of AI agent that can wake itself up on a schedule, scan your data and tools, and decide for itself whether there’s work to be done. If it needs to write code to perform a task for you, it will do that too. Mike explains how that simple “heartbeat” loop, asking “Should I do something?” every minute, is the key shift that turns AI from reactive to proactive, and why that’s such a big deal compared with the chatbots most people have used so far. Skills and the hive mind We dig into how OpenClaw goes far beyond the current crop of AI agents baked into office suites and CRM platforms. OpenClaw is designed to live on your own infrastructure, plug into email, files and SaaS tools, and then act autonomously rather than waiting to be told what to do.  OpenClaw has sparked a surge of interest from developers, an explosion of “skills” that any OpenClaw instance can download. The hive mind model central to OpenClaw is unlike anything we’ve seen in commercial agent products. That’s probably why OpenAI has snapped up OpenClaw founder Peter Steinberger and will put him to work developing the next generation of AI agents for the creator of ChatGPT. Sandboxes essential We also cover the risks OpenClaw raises. Running OpenClaw on your personal machine can expose your entire digital life, which is why sandboxes and strict permissioning are essential. What happens when you let agents install community-built skills that might contain malware?  Then there’s Moltbook, the social platform where OpenClaw-powered agents post and argue with each other, and what that experiment tells us about a near future flooded with AI personas. If you’ve heard the noise about OpenClaw and “agentic AI” but still aren’t clear on what’s genuinely new here – and why it matters for your business, your data and your job – this conversation will get you there.  Streaming on iHeartRadio or your favourite podcast platform.

    New Zealand’s energy crunch: Can innovation keep the lights on?

    New Zealand loves to boast about its clean, green energy story. With around 80 to 90% of grid electricity coming from renewable sources like hydro, wind and geothermal, we look like one of the world’s quiet success cases on decarbonisation. But beneath that headline number lies a much more precarious reality. When lake levels fall and gas supplies tighten, our energy system starts to look very exposed.​ In the latest episode of The Business of Tech, I sit down with Melissa Reynolds‑Clarke and Daniel Gnoth from Ara Ake, the national centre for energy innovation, to explore how we can lean on innovation to navigate this emerging energy crunch. The conversation ranges from process heat in dairy factories and meat plants that still run on coal and gas, to the growing risk that international customers will turn away from products that are not backed by genuinely low‑emissions energy.​ Ara Ake sits in the “valley of death” for new technology – that tough space between promising lab results and commercial deployment. Daniel explains how the organisation supports everything from fusion “moonshots” and hydrogen‑electric aircraft trials, to more grounded projects like battery storage at Wellington’s CentrePort, rural microgrids, and ultra‑cheap hot water control that effectively turns our cylinders into a giant, flexible battery. Melissa, drawing on decades in the rural sector and on energy company boards, highlights the brutal realities facing farmers and manufacturers who need affordable, reliable energy today, even as they’re pushed to decarbonise for tomorrow’s markets.​ We dig into some of the most promising levers for fast impact – smarter use of flexibility on the grid, re‑using old oil and gas wells in Taranaki for deep geothermal heat, and new business models that make technologies like biodigesters and community batteries actually stack up in a country of small, dispersed farms and towns. We also talk frankly about the capital gap that still exists between startup and scale‑up, and why system‑wide thinking across regulation, networks, and markets, matters just as much as shiny new tech.​ If you want to understand what New Zealand’s energy transition really looks like on the ground, and where innovation can genuinely move the dial, this episode is for you.

    MethaneSAT: Unpacking New Zealand’s $30 Million space gamble

    In the latest episode of The Business of Tech, we look at the rise and fall of MethaneSAT, the $30 million national space project that was supposed to cement New Zealand as a serious spacefaring nation.  Instead, it became a case study in governance failure, misaligned incentives and lost opportunity.  Launched in March 2024 and lost in June 2025 after persistent spacecraft glitches, MethaneSAT’s methane-sniffing science payload worked but the rest of the system carrying it in space failed. Working in space is risky, and satellites do fail. But as this week’s guest on The Business of Tech, University of Auckland physics professor Richard Easther points out, New Zealand’s involvement in the international MethaneSAT project raised questions from the start.  “What happened… is that we found this opportunity and then we found reasons to do the opportunity,” he told me.  “If someone had come to us in 2018 and said, here’s $30 million, I want you to develop things that will lead to startups, things that will provide the workforce… we could have come up with a plan and it would have been much, much better than MethaneSAT.” Picking winners: "A terrible job" Easther is careful not to scapegoat individual scientists or engineers. His critique is aimed squarely at how New Zealand chooses its science priorities and partners.  “We do a terrible job of choosing science priorities in New Zealand,” Easther said.  “And the people who pushed MethaneSAT were not scientists and do not have visible track records of testing proposals for excellence and competence.”  From governance issues to the gap between what officials were told privately and what the public heard, Easther argues MethaneSAT exposed deep problems in how we govern high‑risk, high‑cost science. But this isn’t just a post‑mortem of a failed satellite. Easther draws a direct line from MethaneSAT to today’s multi‑million‑dollar bets on AI and quantum, warning that without transparent, contestable processes – of the kind used in US “decadal reviews” – New Zealand risks repeating the same mistakes at even larger scale.  The Government yesterday announced another significant science investment, committing $35 million from the Regional Infrastructure Fund to help start-up OpenStar Technologies develop a new, specialised facility for its new fusion machine. Easther says major science investments shouldn’t come at the cost of long‑term, curiosity‑driven funding, pointing to world‑leading local strengths in high‑temperature superconductors and quantum devices that were quietly underwritten by the Marsden Fund decades ago. Tune in to The Business of Tech to hear Professor Richard Easther on what MethaneSAT got wrong, and what we should learn from it. Streaming on iHeartRadio or wherever you get your podcasts.

    Robots and the new physical AI gold rush

    Two Kiwi engineers who helped build the future of self‑driving cars in Silicon Valley are now quietly laying the foundations for the next great tech wave: physical AI.  In the latest episode of The Business of Tech, I talk to Harry Mellsop, co‑founder of simulation startup Antioch, and Adrian Macneil, co‑founder and CEO of data platform Foxglove, for a fast‑paced tour of where robotics is really at as Elon Musk talks up his Optimus humanoid robots. Both founders cut their teeth at the pointy end of autonomy. Harry worked on Tesla’s Autopilot, watching first‑hand how much time and money is burned putting robots into the real world safely. Adrian led key parts of Cruise’s self‑driving infrastructure and developer tooling, helping build the internal platforms that let engineers understand what a robot “saw”, “thought” and did on the streets of San Francisco. Big dollars for physical AI startups  That experience has now crystallised into two companies sitting at the infrastructure layer of physical AI – and investors are paying attention. Foxglove has raised US$40 million US in Series B funding, led by Bessemer Venture Partners with Icehouse Ventures on the cap table, to build the data and observability backbone for robotics teams. Antioch has secured US$4.2 million US dollars in pre‑seed funding, with Icehouse Ventures again involved, to bring Tesla‑grade cloud simulation to any robotics startup that wants to test thousands of edge cases virtually before a robot ever leaves the lab. Integration testing for atoms We explore how these platforms turn messy real‑world sensor feeds into structured insights, shorten development cycles from weeks to hours, and dramatically reduce the risks of unleashing autonomous machines into warehouses, construction sites and farms. Harry explains why “integration testing for atoms” is the missing link in robotics, and how simulation can slash the cost of safety validation. Adrian unpacks the idea of a data flywheel for robots – logging everything, surfacing the rare but dangerous failures, and feeding that back into better models and better code.

    Frontier or followers? How NZ can catch up on AI

    New Zealand likes to see itself as an agile, innovative tech nation. But when it comes to artificial intelligence, the story is more sobering than triumphant.  A new survey of 4,000 business leaders from around the world by research group IDC has revealed that just 8% of companies in Australia and New Zealand can be classified as “frontier firms” when it comes to their uptake of AI. That compares to the global average of 22%. Around half of our firms are classed as “laggards” and risk falling behind. Are we shrewdly waiting on the sidelines for AI to really prove its worth. Or are we merely dabbling with the tech, ill-equipped to embed it in our businesses? AI can be more than “fancy Google” In the first episode of season 4 of the The Business of Tech, I sit down with Sarah Carney Microsoft’s national chief technology officer, to explore an uncomfortable question: are Kiwi companies quietly locking in a decade of underperformance by moving too slowly on artificial intelligence? Carney has a front‑row seat to how “frontier firms” around the world are using AI to rewire their businesses, not just write better emails. In this episode, Carney, a ten-year veteran of Microsoft, spells out why that matters for jobs, growth and competitiveness. She also challenges some of the myths holding local leaders back. Is AI really a threat to entry‑level roles, or could it create better ones? Is governance a brake on innovation, or actually the catalyst that lets people take bolder bets? And why is our national cynicism becoming a liability in a world where experimentation is the new survival skill? If you’re a founder, executive, policymaker or just trying to work out what AI really means for your job and your business in 2026, this is an episode you do not want to miss.
