Mark Green has spent almost 30 years in change management — the discipline of helping people in the workplace through big transformation, usually the kind driven by technology and system integration, and increasingly by AI. He'd fallen thoroughly out of love with it: the monotony, the round tables and PowerPoints, the talk of Kotter and change curves, the traditional consultancies selling in ways he disagreed with. His answer was Change Rebellion, launched in April 2023 and built deliberately to be different — no salespeople, no chasing RFPs, just PR, marketing and, in his words, "me being a madman on LinkedIn." Personal branding before everyone was doing it; an approach designed to make people laugh, think and actually remember the message.

The heart of this conversation is what changed him. At Christmas 2020, in the middle of lockdown, Mark and his family caught the Delta variant of COVID. They recovered; he "took the more scenic route" — two months in an induced coma, then another two months relearning how to walk, talk, eat and drink. He talks, with striking candour and warmth, about emerging as "Mark 2.0" (his wife prefers this version, and so does he), about the financial cliff-edge of being a contractor with no income and two tiny boys at home, and about how his new perspective made him incompatible with the old way of working. The rejection he met when he brought "off the wall" ideas to traditional consultancies became the fuel for going out on his own.

There's plenty of lighter texture too: a very funny aside about AI's habit of always telling you you're right (and the claim that some models turn miserable after about seven prompts), Mark's ambition to land a TEDx talk, and a genuinely useful thread running underneath it all — that you never get technology change without human change, and nothing works unless the people are bought into it.

Becky Weatherley is the founder of Talk to Breezy, a non-addictive AI mental health tool designed, as she puts it, to get you off your phone and living your life. You can talk to Breezy, an AI shaped with input from mental health professionals, or record your in-person therapy sessions. Either way you get a summary and a set of 'active intentions': specific, personal tasks for the week that Breezy follows up on, learning what helps and spotting patterns over time.

Natalie asks the questions many listeners will have. Why not just use ChatGPT? Becky explains how general chatbots can pull you into hours of analysis, while Breezy is structured to nudge you into action. Is it safe to share something so personal? Conversations aren't linked to your account details, therapy recordings are deleted as soon as they've been transcribed, and people in crisis are directed to the right helplines. She also explains why she'd count it as a success if you no longer need the app in a year's time.

Becky shares her own story too: a degree in music industry management, running a heavy metal festival at 21, burnout, ten years in digital marketing, and panic attacks from her mid-twenties that led to a stress-related tremor. Her message is that you don't need to have it all figured out to build something, and there's no single quick fix for mental health, just finding what works for you and sticking with it. Talk to Breezy is running a trial with the University of Southampton and welcomes feedback from users.

Tyler Clark works in reinforcement learning — the branch of AI where, instead of being shown examples of the right answer, an AI learns by trial and error. Give it a robot arm and something to pick up, tell it only whether each attempt was good or bad ("a carrot on a stick"), and let it try over and over until it works. Tyler explains the idea beautifully: a reward of +1 for the right thing, -1 for the wrong thing, and an AI whose entire goal is to push that number as high as possible. Games are the perfect playground because they come with built-in scores and clear win/lose signals — one of his favourite past projects was teaching an AI to drive around the track in Mario Kart Wii (finish first, big reward; spend the race driving into a wall, big negative).

The conversation ranges into multi-agent reinforcement learning, where AIs cooperate or compete and can learn games of deception like poker and Risk — including the famous tournaments where AI beat world champions at games long thought to be about "reading people." Natalie, a fan of social-deception and collaboration games herself (she's currently into Blood on the Clock Tower), draws out just how impressive and slightly unnerving that is.

But the heart of Tyler's work is sustainability. His PhD — "computationally efficient high-performance reinforcement learning" — is about achieving top results without the enormous power, water and data-centre demands that big, well-funded labs rely on. The aim is twofold: make the technology accessible to far more people, and make it dramatically greener. With AI's energy and water footprint already a growing concern even at today's relatively small user base, Natalie and Tyler agree that work like his could be a genuine game-changer if usage keeps climbing.

Sophia Dias is 23, from the United States, recorded for this episode from Buenos Aires, and comes at technology from an unusual angle: psychology rather than engineering. Her brand, How We Screen, grew out of a simple, uncomfortable question — what does an intentional relationship with technology actually look like? As a member of Gen Z who has had a phone in her pocket for nearly her whole life, she watched her generation graduate high school, finish college and enter the workforce through a screen, handed devices with "no guide map" and no understanding of what feedback loops, algorithms and infinite scrolling do to attention.

Her central, liberating point is that falling into a 2am doom-scroll isn't a personal failing — these systems were deliberately engineered to capture attention — but that it is still on us to do something about it. She's careful to position herself as pro-human and pro-AI when used intentionally, not anti-technology. How We Screen offers a guided digital detox: currently an ebook (printable and readable analog, fittingly), with an AI-curated detox program in research and development. The goal is to work with your nervous system, build self-awareness, and create space between you and the compulsion loop so you can ask better questions about your own tech use.

Natalie, 45 and a computer-science graduate, brings a sharp counterpoint from the other side of the generational divide: her expectation that kids raised on tablets would "know everything" about technology has proved wrong — digital natives intuitively swipe and scroll, but nobody taught them PowerPoint, email or the breadth of real digital skills, so being a native isn't the same as being literate. The conversation moves through Sophia's path into AI policy, governance and tech ethics, what it's like to study a field moving so fast that even the people building the models can't say what happens next month, and into mindfulness, leadership and the case for deliberately slowing down.

Noor Khizer was a last-minute addition to the show, introduced by Zan that very morning, and turned out to be working on exactly the kind of thing Natalie has started advising her own clients about. His company, VoiceDart, builds bespoke AI voice agents — not an off-the-shelf SaaS product you sign up for and configure yourself, but tailored assistants built around a business's specific operations, with proper hand-holding to get them running. The episode includes a recorded demo of his answering agent, "Valley," which Zan had called earlier to leave a message.

The sweet spot for VoiceDart is tradespeople — roofers, electricians, anyone who's up a ladder or on the tools and can't answer the phone. The agent sits on their existing phone line, captures inquiries and books appointments automatically into Google Calendar, Outlook or whatever they use (and if there's no calendar API, VoiceDart integrates it anyway). It works across the UK — geography is no constraint, as you'd expect from tech.

The most interesting claim is emotional intelligence: Noor says Valley reads the words a caller uses during the transcribed conversation, recognises when someone is angry or upset, and acts accordingly — escalating to a human or booking an urgent appointment. Natalie notes it's the first time a guest has described an AI as emotionally intelligent, and presses on how it's done, how much training went into it (it's a self-learning system that improves from its own mistakes), and — importantly — whether there's a human in the loop. The answer: always.

Alex O'Neill runs Digitastic, a tech consultancy that works with businesses to help them figure out which tools to use, how to use them, and how to keep up when "keeping up" means rechecking what Claude or Gemini can do every Tuesday morning because something will have changed since Monday.

The conversation is an honest account of what tech consulting actually looks like in a period of unprecedented change — not the polished LinkedIn version but the rollercoaster reality of a business that's genuinely dynamic. Alex talks about how she approaches working with businesses that have very different ideas of what they want from technology, why the platform landscape shifts so fast that a recommendation made two weeks ago might already need updating, and what she loves about that pace rather than resenting it.

This is a good episode for anyone who works with clients on tech and has felt the anxiety of recommending something that might be obsolete before the ink is dry on the proposal.

Dan Sagar runs AI workshops and a consultancy helping businesses understand and implement AI tools, with a focus on CRM systems and business automation. But the way he got there is not a straight line. The conversation covers his background — stints that included working on a super yacht and a hotel in New Zealand — and how self-education and a willingness to figure things out in non-traditional environments shaped his approach to tech.

The practical content covers what CRM implementation actually involves (and why so many businesses have a CRM that nobody uses properly), how automation can eliminate the repetitive workflows that drain people's energy, and what it takes to actually run an AI workshop for a business rather than just talk about AI in general terms.

The closing segment on trust in the AI era is worth the price of admission: when AI can generate convincing text, images and video, what does it mean to trust information? Dan's view is grounded and worth sitting with.

Tim Cordell is fresh out of Warwick University with a degree in astrophysics, and Natalie's confession that she knows software but nothing about physics makes this one of the more openly curious episodes of the show. The conversation starts with how Tim got into physics (a maths teacher who left under difficult circumstances, a few months in France, coding games with his dad on Scratch) and moves into the genuinely interesting technical territory.

LiDAR — the laser-based sensing technology at the heart of most autonomous vehicle systems — gets a proper explanation. Bit-flips are even more interesting: the phenomenon where high-energy cosmic rays can spontaneously flip a bit in memory from 0 to 1 or vice versa, which is usually not a problem on your laptop but becomes genuinely consequential in safety-critical systems. For a driverless car making split-second decisions, a single bit-flip in the wrong register is the kind of edge case that keeps engineers up at night.

The conversation is a good reminder that the physics behind cutting-edge tech is fascinating, and that astrophysics graduates end up thinking about these things in ways that pure software engineers often don't.

Insider Media is a national B2B media and events organisation focused on privately-owned and owner-managed businesses, predominantly those up to around £500m turnover (though with some much larger clients). Alan Lindstrom runs their South Coast presence, which includes the Tech & Innovation Awards, property events, the Hampshire business community, and two flagship rankings: the Solent 250 (top privately-owned businesses in the region by turnover) and the Growth 100 (fastest-growing businesses up to £25m).

The conversation covers what those rankings actually capture and what they miss, how Natalie immediately pushes back on turnover as the primary measure, and what the Tech & Innovation Awards are looking for — the kinds of organisations and individuals that represent what's really happening in the regional tech scene. Alan's view from running these events gives him an unusual vantage point: he sees a large cross-section of the business community and has a good sense of where momentum is building and where it isn't.

Matt Kollat brings an enthusiast's depth to the wearable technology conversation. The show opens with exoskeletons — the medical-grade suits that are helping people with paralysis and mobility conditions walk again — and what it means that this technology is getting smaller, cheaper and closer to consumer-grade.

The subscription model discussion is where the conversation gets most interesting: wearable devices are increasingly just the hardware, with the real value locked behind recurring data subscriptions. Matt talks through the health data angle (what your smartwatch actually knows about you), the specific research Samsung is doing on detecting early signs of dementia through continuous biometric monitoring, and the form factor debate — why the wrist won the early wearables war and whether that's the right place for health sensors long-term. Strava and the social/platform dynamics of fitness data round out the episode.

Matt also mentions his own podcast — worth following up if you want more.
