• 3282: Fighting Waste with AI and Community at Olio

  What does it take to turn a moment of frustration into a global mission to tackle waste? At the AWS Summit in London, I sat down with Tessa Clarke, co-founder and CEO of Olio, to explore how a single idea born on a snowy Swiss street evolved into a powerful tech platform reshaping how communities think about consumption, sharing, and sustainability. Tessa shared her personal journey, from growing up on a farm where food waste was unthinkable to climbing the corporate ladder before walking away to co-found Olio. That decision came after she was told to throw away perfectly good food while moving house, a moment that sparked an idea and a deeper calling. What followed was years of research, a grassroots WhatsApp experiment, and ultimately, the creation of an app that now connects millions of users worldwide. In our conversation, we explored how Olio uses technology to drive real-world change. Tessa explained how AWS has been a foundational partner since day one, helping Olio scale sustainably without compromising its values. She also gave an inside look at how AI is integrated thoughtfully across their operations, from assisting users in listing items faster to detecting potentially unsafe or inappropriate listings before they go live. What stood out is how intentional Tessa and her team have been in making AI serve the mission, not distract from it. Whether it’s reducing friction within communities or using automation to offset operational challenges, every tech choice is aligned with their goal: to build a waste-free world. We also discussed how AI is helping them break the traditional link between headcount and impact, paving the way toward profitability while staying people-focused. As Olio aims to reach a billion users by 2030, this episode is a reminder of what happens when purpose and technology meet. Tessa’s story offers a compelling blueprint for founders, technologists, and anyone looking to use digital tools to solve human problems. How can a simple act of sharing create ripple effects across the world, and what role will technology play in scaling that vision responsibly?

• 3281: From Cambridge to Call of Duty: The Rise of Real Holography

  Holography has long lived in the shadow of science fiction, but what happens when it’s finally real  and ready for the consumer market? In this episode recorded at Tech Talks Daily, I sit down with Darran Milne, co-founder and CEO of VividQ to unpack what sets true holography apart from the gimmicks. With a background in quantum physics and years of technical leadership, Darran cuts through the noise around immersive display technologies and explains how VividQ is building real holographic experiences — not tricks of the eye, but accurate 3D projections that replicate how we naturally see the world. Darran walks us through the technology powering their recent demo with Call of Duty, showing that VividQ’s tech isn’t just theoretical. It runs on today’s hardware and can convert existing 3D content into holograms without access to the original source code. That changes the game for entertainment, but it’s only the beginning. We explore where else this could lead: head-up displays in cars that genuinely blend digital directions into the driver’s view, medical devices that eliminate the need for separate testing rooms, and even the idea of holography replacing traditional screens entirely. Darran doesn’t just speculate on the future — he outlines a practical, layered rollout strategy, identifying the industries where the technology can scale first. This isn’t about chasing hype. It’s about thoughtful engineering and commercial execution. If your business touches gaming, automotive, spatial computing, or XR, this conversation shows why holography may be closer than you think — and how VividQ plans to put it in front of you. Could your next screen be light itself?

• 3280: Yobi and the Future of Ethical AI at Scale

  What if companies could tap into powerful behavioral AI without compromising user privacy or crossing legal lines? In this episode of Tech Talks Daily, I sit down with Frank Portman, CTO of Yobi, to explore how his team is building foundation models grounded in real user behavior, backed by ethically sourced and consented data. Frank shares how Yobi is taking a distinct approach. They're not building large language models or racing to dominate generative AI headlines. Instead, they're focused on data integrity, transparency, and security from day one. With a strategic partnership with Microsoft Azure, Yobi delivers models that run directly within a customer’s environment. That means privacy is preserved, data stays protected, and companies still benefit from intelligent, adaptive systems. We unpack how Yobi avoids risky use cases like financial underwriting and healthcare, how their models are trained to avoid demographic bias, and why they actively reward systems for being bad at guessing personal traits. This isn’t just about compliance. It’s about designing products that work better because they’re built responsibly. Frank also opens up about Yobi’s internal culture, his belief in first-principles thinking, and how empowering engineers to "place bets" drives innovation. He offers insight into what the AI industry must learn quickly from recent missteps, including data misuse and growing public skepticism. If you're exploring AI solutions and wondering how to build or buy systems that scale without cutting ethical corners, this conversation delivers clarity, honesty, and direction. Are you ready to rethink what responsible AI should look like inside your company?

• 3279: How Rewriting the Code is Empowering Women in Tech

  When we talk about the future of technology, it is easy to focus on the tools, trends, and innovations that dominate headlines. But behind every breakthrough is a human story, and behind every system are individuals navigating an industry that has not always welcomed them equally. That is why I sat down with Sue Harnett, founder and CEO of Rewriting the Code, to learn more about the real work being done to support and elevate women in technology. What followed was a wide-ranging conversation that brings clarity to an often-overlooked challenge and offers insight into what real change looks like. Rewriting the Code is more than a community. It is a global network of over 35,000 women who are united by shared goals and driven by the ambition to create a more inclusive tech industry. Sue shared the origin of the organization, born from her own experiences of feeling out of place in elite academic environments, and how that shaped her commitment to building a culture where young women could grow, thrive, and most importantly, feel like they belong. Today, RTC is impacting lives across the globe with programs that span mentorship, career development, technical education, and real-world support. What stood out was the way RTC moves beyond symbolic gestures and instead provides practical pathways. We explored the launch of targeted initiatives like Rewrite AI and Rewrite Cybersecurity, which aim to prepare women for high-demand areas in the industry. We also discussed the Black Wings program, built specifically for Black women in tech, who represent just two percent of the industry workforce. Through focused community-building and peer support, these programs help dismantle systemic barriers that often go unaddressed. In a time where many companies are retreating from public conversations about diversity due to political pressure, Sue’s work feels more relevant than ever. She spoke candidly about the fear she’s seeing in boardrooms, the erosion of public DEI commitments, and the quiet but continued support from leaders who still believe in building inclusive workplaces. Her message to companies was simple: inclusion must be intentional, visible, and connected to the lived experience of the people it is meant to support. What this episode reveals is not only the importance of creating opportunities, but also the power of belief. The belief that women belong in every corner of the tech world, and that with the right community, mentorship, and visibility, they can redefine what leadership looks like. So how is your organization showing up for underrepresented talent in tech, and what will it take to turn good intentions into lasting impact?

• 3278: Zensar Technologies on the Real ROI of AI-Powered IT Services

  When we talk about the future of IT services, the conversation often revolves around the potential of AI and automation. But what does that really mean when applied at scale, across legacy infrastructure, evolving customer expectations, and real-world operational challenges?  In today’s episode, I sat down with Manish Tandon, CEO of Zensar Technologies, to explore that very question. What emerged was a refreshingly pragmatic take on a space often overwhelmed by buzzwords. Manish leads a global organisation that's helping some of the UK’s biggest businesses not just integrate AI, but rethink the foundation of their IT strategies. We discussed how Zensar is combining automation with a philosophy they call “experience-led everything,” a human-centric approach that puts users, not systems, at the centre of transformation. Through this lens, he explained how seemingly simple shifts like applying AI to reduce technical debt or drive internal engagement can lead to significant performance gains and improved outcomes across entire organisations. What I found particularly powerful was how Manish challenges the language around AI. He sees today’s wave of generative and agentic AI as an evolution of long-standing automation principles, not a reinvention. That mindset is helping clients cut through the noise and focus on impact, such as faster delivery cycles, measurable productivity boosts, and tools that empower rather than replace human potential. We also touched on the ethical implications of AI, the nuances of implementation across different geographies, and the value of responsible AI governance at the application level, not just in principle. If your business is looking to adopt AI in a way that scales sensibly while delivering lasting value, this episode offers insights you won’t want to miss. So how are you preparing to balance automation with empathy in your IT strategy, and are you building for systems or for people?
