In this episode, I speak with returning guest Dan Olsen, product management trainer, consultant, speaker, and author of The Lean Product Playbook. We go deep into the rise of "vibe coding" and what it means for product teams. Dan has gone deep into vibe coding, is offering training courses in it, and believes it firmly sits within his existing Lean Product Playbook process and supports the Product/Market Fit Pyramid.

• AI shifts the product bottleneck – As AI tools make engineers more productive, the limiting factor increasingly becomes product discovery and decision-making rather than development capacity.
• Product management isn't going away – AI can automate some tasks, but judgement, prioritisation, and making decisions under uncertainty remain core human responsibilities.
• The rise of the product builder mindset – New AI tools allow product managers to prototype ideas directly, giving them a more hands-on way to explore solutions.
• The vibe coding spectrum – AI development tools exist on a spectrum from simple browser-based tools through to full developer IDE integrations, letting teams adopt them at different levels of technical depth.
• Vibe prototyping vs vibe coding – For most product managers, the real opportunity isn't replacing engineers, but quickly generating interactive prototypes that help teams explore ideas before committing to production code.
• Divergent thinking still matters – AI tools often generate a single solution, so teams need to deliberately explore multiple directions and alternatives rather than blindly optimising the first result.
• Prototypes have four key audiences – Early prototypes help clarify ideas for the creator, align the product team, communicate concepts to stakeholders, and gather feedback from real users.
• Context beats clever prompting – The quality of AI-generated output depends far more on the context, requirements, and constraints you provide than on the prompt itself.
• Iteration beats one-shot builds – The real power of these tools comes from rapid experimentation and refinement rather than expecting a perfect result from a single prompt.

On this episode, I speak to Hugo Alves, co-founder of Synthetic Users, about one of the most controversial topics in modern product development: using generative AI to simulate users for research and decision-making. Hugo has a background in clinical psychology and product, and has spent the past three years building a platform that generates synthetic qualitative interviews to help teams reduce risk and make better decisions.

• What Synthetic Users actually is - generating in-depth qualitative interviews with AI-powered "synthetic" participants to help teams reduce risk and accelerate discovery
• Most companies don't do enough, or any, research in the first place, and they need as many tools in their locker to help with the ultimate goal: making great products.
• The pragmatist's view of AI - why Hugo doesn't care whether LLMs are "conscious", only whether they produce useful outputs
• The agentic "swarm" approach - using specialised sub-agents (planners, interviewers, critics) instead of one giant prompt to improve quality and reduce drift
• B2B vs B2C - why synthetic research works well in B2B contexts, and the harder (future) problem of modelling organisational dynamics
• Bias, sycophancy and realism - the technical concerns around LLMs and how to validate responses with pilots and human comparison studies
• How to use synthetic research in practice - filtering ideas, informing human interviews, and treating it as an accelerant rather than a replacement
• "It shouldn't exist" - the moral argument against synthetic users, reacting to UX thought leaders and their objections, and why some of those objections aren't really about evidence

In this episode, I speak with Jessica Hall. Jess is the Chief Product Officer at Just Eat Takeaway, a global leader in the on-demand delivery space. With a professional pedigree that includes leadership roles at UK retail giants like Tesco, Argos, and Sainsbury's, Jess brings a wealth of experience in navigating complex, high-stakes consumer environments. Our conversation delves into the "big idea" of managing a massive three-sided marketplace, balancing the needs of consumers, partners, and couriers while transitioning from a food-centric brand to an "everything delivered" platform.

We cover a lot, including:

• Navigating the Three-Sided Marketplace - Jess describes the Just Eat Takeaway product as a complex ecosystem connecting 60 million active customers with nearly 400,000 partners and a vast network of couriers. The core insight here is that the "product" isn't just an app; it is the seamless orchestration of these three distinct groups, where a failure in one branch inevitably disrupts the value for the others.
• Scaling Global Platforms with Local Nuance - Despite operating a global tech platform, Jess emphasises the importance of "optionality" to respect regional differences, from currency formatting to cultural preferences like cash usage. This approach allows the company to maintain a unified technical infrastructure while remaining flexible enough to adapt when a specific market, like the UK or Canada, leads the way in new category demands like grocery delivery.
• The Power of Customer Closeness - Moving beyond data and reports, Jess advocates for getting "on the ground" to talk to couriers and visit partner restaurants. By understanding the physical realities, such as a busy kitchen staff finding a feature too cumbersome to use during peak hours, product leaders can solve real-world friction that data trends alone might overlook.
• Cultivating Dual-Track Career Paths - Recognising that not every brilliant product mind wants to manage people, Jess champions the value of senior Individual Contributor roles. She highlights that technical and strategic mastery is just as vital as people management, and providing high-level growth opportunities for ICs ensures the organisation retains its most creative and experienced problem solvers.
• Leading Through Influence and Commerciality - Jess argues that the best product leaders act as "first-rate business partners" rather than just a bridge between engineering and the business. By focusing on "win-win" outcomes and deeply understanding commercial metrics like order volumes and market trends, product teams earn the credibility needed to influence strategy at the highest levels.
