    Reimagining groceries for the everyday shopper, with Andy Ellwood, Founder & CEO of Stretch

    This week on Tech Can’t Save Us, host Paul David is joined by Andy Ellwood, founder and CEO of Stretch, the first shopping intelligence platform built to help families save money and make smarter grocery decisions. Andy’s career spans private aviation, startups acquired by Facebook and Google, business development at Waze, and years spent coaching top founders and now he’s bringing that eclectic experience to one of the most universal, everyday challenges: buying groceries. Andy explains why the grocery industry is overdue for reinvention. Despite rising prices and endless choices, shoppers still lack the information parity they now expect in categories like travel, real estate, and healthcare. Stretch solves this by turning individual shopping lists into collective intelligence: shoppers enter their weekly items, and the app instantly shows which nearby retailers offer the best total basket price, often saving families $20–$40 per week. The conversation explores Stretch’s early traction, from thousands joining the waitlist to viral TikTok growth, and how the team is building a massive data moat by connecting cross-retailer pricing in ways the industry never had to before. Andy shares how AI and “agentic commerce” will transform shopping, why Stretch centers dignity and agency for families navigating rising costs, and how his background at Waze shaped his approach to scaling community-driven products.

    Rethinking SME Finance with Dr. Serge Santos, Founder & CEO of Funding Alternative Group

    This week on Tech Can’t Save Us, host Paul David is joined by Dr. Serge Santos, entrepreneur, investor, and award-winning leader known as The Business Physicist. After deploying over $1 billion in capital during his investment banking and hedge fund career and achieving a multi-million-dollar exit with his previous company, Serge is now tackling one of the UK’s most persistent economic challenges: SME access to finance. Through Funding Alternative Group, Serge and his team are reimagining how small businesses secure funding when traditional banks say no. Since 2022, the platform has deployed £8M in SME loans and £18M in invoice finance, offering fast, flexible, and human-centred lending for businesses often shut out of conventional systems. Serge explains how open banking allows Funding Alternative to assess risk using real-time data rather than outdated statements, enabling decisions in hours instead of weeks when clients face challenges. The conversation explores the company’s biggest growth opportunities, the complexities of raising institutional capital responsibly, and how Serge applies his “business physicist” mindset to simplify complexity through rational, systems-based thinking. He also shares why culture is his “ultimate multiplier of success,” and why discipline, transparency, and trust sit at the heart of every funding decision.

    Quantum security and the fight against counterfeiting with Rob Young, Co-Founder & CSO of Quantum Base

    This week on Tech Can’t Save Us, host Paul David is joined by Professor Rob Young, Co-Founder & Chief Science Officer of Quantum Base, a pioneering deep-tech company using quantum physics to authenticate products and stop counterfeiting at the atomic level. Rob explains how Quantum Base’s flagship technology, Q-ID, a tiny, printed tag containing “atomic-level uniqueness,” delivers provably secure authentication that’s impossible to clone and can be verified by anyone using a standard smartphone. With over half a billion Q-ID tags already produced, the company is tackling a global counterfeiting problem worth $2.8 trillion, including counterfeit medicines that cause more than 1 million deaths annually. The conversation explores Quantum Base’s journey from university research to becoming a publicly listed company on London’s AIM market, raising £4.8M to scale its technology across industries, from luxury goods and government documents to pharmaceuticals and critical supply chains. Rob also reflects on his 20-year academic career across Cambridge, Tyndall, and Lancaster, how a breakthrough in his PhD work inspired the origins of Q-ID, and why he believes quantum security must be accessible, affordable, and deployable at global scale.
