    The BritChips Podcast: Kahu SiliconBio - Pivoting to a Patch

    Anthony Miller speaks with Dr. James Flewellen, co-founder and CEO of Kahu SiliconBio, about the company’s £1.2 million SPRIN-D funding and its shift from environmental sensing toward continuous hormone monitoring for women’s health. The conversation explains the underlying microbial electronic interface, why the pivot is more of a natural extension than a reset, and what the team plans to deliver over the next year. This podcast is also available on the BritChips YouTube channel and in audio form on Apple Podcasts and Spotify. Key topics * James Flewellen explains Kahu SiliconBio’s core technology:a microbial electronic interface that combines living molecular machinery with an integrated circuit chip to turn biological responses into quantitative electronic data. * Why microbes are useful as sensors:they can detect trace molecular changes in aqueous environments because they have evolved for billions of years to sense their surroundings with extreme sensitivity. * The technology platform is broader than water monitoring:James says the same sensing approach can work in biological fluids such as urine, saliva, blood plasma, and interstitial fluid. * The shift into women’s health was driven by opportunity and fit:Kahu saw a SPRIN-D challenge for continuous hormone monitoring, and the application aligned with work they had already begun on estrogen sensing. * The funding process moved very quickly:Kahu applied at the end of June, pitched in Leipzig a week later, and received confirmation shortly after, with the programme effectively already underway. * The team is scaling up:Kahu currently has five people, plus advisors and technical partners, and is hiring two to three more R and D scientists. * The first deliverable is a benchtop prototype:by the end of June next year, Kahu expects to produce a device that simulates the fluid flow of an eventual on-body monitor. * The longer-term goal is a smart patch for continuous monitoring:James describes a postage-stamp-sized patch, similar in concept to continuous glucose monitors, that would sit on the skin and process signals wirelessly. * Initial use cases focus on IVF and fertility support:James highlights how continuous hormone monitoring could reduce blood draws and clinic visits during multi-month fertility treatment journeys. * The platform may extend beyond one condition:Kahu’s planned panel includes five hormones, including thyroid hormones, female sex hormones, and cortisol, with potential applications in other biomedical and performance contexts.

    The BritChips Podcast: UKSC - My Vision, My Goal

    Context “I would like to think that at some point ... the UK has reached its goal of being one of the leading semiconductor nations.” This is the vision of Andy McLean, CEO of the newly established UK Semiconductor Centre. Earlier this year McLean was recruited to lead the UKSC, an idea that had been mooted in various government reports over the years to provide a focal point for the UK semiconductor industry. Backed by £19m of government funding, McLean and his team aim to bring together government, universities and the private sector to support key components of the government’s Semiconductor Strategy. In the latest episode of The BritChips Podcast, McLean explains what the UKSC is trying to do, how it will use its funding, and where it can help startups, universities, investors, and government work together more effectively. The UK already has a panoply of organisations, institutions, associations and government initiatives supporting different (and sometimes overlapping) facets of the UK semiconductor industry. For McLean to realise his vision, the challenge for the UKSC is more than connecting the dots, so to speak. It’s also to create visible and accessible pathways for industry players - startups and scaleups in particular - to surmount the many obstacles they must overcome at each stage of their growth in order to reach and exploit their chosen markets. This podcast is also available on the BritChips YouTube channel and in audio form on Apple Podcasts and Spotify. Show Notes (AI gen’ed) * In this episode, Anthony Miller traces the history of the UK Semiconductor Centre from the 2024 government report through the 2025 industrial strategy and into the appointment of Andy McLean as CEO. * Andy shares why he returned to the UK after more than 30 years in the US semiconductor industry, including leadership roles at National Semiconductor, TI, and Analog Devices. * The conversation explains the UKSC mission in one sentence: connecting industry, academia, and government to help the UK semiconductor sector scale. * Andy breaks down the 19 million pound funding package, noting that it is spread across multiple years and is intended as operating and outreach support rather than direct industry investment. * The discussion emphasizes the centre’s role as connective tissue rather than a lead investor, with government acting as a signal and lever to attract private capital. * Andy discusses why the UK’s semiconductor ecosystem is strong on research, heritage, design, and materials science, but weaker on turning those assets into commercial success. * Andy explains the importance of workforce and skills development, from primary school STEM interest through university and postdoctoral programmes. * The AI hardware plan gets a detailed look as an example of policy that combines education, innovation funding, and procurement, with government acting as a lead customer for emerging UK technologies. * The Taiwan mission is used as a practical example of outreach, with UK startups and SMEs meeting major system integrators, manufacturers, and potential customers in a globally important ecosystem. * Andy outlines how the UKSC thinks about startup support as a full journey: university research, spin-outs, early programmes like ChipStart, investment, and then market access and scaling. * A major theme is the role of university technology transfer offices, where Andy sees a need to study equity terms and licensing practices more closely so spin-outs can scale more easily. * The episode closes with a vision for the next five to ten years: preserve the UK’s creative problem-solving strength and get the UK into the global top tier of semiconductor nations.

    The BritChips Podcast: IP Group - The Clue is in the Name

    Show notes (AI generated, ‘natch!) In this episode: Anthony Miller introduces the BritChips Podcast and frames IP Group as a later-stage investor than Parkwalk Advisors, with both firms sitting under the same parent structure. Lee Thornton explains that Parkwalk uses EIS retail capital for very early-stage university spinouts, while IP Group also deploys balance sheet capital and third-party scale-up funds for later rounds. The conversation breaks down typical cheque sizes: * Parkwalk can write smaller cheques and also support larger ones, often starting around half a million and reaching several millions * IP Group balance sheet capital typically starts around three million and can go up to around ten million * Scale-up funds can provide much larger amounts when companies need more capital Lee says IP Group focuses on science and technology businesses with defensible, order of magnitude better propositions, especially in future compute and silicon. They discuss the importance of flexibility across stages, including situations where Parkwalk and IP Group co-invest in the same company. Lee shares that he came into semiconductor investing from a chemistry and investing background, not from chip design, and that he sources deals through universities, tech transfer offices, co-investors, and industry networks. A major theme is fit: Lee stresses that investors are not interchangeable and that founders do better when they understand what a specific fund actually invests in. He says the strongest pitches show evidence, not just ideas: * proof the technology works * peer-reviewed research or patents * third-party validation from corporates or customers * a clear reason the opportunity is commercially meaningful The discussion goes deep on conviction: * conviction in the technology * conviction in the founding team * conviction that the business can get to an exit Lee explains that most first meetings involve one or two founders, though he likes to see a broader senior team of three to four people where possible. Exit planning comes up early. Lee wants founders to think from day one about how investors get their money back, whether through acquisition, IPO, or another liquidity event. He says the firm is patient on timing, with exits sometimes taking five to ten years, often ten to fifteen years, and occasionally longer. The conversation closes on the reality of venture investing in deep tech: most investments fail, the winners must cover the losses, and the goal is to recycle capital into the next generation of companies.

    This is the future of the UK semiconductor industry!

    Each year, the UK Electronics Skills Foundation (UK ESF) offers hundreds of scholarships to students about to embark on an undergraduate degree in electronics and related disciplines at UK universities. The scholarship, which includes a bursary of £4,000 a year, offers students the opportunity for industry placements, a potential stepping stone towards a career in the UK semiconductor industry. Last week I attended the UK ESF Awards event celebrating the latest cohort, and spoke with previous scholars to find out ‘what the UK ESF did for me’, so to speak. And the answer is, ‘a lot’! I also had a quick chat with Katie Wheeler, Emerging Talent Acquisition Specialist at Arm, one of many semiconductor companies that sponsor placements for UK ESF award winners. Keep up the great work! Watch the clip and see if you agree with me that the future of the UK semiconductor industry looks very bright indeed. You’ll be able to hear much more about the critical role that UK ESF plays in nurturing young tech talent when I chat with CEO Stewart Edmonson in an upcoming episode of The BritChips Podcast. Meanwhile, here’s wishing UK ESF scholars (and new social media stars), Kata Lendvai, Sophia Abbott, Myles Beniek, Nichita Condorachi, Stanley Booth and Koshin Khodiyar good luck with their studies and all the very best for a fulfilling career in the UK semiconductor industry.

    BritChips Podcast: Spin-out Funding - A Walk in the Park?

    In this episode Anne shares what makes a spin-out ready for funding, why product market fit matters so much, and why founders need more than great technology. They also discuss the importance of networks, executive support, and knowing when a company is ready for a different kind of leadership as it grows. Key topics * Anne Dobrée’s path from PhD researcher to tech transfer and university commercialization roles at Imperial and Cambridge * How Parkwalk Advisors invests in UK university spin-outs through EIS-backed funds * What the Enterprise Investment Scheme offers investors * Why Parkwalk typically enters at seed stage, with some pre-seed support through university-linked funds * How university researchers usually progress from idea to spin-out and investor conversations * The role of tech transfer offices, accelerators, demo days, and direct outreach * Why Parkwalk does not invest in research projects, only in companies ready to commercialize * What counts as readiness in semiconductors, including tape-out, prototype progress, and use case clarity * Why commercial experience and executive leadership matter as much as technical brilliance * How investors assess founders: conviction, listening ability, and team-building * Why the best founders know what they do not know and invite help early * The importance of product market fit, especially for academic startups with strong technology but unclear buyers * Why fundraising usually takes longer than founders expect and should be planned as an 18 month plus journey * Why exit thinking matters even early on, including acquisition as the more realistic path for many chip companies This is a public episode.
