E371| Hamish Grierson - The Hire We Made 10 Years Too Late

In this interview, Hamish Grierson, co‑founder and CEO of Thriva, explains the company’s at‑home blood‑testing health‑tracker, which turns longitudinal blood data into actionable insights for consumers and B2B partners such as the NHS, Superdrug and Void. He discusses how lowering barriers—making the test painless, fast (results often within 24 hours), and easy to understand—reduces customer anxiety and drives adoption. Grierson recounts the technical and regulatory hurdles of building a centralized lab infrastructure in the UK, describing the process as “banging your head on low beams” for two years. He highlights a long‑overdue hire: a Director of Product Marketing whose storytelling and creative genius will translate data into compelling narratives, a role he says is essential for growth. The conversation turns to venture capital, which Grierson argues is stifling innovation by forcing founders to chase unicorn‑scale returns; he critiques the common “numbers‑game” fundraising advice and advocates a “rifle” approach—targeted, sector‑relevant investors—over a “shotgun” approach. He outlines Thriva’s expansion plan, choosing Germany as the first European market because of white‑space, a B2B‑first strategy, and limited local lab partners. Cost remains the biggest adoption barrier; the company has reduced price by ~25 % and aims for a £20 price point versus the current £140. Grierson also defends the need for a human‑in‑the‑loop (often a doctor) to help users interpret results, even as technology can assist. On a personal level, he shares his own health routine (monthly blood tests, cold plunges, fasting, adaptogens) and admits he is a product user. Finally, he lists influential books—from startup classics like Zero to One and The Hard Thing About Hard Things to fiction such as Dune and Liu Cixin’s Three‑Body Problem—that have shaped his thinking.
