- Unfabled
Participated · Seed · Oct 2025
Founded in 2021 by Hannah Samano, Unfabled uses a community-driven R&D approach called Unfabled Labs to identify and validate women’s health needs before launching products. Its Essentials supplement line targets issues such as bloating, cramps, low energy, sleep problems, and stress, and has quickly expanded from an initial 50 Boots stores to 737 locations—a more than 1,000% retail footprint increase. The company combines data insights, scientific backing, and lived experience to create products "by women, for women." Direct-to-consumer traction has translated into retail momentum, earning Unfabled a place in Boots’ Ignite accelerator for trending brands. To date, the startup has secured just over €3.3 million in seed funding, 67% of which comes from female investors, reflecting its mission to improve gender representation in both healthcare and venture capital. Unfabled positions itself as a leading voice in the growing European femtech sector, aiming to build a broader category of accessible, consumer-focused women’s health solutions.

- Biotangents
Led · Equity · Nov 2024
Biotangents has developed a cost‑effective on‑farm molecular diagnostic that returns highly accurate results in less than two hours, enabling informed treatment decisions for dairy farmers. The device sends data to the farmer’s phone and can integrate with farm management systems, vets, and milk processors. The technology is aimed at reducing unnecessary antibiotic use (estimated unnecessary treatment in up to 40% of cases) and addressing antimicrobial resistance while improving herd health, productivity, and sustainability. Biotangents is focused on next‑generation diagnostics for the animal health sector, with potential future applications in human healthcare and environmental monitoring. The company announced a £2.3m investment round to support development and commercialisation and will commence on‑farm trials across the UK and internationally next year. Biotangents was founded in 2015 as a University of Edinburgh spinout and is headquartered at the Pentlands Science Park near Edinburgh.

Leadership includes founders Dr Andy Hall-Ponselè and Lina Gasiūnaitė, with Fiona Marshall as CEO, Ian Hamilton as Chairman and Ross McDermid as Director of Commercialisation.

- 1inhaler
Participated · Equity · Nov 2023
1nhaler, headquartered in Edinburgh, is building a novel pop-up dry-powder inhaler (DPI) made predominantly from eco-friendly cardboard. The single-dose, disposable device folds from a credit-card shape into a three-dimensional inhaler through a patent-protected membrane system, tackling the cost, usability, and environmental drawbacks of traditional plastic inhalers. Performance data from its lead product matches leading multidose DPIs, and the platform can be tuned to deliver a range of dry-powder drugs for conditions such as asthma, COPD, influenza, and Parkinson’s. Recent funding will support the manufacture of clinical material, development of large-scale production processes, and preparation of a first Marketing Authorisation Application targeted for late 2027. The company has secured manufacturing partnerships with Upperton for clinical supply and Harro Höfliger for commercial scale-up. Founders Don Smith and Lisa McMyn have assembled an experienced leadership team, including former GSK and AstraZeneca executives, to steer the product toward commercialisation. 1nhaler is actively engaging potential pharmaceutical partners to bring both new and existing inhalable therapies to market more sustainably and cost-effectively.
