- Capsule Corporation
Participated · Seed · Mar 2026
Capsule Corporation develops water-based electric propulsion systems, with its core product WaterCube designed for CubeSat and smallsat platforms. The company is advancing a higher-performance WaterCube+ variant alongside the baseline unit, targeting TRL 5 for WaterCube+ by Q1 2027. Capsule plans an in-orbit demonstration of WaterCube on a SpaceX Falcon 9 in Q4 2026 as a stepping stone to commercial deployment. It aims to enter the market in early 2027 and is investing in a scalable production chain with standardized assembly to serve growing global demand. Financially, the company recently raised 800,000 in a seed round backed by CDP Venture Capital SGR (via Takeoff Accelerator), kopa ventures, Moonstone Venture Capital and business angels. Francesco Marino and Ivan Nizzola are cited as CEO and COO and co-founders involved in driving the company's industrialization and commercialization efforts.
- YOU(th)
Participated · Equity · Feb 2026
YOU(th) Health Tech is a digital preventive-care company that leverages smartphone sensors, computer vision, and machine learning to perform health screenings in under two minutes. By analysing face videos, voice recordings, eye and skin images, typing patterns, and step data, the platform extracts more than 50 digital biomarkers covering cardiovascular, respiratory, cognitive, dermatological, metabolic, mental, and blood health. The approach eliminates the need for specialised hardware, clinic visits, or invasive tests, thereby reducing the time, cost, and friction that deter roughly 60 % of people from regular check-ups. CEO and founder Filippo Nigro positions the service as passive, low-friction prevention that runs “inside” daily life rather than interrupting it. Newly secured capital will be channelled into accelerating product development and enlarging engineering, data-science, and medical-research teams. To date, the company has raised $4.5 million, providing resources to refine its AI models and expand global access to preventive screenings.
- Jack Fertility
Participated · Seed · Oct 2025
Founded in May 2022 in Oxford by Nick Shipley and Lily Elsner, Jack Fertility is tackling the stigma and inconvenience surrounding male reproductive health. Its flagship product, Snip Check™, is billed as the UK’s first fully portable vasectomy test kit: users mail in a preserved sample that remains viable for up to five days, receive results via a companion mobile app, and gain access to supportive communities. The company positions this method as both more convenient and more clinically rigorous than existing at-home or remote fertility tests. With fresh capital secured, Jack Fertility is preparing the commercial launch of Snip Check™ while rapidly developing a complete home-to-lab semen analysis kit. In the longer term, the founders aim to build a suite of data-driven tools that make sperm testing as routine as checking blood pressure. The startup has not yet disclosed revenue or user figures but has attracted early investor and grant support to finance product development and market entry.
- Messium
Participated · Seed · Sep 2025
Messium combines hyperspectral satellite data, crop growth models, and proprietary AI analytics to provide weekly, field-specific nitrogen and crop-health recommendations. Its platform ingests satellite imagery alongside weather, soil, and farm management data to generate actionable fertiliser guidance. The company reports trials across Europe and Australia using more than 13,000 lab-validated crop samples and is delivering results to over 75 farms in the UK and Europe; its trials found over 50% of fields were incorrectly fertilised. Messium says its technology can boost yields, cut input costs and reduce emissions by eliminating fertiliser guesswork. The business recently secured a €3.8M Seed investment to accelerate commercial rollout, scale its data and analytics infrastructure, and grow its team and partner network. Messium plans to expand in the UK, Europe and Australia and is preparing for a Series A to support further international expansion and technology development.
- Luna
Participated · Equity · Oct 2024
Luna is a London-based health and well-being app for teen girls that lets users ask anonymous questions to medical and wellness experts and track periods, moods, skin, sleep and daily habits. The app surfaces expert content in a 'Learn' section and uses AI to automatically field repeat questions so clinicians can focus on new or complex queries. Users receive monthly reports with insights based on their logs and the app nudges healthy habits and prompts medical follow-up when appropriate. Luna operates a freemium model with capped free access and an unlimited plan for €2.99 per month. Since launching a simple version in November 2022, the platform has grown to roughly 100,000 members and nearly 45,000 questions asked. The founders, Jas Schembri-Stothart and Jo Goodall, developed the idea during their MBA at Oxford, presented at TechCrunch Disrupt 2024, and plan to launch in the United States next year.
