• Circular11

  Participated · Equity · Jun 2026

  Circular11 develops manufacturing technology and products made from low-grade plastic waste, producing composite lumber used for fencing, furniture and landscaping for construction and estates. Its process involves collecting problematic plastic streams, shredding and chemically profiling materials, using machine learning to determine optimal formulations, conducting in-house strength testing, and extruding finished plastic lumber while tracking feedstocks and carbon via a digital operating system. The company positions its composites as lower-carbon, longer-life alternatives to timber and aims to divert plastic from incineration and landfill. Founded in 2021 and based in Dorset, Circular11 set up a full-scale recycling and manufacturing facility following a 2023 €578k raise and now intends to scale manufacturing with the proceeds of its €2.7 million round. It aims to recycle about 10,000 tonnes of low-quality plastic over the next two years and to create a scalable recycling technology that can be deployed globally.

• Caudal Energy

  Participated · Equity · May 2026

  Caudal Energy designs an oscillating foil "Caudal Generator" inspired by marine mammal tail fin hydrodynamics to harvest predictable tidal power using a modular, surface-mounted architecture. Its fin-based platform is engineered to operate efficiently in mid-flow tidal locations (peak flows above 3 knots), expanding the range of viable sites compared with conventional turbine systems that require higher peak flows. The modular design aims to simplify installation, lower maintenance and operational complexity, and reduce levelized cost of energy to be competitive with established technologies such as offshore wind. The technology has reached Technology Readiness Level 5 and is entering full-scale testing at Strangford Lough, with a targeted first commercial deployment in 2028 to reach TRL8. Caudal was founded in 2024 (originally Porpoise Power) based on breakthrough hydrodynamic research from the University of Oxford and is advancing commercial partnerships across utility, industrial and distributed energy markets.

• Semarion

  Participated · Equity · Mar 2026

  Semarion is a University of Cambridge spin-out building the SemaCyte platform that combines materials engineering, microfabrication, and cell biology to enable adherent cells to be used as barcoded, assay-ready, automation-compatible reagents. Its technology lets researchers multiplex cell models, increase throughput, and generate richer datasets within existing laboratory workflows. The company reports adoption by several global pharmaceutical organisations, including top 10 pharma companies, and is running pilot programmes in the US and Europe. Semarion has collaborations with life sciences tools providers to integrate its platform into imaging, analysis, and automated liquid handling workflows. Financially, Semarion has raised $2.89 million in 2022 and an additional $3.8 million in the latest round to fund manufacturing scale-up, commercial growth, and expanded field support.

• NavLive

  Participated · Seed · Dec 2025

  NavLive is a UK reality-capture technology company spun out of robotics research at the University of Oxford. Its core product is a handheld LiDAR scanner that fuses edge-based AI with SLAM to deliver instant 2D and 3D site data, RICS-grade 1:100 surveys, and direct scan-to-BIM outputs. The system has already been deployed on live projects by engineering and construction firms such as Jacobs, AtkinsRéalis and Mace. NavLive employs 15 people and operates from offices in London and Oxford under CEO Chris Davison and CTO Dr. David Wisth. The company recently closed a £3.3 million seed round and previously secured a £700,000 Innovate UK grant, providing capital to scale its team and accelerate product development. With the new funding, NavLive plans to expand adoption of its technology across the wider built-environment sector.

• Gardin

  Participated · Seed · May 2025

  Gardin builds an optical photosynthesis sensor combined with AI to measure crop photosynthesis in real time, providing growers early insight into plant health and development. The system is deployed across more than 20 crop species, from algae to tomatoes. Led by CEO and founder Sumanta Talukdar, the company is based in Oxford, UK. Gardin plans to use the new funding to enhance its platform and expand its commercial team to grow its customer base across continents. The article reports a $4.5M Seed 2 financing, which represents the company’s latest outside funding. No revenue or user metrics were disclosed in the article. Gardin combines remote optical sensors with machine learning to provide growers detailed, non-destructive measurements of individual-plant physiological performance. Its sensors can detect growth anomalies such as underwatering days earlier than expert agronomists, enabling faster corrective action. The product targets controlled-environment agriculture — greenhouses and indoor/vertical farms — where light and temperature can be regulated. Gardin plans to expand its product lineup with crop forecasting and nutritional density mapping, ramp up production capabilities, and continue marketing across Europe and North America. The company has seen strong interest from the sector and reports a steady sales pipeline. Since launching in 2020, Gardin has raised a total of $12 million, including the recent seed round. Gardin develops optical phenotyping hardware and accompanying analytics software to measure and monitor nutritional value of food across the supply chain. The company uses multispectral data fusion, remote sensing and computer vision to capture biochemical signatures and quantify plant physiology and compound density with high fidelity. Its full‑stack product is designed to run like an OS in the background, integrate with existing producer architectures, and optimise growing environments to lower costs, reduce carbon footprint and cut waste. Gardin targets both traditional agriculture and controlled environment agriculture (CEA) and aims to become a new food‑production gold standard. The startup has partnered with crop and plant physiologists and phenotyping experts to identify key biochemical mechanisms for different crops. Gardin has secured pilot trials with supermarket chains, food producers and vertical farms that are ready to go live early this year, and recently raised external pre‑seed funding.
