- Reformed
Participated · Series A · Jul 2026
Founded in 2024 by Neil Saada and Neil Marrakchi, Reformed sells pouches of instant specialty-grade arabica coffee and ceremonial matcha that include 21 vitamins and minerals, functional mushrooms (lion’s mane and chaga) and either 15g collagen or 5g creatine. The products are offered caffeinated or decaf (coffee) and come in multiple flavors; they can be prepared hot or cold and mixed with milk or water. Reformed operates primarily on a direct-to-consumer subscription model with pricing starting at £39.99 per month, and it also sells branded accessories and has selective retail presence (including Selfridges). The company has scaled profitably to $70 million in annual revenue within two years and reports particularly strong growth among health-focused consumers in central London. Reformed plans to expand into the U.S. in the third quarter and intends to prioritize controlled, quality-focused growth rather than mass retail distribution.
- Meatly
Participated · Series A · May 2026
Meatly was launched in 2022 and develops cultivated meat products, having achieved regulatory authorization in 2024 and sold the world’s first cultivated pet food in 2025. The company reports major cost reductions—its chemically defined protein-free medium reached £0.22 per liter in 2024 and it reduced bioreactor costs by about 10x in 2025—which it says underpin commercial viability. Meatly plans to build a 20,000-litre bioreactor facility in London, described as Europe’s largest of its kind, with fit-out beginning immediately and product releases expected in 2027. Financially, the company has raised £17.4 million to date, comprised of a £7 million seed round (led by Agronomics and Pets at Home) and the £10.4 million Series A announced here. Meatly frames these technical and regulatory milestones as the foundation for scaling commercial output and entering broader markets by 2027.
- Shellworks
Participated · Series A · Mar 2026
Shellworks is a London-based biomaterials company founded in 2019 that creates and manufactures Vivomer, a plastic-like material produced by fermenting second-generation feedstocks such as used cooking oil. Vivomer performs like traditional plastic during use but biodegrades after disposal, offering brands a sustainable packaging option. The company has proven cost competitiveness with materials like aluminum and glass even at a relatively small production scale of roughly five million units, removing a key barrier to adoption. Shellworks is targeting the wellness sector first and plans to build a global production network, including blow-moulding facilities in the UK, Europe and the United States, to shorten supply chains and lower carbon footprints. The firm will also develop mass-market partnerships to accelerate market penetration. Longer term, management expects economies of scale to further improve its pricing advantage over petroleum-based plastics.
- Tewke
Participated · Equity · Feb 2026
Founded in 2020 in London, Tewke develops Tap, a smart light-switch–sized device that installs in minutes and works in homes lacking a neutral wire, covering over 90% of UK housing. Tap’s nine on-board sensors feed data into the firm’s proprietary Tewke OS and the recently introduced TewkeAI framework, enabling contextual, AI-driven optimisation of lighting, heating and other electrical loads to align consumption with time-of-day tariffs. The company designs and patents its own hardware, firmware and operating system in-house. Beyond energy savings, Tewke aims to create a broader intelligent, user-centred living environment through neuro-symbolic AI systems now in development. The new capital will fund go-to-market execution and an expanded engineering team. Tewke’s growth is further supported by non-equity grants from Innovate UK. No revenue or user figures were disclosed.
- KluraLabs
Participated · Series A · Feb 2026
Cambridge-based KluraLabs is a sustainable packaging company whose proprietary stickers and films slow the spoilage of fresh produce and baked goods without altering taste, odour, texture or appearance. The technology is designed to fit seamlessly into existing food packaging, improving logistics and reducing waste across the food-and-beverage supply chain. In retailer trials – including an early rollout with M&S – the solution has significantly extended the shelf life of berries, grapes and baked goods. Founded in 2020 by Matin Mohseni and Reza Saberi Moghaddam and led by CEO Charlie Hobhouse, the company sees its innovation as a way to save households and businesses money lost to food waste. The fresh capital will be used to scale manufacturing, broaden supermarket deployments and expand the R&D pipeline for additional freshness-preserving materials. KluraLabs’ longer-term goal is to revolutionise global food systems by embedding its freshness technology across multiple product categories. No revenue or user figures were disclosed in the article, but the business has now secured £7.7 million in total funding to date.
