- BioScout
Led · Seed · Aug 2026
BioScout builds an AI-powered early warning platform that captures and analyzes airborne crop pathogens before visible field damage occurs. Its automated hardware uses an active wind vane to trap airborne particles onto an internal adhesive tape, which is then positioned beneath a high-resolution robotic microscope for imaging. Proprietary machine learning models analyze the physical morphology of over 40 distinct agricultural threats, including Alternaria and Downy Mildew. The company currently operates a global automated sensor network of about 250 units and plans to scale to 1,000 active deployments by 2029. BioScout intends to expand commercially across Europe and enter the Brazilian soybean market. The company is led by founder and CEO Dr. Lewis Collins and recently raised A$6.75m (US$4.8m) in Seed funding.
- Aptimiz
Participated · Equity · Jul 2026
Aptimiz develops a data-collection tool for agricultural operations that aims to optimize the working time of farm operators. The company is based in Angers and has positioned itself as a specialist in improving farm labor efficiency. Following a prior capital increase in 2023 that included Demeter and Asterion, Aptimiz raised €1.4M in the most recent round to support international expansion. Investors in the new round include Demeter (Vitirev Innovation), Asterion, Kinvest, Marco&Co and the réseau sarthois. The company intends to deploy the funds primarily to internationalize its product and scale its commercial presence abroad.
- Jay & Joy
Led · Equity · Mar 2026
Founded in 2015 and based in Lacroix-Saint-Ouen, Jay&Joy makes cashew-based artisanal vegan cheeses—such as Brie/Camembert-style Joséphine and Roquefort-style Le Jeanne—using rigorous fermentation and ripening processes. After a 2023 production halt and receivership linked to listeriosis cases, the company was acquired by an investment consortium and resumed production under CEO César Augier. Jay&Joy owns the Les Nouveaux Affineurs brand following a 2024 acquisition, expanding its portfolio of alternatives including Camembert and cream cheese. The company is present in 10 European countries and launched in UK independent stores in 2025; Les Nouveaux Affineurs is in about 1,000 French stores with a target of 2,000 by the end of 2026. Jay&Joy grew sales by 90% in 2024 and plans to scale manufacturing to produce over three million plant-based cheeses annually by 2027.
- Amatera
Led · Seed · Mar 2026
Founded in 2022 by Omar Dekkiche and Lucie Kriegshauser, PhD, Amatera is developing a high-throughput breeding platform that screens individual plant cells in culture to identify desirable genetic variations before regenerating them into full plants. This approach eliminates the costly and time-consuming step of growing all candidate plants, cutting the development cycle for new varieties of perennial crops such as coffee and wine grapes from decades to a few years. The company induces spontaneous, non-GMO genetic variation and then sequences and analyzes the resulting cell lines with robotics and AI to pinpoint traits like disease resistance, climate resilience, and flavor. Early candidates include a “Robustica” coffee combining Robusta resilience with Arabica taste, a naturally caffeine-free Arabica line, and wine grapes resistant to downy mildew and black rot. Amatera licenses finished varieties for perennial crops while offering its platform to seed companies working on annual row and vegetable crops. Proceeds from its latest funding will help scale the technology and secure additional commercial partnerships.
- Ilion
Led · Seed · Mar 2026
Ilion Water Technologies is building a next-generation water desalination and purification platform that replaces energy-intensive, high-pressure systems with a patented, highly charged membrane that operates on just a few volts of electricity. The approach enables pressure-free, chemical-optimised filtration, promising lower costs and energy usage compared with traditional reverse-osmosis solutions. Fresh capital will fund the expansion of its team of scientists and engineers and support the company’s move from ENS-PSL research laboratories into industrial environments. Near-term plans include completing technological scale-up and launching field trials with industrial partners to validate robustness in real-world conditions. The company has secured €3.8 million to date, including €1.3 million in non-dilutive grants, providing runway for these milestones. No commercial revenue or user metrics were disclosed in the announcement.
