Another week, another cohort of founders raising capital across European impact.
Circular industry led the week, from VoltR's €22m to give lithium battery cells a second life to Reclinker's £10m Series A for cement recovered from demolition waste.
Food and farming made up three of the ten deals. Several rounds also drew on public money, from Bpifrance and Germany's Rentenbank to the Swiss Technology Fund.
Impact Loop has picked out the deals that caught our eye, together with their backers.
VoltR – €22m round
About: VoltR collects used lithium batteries, tests each cell and reuses the healthy ones in new batteries matched to their remaining performance. The batteries go into power tools, e-bikes and scooters, home automation and mobile storage.
The company was founded in 2022 and is led by CEO Maxime Bleskine. Its factory is in Verrières-en-Anjou, near Angers in western France.
VoltR says it has put more than 20,000 batteries on the market and employs about 40 people.
Investors: Bpifrance's SPI fund, which it manages for the French state under the France 2030 plan, and Decathlon PULSE, the sports retailer's investment arm, put in €16m of equity. The remaining €6m comes as grants under the French state's Première Usine programme.
What the money is for: VoltR will double the size of its factory, automate production and develop its cell testing technology. It aims to increase production capacity sixfold within two years and create about 40 jobs.
Edonia – €15m round
About: Paris-based Edonia turns spirulina, a microalga usually sold as a green powder, into a protein-rich grain. Food makers and caterers use it in place of meat, cheese or fish.
Pierre Mignon, Hugo Valentin (CEO) and Nicolas Irlinger founded the company in 2023, and developed its process with AgroParisTech.
Edonia says it holds €30m in pre-orders across around 20 contracts, and has delivered first orders to catering group Newrest and weight-loss specialist Aliive. It claims its product has a carbon footprint up to 27 times lower than meat.
Investors: SWEN Blue Ocean 2, the ocean fund of SWEN Capital Partners, led the round with Asterion Ventures and EIT Food. Asterion also led Edonia's €2m round in 2024.
The total includes non-dilutive funding from Bpifrance under France 2030, and bank financing. The split was not disclosed.
What the money is for: Edonia will set up a production facility at an existing shared site in France. It will also grow sales to food service customers in Europe, Japan and the US.
Reclinker – €11.5m Series A
About: Reclinker recovers old cement paste from demolition waste and feeds it into the electric arc furnaces steelmakers already use to melt scrap. The furnace turns out recycled steel plus a slag that can replace clinker, the key ingredient in cement, without kilns, quarried limestone or fossil-fuel heat.
The method was developed at the University of Cambridge and published in Nature. The company is led by CEO Bill Yost.
Reclinker says it has produced thousands of tonnes at 7 Steel UK's site in Cardiff and made its first commercial sales. It claims the process halves emissions compared with conventional cement.
Investors: Clean Growth Fund and AP Ventures co-led the oversubscribed £10m (€11.5m) round. New investors Development Bank of Wales and Kibo Invest joined existing backers Zero Carbon Capital and Cambridge Enterprise.
What the money is for: Reclinker will scale up production in Cardiff and create jobs in South Wales. It will also prepare to replicate the process at further sites in Europe and the US.
UniSieve – €7.7m Series A
About: Zurich-based UniSieve makes membranes that act as molecular sieves, separating gases in chemical plants without the heating and cooling conventional methods need. They are built from metal-organic frameworks and zeolites, materials full of tiny pores of a precise size.
Samuel Hess (CEO) and Elia Schneider founded the company at ETH Zurich in 2018.
UniSieve says it has reached pre-commercial maturity in two uses, olefin production and capturing CO2 at industrial sites. Polish chemicals group Qemetica is testing one of its carbon capture units.
Investors: Orano Venture Fund, managed by Supernova Invest, led the $9m (€7.7m) round. Amadeus APEX Technology Fund, Founderful, Zürcher Kantonalbank and Guenat Holding also took part, bringing total funding to $25m.
What the money is for: UniSieve will scale up in its existing markets and move into further industrial applications.
hexafarms – €4.8m seed
About: Berlin-based hexafarms helps greenhouse growers see what is happening in their crops. Wireless sensors track climate, irrigation and light every five minutes, while cameras and scouting robots check every plant daily for pests and disease.
AI models turn that data into rolling harvest forecasts. Growers pay a subscription, and hexafarms keeps ownership of the hardware.
David Ahmed (CEO), Felix Kirschstein and Huijo Kim founded the company in 2021. It says it works with more than 50 growers in 13 countries, including fruit and vegetable group SanLucar.
Investors: Ananda Impact Ventures and Green Generation Fund co-led the round. New investors Grey Silo Ventures and better ventures joined existing backers Speedinvest, Mudcake and Techstars.
Separately, hexafarms secured a start-up grant and a subordinated loan of up to €800,000 from Rentenbank, Germany's agricultural development bank.
What the money is for: hexafarms will develop its sensing and scouting technology, and expand across the DACH region, Benelux and Spain.
Rodinia Generation – €4m round
About: Copenhagen-based Rodinia runs automated production lines, which it calls O-factories, that make clothes on demand close to where they are sold. The machines adjust to each garment's digital design, so a single line can switch between styles in short runs.
Trine Young founded the company in 2017 and is its CEO. A pilot line in Copenhagen has produced for brands since 2021, including Henrik Vibskov and Klaus Samsøe.
Rodinia says its process uses no water and cuts emissions by about 40 per cent for an average garment.
Investors: Vitamin°C, a Swiss-US venture fund, led the round. Existing investors Climentum Capital and EIFO, Denmark's export and investment fund, also took part.
What the money is for: Rodinia will open its first commercial-scale O-factory in Portugal, expected to start production in early 2027.
Neela Biotech – €2.4m pre-seed
About: Cambridge-based Neela Biotech adds AI-designed microbes to existing biogas plants. The microbes turn food, farm and forestry waste into fatty acids, which can be refined into sustainable aviation fuel (SAF).
Deepanshu Singh (CEO) and Friederike Nintzel founded the company in 2025. Most SAF today is made from waste oils and fats, and Singh says there is not nearly enough of either to meet demand.
Neela has received grants from Innovate UK and the Henry Royce Institute, and is part of airline group IAG's innovation programme.
Investors: Elbow Beach led the £2.1m (€2.4m) round, putting in £1.5m. Ascension, Cambridge Enterprise, Ventures Together and strategic angels also invested.
What the money is for: Neela will move from the lab to a pilot at a working biogas plant over the next two years.
Finches – €2m pre-seed
About: Finches makes AI software that warns food, drink, pharma and cosmetics companies about shortages of agricultural raw materials weeks or months ahead. It combines buyers' own procurement data with weather, satellite images, local news, research and agronomists' field reports.
It then suggests what to do, such as lining up backup suppliers, buying earlier or rescheduling production.
Catharina van Delden (CEO) and Dr Stefanie Glenn (CTO) founded the company near Munich in 2025. Alexandra Vázquez Bea joined as CFO, COO and co-founder in January 2026.
Finches says its early customers include an organic baby food maker and a North American Fortune 500 food group, which it did not name.
Investors: High-Tech Gründerfonds (HTGF) led the round, with Vanagon Ventures as co-lead. Bayern Kapital joined as a new investor, while UnternehmerTUM Funding for Innovators and a group of industry and tech angels followed on.
What the money is for: Finches will speed up product development and build out its sales team.
SensorX Solutions – €1.6m seed
About: Swiss startup SensorX makes laser-based sensors that find and measure methane leaks for gas utilities and grid operators. Its FluX platform can be carried on foot or fitted to vehicles, drones and fixed posts, and it handles the reporting.
Founder and CEO Sanket Bhatia started the company in 2023. SensorX says it has more than 15 customers and partners, including Swissgas, Transitgas and E.ON, plus its first clients in Canada and the US.
Investors: The CHF1.5m (€1.6m) round combines a loan guarantee from the Swiss Technology Fund, a federal climate policy instrument, with equity from private investors, including Swishfund, and the founders.
What the money is for: SensorX will scale up production, engineering and delivery. It will also research underwater leak detection and measurement of other greenhouse gases.
Elvy – €1.5m round extension
About: Stockholm-based Elvy installs solar panels, a heat pump and a battery in homes at no upfront cost, and keeps ownership of the equipment. Households pay a fixed monthly price for electricity and heating over 15 years.
Johan Outinen (CEO) and David Wedar founded the company in 2023. Elvy says 1,800 households have signed up, and that its systems cut their energy use by 60 per cent on average.
Investors: Leonardo DiCaprio joined the round through his family office, his first direct investment in a Swedish company, according to Outinen. Elvy would not disclose his stake, but Outinen told Impact Loop it is "a significant share".
The round extends Elvy's earlier raise of roughly €6m, led by US investors Daft Capital and Essential Capital.
What the money is for: Elvy did not say how it will use the new money. The company is growing installations under a credit facility of around €500m, which it says covers up to 15,000 households.
