SeaO2 develops Direct Ocean Capture (DOC) technology that extracts CO2 from seawater and returns carbon-free water to the ocean, enhancing the ocean's ability to absorb atmospheric CO2. The company plans to scale from prototype to a pilot plant with an expected annual capacity of 250 tons of CO2, scheduled for launch in summer 2025. SeaO2 intends to use recent funding to accelerate technology development, expand the team, and implement a comprehensive Monitoring, Reporting, and Verification (MRV) system. It has set removal targets of one megaton of CO2 by 2030 and one gigaton by 2045. The company has established strategic partnerships with XPRIZE Carbon Removal, TU Delft, Klarna, Wetsus, and Redstack and participated in a carbon removal project with Paebbl in the Wadden Sea. Financially, SeaO2 raised over €2m in the reported funding round to support these plans. SeaO₂ is an Amsterdam-headquartered startup (founded in 2021) building ocean-based CO₂ removal systems that lower seawater pH with electrodes across a membrane to liberate gaseous CO₂. The process treats water offshore, releases CO₂ which is captured, and then returns decarbonized water to the surface to re-equilibrate. Captured CO₂ is intended for permanent underground storage. The company operates a prototype in the North Sea launching from the REDstack renewable energy plant at the Afsluitdijk dam and plans a larger pilot by the end of 2023. The initial prototype can extract about one ton of carbon per year; the next pilot is slated to extract 250 tons per year. SeaO₂’s stated ambition is to remove 1 gigaton of carbon by 2035. Ledgy has partnered with and made an early commercial pre-purchase to help validate SeaO₂’s commercial model and support its R&D.

Nuventura develops SF6-free medium-voltage (MV) gas-insulated switchgear using a patented technology that replaces sulphur hexafluoride (SF6) with dry air. Its hardware is used throughout electrical grids and energy infrastructure, and the company works with OEMs, EPC providers, and project developers. Nuventura shares its technology through a partnership model to divide the value chain and accelerate adoption. The company positions its product to help customers comply with imminent international regulation on SF6 and to extend product portfolios into new market segments. Nuventura recently closed a €25M Series A, bringing total funding to €35M. The company plans to use the proceeds to expand its product portfolio and further develop manufacturing capabilities around the world; it is led by CEO Dr. Fabian Lemke. Nuventura is a Berlin-based developer of medium-voltage (MV) gas-insulated switchgear (GIS) that replaces sulfur hexafluoride (SF6) with dry air using a patented technology. Rather than manufacturing finished switchgear, nuventura sells key components or licenses its full technology to established switchgear manufacturers. This business model is designed to be highly scalable and lets customers adopt SF6-free GIS while avoiding large R&D costs. Nuventura says its technology could help tackle annual SF6 emissions equivalent to the yearly CO2 emissions of roughly 100 million cars. The company is pursuing industrialization and expansion into Asian markets, and has secured support from ADB Ventures to aid those efforts. Nuventura positions itself to enable a more sustainable electrical grid by accelerating adoption of SF6-free solutions.

Fairphone builds modular, repairable smartphones and has expanded into related hardware like earbuds that use recycled plastics and Fairtrade gold. The company emphasizes circular-economy principles and aims to lengthen device longevity through repairable-by-design hardware and extended software support. Fairphone plans to accelerate integration of fair and recycled materials across its product portfolio and expand mining value-chain programs in Africa and South America, alongside fair wage programs in Asia. It is investing in product development, improved customer service and brand positioning to raise awareness around fairness and sustainability in electronics. The company has shown unit growth, selling around 120,000 devices last year, up from about 88,000 in 2021 and 23,000 in 2018. Fairphone presents itself as a mission-driven business positioned to benefit from EU pushes for circular models and right-to-repair policies. Fairphone, founded in 2013 in Amsterdam, is a social enterprise building "ethical electronics" and manufactures the repairable Fairphone 2. The Fairphone 2 runs Android, retails for €399, and is notable for high repairability; the company sells modules (battery, camera, display, speakers) on its website. Fairphone prioritizes ethics across the supply chain, from mining to manufacturing to the device's lifecycle. In recent months it raised €20 million across equity crowdfunding, a social-impact funding round, and debt financing. The company said it will use the funding to sustainably scale operations, research new products and business models, and expand sales efforts in untapped European markets. Fairphone also appointed Eva Gouwens as CEO; founder Bas van Abel will remain involved as a member of the supervisory board. Fairphone is a Dutch startup founded in 2010 that builds smartphones designed for ethical sourcing, repairability, durability, and transparency. The company sources minerals—mostly from Congo—from mines outside conflict zones and assembles phones in China while aiming to ensure fair wages for workers. Its products emphasize long shelf life to reduce e-waste, and for each phone sold Fairphone directs €3 to a service organization involved in recycling electronic waste in developing countries. The company produces relatively small volumes rather than mass-market device quantities. Financially, Fairphone recently raised about €2.5M via a crowdfunding convertible loan and previously attracted €6.5M from impact investors in 2017. The company plans to use the crowdfunding proceeds to launch a new phone and expand its presence in Southern Europe and the Scandinavian countries. Fairphone designs modular, repairable smartphones with the stated aim of supporting longevity and sustainability across the electronics value chain. Its core product emphasizes repair-by-design, though the company recently ended support for its first handset after suppliers retired spare parts and chipset makers stopped issuing updates. Fairphone used crowdfunding to build that first device and says it has sold more than 135,000 smartphones over four years. The company plans to scale its approach to create a circular economy for consumer electronics, targeting material sourcing, production, distribution and recycling. It intends to bring suppliers and consumers along to build a viable market for fairer electronics and to negotiate longer component availability, Fairtrade gold sourcing and better working conditions. Fairphone has also appointed Eva Gouwens as managing director to grow the organization and its value-chain impact. Fairphone is an Amsterdam-based social enterprise aiming to produce the most ethical smartphone, with a focus on longevity and repairability. Its flagship device in this campaign was the Fairphone 2, offered via pre-order at an average price of €525 (VAT included). In two months close to 17,500 pre-orders generated roughly €9 million. Those funds will kick-start production and allow the organisation to continue investing in social impact projects. Fairphone published a cost breakdown to show buyers what their payments support. Founder and CEO Bas van Abel has discussed the company’s model and ambitions in interviews.
