The company, founded in 2020 in Moldova, aims to address pollution of transport infrastructure and limited access to aquatic resources. They plan to launch a car wash service using clean technologies and a circular water usage concept. The innovation includes efficient water and energy usage through the integration of solar panels. With a maximum timeline of 6 months, the main obstacle is potential equipment import delays. The leadership team, Natalia Dorofeev and Tatiana Dragan, lack previous management experience but hope to gain knowledge through the GCIP Accelerator program. They expect their technology to have a positive environmental impact and become a leading car wash service provider in Moldova.

MELT WATER has developed the world's first freeze-based (cryogenic) water purification technology: only pure water crystallizes into ice while contaminants remain liquid and drain away, so no filters or membranes are needed and natural minerals are preserved. Its AI-integrated, maintenance-free smart device delivers cold, hot, sparkling water, and ice in one unit, with a mobile app for real-time monitoring and sustainability reporting. Compared with conventional filters and reverse osmosis, MELT eliminates consumables and plastic waste and cuts wastewater by up to seven times. The company sells directly and via subscription across home, plus, and pro product lines for households, offices, and hospitality. Its environmental impact is substantial: every 1,000 devices save around 15,000 kg of plastic and 24 million liters of water each year. MELT has deployed over 200 devices, built a partner network through its bottled-water arm, and earned recognition including Top 100 Ukrainian startups and a Forbes foodtech listing. The company's founder, Andrew Osadchyi, also served as a juror at Cleantech Days 2026.

SpaceLab develops satellite-connected IoT systems and industrial sensors, enabling real-time monitoring, disaster prevention, and ecological protection across remote, hazardous, and underserved environments worldwide

Geodesic.Life produces prefabricated, eco-friendly geodesic dome houses that function as healthy, low-carbon homes and let people live sustainably in connection with nature. Its Gen.3 dome uses an optimised envelope that cuts energy and material use by around a third, with 95% recyclable hemp-lime insulation and up-cyclable cross-laminated timber. A patent-pending Quick Assembly Technology enables all-wood, click-together assembly using a mini-crane and an inflatable tent for weather-independent construction, complemented by a BIM SaaS platform that spans design, manufacturing, and assembly. The business model combines dome design, prefabricated kits, and the software platform, selling to real-estate and hospitality partners and to rural communities. Impact is central: roughly a 71% lower CO2 footprint and about 73% of materials up-cycled versus standard construction. Geodesic.Life has two inhabited prototype generations and EU validation through the New European Bauhaus. Geodesic.Life was named a Top 3 Finalist in the global Growth Track competition at Cleantech Days 2026.

CTSolutions reliably separates feedstocks into commercial oil of the 1st quality category, purified water, and solid phase waste. The solution is a universal technology for the step-by-step separation of feedstocks on centrifugal equipment. It allows the processing of all types of oil-containing waste. Deep processing of oil into a commercial form by more than 98% ensures rational and efficient use of the available feedstock. It is a high-tech solution to economic and environmental problems.

CTSolutions has already been put into industrial operation. Significantly, they've processed an industrial volume of 5000 m3 that could not be processed by any other economically and technologically acceptable method. They've achieved a record return of feedstock to commercial form of more than 98% of the potential. The solution can be used to process all types of oil-containing waste.

Having received patents for the method of processing oil-containing waste, CTSolutions has the necessary competencies to implement the large-scale task of processing technogenic waste.
