Five new European startups to know (early October 2026)
Health checks in Amsterdam, smarter solar and batteries in Belgium, home care in France, WhatsApp doctors in Portugal and hydrogen from ammonia in Spain: five young companies with fresh funding.
Five young European startups announced new funding in the last weeks of September 2026: Blue Health Intelligence (Netherlands), CIOC Energy (Belgium), Relaisanté (France), Usawa Care (Portugal) and H2SITE (Spain). None of them is an AI company first. They work on health, energy and care, the everyday things people and businesses actually pay for. Here is what each one does and what is new, based on public announcements.
Blue Health Intelligence: a full health check for 299 euro
Blue Health Intelligence, from Amsterdam, offers preventive health checks for 299 euro. Its 360-degree check looks at heart health, metabolism and liver and kidney function, and a doctor goes through the results with you right after the test. The company was founded in 2025 by Onno Huyghe, formerly of Swapfiets and Tibber, and physician Leanne Verdonck. It says more than 2,000 people have booked a check since launch. On 30 September 2026 it announced a 3.4 million euro round led by Knop Investments, and it plans to open in Paris or Milan in the first half of 2027. Website: bluehealth.co. Source: EU-Startups.
CIOC Energy: keeping solar panels and batteries working
CIOC Energy, from Belgium, runs a platform to monitor, control and trade energy from solar panels and batteries. Founded in September 2023 and led by CEO Alexander De Bièvre, it manages more than 100 business sites directly and about 2,000 home batteries through its partner CleverNett. In total it manages over 200 megawatt-peak of solar and more than 100 megawatt-hours of battery capacity. On 23 September 2026 CleverNett took a minority stake for 3 million euro. CIOC wants to use the money to grow its team and get direct energy market access in Belgium, the Netherlands, Germany and Romania. Website: cioc-energy.com. Source: Tech.eu.

Usawa Care: a doctor on WhatsApp
Usawa Care, from Portugal, lets families talk to licensed doctors through WhatsApp, starting with children's health for 12 euro a month per family, with a free version that has shorter hours and longer waits. CEO Luís Almeida Fernandes previously ran Portugal's national health line SNS24. The service has more than 12,000 registered children and handles about 1,000 consultations a month. On 24 September 2026 it announced a 3 million dollar seed round led by Armilar, and an adult service for 7 euro a month launches on 12 October 2026. Website: usawacare.com.

H2SITE: hydrogen power from ammonia
H2SITE, from Loiu near Bilbao in Spain, builds membrane reactors that produce and separate hydrogen, including from ammonia, so hydrogen can be made close to where it is used. Led by CEO Andrés Galnares, it received 3.4 million euro from Enova, reported on 22 September 2026, to develop HydraNord Power, a project that scales its ammonia-to-power system for ships.
