Big ideas from a small nation: 10 of the most promising Luxembourg startups to watch in 2026
Following up on our country deep-dive series, we now turn to Luxembourg, a small but strategically positioned ecosystem that continues to punch above its weight in European innovation. Known for its strength in finance, space, and cross-border industry, the country has steadily expanded into healthtech, climate tech, robotics, and digital infrastructure.
While Luxembourg’s startup scene may be more compact than larger European hubs, it benefits from strong institutional backing, international talent, and close proximity to major EU markets. The ecosystem increasingly reflects a blend of regulated-industry expertise and deep technical ambition, with companies building in areas such as FundTech, biotech, industrial automation, and circular economy technologies.
In this article, we highlight 10 of the most promising Luxembourg-based startups founded from 2021 onwards. Presented in alphabetical order, the selection focuses on companies that have secured funding, developed defined products, and are positioning themselves for continued growth into 2026 and beyond.

Its software supports prevention and surgical planning by enabling surgeons and medical device companies to test different scenarios in a virtual environment before intervention. By modelling spine biomechanics digitally, MDsim aims to improve decision-making, reduce complications, and support more personalised care pathways. With its latest funding round reported in 2025, they have raised a total of €2.3 million.
Founded in 2021, R3 Robotics develops automated robotic systems for the industrial dismantling of electric vehicle components. The company focuses on end-of-life processing of complex systems such as battery packs, e-drives, and power electronics, aiming to replace manual disassembly with scalable, repeatable automation.
Its platform combines robotics, adaptive motion planning, and specialised tooling to safely dismantle high-voltage components at an industrial scale. R3 offers both Disassembly-as-a-Service and Robotics-as-a-Service models, supporting recycling, reuse, and material recovery operations. The company has raised €28.5 million, with its latest funding round completed in 2026.
Founded in 2025, S.P.O.N.S.O.R. (SCOP) is an AI-powered climate fintech platform focused on scaling climate mitigation project finance.
