Startup Luxembourg ecosystem report - Facts & Figures
Luxembourg has positioned itself as a vibrant startup hub, offering a highly supportive business landscape and international ties. This report provides key insights into the country’s startup and scaleup ecosystem as of the end of 2025.
Luxembourg’s startups and scaleups ecosystem at a glance
Luxembourg has rapidly emerged as a dynamic hub for startups, combining a supportive business environment with strong international connections. The government has complemented its “From Seed to Scale” roadmap with a bold 10-point action plan to strengthen financing, create sector-specific incubators, expand internationalisation programmes and launch new measures to attract talent and incentivise private investment.
In this report, we explore the national startup and scaleup ecosystem. The information stems from an analysis conducted based on the Dealroom dataset of startups and scaleups active in Luxembourg and founded since 2005 (until 2025).
The startups and scaleups listed on the Dealroom database align with the following criteria: rapidly scaling/scalable entities, maximum 20 years old, innovative by design and active in Luxembourg (headquarters, founding place or a regular office).
Our analysis shows an established and increasingly structured ecosystem, now comprising more than 810 startups and scaleups. Over the past few years, the ecosystem has diversified significantly, with new companies emerging across sectors such as space technologies, healthtech, energy, cleantech and cybersecurity. AI adoption has accelerated markedly, with over 240 startups now leveraging AI technologies, doubling the size of the AI-driven ecosystem since 2020. Funding dynamics indicate robust early-stage support, while progressively strengthening pathways for scaling companies.
To ensure comprehensive coverage, startups not yet listed on Dealroom are invited to create a profile and contribute to future ecosystem analyses (link to connect: Dashboard | Luxembourg Startup Ecosystem).
