Nexus Luxembourg, the country's largest technology summit, returns to LuxExpo The Box on 10–11 June 2026 with more than 10,000 visitors, 150 speakers and a four-part programme spanning applied AI, fintech and a start-up contest — as Luxembourg positions itself as a European hub for trusted, sovereign computing.
Luxembourg's startup ecosystem counts more than 810 companies and raised €407 million in 2025. This guide maps the practical path for founders: setting up a SARL-S, getting the business permit, stacking equity-free grants such as Fit 4 Start (up to €150,000), raising from business angels and venture capital, and tapping the Luxembourg Future Fund, the European Investment Fund and EU money from the EIC.
Luxembourg's national innovation agency closed 2025 with its highest-ever support count and launched a redesigned, four-pillar service model. Minister Lex Delles and CEO Mario Grotz also confirmed the Luxembourg AI Factory, part of the EU's 19-strong AI Factory network, has assisted around 150 organisations since launch.
