European Space Agency (ESA) is set to host its prestigious Industry Space Days (ISD) event on September 16-17, 2026, at ESA-ESTEC in the Netherlands. This pivotal gathering will convene Europe’s burgeoning space industry, fostering an environment for idea exchange, capability showcasing, collaborative discussions, and the exploration of new opportunities with ESA. A significant focus of this year’s event will be on empowering innovative startup companies, particularly those emerging from ESA’s extensive network of Business Incubation Centres (BICs).
The ISD serves as a crucial platform for the entire European space sector, from established industry giants to nascent enterprises. The event aims to accelerate the commercialization of space technologies and services by facilitating direct interactions between stakeholders. In an era of rapid technological advancement and increasing private investment in space, the ISD 2026 is anticipated to be a catalyst for significant collaborations and the advancement of Europe’s competitive edge in the global space market.
ESA’s commitment to nurturing space innovation is underscored by its network of 40 Business Incubation Centres (BICs) strategically located across 23 European Participating States. These BICs are instrumental in providing comprehensive business support to over 250 new space-based start-up companies annually. This support extends beyond mere incubation, offering access to technical expertise, market intelligence, and crucial networking opportunities. The Industry Space Days are a prime example of how ESA translates this incubation effort into tangible market engagement for its supported ventures.
A dedicated "ESA BIC Village" within the ISD Exhibition Hall will host 32 selected startups. These companies, chosen for their groundbreaking ideas and potential to leverage space for innovative applications, will each share a booth for one day, presenting their products, services, and unique innovations to a targeted audience of potential customers, investors, and business partners. This concentrated presentation format is designed to maximize exposure and facilitate meaningful connections within the limited timeframe of the event.
"At Industry Space Days, there will be thousands of pre-planned business meetings, presentations from ESA directors and industry leaders, and forums to share ideas and collaborate on new commercial uses of space," stated Jens Kauffmann, Head of ESA’s SME Section, the organizing body for the event. "This is an unparalleled opportunity for startups to introduce themselves to other industry players of all sizes for potential collaboration. It’s about building the future of the European space economy, together."
The startups featured in the ESA BIC Village represent a diverse spectrum of cutting-edge technologies and services, spanning both upstream (satellite design, launch, operations) and downstream (satellite data applications, services) markets, as well as technology transfer initiatives. The comprehensive exhibition hall at ISD 2026 will list all companies with a booth, providing attendees with a detailed overview of the innovative landscape present at the event.
