What is ESA?

ESA (European Space Agency) is an intergovernmental organisation of 23 member states, founded in 1975 and headquartered in Paris, that develops Europe's space capability — launchers, science missions, Earth observation, telecommunications and navigation. For space startups it is one of the two big European funding pillars (the other being the EU), issuing thousands of competitive tenders and running incubation and co-funding programmes.

How ESA funding works

ESA runs mandatory activities (science, basic budget — every member contributes by GDP) and optional programmes (telecom, exploration, Earth observation…) where each country chooses how much to subscribe. Money broadly flows back to national industry via the geographical return principle — meaning your eligibility for many ESA tenders depends on your country's subscriptions, not just your tech.

Startup-relevant entry points:

Open invitations to tender are published on ESA's esa-star portal — VIRA tracks them alongside EU calls in one place: see live tenders.

ESA vs the EU space landscape

ESA is often confused with the EU's space bodies. In short: ESA builds and procures; the EU Space Programme (Galileo, Copernicus, IRIS²) is EU-funded infrastructure, with EUSPA running services and market uptake. Many missions are joint.
