The European Investment Bank is the lending arm of the European Union and one of the world's largest multilateral development banks. It provides loans, guarantees, and equity-like instruments to companies and projects across EU member states and partner countries. The EIB has an active healthcare and life sciences portfolio and provides substantial debt and quasi-equity financing to medtech, biotech, and digital health companies.

For neurotech companies in Europe, the EIB is particularly relevant as a non-dilutive debt funder or as a component of blended finance structures alongside venture capital. The EIB frequently co-finances alongside EIC grants and private investors, making it a key enabling partner for European neurotech scale-ups.
