Ireland Strategic Investment Fund (ISIF)

Invests in Irish strategic growth through public financing for projects that create jobs, innovation, and long-term competitiveness.

Ireland Strategic Investment Fund (ISIF) is Ireland's sovereign development fund, managed by the National Treasury Management Agency. It works on a commercial double-bottom-line model that aims to generate returns while supporting economic activity and employment in Ireland.

ISIF invests through equity, debt, and venture-capital commitments across climate action, housing, indigenous businesses, food and agriculture, quantum computing, advanced technology, and infrastructure. The listed route is ISIF Capital Investment, and the fund does not publish a fixed award cap because capital is deployed bilaterally. Governance sits with the NTMA Board, with an Investment Committee assisting on asset acquisition and strategy, and the public materials include impact reporting and exclusion lists for fossil fuels and cluster munitions.

That structure suits companies and projects that can absorb investment capital and clear commercial diligence. Recent commitments include a EUR 140 million climate-action fund in March 2026 and a EUR 75 million energy-grid support fund in January 2026, which shows how the fund pairs market discipline with strategic national priorities. Engagement is through direct contact and deal sourcing, not an open call.
