Circular Venture Programme

Circular New Venture Programme 

Ireland’s first accelerator dedicated to circular ventures

CIRCULÉIRE’s Circular Venture Programme is the first of its kind in Ireland targeting circular ventures seeking to scale and is delivered in collaboration between Irish Manufacturing Research (IMR) and Tangent, Trinity’s Idea Workspace.

Our Circular Venture programme is a combination of non-equity funding and mentoring that supports circular entrepreneurs who are demonstrating or enabling circular models to impact Ireland’s consumer behaviour, the economy, and accelerate the national transition to a circular economy.

Through the programme, CIRCULÉIRE helps entrepreneurs to impact Ireland’s consumer behaviour, the economy, and accelerate the national transition to a net-zero carbon circular economy.
