Longwall Ventures

Longwall Ventures is a UK venture capital firm specialising in deep technology, providing early venture capital and company-building support since 2008. It focuses on turning university and lab-based research into commercial businesses, working across areas such as advanced manufacturing, life sciences, defence and clean energy. The firm describes itself as taking a patient, hands-on approach, working closely with founders from an early stage, avoiding over-engineering and building relationships with customers before pushing products to market. Its portfolio has included Oxford Space Systems, which designs satellite antennas using textile-knitting and origami-inspired techniques; Caristo Diagnostics, which analyses CT angiogram scans to assess coronary inflammation and heart attack risk; OrganOx, whose machine perfusion platform extends the preservation time of organs for transplant and is used as standard of care in a number of US transplant centres; and Wayland Additive, a metal additive manufacturing company.
