Vækstfonden is a Danish state investment fund that promotes growth and innovation in entrepreneurial firms and SMEs. It provides equity, loan capital, and guarantees to support growth loans, growth guarantees, and "get started" loans. Over time it has increased its direct and indirect investments in companies and guarantees provided. It aims to leverage its funds to attract greater private investment. Key lessons learned include the need for ambition and specialization to achieve solid long-term investment returns, selecting the right investment professionals, and using smart subsidies like loans rather than direct equity to support companies while maintaining good governance.
