The Private Shares Fund is a U.S.-focused venture/private-market interval fund that invests in shares of private technology companies, primarily late-stage companies with some seed-round participation. It targets sectors including space and aerospace, AI and machine learning, defense, enterprise software, fintech, cybersecurity, logistics, payments, supply chain, B2B marketplaces, robotics, automation and SaaS. The fund is most relevant for venture-backed U.S. companies seeking capital from an investor focused on less liquid private-market opportunities.
