Hg committed $500 million to Rightsline, a provider of rights and royalties management software for IP-intensive industries. Co-investors Klass Capital and Salem Partners will join alongside the existing management team. The deal targets accelerating Rightsline's product and AI roadmap as demand for IP management tools grows across creative and technology sectors.

Rightsline operates in a specialized niche, serving companies that need granular tracking of intellectual property rights and royalty distributions. The size of the investment signals Hg's conviction that software-based IP management is a high-margin, recurring-revenue opportunity. Having Klass Capital and Salem Partners invest alongside current management suggests alignment on long-term commercial strategy.

Rightsline has already launched a suite of AI-powered products, placing the company at the intersection of IP management and artificial intelligence. For Hg, the deal extends its portfolio into enterprise IP infrastructure where demand is rising and margins are attractive.
