Rightsline, a leading provider of rights and royalties management software for IP-intensive industries, today announced a $500 million strategic growth investment from Hg, a leading investor in transatlantic technology businesses.
Klass Capital, Rightsline’s majority owner since 2020, Salem Partners, and the broader management team will invest meaningfully alongside Hg, reflecting their continued confidence in the business.
The global proliferation of streaming platforms, cross-border content licensing, and IP-intensive business models has created a growing operational challenge for rights holders, who need to track who owns what, where, and ensure the right parties get paid. Rightsline provides the software that major studios, publishers, consumer brands, and life sciences firms use to manage that complexity at scale.
Originally established as a leader in media and entertainment rights management, Rightsline now operates across eight IP-intensive verticals and serves more than 300 of the largest organisations worldwide, across media and entertainment, publishing, consumer products, life sciences, technology, gaming, music and franchising. The company offers a truly unified rights and royalties platform, with a single system spanning rights management, royalty calculation, financials, and accounting, delivering audit-grade outputs. The platform processes more than $40 billion of royalties annually and manages over 150 million IP assets across 28 countries.
Accelerating momentum
2025 was a year of record growth for Rightsline across bookings, revenue and retention, reflecting the mission-critical role the platform plays in its customers’ day-to-day operations. This momentum continued into 2026 with another record quarter in Q1.
The company has already launched a suite of AI-powered products for its customers, including an AI contract ingestion assistant that automates extraction of key terms from complex legal agreements, and a natural-language rights and availabilities assistant that enables users to interrogate their rights libraries in plain English.
Hg’s investment will accelerate Rightsline’s product and AI roadmap and support the company’s international expansion, drawing on Hg’s transatlantic network and its team of more than 100 AI specialists. This includes Hg Catalyst, its dedicated AI product incubator, which has supported the launch of more than 30 AI products across its portfolio to date.
Patrick Arkeveld, CEO of Rightsline, said: “The IP landscape has become increasingly complex, with more platforms, territories, and contractual complexity than ever. That creates a clear opportunity for us to innovate on behalf of our customers and make their lives meaningfully easier, but more crucially to drive better business outcomes. Farouk and the Hg team are the ideal partner to help us deliver on that ambition, combining deep AI and operational expertise to accelerate our product roadmap and a transatlantic network to support our expansion into new geographies and verticals. We’re also grateful for the continued support of Daniel and Klass Capital, whose reinvestment reflects the shared conviction we all have in what lies ahead.”
Farouk Hussein, Partner at Hg, said: “Patrick, Daniel, and the Rightsline team have built something genuinely exceptional. Rightsline provides a truly unified rights and royalties platform, bolstered by proprietary calculation engines, data, and algorithms, enriched with decades of domain experience. The company boasts an impressive roster of blue-chip customers and a consistent track record of sustained growth and retention that speaks to how deeply embedded the product is in its customers’ legal, sales, finance and operations workflows. Rightsline is incredibly well-positioned to expands its presence across its core verticals with this growth investment, and we’re excited to work hand-in-hand with management and our Hg Catalyst team to build the next generation of agentic AI products for IP lifecycle management.”
Daniel Klass, Founder of Klass Capital, said: “Patrick and the team have built Rightsline into a clear global leader in rights and royalties software. When we set out to find our next partner, we wanted a firm that shares our growth ambitions and has the operational depth – particularly in AI and international scaling – to help take the company to the next level. Hg was the clear choice, and our decision to reinvest meaningfully alongside them reflects our strong conviction that the best chapter for Rightsline is still ahead.”
Donna Laing, Vice President, Royalty Accounting & Rights Data Management, Scholastic, said: “In publishing, royalties vary by channel, format, territory and more, and simply knowing what we have the right to sell in each market can be incredibly complex. Keeping track of all that, and making sure the right people get paid accurately, is a real operational challenge. Rightsline handles that complexity for us and, as the publishing world continues to grow more complex, we’re excited to see Hg’s investment accelerate what’s already an industry-leading platform.”
As part of the investment, Farouk Hussein and Annie Wei from Hg will join the Rightsline board alongside Daniel Klass and Patrick Arkeveld. Ron Kasner will join as independent Chair given his multi-decade experience in scaling technology companies.
AQ Technology Partners, Brown Rudnick and Goodmans served as exclusive financial and legal / tax advisors to Rightsline. RBC, Latham & Watkins, and PwC served as exclusive financial, legal and integrated diligence advisors to Hg.
