What Stirling Square Capital Partners does
Stirling Square Capital Partners is a London-headquartered, pan-European mid-market private equity firm founded in 2002, managing approximately EUR 3.5 billion in assets under management across multiple flagship funds, the latest being a EUR 720 million fifth fund closed in March 2026. The firm invests in companies with enterprise values between EUR 100 million and EUR 500 million, pursuing a thematic strategy centered on the internationalization and digitalization of mid-market European businesses, with execution primarily through platform investments supplemented by extensive bolt-on activity. To date the firm has backed more than 30 platform companies and completed over 100 add-on acquisitions, building positions in sectors including information services (Byggfakta/Hubexo, Infobric), industrial specialty chemicals and recycling (Itelyum), luxury packaging (Verescence, Tapì), and data/AI services (Iconsulting).
The firm operates a traditional private equity business model, generating revenue through management fees on committed or invested capital across its funds, supplemented by carried interest on realizations and ancillary fees (monitoring, transaction, director fees) from its portfolio companies. Its value-creation approach combines operational improvement, cross-border expansion into adjacent European markets, and targeted digitalization — supported internally by a Data Science function (headed by Ahmed Khamassi) and a recently acquired data and AI services platform in Iconsulting. Leadership is composed of Managing Partner Henrik Lif alongside Executive Chairmen and co-founders Stefano Bonfiglio and Gregorio Napoleone, with the partner group committing 16 percent of fund equity, providing material alignment with limited partners.
The firm maintains offices in London (headquarters) and St Helier, Jersey, reflecting its European investment footprint and fund-domicile structure. Its recent activity — including the EUR 720m fund close, the November 2025 Iconsulting acquisition, the May 2025 Verescence exit, and the May 2024 Byggfakta take-private — illustrates a continuing cycle of capital deployment, operational value creation, and realization across European mid-market platforms.
