What Duke Street does
Duke Street is a London-headquartered private equity firm founded in 1994 that invests in mature, mid-market Western European businesses, typically at enterprise values between €50m and €350m. The firm concentrates its investments across four core sectors — Consumer, Healthcare, Industrials & Engineering, and Services — and has deployed over €3bn into more than 50 companies over its 25+ year history, reporting returns in excess of 25% IRR through the cycle. Its investment model emphasizes proprietary origination on an exclusive basis, deliberately avoiding competitive auction processes, and pursues value creation through operational transformation, organic growth, and buy-and-build strategies supported by a bench of Operating Partners.
The firm's funding model has evolved from Fund VI (established 2006) to a deal-by-deal club structure (from around 2012) and, since 2017, to a hybrid Cornerstone Fund anchored by Goldman Sachs Asset Management (providing up to 50% of equity per deal) alongside Arcano, complemented by a global LP base spanning Fund of Funds (41%), Financial Institutions (29%), Pension Funds (18%), and Family Offices (12%). Duke Street itself co-invests substantially in each transaction to align interests with management teams and LPs. Notable current and recent platforms include McAvoy (modular buildings), Suir Engineering (mechanical/electrical engineering), COMPO (gardening products), Kent Pharma (generic pharmaceuticals), AGITO Medical (medical imaging), ForLife/Unora (ostomy care), A-ROSA (river cruises), TeamSport (indoor karting), and Ardent Hire Solutions (plant hire).
Duke Street generates revenue from three primary streams: management fees on funds under management (recurring), carried interest crystallized on successful exits (transaction-based), and returns from deal-by-deal co-investments alongside its LP club. The firm is privately held with no parent company, and Tikehau Capital acquired a 30% stake in 2013. Notable exits include Wagamama (£559m EV, 3.4x MOIC, 2018), Baywater Healthcare (5x+ cost, 2018), Medi-Globe (€245m EV, 2022), Voyage Care (2022), and Great Rail Journeys (2025).
