What Keyhaven Capital Partners does

Keyhaven Capital Partners Ltd is an independent, owner-managed private equity firm headquartered in London, founded in 2003, specialising in the European lower mid-market. The firm invests in companies with enterprise values typically below €250 million, either alongside best-in-class local sponsors (Ama Capital, Augens Capital, Miura, Sullivan Street, Duke Street, Chiltern, Alantra, Adelis, capital D, TriSpan, Magnum) or on a direct basis, focusing on B2B business services, healthcare, and manufacturing. Since inception, Keyhaven has invested or advised on more than €2.3 billion of capital across over 70 transactions spanning the UK, Spain, Italy, Germany, France, the Nordics, Benelux, and Ireland, with portfolio company operations extending into the US, China, Malaysia, Thailand, and Croatia. Deal flow is generated through a proprietary in-house sourcing programme built on bottom-up market mapping that deliberately avoids intermediated auction processes, enabling purchase prices and leverage levels approximately half the market average.
