The transaction materially expands Flexstone's capabilities in the secondary market and increases the combined firm's assets under management to more than $15 billion across primary, co-investment, and secondary private equity strategies.
The acquisition strengthens Flexstone's competitive positioning in the North American middle-market secondaries segment while integrating Glouston's established network of relationships within the private equity industry. The enlarged platform will serve institutional investors across North America, Europe, and Asia, broadening geographic reach and investor base.
Glouston's entire investment team has joined Flexstone and will continue operating from its Boston office. Critically, the transaction preserves operational continuity: existing fund structures, limited partner agreements, and investment mandates remain unchanged, and Glouston's strategies will be rebranded under the Flexstone Partners name rather than restructured. Glouston's six investment partners have been elevated to Managing Partner positions within Flexstone, ensuring alignment and retention of key talent across the combined business.
The enlarged Flexstone platform now comprises 37 professionals distributed across five global offices in New York, Boston, Paris, Geneva, and Singapore. Glouston brings substantial pedigree to the combination, having specialized in North American buyout middle-market secondaries since its founding in 1994, with more than $2.9 billion invested across 290 secondary transactions on behalf of institutional investors. This transaction positions Flexstone as a more comprehensive private markets platform with enhanced depth in the secondaries market segment.
