Summary
Flexstone Partners, a global private markets manager overseeing approximately $12 billion in assets under management and majority-owned by Natixis Investment Managers, has agreed to acquire Glouston Capital Partners, a Boston-headquartered private equity secondaries specialist managing more than $3.4 billion in committed capital. The transaction will create a combined platform with more than $15 billion in total assets under management, representing substantial growth in Flexstone's institutional investment capabilities.
The acquisition strategically combines two complementary businesses with limited geographic and strategic overlap. Flexstone brings a global primary and co-investment platform to the transaction, while Glouston contributes a well-established North American secondaries business with deep expertise in middle-market private equity investments. This structure allows the combined entity to offer institutional investors across North America, Europe, and Asia a broader range of private equity solutions spanning primary fund investments, direct co-investments, and secondaries strategies—a portfolio that neither firm could offer as effectively independently.
Eric Deram, Managing Partner and CEO of Flexstone Partners, stated that "Glouston's team brings a complementary investment philosophy to the middle-market landscape and a long history of disciplined execution," emphasizing that the secondaries expertise aligns with Flexstone's culture and operational approach. Glouston Capital Partners, founded in 1994 and structured as a 100% employee-owned firm, brings over 30 years of dedicated experience in private equity investing and a track record of disciplined execution in secondary investments.
Both firms have committed to continuity for existing clients and stakeholders. Flexstone's investment and management teams will remain unchanged, ensuring consistency in existing relationships and operations. Critically, Glouston's investment strategy, team composition, and Boston-based operations will continue without disruption following the transaction's close. The six Glouston partners will join Flexstone as Managing Partners and will maintain responsibility for overseeing the secondary investment business using the same investment processes and criteria that have defined the firm's historical performance.
This acquisition reflects broader consolidation trends in the alternative asset management sector, where mid-sized specialists with complementary capabilities are combining to achieve greater scale and product breadth while preserving operational independence and investment discipline.
