Flexstone Partners (Flexstone), a global private markets investment manager with $12 billion in assets under management (AUM) and an affiliate of Natixis Investment Managers, has announced that it has reached an agreement to acquire Glouston Capital Partners (Glouston), a Boston-based private equity secondary markets manager with more than $3.4 billion in assets under management.
According to the firms, the combined platform will manage more than $15 billion in assets across primary, secondary and co-investment strategies, serving institutional investors across North America, Europe and Asia. The combined entity brings together two highly complementary businesses: Flexstone’s global primary and co-investment platform and Glouston’s North American secondary market capabilities, which operate largely in different geographies with minimal strategic overlap. Glouston’s experienced team, strong General Partner (GP) relationships and disciplined approach to the North American middle market will significantly strengthen Flexstone’s secondary platform and enhance its ability to meet the evolving needs of institutional investors.
“Flexstone Partners is delighted to welcome the experienced Glouston Capital Partners team as we embark on this new phase of growth. Glouston brings a complementary middle-market investment philosophy and a long track record of disciplined execution. Their expertise in the secondary market is a natural fit with our culture and broadens the range of private capital strategies Flexstone can offer investors through our platform,” said Eric Deram, Managing Partner and Chief Executive Officer of Flexstone Partners.
About the transaction
The investment and management teams at Flexstone will remain unchanged, ensuring continuity for clients while adding deep middle-market secondary expertise. Glouston’s investment strategy and investment team will also remain intact following the closing of the transaction. Glouston’s six partners will continue to manage the secondary business from Boston, applying the same investment process and criteria that have historically defined the firm’s investment approach.
“This partnership represents a natural evolution for Glouston Capital Partners. Flexstone’s global platform, complementary GP relationships and strong distribution network will allow us to expand our reach while maintaining the investment discipline and team-based decision-making that our Limited Partners (LPs) value. We are excited to join forces and continue building a leading secondary platform with the resources and scale needed to compete effectively in today’s market,” said Red Barrett, Senior Managing Partner at Glouston Capital Partners.
As part of the transaction, Glouston’s partners will reinvest a significant portion of their equity ownership in the combined entity and will become Managing Partners of Flexstone, ensuring strong alignment of interests. Flexstone’s partners will also make an additional capital investment alongside the Glouston team.
Expanding the private markets offering
According to Philippe Setbon, Chief Executive Officer of Natixis Investment Managers, investor demand for large-scale, high-quality private markets solutions continues to grow. “Private assets are a core pillar of Natixis Investment Managers’ long-term growth strategy, with Flexstone Partners playing a key role. Glouston Capital Partners’ experienced team, strong institutional relationships and differentiated middle-market strategy are an excellent complement to Flexstone’s private equity business. This integrated platform is uniquely positioned to meet clients’ evolving needs in one of the fastest-growing segments of private markets,” Setbon said.
The combined platform will operate from five offices—New York, Boston, Paris, Geneva and Singapore—and will include 37 investment professionals. Flexstone will continue to manage its primary and co-investment strategies across private equity, private debt, infrastructure and real estate, serving an institutional Limited Partner (LP) client base primarily located in Europe and Asia.
Glouston will lead the combined firm’s secondary investment strategy and U.S. distribution, while Flexstone’s secondary investment team—comprising three professionals in Europe and one in New York—will join forces with Glouston’s investment leadership team. Following the closing of the transaction, Glouston’s strategies will be marketed under the Flexstone Partners brand. The Glouston team will continue operating from Boston as part of Flexstone’s expanded global platform. Existing fund structures, LP agreements and investment mandates will remain unchanged following the rebranding.
