Ostrum Asset Management has created a new investment solutions team as part of a wider restructuring within its asset management division, appointing Iain Bremner as its inaugural director.

The move underscores Ostrum AM’s ambition to sharpen its focus on institutional client needs and enhance its tailored offering, the firm announced.

The investment solutions unit will be responsible for designing, coordinating and promoting bespoke strategies for institutional investors.

Bremner, who brings more than three decades of experience in institutional management, steps into the newly created role having served as chief operating officer of Ostrum AM’s asset management operations since 2020.

He began his career at CEPME (Bpifrance) and held senior fixed income roles at Sogeposte and AGF AM. At La Banque Postale AM, he led the rate and credit asset management and research division, where he played a key role in its full transition to socially responsible investment and the implementation of MiFID II.

Bremner officially took on the position in January 2025 and reports to Gaëlle Malléjac, Ostrum AM’s global CIO, who was appointed to her new role last October.

The announcement is part of Ostrum AM’s wider organisational alignment following the consolidation of all asset management and research functions under Malléjac’s leadership.

As part of the reshuffle, Xavier-André Audoli has been named chief investment officer for insurance and institutional asset management. A long-serving figure at the firm, he will continue to oversee the multi-asset insurance and institutional management team, which he has led since 2019.

Meanwhile, Stéphanie Noël has been promoted to head of the systematic asset management team within the quantitative investments and research division. Her remit includes driving alpha generation across Ostrum AM’s strategies, drawing on her deep experience in systematic and structured investment approaches.

Ostrum AM, an affiliate of Natixis Investment Managers, has positioned the appointments as a key step in enhancing its service quality and competitiveness in the institutional market, it said.

“These appointments reflect our dedication to strengthening our expertise to drive the performance of our investment strategies. Xavier-André, Iain, and Stéphanie each bring valuable experience and insights that will enhance Ostrum Asset Management’s standing among the leading players in the market. Together, we remain committed to innovation and to providing investment solutions that meet the evolving needs of our institutional clients,” said Malléjac.
