Olga Kosters has been named managing director and head of credit secondaries at alternative credit manager Antares Capital, said a news release Jan. 29.
The position is new, a spokesperson confirmed.
Kosters will help oversee the expansion of Antares’ credit secondaries investment strategy, “which will focus on both GP (general partner)-led and LP (limited partner)-led credit secondaries opportunities leveraging the firm’s extensive private credit and structuring expertise,” the news release said.
Based in New York, Kosters reports to Benjamin Chapin, managing director and head of liquidity solutions.
In 2025, Antares plans to increase its activity in the credit secondaries market and continue building its dedicated credit secondaries team, the release said.
Kosters previously was a managing director, co-managing credit secondaries at Apollo Global Management. A source familiar with Apollo said Kosters looked after credit secondaries day-to-day alongside Michael Maechling, managing director-credit, who joined Apollo in February 2024. Maechling will continue to run this business and report to Steve Lessar, Veena Isaac and Konnin Tam, all of whom are partners and co-heads of Apollo's sponsor and secondary solutions business.
According to her LinkedIn page, Kosters left Apollo in October.
Bloomberg reported Oct. 15 that Kosters left Apollo to “start a new fund focused on trading private credit stakes.”
Antares Capital had about $80 billion of capital under management and administration as of Dec. 31.
