Antares Capital, an alternative credit manager with approximately $80 billion in capital under management and administration, announced the appointment of Olga Kosters as Managing Director, Head of Credit Secondaries.

Kosters will help oversee the expansion of Antares’ Credit Secondaries investment strategy, which will focus on both GP-led and LP-led credit secondaries opportunities leveraging the firm’s extensive private credit and structuring expertise. Based in New York, Ms. Kosters reports to Benjamin Chapin, Managing Director and newly appointed Head of Liquidity Solutions. Chapin, an 18-year veteran of Antares, most recently served as a senior originator managing relationships with the firm’s private equity sponsors and transactions with its private equity-owned borrowers.

Antares has been a participant in the credit secondaries market, having completed multiple transactions in 2024. In 2025, the firm plans to increase its activity in the space and continue building its dedicated Credit Secondaries team.

“We see a growing opportunity in the credit secondaries market given the maturation of the private credit asset class,” said Vivek Mathew, President of Antares Capital Advisers LLC. “With nearly 30 years of experience as a leading direct lender and manager of one of the largest and most diverse portfolios in the market, we view credit secondaries as a complementary offering to our core direct lending business. We are approaching the market from a credit-expertise perspective and believe Antares is well positioned given our familiarity with the underlying credit assets and extensive working relationships with the managers themselves.”

Kosters joins Antares with an established track record in credit secondaries and more than twenty years of investment experience in private and public capital markets globally. Prior to Antares, Kosters served as Managing Director, co-managing credit secondaries at Apollo Global Management, and previously established the Private Debt Secondaries strategy at Tikehau Capital. Earlier in her career, Kosters held various investment and advisory roles at StepStone, Zurich Insurance Group and the European Bank for Reconstruction and Development.

“I am delighted to join a firm that is considered one of the leading private credit managers with a demonstrated track record built over multiple decades,” added Kosters. “By leveraging the firm’s extensive credit investing and underwriting expertise, I am confident that we can build a market-leading credit secondaries franchise that will benefit the firm’s deep network of investors globally.”

“I’m excited to welcome Olga to the Antares team,” said Chapin. “Her extensive investment expertise and history of driving strong performance will be key as we focus on creating lasting value for our partners.”
