Among the new CIO's achievements, he played a key role in transforming his former firm from a UK-focused business into a global asset manager with over $1.5 trillion in AuM.

Robeco has appointed Anton Eser (pictured) as chief investment officer (CIO) and a member of its executive committee, effective 1 September 2025. Eser will be succeeding Mark van der Kroft, who will be retiring on 1 October 2025 after having served as CIO at Robeco since 2020, the firm said in a statement.

Eser, who has 25 years of experience in global financial markets, spent 13 years at Legal & General Investment Management (LGIM), where he was appointed CIO in 2016. During his tenure, he played a key role in transforming LGIM from a UK-focused firm into a global asset manager with over $1.5 trillion in assets under management. He played a part in LGIM’s ESG integration across investment teams and was instrumental in developing the Future World fund range.

Since 2021, Eser was CIO at 10X Investments, a fast-growing fintech firm specialising in multi-asset solutions for the South African market. Earlier in his career, he specialised in global fixed income markets as both an investor and team leader. Eser began his fixed income career at Aegon UK before joining LGIM in 2006, where he launched and led the firm’s global credit business. In 2013, he was appointed co-head of global fixed income, taking on responsibility for a wide range of strategies and teams across the fixed income platform.

Acknowledging van der Kroft's contribution to the business, Karin van Baardwijk, CEO at Robeco said: “He has played an essential role in shaping Robeco’s investment philosophy and culture, and has been instrumental in building the successful company we are today. We wish him all the best in his well-deserved retirement.” 

Founded in 1929, Rotterdam-based Robeco has 15 offices worldwide and €214 billion ($252 billion) in total client assets.
