RiverStone International, which is active in the acquisition and management of non-core commercial and captive insurance liabilities, has unveiled a new group chief executive officer.

Paul Brockman (pictured) will take the reins from Luke Tanzer who will be retiring later this year. It has also appointed Andrew Creed as group president in addition to his role as group chief financial officer.

Brockman will join RiverStone from the Enstar Group where he has most recently served as group chief commercial officer. He has spent more than 30 years in the legacy sector and has significant experience in the US, London, Bermuda and international markets. He is expected to join in January 2026.

Since 2010 RiverStone has completed 47 transactions acquiring $17.7 billion in gross liabilities. In 2024 the group reported $300 million in adjusted profit before tax with a 19.1% return on opening adjusted tangible book value.

Preben Prebensen, chairman, said: “I would like to add my congratulations to Luke for everything he has achieved at RiverStone. He is retiring with the business in a very strong position, and it will be in very good hands with Paul and Andy and the rest of the executive team going forward.”

Tanzer added: “It has been a privilege to be part of RiverStone’s incredible journey over the past 27 years and to have led the company for the past 16 years. I am extremely proud of what we have achieved which is down to all the hard work of the fantastic team at RiverStone. I would like to extend a very warm welcome to Paul, who is an inspired choice as our next CEO, as well as my deepest congratulations to Andy who has been a brilliant partner over the past 12 years. Together I’m sure Paul and Andy and the rest of the team will take the company forward to new heights of growth and success in the years to come.”
