Bigger, better, bolder - Check out our new look!

It’s now easier than ever to learn more about what it’s like to partner with Rokstone CRU and find the best team member to contact with a new enquiry or question.
A lot has happened since we founded Rokstone CRU in 2018, and now was the right time to align the business more closely with the wider group, which now controls over $600m GWP globally, across multiple specialty lines portfolios. CRU has continued to add the best talent, launch new products and make investments in value added services which bring true value to our partnering brokers.
Rokstone Group has continued its own impressive organic growth in the five years it has been in existence, launching into several new lines of business, including Marine Cargo, Power & Energy and US Livestock. Rokstone CRU has itself launched a new Lead Excess program, and this entrepreneurial spirit will be a hallmark of the whole Group going forwards.
Rokstone is part of Aventum - an independent and global Group focused on the provision of specialty insurance and reinsurance underwriting and broking.
Aventum provides Rokstone with the core central services to fuel its continued success. Services include marketing, risk management, finance, compliance, HR, actuarial data science, and IT & operations.
Aventum has over 240 staff operating from 14 offices around the world, trading across six continents, and controlling in excess of $700m GWP.
Our rebrand and new website are just part of our strategy to continue to attract world-leading new talent to join Rokstone CRU and support our broker and capacity partners.
