Hamilton Insurance taps Raymond Karrenbauer as CIO – Insurance Business America

By Kenneth Araullo
Bermuda-based re/insurer Hamilton Insurance has appointed Raymond Karrenbauer (pictured above) as group chief information officer, effective Sept. 15.
He will take over from Venkat Krishnamoorthy, who is retiring on Aug. 30. Krishnamoorthy joined Hamilton in 2019.
Before joining Hamilton, Karrenbauer held executive roles at The Cybersecurity Maturity Model Certification Accreditation Body, Inc. (The Cyber AB), where he was executive vice president and CFO from 2021. His remit there included strategic oversight of IT in support of the US Department of Defense’s contractor cybersecurity compliance program.
Karrenbauer also served as senior vice president and CIO at IFG Companies, where he led digital transformation and operational efforts. Prior to that, he held senior roles at Axis Capital and ING Group.
Karrenbauer will join the executive management team and report to Craig Howie, group chief financial officer.
Hamilton CEO Pina Albo said technology enablement remains a key business priority, noting that Karrenbauer’s experience positions him to lead this development.
“As a results-driven leader with an impressive track record of innovation and execution, as well as a deep understanding of the insurance industry, Raymond will ensure we continue to enhance our technological capabilities and deliver exceptional value to all our stakeholders,” Albo said.
The appointment comes as Hamilton continues to strengthen its leadership structure. In May, the company added Karen Green and David Priebe to its board of directors. Both bring industry and governance experience, with Green previously serving as non-executive chair at Aspen Insurance UK and Priebe having held several senior roles at Guy Carpenter.
The leadership changes extend beyond the boardroom. Earlier this year, Hamilton named new CEOs for its Bermuda and London operations – Colin Shelly and Adam Beatty, respectively.
Shelly, previously chief accounting officer, took over the Bermuda unit while Beatty transitioned from his role as group head of specialty to lead the London platform.
Karrenbauer’s appointment also coincides with a period of financial growth for Hamilton. In its most recent earnings report, the company posted Q1 2025 net income of US$81 million, alongside gross premiums written of US$843.3 million – a 16.8% increase from the same period last year.
