Julianna Muir has been appointed head of strategy and innovation at Hamilton USA.

Ms Muir has worked for the company since 2015 and has been promoted to the newly-created position. She will be a “key participant and leader in designing and executing the strategy for Hamilton USA”, according to a statement by the company.

She will also support a planned expansion into the middle market business segment, and ongoing development of Attune, Hamilton’s small commercial venture with AIG and Two Sigma.

Hamilton USA is the US insurance platform of Bermudian-based Hamilton Insurance Group.

“In the four months since I joined Hamilton USA, I’ve had the opportunity of working closely with Julianna,” said Seraina Macia, chief executive officer of Hamilton USA.

“As we worked with our partners to launch Attune and then turned our attention to a middle market strategy, I’ve been constantly impressed by her strategic thinking and tactical execution as well as her grasp of industry dynamics and trends.

“Julianna’s new role aligns her significant skills with our goal of using data science and analytics to transform the underwriting process. We’ve done this with Attune and I have no doubt we’ll be able to do the same thing with the larger risks represented in the middle market segment.”

Ms Muir has a master’s in business administration from The Wharton School, University of Pennsylvania. Before joining Hamilton USA she worked for McKinsey & Company.
