Smith joins Mosaic as Americas CEO

Toby Smith (pictured) joins Mosaic Insurance as the insurer’s Americas CEO, effective 23 July.

Based in New York, Smith becomes a member of the specialty insurer’s leadership team, with responsibility for market engagement and profitable growth across the US, Canada, and the wider Americas region.

This includes transactional liability, cyber, and environmental liability, the largest three divisions at the insurance company, which launched in 2021.

Smith has more than 20 years’ experience in the specialty insurance industry, most recently as chief underwriting officer of North America specialty lines at Liberty Mutual.

He previously worked with Mosaic’s leadership at Ironshore from 2009, launching its environmental business, holding roles including president of environmental and president of excess and surplus lines casualty.

He began his insurance career at AIG, where he managed a team in its environmental claims and coverage unit.

“Toby is a longtime colleague with an exceptional track record that has seen him build the largest environmental business in the market,” said Mosaic’s co-CEO Mitch Blaser.

“He will be instrumental in continuing our growth trajectory and accelerating our strategic ambitions across specialty product lines globally and in the critical US region. As he joins our impressive team, we look forward to creating significant value for our stakeholders, partners, and customers.”

Co-CEO Mark Wheeler said: “Our unique underwriting agency structure and syndicated products are delivering an impact across global markets, and the appointment of a high-caliber leader like Toby demonstrates our commitment to driving further profitable expansion through the Americas.

“As we gather momentum, he is the right person at the right time to scale up our business and help us seize the great opportunities ahead, and we look forward to working with him again.

Smith added: “I’m thrilled to join Mosaic at this stage of its tremendous growth, and I look forward to working with its dynamic team—including Mitch, Mark, and other former colleagues—to deliver expansion, innovation, and success.

“Mosaic is a young company that in a short time span has won recognition and market respect for its differentiated model, leading underwriters, and highly specialized business lines. The opportunity to join that journey and help shape its roadmap for the future is energizing.”
