Mosaic Insurance opens second US office in Chicago

April 12, 2022

Hamilton, Bermuda—Mosaic Insurance has opened an office in Chicago, IL, its second US physical location, for a growing number of employees.

“The new Chicago office underscores our focus on the important North American market, where we source a large portion of our business,” said Co-Founder & Co-CEO Mitch Blaser. “We’re thrilled to add the city to our strategic network of underwriting hubs that give us access to global specialty risks.”

Located in the city’s Loop, at 318 West Adams Street, the office is Mosaic’s fourth globally, joining addresses in New York, London, and Bermuda. The location accommodates most of the company’s North American cyberrisk specialists, led by Global Head of Cyber Yosha DeLong, as well as Mosaic’s Global Head of Transactional Liability, Bill Monat.

“Chicago represents another milestone in Mosaic’s build-out and will be an important North American location for us as we continue to develop our teams and business lines,” said Chief of Staff Lisa Fontanetta. “We’ve had employees based there since last year, but this consolidates our presence in the city and highlights our focus on in-person collaboration and partnership.”

Mosaic launched in February 2021, with new Lloyd’s Syndicate 1609 as its centerpiece and a focus on six targeted lines of business, including political risk, political violence, financial institutions, and professional liability, along with cyber and transactional liability. The company plans to add more underwriting offices this year, in Europe, Canada, the Middle East and Asia.

“Chicago is an important location for us, not only geographically, allowing us to service clients on both US coasts, but also as a significant hub of insurance,” said DeLong, who currently oversees a team of eight across US, UK and Bermuda jurisdictions to meet rising demand for cybersecurity coverage.

“Amid economic and geopolitical uncertainty and the challenges of cross-jurisdictional exposures,” she added, “we aim to offer solutions.”
