Mosaic launches AI-enabled digital underwriting system

Mosaic Insurance has launched Halo, a digital underwriting system designed to quickly bring complex specialty products to the small and mid-size enterprise (SME) market.

With the use of artificial intelligence, the initiative combines broker trading activity, underwriting decisions, and portfolio outcomes in a single operating environment, the Bermuda specialty insurer said.

Mitch Blaser, Mosaic cofounder and co-CEO said it is a quantum transformation for Mosaic in capability, market reach, and opportunity, all enabled by AI.

He said: “Halo reflects our broader AI strategy: using technology to augment underwriting, leverage data and enable our teams to deploy their expertise more efficiently and at greater scale.”

Mosaic said Halo is a modular AI infrastructure for the SME business, rather than a single-product quoting platform. It allows Mosaic to develop, launch, and refine products, territories, and distribution arrangements without having to continually rebuild the underlying technology and operating model.

“Halo gives us the infrastructure to build and scale specialty products in ways not commonly available today,” said Liam Jones, CEO of Mosaic’s agency business.

“True digital trading, genuine augmentation of information, and real-time active portfolio management is the progress we’ve all been seeking for many years.”

Designed to accommodate brokers’ preferred ways of working, Halo’s AI-driven process invites submissions through e-mail, API (Application programming interfaces) integration, or its portal — allowing brokers to use the channel that best fits their existing workflow.

Once received, the system automatically structures, enriches, and organises submission data for underwriting, reducing the need for follow-up questions or repeated touchpoints, allowing submissions to move swiftly, with faster progression to underwriting.

Eligible risks can move through an automated quote, bind and issuance process in minutes, while exceptions and more complex risks are directed to dedicated underwriters. Notably, HALO allows Mosaic to assess the entire submission funnel — from submission patterns, conversion and risk quality to pricing, limits, retentions, coverage and distribution.

“Halo gives us a clear view of the portfolio as it develops and helps identify where exposure may be accumulating across industries, technologies, service providers and other exposure units,” said George Cole, Mosaic’s Head of SME Cyber — the first product to be launched under the new platform and currently accessible through North America wholesale broker partners.

“The visibility Halo gives us is particularly important in cyber, where a single event or vulnerability can affect multiple insureds at the same time,” said Cole. “It will also be increasingly relevant as we expand Halo into our other specialty products with their own aggregation and concentration risks.”
