Appian joins InsureMO to streamline specialty insurance

September 16, 2025

InsureMO has partnered with Appian, a software company specialising in process automation and AI, to launch a unified underwriting platform for the United States Excess & Surplus (E&S) specialty insurance market.

The alliance addresses long-standing challenges in the E&S sector, which often faces manual processes and IT bottlenecks, according to InsurTech Insights.

Combining InsureMO’s enterprise-grade Excel Rater with Appian’s AI-powered Connected Underwriting Workbench, the platform aims to accelerate product launches, enable real-time pricing updates, and simplify management of non-standard risks.

InsureMO’s Excel Rater integrates directly with the workbooks already used by underwriting teams.

By removing file conversions and repetitive configuration, underwriters and product managers can instantly update rating tables and formulas, improving speed to market while supporting high-volume processing.

Appian’s Connected Underwriting Workbench adds a single interface to manage the full submission lifecycle. It streamlines workflows, unifies data from multiple sources, and maintains compliance and auditability, helping underwriters focus on high-value decisions.

The joint system is available now, offering rapid deployment and seamless integration with insurers’ existing systems to help carriers innovate and remain competitive.

“The E&S market is defined by its need for agility and precision,” said Rajat Sharma, Chief Revenue Officer at InsureMO. “With our enterprise-grade Excel Rater platform, underwriters and product managers can make real-time updates to rating logic and deploy changes instantly, without relying on IT. By integrating this capability with Appian’s robust Connected Underwriting Workbench, we’re enabling insurers to innovate at speed and scale-empowering them to respond to emerging risks, launch new products faster, and deliver tailored solutions with confidence.”

“Our partnership with InsureMO delivers a best-in-class solution for E&S insurers,” said Shyam Somani, Global Head Insurance Solutions at Appian. “By combining Appian’s Connected Underwriting Workbench with InsureMO’s Excel Rater, underwriters can now evaluate and price risk in a single platform, empowering insurers to reduce time to quote, minimize risk, improve profitability, and elevate the customer experience. This joint solution is designed to scale with our clients’ growth and help them stay ahead in a rapidly changing market.”
