InsureMO and Appian Unite to Deliver Enterprise-Grade Underwriting Innovation for US E&S Specialty Insurance

McLean, VA - September 9, 2025 - InsureMO, the global leader in insurance middleware, today announced a strategic partnership with Appian (Nasdaq: APPN), a leader in process orchestration, to launch a unified underwriting solution tailored for the US Excess & Surplus (E&S) specialty insurance market. This collaboration brings together InsureMO's enterprise-grade Excel Rater platform and robust API ecosystem with Appian's advanced, AI-powered Connected Underwriting Workbench, setting a new benchmark for speed, flexibility, and operational excellence in E&S insurance.

The US E&S market demands rapid product launches, continuous pricing evolution, and seamless management of non-standard risks. Traditional rating and underwriting systems often struggle to keep pace, resulting in manual workarounds, IT bottlenecks, and missed market opportunities. The new InsureMO-Appian solution directly addresses these challenges by empowering carriers, and MGA to automate complex workflows, integrate data effortlessly, and deploy custom rating logic-all within a single, scalable platform.

InsureMO's Excel Rater is an enterprise-grade platform that executes premium calculations directly against the same Excel rating workbooks underwriting teams use every day-no file conversion, re-keying, or bespoke templates required. Leveraging these familiar assets as the single source of truth eliminates manual configuration effort and removes ongoing IT dependencies whenever rates change. Underwriters and product managers can update tables and formulas themselves, accelerating time-to-market-an essential advantage for specialty and E&S carriers whose pricing evolves continuously. The platform delivers these productivity gains without sacrificing performance or scalability, ensuring consistent, high-volume processing across the business.

"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."

Appian's Connected Underwriting Workbench complements this flexibility with a unified interface that manages the entire submission lifecycle, streamlines and accelerates workflows through automation, and integrates data from multiple sources to provide a single-pane-of-glass view. Its AI-driven workflow automation helps underwriters focus on high-value decisions, while ensuring every step is tracked for compliance and auditability.

"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."

The integrated InsureMO-Appian solution is available now for US E&S specialty insurers, offering rapid deployment, seamless integration with existing systems, and the ability to handle high-volume, complex business with ease.
