A case study by Praxent

How AI helped modernize a legacy professional liability core system without breaking the business

A professional liability provider had reliably delivered coverage for its members for over 40 years.

But their success relied precariously on decades of institutional knowledge stored in a decades-old platform that was only fully understood by one person.

Even with highly capable teams, outdated UI and fragmented workflows meant their system couldn’t integrate with modern tools or provide the digital experiences their policyholders expected. Manual processes created operational bottlenecks and compliance risks, increasing costs while limiting growth.

The Right Partner for High-Stakes Modernization
This liability provider needed to future-proof their systems without breaking what worked, so they partnered with Praxent for our AI modernization capabilities and deep insurance expertise, including professional liability, workers’ comp, and specialty lines.

The AI-Powered Breakthrough
By combining AI with software engineering, we reverse-engineered millions of lines of business logic within the legacy code, systematically parsing them to extract:

Rating calculations and underwriting rules shaped over decades

Claims workflows and approval hierarchies

Regulatory compliance logic and reporting processes

Integration dependencies across systems

AI outputs were validated by our expert engineers to ensure accuracy and compliance. This created permanent documentation of the “black box” and revealed additional modernization opportunities.

The result

Building modern core systems that keep what works

Armed with the extracted business logic, Praxent rebuilt the system on a modular, cloud-ready platform that preserved what worked while providing future flexibility.
Every edge case and exception was mapped, so nothing was lost.
