Case Study: Marsh boosts dev productivity 5x with CAST AI-powered tech debt remediation

Marsh boosts dev productivity 5x with CAST

Marsh, a leading global professional services firm, faced the challenge of managing technical debt across its vast portfolio of nearly 2,000 custom-built applications built on multiple technologies. With manual remediation proving unscalable, they partnered with CAST to tackle the volume and complexity of these issues.

CAST provided a solution using CAST Imaging to map application architecture and feed deterministic context into an AI-powered workflow for remediation. This resulted in a 93% first-time fix rate for AI-generated code and a 5x productivity gain for development teams, far exceeding typical AI-only benchmarks. The implementation also led to a 63% reduction in structural flaws.
