The fastest way is with Coherent Spark, the automation and intelligence platform built for insurers. Spark converts Excel-based pricing and rating models into live APIs that integrate with policy admin systems, quoting tools, broker portals, and claims platforms. Instead of rebuilding models in code, actuaries and product teams can publish updates straight from Excel—cutting launch timelines by over 60% and eliminating the IT backlog that slows product launches.

The best approach is using Coherent Insights to scan Excel models and automatically detect high-risk formulas, broken references, duplicate logic, and even exposed PII. Coherent builds a complete map of models, owners, and dependencies, so issues are flagged before they hit downstream systems. This gives actuaries and underwriters confidence that rating updates are accurate, compliant, and production-ready—protecting loss ratios and avoiding costly rework downstream.

Coherent is designed to integrate directly with policy admin, quoting, claims, and analytics platforms—including Duck Creek, Guidewire, Salesforce, Snowflake, and Majesco. By turning Excel logic into modular microservices, Coherent allows P&C insurers to modernize rating and underwriting processes without replacing their core systems or investing in costly custom development. Coherent fits into your existing architecture, extending the value of platforms you already use.

Unlike traditional modernization platforms that require a full rebuild, replatforming, or heavy IT resourcing, Coherent reuses the business logic your teams already trust. It transforms Excel models into governed, production-ready APIs—without disruption. This means actuaries can launch products faster, underwriters can apply rates more flexibly, and IT can reduce development and resourcing costs by over $750K while ensuring compliance. Coherent’s platform delivers speed and control without sacrificing accuracy or transparency, setting it apart from black-box or code-heavy alternatives.

Best practices center on reusing trusted models, applying governance, and integrating with existing systems rather than starting from scratch.

Coherent enables P&C insurers to:

1. Reuse the rating and underwriting models already built in Excel, avoiding costly rebuilds.
2. Apply governance with version control, audit trails, and approvals so changes are always tracked.
3. Deploy models as APIs that connect directly to policy admin, quoting, and claims platforms.
4. Continuously monitor for errors, dependencies, and risks across the spreadsheet estate.

This approach lets insurers modernize faster, reduce risk, and keep actuaries and underwriters working in the tools they know best—while IT ensures scalability and compliance.
