Neither Duck Creek nor Reserv is proven to be quietly dominating AI insurance. They offer different kinds of products: Duck Creek markets a broad property-and-casualty insurance core platform, while Reserv describes claims-focused technology and services that work with adjusters. That makes a simple winner-versus-winner ranking misleading. The useful comparison is which part of an insurer’s operation you need to change—and what evidence each vendor can provide for your specific workflows.
What is the difference between Duck Creek and Reserv?
Duck Creek positions its software as an insurer core platform spanning policy, rating, billing, claims, reinsurance, and policyholder-facing capabilities. Reserv describes AI-powered claims technology and claims services, with analysis alongside adjusters from first notice of loss (FNOL) through settlement. Based on these descriptions, Reserv should not be treated as a direct replacement for a full policy, billing, and rating core.

What Duck Creek’s AI announcement does—and does not—show
On April 28, 2026, Duck Creek announced an insurance-native Agentic AI Platform intended to deploy, orchestrate, and govern agents across the insurance lifecycle. The announcement names an Agentic Underwriting Workbench and Agentic First Notice of Loss experiences, and describes integration with Duck Creek systems of record. This indicates the company’s stated product direction; the announcement alone does not establish customer adoption, availability for every insurer or line of business, or independently measured improvements.
Duck Creek CEO Hardeep Gulati described the strategy this way: “Agentic AI will redefine how insurance operates—enabling carriers to move from manual, fragmented processes to orchestrated end-to-end decisioning and support for all personas to drive better outcomes and continuously improve.” This is the CEO’s characterization of the intended change, not independent evidence that those outcomes have occurred.

What Reserv says its AI does in claims
Reserv’s stated focus is claims rather than an insurer’s entire core stack. Its About page describes AI-powered technology supporting claims analysis in partnership with adjusters, from FNOL through settlement, alongside data science, reporting, and APIs for insurance stakeholders. That description points to a claims workflow and operating model; it does not establish that Reserv supplies the policy administration, rating, and billing capabilities Duck Creek markets.
The available Reserv page does not provide a like-for-like, independently measured comparison with Duck Creek, nor comparable figures for customer count, claims volume, or outcomes. Evaluate Reserv against a defined claims workflow and ask for evidence tied to the relevant line of business and operating conditions. See Reserv’s description.
Do the published scale figures prove that Duck Creek is dominating?
No. Duck Creek’s homepage reports 390+ customers globally, 1,200+ successful implementations, and 30 million+ claims processed via OnDemand. Its claims page reports more than 60,000 claims per day during a catastrophe event and says an assignment or claims-workflow rule change can be made in fewer than one day. These are Duck Creek-published figures accessed October 4, 2026; the pages do not give figure-specific publication dates, and the claims figures are vendor-reported. They describe scale or capability, not a head-to-head AI performance result. The reviewed Reserv sources do not state comparable figures, so the numbers cannot fairly be used to rank the two companies. Duck Creek homepage · Duck Creek claims page.

“Dominating” would require evidence such as comparable market share, deployments, or independently assessed outcomes. The reviewed sources establish vendor positioning and company-published claims, not that either company leads the other in AI insurance.

How insurers should compare the offerings
Start with the business problem, not the AI label. A carrier assessing a core-platform change has a different decision from one seeking claims capacity or claims-analysis support. Compare the offerings against the same workflow and request evidence that fits the insurer’s own environment.
- Scope: Identify whether the need is policy, rating, billing, claims, or a narrower claims-service workflow. Confirm which capabilities are included in the proposed product and which remain in existing systems.
- Operating model: Establish whether the insurer will license and operate software, use a claims service, or combine technology with adjuster support. Clarify who owns configuration, daily operations, and exceptions.
- Integration: Map connections to current policy, billing, and claims systems. Ask about APIs, data access, integration responsibility, and how records move between systems.
- AI governance: Request details on human review, auditability, explainability, and controls for consequential decisions. Ask how an insurer can monitor decisions and handle exceptions.
- Evidence: Request named customer references and results for the relevant line of business, geography, and workflow. Separate vendor-reported claims from independently measured results.
- Commercial fit: Compare implementation scope, ongoing operating responsibilities, total cost, and contract terms. The reviewed sources do not provide comparable pricing or implementation details.
Guidewire is a separate company, not another name for Reserv. Its own site describes an AI strategy within P&C core applications and workflows; it should not be silently substituted for Reserv in a Duck Creek-versus-Reserv comparison. Guidewire Insurance AI.
