Independent rating validation for P&C insurance carriers

Right premium. Proven to the cent.

An independent premium, calculated from your approved rates and rules, that must equal your policy system’s premium on every case you run. For every rate change, bureau update, new state and platform move.

Guidewire’s first testing technology partner Built on Karate, used across the Fortune 500 Runs inside your network. Nothing calls home.

The problem

Premium leakage never throws an error.

A mis-keyed factor, a deviation that stopped applying, an edition picked on the wrong date. Your system still returns a plausible premium. So the error surfaces late: as leakage nobody measured, or as a refund with interest. Spreadsheet macros and a few dozen hand-picked scenarios only catch the cases someone thought of.

From the public record

$4M+

refunded by one carrier, with interest, on fewer than 400 policies, after it found its own rating error.

Most of those policyholders had already left.

What VeriQuant does

One bar answers the four questions that follow.

Every case is a match, or a mismatch that names the first step where the two calculations part ways. Anything unexplained stays open. Never counted as passed.

Edition

Does the system rate what you filed, for the right effective date?

Rows

After a rate change, did only the intended rows move?

Leaked

What has already leaked on the policies you have written?

Platform

When you move platforms, does the premium hold?

For your role

The same check. Three jobs done.

Proof

The bar isn’t ours. A carrier wrote it.

A large commercial carrier wrote it into its own acceptance criteria: the simulator’s premium must equal the policy system’s premium, on every case, to the cent. It is the bar we are measured against today. You can open a public example report built the same way.

“Guidewire decided to leverage Karate Labs for our Testing Framework: a powerful, open-source, industry-standard technology designed to make testing automation simple and accessible.”

The next step

Bring us the rating case you worry about most.

A rate revision. A bureau update. A new state. An edge case nobody trusts. In 45 minutes, a senior member of our team walks your VP of Pricing, Head of QA and CIO through how the simulator is built for that case, and how your team runs the comparison in your own QA environment, exactly as you test today.

  • The three flows on your case: set-up, the change, the back-test
  • A live run of the private rate-revision demo, on synthetic data
  • A scoped build for one line of business and one state, then a demo and an evaluation on your rates
