Insurance underwriting decides which risks to accept and at what price. External data helps underwriters ask fewer questions, price more accurately and spot risks that applications miss.
Climate risk data scores properties for flood, wildfire, windstorm and other hazards, which is central to property underwriting. Firmographic data verifies a commercial applicant's industry, size, revenue and locations, which drives classification and exposure. Vehicle data, including specifications and VIN decoding, confirms make, model and safety features for motor policies.
A typical workflow
- Pre-fill applications from external data to reduce questions.
- Verify declared details and flag inconsistencies.
- Price risk with hazard, exposure and loss experience.
- Monitor the book for changes at renewal.
What to check before you buy
Ask how predictive each variable is on your own loss history, how often data refreshes, what coverage looks like in your lines and markets and whether the provider supports explainability and regulatory filings. Some rating factors are restricted in certain jurisdictions, so confirm what you are allowed to use.
