Build it, buy it, or bridge?
When building makes sense
Consider an internal build for portfolio aggregation, underwriting thresholds, and disclosure workflows. Open data and research models provide inputs. The latest research did not find a named institutional production replacement for the maintained peril-model core.
When buying makes sense
Buying earns its keep when you need peril science, maintained hazard models, validation, and usable documentation. Compare the vendor’s coverage with the staff, integrations, and controls an internal option would need. Custom extensions can remain useful without replacing the core.
