Neptune Insurance Holdings (Neptune Flood)

Triton automated flood underwriting engine

Neptune's Triton engine underwrites flood policies in under two seconds with no human underwriters

WorkingCompany's own claim

Problem

Flood insurance underwriting involves risk selection, pricing, aggregation and carrier assignment, which are slow when done by hand.

Approach

Neptune built Triton on its own AI and machine-learning models. It handles risk selection, pricing, aggregation and carrier assignment, and Neptune runs underwriting without human underwriters. Triton also uses KatRisk APIs to overlay flood footprint data onto exposure after a natural disaster.

Results

under 2 secondstime for Triton to complete underwriting decisions, per NeptuneCompany's own claim[1]
24.7%lifetime written loss ratio of the Triton engine from Neptune's 2016 inception through June 30, per Neptune; it covers the whole book of businessCompany's own claim[1]

Takeaway

Neptune runs its entire underwriting step through one model. The loss ratio it cites covers the whole business since 2016, so it does not isolate the effect of the AI.
