Neptune Insurance

Established in 2018, Neptune offers flood insurance to both homeowners and businesses. The demand for flood coverage in the United States has intensified as climate change drives more frequent and severe storms, putting millions at risk of costly damage.

The company’s automated underwriting platform, Triton, leverages artificial intelligence and data science to manage functions like risk assessment and pricing.

According to Neptune, Triton has sustained a lifetime written loss ratio of 24.7% from its launch through June 30, 2025—a period that included major U.S. flood events such as Hurricane Helene and Hurricane Milton last year, Reuters reported.
