Company context
Neptune is a leading, high-growth, highly profitable, data-driven managing general agent that is revolutionizing the way homeowners and businesses protect against the growing risks of flooding. We offer a range of easy-to-purchase residential and commercial insurance products — including primary flood insurance, excess flood insurance, and parametric earthquake insurance — distributed through a nationwide network of agencies. Neptune does not take any balance sheet insurance risk or have claims handling responsibility relating to the policies we sell. We underwrite and administer the issuance of insurance policies on behalf of a diverse panel of insurance and reinsurance companies, whom we refer to as capacity providers, that manage both this risk and the associated claims handling. From day one, we have built our business on a foundation of advanced data science and AI, leveraging proprietary ML algorithms, which has led to superior underwriting results, outsized growth, recurring revenue, and robust margins, including delivering a lifetime written loss ratio of just 24.7% to our capacity providers from our inception through June 30, 2025. In addition, for the year ended December 31, 2024, we achieved 40.6% organic revenue growth, 29.0% net income margin, and 60.4% Adjusted EBITDA margin and for the six months ended June 30, 2025, we achieved 32.3% organic revenue growth, 30.2% net income margin and 59.3% Adjusted EBITDA margin.
