Coalition

Coalition is a San Francisco–headquartered cyber insurance and active risk management provider founded in 2017 by Joshua Motta (CEO) and John Hering. Coalition pairs commercial insurance lines — Cyber, Technology Errors & Omissions, Executive Risks (D&O, EPL, Fiduciary, Crime), Miscellaneous Professional Liability, and AI coverage — with a continuous attack-surface monitoring and incident-response platform (Coalition Control, Wirespeed ADR, Coalition Incident Response, Security Awareness Training). The company's underwriting engine is exposed to brokers and distribution partners through the Coalition Active Insurance API, a RESTful surface that supports rate, quote, bind, document generation, renewals, and webhook events across the United States and Canada, with executive risks APIs and additional product lines added over time. Coalition also publishes a public Exploit Scoring System (ESS) API at ess-api.coalitioninc.com that exposes CVE detail, ESS/EPSS/CVSS scoring, exploit references (ExploitDB, Metasploit), GitHub repository signals, and Twitter mention timelines for over 200,000 vulnerabilities. Coalition is backed by Allianz X, Valor Equity Partners, Ribbit Capital, Mitsui Sumitomo, Kinetic Partners and other strategic insurers (Allianz, Arch, Ascot, Zurich, Swiss Re, Lloyd's syndicates); it raised a $250M Series F in 2022 at a $5B valuation. The Active Insurance API is partner-gated (no public OpenAPI), but the ESS API is fully public with OpenAPI 3.1, an interactive docs UI, and ReDoc.

Coalition publishes 1 API on the APIs.io network: Cve API. Tagged areas include Cyber Insurance, Insurance, Insurtech, Risk Management, and Cybersecurity.

The Coalition catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

Coalition’s developer surface includes engineering blog, YouTube channel, and 23 more developer resources.
