What Envelop Risk does

Envelop Risk is a UK-headquartered specialty reinsurance underwriting firm that focuses on cyber and other emerging risks. Founded in 2016 in Bristol by Jonathan Spry and Paul Guthrie, the company underwrites treaty reinsurance for cyber risk using a proprietary AI-driven analytics platform called CyberTooth, which processes firmographic, economic, technical, and claims data on millions of companies combined with continuous cyber threat intelligence from in-house OSINT/CSINT teams. Under its "Augmented Underwriting" approach, the platform combines machine-learning models with human underwriters and cyber threat experts to deliver risk estimation, capital management, and portfolio analytics for cedants. As of December 2024, the firm had written $1 billion in cumulative gross written premium since beginning underwriting in 2018, at a 40% compound annual growth rate, and reported £34.6 million of revenue in 2024.

The firm operates four interlocking business areas: (i) Reinsurance Underwriting via its Bermuda and London platforms, including the Lloyd's SPA 1925 vehicle launched with Apollo in January 2024; (ii) Cyber Partnership Platforms, enabling 30+ cedants globally to enter or expand cyber market participation with Envelop's analytics, A-rated capacity, and modular wordings; (iii) Envelop Capital Markets, which structures indemnity, parametric, and index-based risk-transfer products through the Bermuda-based Class 3A reinsurer Augmented Re for ILS investors; and (iv) Envelop Risk Solutions, an advisory and analytics services business launched in September 2024 covering underwriting strategy, modelling, threat intelligence, and operations automation. Office locations span Bristol (headquarters), London, and Hamilton, Bermuda. The company is privately held, is regulated across multiple jurisdictions (FCA, Bermuda Monetary Authority, US regulators via Binary Insurance Services / DataStream), and has raised approximately $200 million in venture capital including a $130 million Series B led by SoftBank Vision Fund 2 in September 2021.
