Corgi vs Testudo: Which AI Insurance Fits?

Corgi vs Testudo: Which AI Insurance Fits?

Both Corgi and Testudo come up when a company starts shopping for insurance against AI risk, but they are structured very differently. Corgi is a full-stack insurance carrier for startups that folds AI coverage into a broader program; Testudo is a Lloyd's of London coverholder that writes a single, standalone generative AI liability policy. The right pick depends on whether you want most of your startup's insurance in one place or a dedicated policy built for AI exposure.

This is an independent comparison from QuoteSweep, which maps the modern commercial insurance landscape. QuoteSweep does not compete with any of these companies.

TL;DR: Corgi is an AI-native, full-stack carrier that underwrites and issues modular startup policies itself, packaged by funding stage, with AI risk covered through its tech and AI liability (technology E&O) line. Testudo is a Lloyd's coverholder writing a standalone, claims-made generative AI liability policy up to $10M per insured across all 50 states on an excess and surplus basis. Corgi is breadth (a full stack with AI included); Testudo is depth (one dedicated AI policy backed by Lloyd's). Neither publishes pricing. Both sit inside the emerging ai-agents hub.

The one-line difference

Corgi bundles AI into a broad startup insurance package and sells it as a carrier; Testudo writes a single, standalone generative AI liability policy through Lloyd's, aimed at mid-market US companies.

Model and coverage

Corgi is a licensed, full-stack, AI-native carrier that underwrites, prices, issues, and services policies itself, with "no middlemen." Its coverage is modular and packaged by funding stage from pre-seed to growth, spanning commercial general liability, cyber, tech and AI liability (technology E&O), D&O, EPLI, fiduciary, media liability, and hired and non-owned auto. AI-specific risk, such as output errors and hallucinations, is handled inside its tech and AI liability (technology E&O) line. The buying experience is built for founders: a self-serve application with quotes in minutes and same-day binding. Per third-party reporting, Corgi has raised about $378M in total, most recently a $106M Series B1 at a reported $2.6B valuation.

Testudo is narrower and deeper. It operates as a managing general agent and coverholder for Lloyd's of London, writing a dedicated claims-made policy, not an endorsement, that responds specifically to generative AI losses. That policy covers AI hallucinations and negligent errors, IP infringement and personal injury (copyright, trademark, libel, slander), unauthorized data disclosure, bodily injury from reliance on AI outputs, property damage from AI-generated recommendations, and regulatory proceedings and fines. It writes on an excess and surplus basis across all 50 states, with A+ (Superior) rated capacity and limits up to $10M per insured. Testudo says it underwrites using a dataset of real AI litigation and its own "AI Risk Engine," and can provide an indication in days with no access to your code, no audits, and no integrations.

Side by side

Who each fits

Corgi fits you if you are a funded startup or technology company that wants a full insurance stack in one place, with AI coverage part of it rather than a separate specialist policy. The pitch is breadth and speed: modular lines packaged by stage, a quote in about five minutes, and same-day binding.

Testudo fits you if your priority is standalone, Lloyd's-backed generative AI liability, especially as standard commercial general liability forms add generative AI exclusions in 2026. It is a dedicated policy, not an endorsement, with up to $10M limits, A+ rated capacity, and a low-friction underwriting path (an indication in days, no code access).

If your core exposure is autonomous agents specifically, rather than generative AI outputs, it is also worth comparing options across the ai-agents hub.
