Corgi bundles AI risk into a full startup insurance stack that it underwrites and issues itself — but if AI exposure is your actual concern, a full-stack startup package may be more than you need, or not the right shape. Three specialists take a narrower, AI-first approach: dedicated policies, affirmative coverage, and certification-plus-insurance. Here is how the alternatives compare and who each one fits.
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 modular startup policies itself, with AI risk covered through its tech and AI liability line. If you want coverage built for AI specifically rather than AI folded into a startup stack, compare three specialists on the ai-agents hub: Testudo writes a standalone, Lloyd's-backed generative AI liability policy up to $10M per insured; Armilla pairs affirmative AI liability for generative AI and agents with independent model verification; and AIUC combines the AIUC-1 certification standard, independent audits, and insurance for AI agents. None of the four publishes flat pricing.
The one-line difference
- Corgi is a full-stack, AI-native carrier for startups and technology companies — it underwrites, prices, issues, and services modular policies itself, and folds AI risk into its Tech & AI Liability line inside a broader startup package.
- Testudo is a Lloyd's of London coverholder writing a standalone generative AI liability policy — a dedicated, claims-made form, not an endorsement.
- Armilla is a Lloyd's coverholder writing affirmative AI liability for generative AI and AI agents, paired with independent AI verification.
- AIUC is an AI-agent standards and insurance company that leads with a certification standard (AIUC-1), independent audits, and insurance on top.
The short version: Corgi gives you breadth (a full startup stack with AI included), while Testudo, Armilla, and AIUC give you depth on AI itself — as a standalone policy, an affirmative policy with verification, or a certified-and-insured framework.
Model and coverage
Corgi is not a broker. It is a licensed, full-stack carrier that owns underwriting and claims end-to-end ("no middlemen," per its FAQ), packaging coverage by funding stage from pre-seed to growth. Its modular lines include Commercial General Liability, Cyber, Tech & AI Liability (technology E&O), D&O, EPLI, Fiduciary, Media Liability, and Hired and Non-Owned Auto. Founders can self-serve a quote in minutes and bind the same day.
Testudo writes as a managing general agent and coverholder for Lloyd's, on A+ (Superior) rated capacity, up to $10M per insured across all 50 US states on an excess and surplus basis. Its dedicated claims-made policy covers liability arising from generative AI: hallucinations and negligent errors, IP infringement and personal injury, unauthorized data disclosure, bodily injury from reliance on AI outputs, property damage from AI-generated recommendations, and regulatory proceedings. It says it can provide an indication in days using a dataset of real AI litigation and its own AI Risk Engine — with no code access, no audits, and no integrations.
Armilla is also a Lloyd's coverholder, but it writes affirmative coverage for AI-specific failure modes across both generative AI and AI agents: AI Model Error Liability (underperformance, errors, hallucinations), AI Model Output Liability (confidentiality breaches, defamation), AI Agent Mistakes (escalation failures, incorrect decisions), non-breach privacy and data leakage, AI Model Property Damage Liability, and AI Model Regulatory Violations. Alongside the policy, Armilla conducts independent AI assessments — model verification, bias evaluation, stress testing, and red teaming — plus ongoing monitoring and incident coordination. Its capacity is backed by Lloyd's underwriters and partners including Chaucer, Axis Capital, Convex, Swiss Re, and Greenlight Re, with reported limits up to $25M per organization. Armilla is distributed through brokers.
AIUC puts a standard first. Its centerpiece, AIUC-1, is a certification standard for AI agents built around six pillars — data and privacy, security, safety, reliability, accountability, and societal risks — drawing on established frameworks including MITRE ATLAS. Certification is verified through independent audits by accredited firms (audit and assurance firm Schellman is noted as the first accredited to conduct AIUC-1 audits), and AIUC layers insurance on top that protects enterprises against losses from AI agent failures, with pricing that reflects how safe a system is shown to be.

All funding and capacity figures are company-reported or from third-party reporting and are not independently audited — read them as scale signals, not prices. Note that Armilla's "$25M" is a coverage limit per organization, not a funding round.
Who each one fits
-
Stay with Corgi if you run a funded startup or technology company and want a full insurance stack — general liability, cyber, D&O, EPLI, and more — with AI risk covered inside it, bought self-serve and bound the same day from a single full-stack carrier. Corgi is breadth, not an AI point solution.
-
Choose Testudo if your exposure is generative AI specifically and you want a standalone, Lloyd's-backed policy rather than an endorsement — especially valuable as standard commercial general liability forms add generative AI exclusions. It fits US companies that want up to $10M in limits, all-50-state E&S reach, and a fast, low-friction indication with no code access, audits, or integrations. Best for standalone, Lloyd's-backed generative AI liability.
-
Choose Armilla if you want affirmative AI coverage across both generative AI and AI agents, paired with an independent read on how the model actually behaves — verification, bias evaluation, stress testing, and red teaming — with reported limits up to $25M and Lloyd's-plus-reinsurer capacity. It fits businesses, risk teams, and the brokers who serve them, since Armilla is broker-distributed. Best for AI liability paired with independent model verification.
-
Choose AIUC if you are an enterprise adopting AI agents (or an AI vendor trying to earn enterprise trust) and you want a certified-plus-insured approach: a public standard (AIUC-1), independent third-party audits, and insurance priced to how safe the system is shown to be. The certification doubles as a trust credential a vendor can show a cautious buyer. Best for a certified-plus-insured approach to AI agents.
For most buyers the deciding factors are whether you need a full startup stack or dedicated AI coverage, whether you want a standalone policy (Testudo), affirmative coverage with verification (Armilla), or a certification-backed framework (AIUC), and how you prefer to buy — direct, through a broker, or via certification and audit.
Frequently Asked Questions
Are these true alternatives to Corgi?
They solve overlapping problems from different angles. Corgi is a full-stack startup carrier that includes AI risk in a broader package it underwrites itself. Testudo, Armilla, and AIUC specialize in AI-specific liability — as a standalone policy, an affirmative policy with verification, or a certified-and-insured framework. If your main concern is AI exposure rather than a full startup insurance stack, the three specialists are the closer fit.
Which one covers AI agents, not just generative AI?
Armilla writes affirmative coverage for both generative AI and AI agents (including agent mistakes such as escalation failures and incorrect decisions), and AIUC's entire model — the AIUC-1 standard, audits, and insurance — is built around AI agents. Testudo focuses on generative AI liability. Corgi covers AI risk through its Tech & AI Liability line inside a startup package.
Which is cheapest?
None of the four publishes flat pricing. Corgi quotes founders self-serve; Testudo provides an indication in days via its AI Risk Engine; Armilla prices through brokers alongside its assessment; and AIUC ties price to how safe a system is shown to be under AIUC-1. Compare quotes for the same limits and coverage.

The bottom line
Corgi and its alternatives agree that AI creates real, insurable risk — they just package it differently. Corgi is breadth: a full-stack, AI-native carrier that bundles AI into modular startup insurance and binds the same day. Testudo is depth on one problem: a standalone, Lloyd's-backed generative AI liability policy up to $10M. Armilla adds an independent verification practice on top of affirmative coverage for generative AI and agents, distributed through brokers. AIUC leads with a certification standard and audits, then insures the certified result for enterprises. Match the choice to whether you need a startup stack or dedicated AI coverage, the shape of that coverage, and how you want to buy — none of them publishes flat pricing, so compare quotes for the same limits.
