# Chubb vs StartupInsurance.ai Surety Bonds

Chubb underwrites named construction, commercial, transactional and international bonds; StartupInsurance.ai lists Surety as a physical-risk line for hardware founders.

## Research Scope and Use

Use this comparison to evaluate Chubb and StartupInsurance.ai for Surety Bonds against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote.

## Summary

Chubb issues surety bonds and names construction, commercial, transactional and international products. StartupInsurance.ai catalogues Surety for robot, hardware, energy and defense startups and routes it to a specialist, not its self-serve quote form.

## What Is Chubb?

Chubb is the marketing name for a global insurance group whose U.S. companies underwrite commercial property, casualty, cyber and financial-lines coverage, including technology-focused DigiTech ERM and small-business packages. Founders and finance teams typically work through an appointed agent, then receive a policy issued by a named Chubb-group insurer rather than by the Swiss holding company.

## What Are Surety Bonds?

A surety bond is a three-party agreement: a surety guarantees an obligation your business (the principal) owes to a customer or other party (the obligee) if your business defaults. It isn't insurance that pays your business for its own losses. [10](https://content.naic.org/glossary-insurance-terms "Glossary of Insurance Terms") [11](https://www.sba.gov/funding-programs/surety-bonds "Surety bonds")

## Key Differences in Surety Bonds

### Named Bond Products Versus a Catalogue Word

Chubb underwrites surety and lists construction, commercial, transactional and international bond families. StartupInsurance.ai lists “Surety” among physical-risk lines on the homepage and does not name license, permit, performance or payment bonds. [4](https://www.chubb.com/us-en/surety.html "Surety Bonds") [7](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review")

ContractorNerd Insurance Services, LLC, the agency behind StartupInsurance.ai, arranges placement and does not underwrite. Chubb is the surety on Chubb bonds. StartupInsurance.ai’s homepage carrier panel names six insurers at program level, including Chubb, but does not say which, if any, issues a given surety bond. [4](https://www.chubb.com/us-en/surety.html "Surety Bonds") [7](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") [8](https://www.contractornerd.com/terms-and-conditions/ "Terms and Conditions")

### Who the Offering Is Built For

Chubb positions commercial surety for highly rated public and private companies and transactional surety for small or infrequent needs. StartupInsurance.ai frames the physical-risk block, including Surety, around founders building robots, hardware, energy or defense tech. [4](https://www.chubb.com/us-en/surety.html "Surety Bonds") [7](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review")

### How You Ask for a Bond

Chubb offers Surety Marketplace for transactional bonds and agents or brokers for other products. StartupInsurance.ai’s physical-risk call to action is to ask about insurance requirements with a specialist; Surety is not a checkbox on the public quote-application coverage screen (D&O, cyber, tech E&O, EPL, fiduciary, crime, GL). [4](https://www.chubb.com/us-en/surety.html "Surety Bonds") [7](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") [6](https://quotes.startupinsurance.ai/ "Apply for Startup Insurance | StartupInsurance.ai")

Neither StartupInsurance.ai’s reviewed pages nor Chubb’s transactional description publish sample penal sums for a hardware founder’s typical obligee. Chubb does publish a company-wide T-listing figure; StartupInsurance.ai’s reviewed pages do not publish bond amounts or rates. [4](https://www.chubb.com/us-en/surety.html "Surety Bonds") [7](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review")

## What to Confirm in Surety Bonds Quotes

- Ask StartupInsurance.ai which bond type and surety company it would place; do not assume the homepage Chubb logo means a Chubb surety bond. [4](https://www.chubb.com/us-en/surety.html "Surety Bonds") [7](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review")
- If you need construction performance or payment wording, confirm StartupInsurance.ai can place it; Chubb lists those forms. [4](https://www.chubb.com/us-en/surety.html "Surety Bonds") [7](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review")
- Ask whether the bond is quoted only with a specialist, since it is absent from StartupInsurance.ai’s self-serve coverage checkboxes. [6](https://quotes.startupinsurance.ai/ "Apply for Startup Insurance | StartupInsurance.ai")
- Confirm indemnity, penal sum and obligee name on both a Chubb form and any StartupInsurance.ai placement. [4](https://www.chubb.com/us-en/surety.html "Surety Bonds") [7](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review")

## Offering Details

| Criteria | Chubb Surety Bonds | StartupInsurance.ai Surety Bonds |
| --- | --- | --- |
| Role in This Line | Chubb underwrites surety bonds directly and says it has written bonds for more than 140 years, describing itself as the 5th largest surety provider in the U.S. [4](https://www.chubb.com/us-en/surety.html "Surety Bonds") (Evidence: Company-reported; scope: Surety Bonds product page introduction; company-reported ranking, not independently verified..) | StartupInsurance.ai does not underwrite or issue surety bonds itself. ContractorNerd Insurance Services, LLC, the licensed property and casualty agency behind the brand, is licensed in all 50 states and arranges placement; its terms describe the company as an insurance agency/producer that does not underwrite insurance. Surety bonds are typically issued by a surety company rather than an insurer in the conventional sense, and the reviewed pages do not distinguish the two. [8](https://www.contractornerd.com/terms-and-conditions/ "Terms and Conditions") [9](https://www.contractornerd.com/insurance-licenses/ "Insurance Licenses") [7](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") (Evidence: Company-reported; scope: ContractorNerd's terms and conditions and insurance-licenses page; describes the brokerage's general role, not surety-specific placement terms or which entity type ultimately issues a bond..) |
| Issuing Insurer | Not described in the reviewed sources. | The homepage's carrier panel names six insurers at the program level (The Hartford, Chubb, Coalition, Tokio Marine HCC, Travelers and CNA) but does not state which one, if any, issues a given company's surety bond. [7](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") (Evidence: Not publicly disclosed; scope: Carrier panel is program-wide rather than broken out by line; the surety company behind a bond is not disclosed on the pages reviewed and varies by placement..) |
| Who It’s For | Chubb positions Commercial Surety Bonds for highly rated public and private companies, while Transactional Surety Bonds target commercial businesses and individuals with small or infrequent surety needs. [4](https://www.chubb.com/us-en/surety.html "Surety Bonds") (Evidence: Company-reported; scope: Products & Services list..) | The section frames these seven lines around founders "building robots, hardware, energy or defense tech," saying StartupInsurance.ai treats them as "our daily lines, not our exceptions" — positioning surety bonds as something it arranges regularly for hardware-adjacent startups, rather than as a rare add-on. [7](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") (Evidence: Company-reported; scope: Same homepage section; describes the target customer segment StartupInsurance.ai says it serves for this catalogue of lines, not formal underwriting eligibility criteria..) |
| Coverage Features | Chubb's surety products span Construction Surety Bonds (performance, payment, maintenance, supply and install, service bonds), Commercial Surety Bonds (license and permit, court, commercial contract, reclamation, customs and workers' compensation bonds) for highly rated public and private companies, Transactional Surety Bonds for smaller or infrequent needs, and International Surety Bonds. [4](https://www.chubb.com/us-en/surety.html "Surety Bonds") (Evidence: Company-reported; scope: Products & Services list; subject to underwriting..) | StartupInsurance.ai lists "Surety" among seven lines in the homepage's "Physical risk, because AI outgrew software" section — Products Liability, Inland Marine, Tools and Equipment, Commercial Auto, Builders Risk, Surety and Property — offered alongside the core startup program of GL, cyber, D&O and related lines. The page uses the word "Surety" rather than "surety bonds," and does not name a bond type. [7](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") (Evidence: Company-reported; scope: Homepage "Physical risk, because AI outgrew software" section as read on 2026-09-23; the reviewed page names the line but does not describe bond types (e.g. license, permit, performance), bond amounts, or underwriting terms..) |
| Limits and Retentions | Chubb reports a $2.289 billion aggregate Treasury (T-listing) as of August 2026, and says it has surety capabilities in more than 45 countries and territories. [4](https://www.chubb.com/us-en/surety.html "Surety Bonds") (Evidence: Company-reported; scope: Surety Bonds product page introduction stats..) | The reviewed pages do not publish sample bond amounts, bond types, or premium rates for surety bonds. [7](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") [6](https://quotes.startupinsurance.ai/ "Apply for Startup Insurance | StartupInsurance.ai") (Evidence: Not found in reviewed sources; scope: Homepage and quote-intake screen as read on 2026-09-23; bond amounts would only surface on an actual application..) |
| How to Apply | Chubb offers Chubb Surety Marketplace, an online platform for Transactional Surety Bonds, in addition to placement through appointed agents and brokers for its other surety products. [4](https://www.chubb.com/us-en/surety.html "Surety Bonds") (Evidence: Company-reported; scope: Transactional Surety Bonds description..) | The physical-risk section's call to action reads "Ask about your insurance requirements →" rather than the "Get Quotes" button used elsewhere on the homepage, indicating surety bonds are discussed with a specialist rather than quoted through a self-serve form. [7](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") (Evidence: Company-reported; scope: Homepage "Physical risk, because AI outgrew software" section as read on 2026-09-23; the page does not describe what that conversation covers..)<br><br>The public quote-application's coverage-selection screen offers seven checkboxes (D&O, Cyber, Tech E&O, EPL, Fiduciary, Crime and GL); Surety is not one of them, so it is not part of that self-serve intake flow. [6](https://quotes.startupinsurance.ai/ "Apply for Startup Insurance | StartupInsurance.ai") (Evidence: Not found in reviewed sources; scope: Initial coverage-selection screen of the quote application as read on 2026-09-23; a later screen or specialist conversation could still address this line..) |
| Claims Support | Chubb publishes instructions for submitting a surety claim by email or mail and offers a dedicated email and phone line to verify the authenticity of a Chubb surety bond. [4](https://www.chubb.com/us-en/surety.html "Surety Bonds") (Evidence: Company-reported; scope: Surety Claims Resources section and FAQ..) | Not described in the reviewed sources. |
