StartupInsurance.ai lists surety for robot, hardware, energy and defense startups without naming bond types; Chubb publishes four surety categories. ## Chubb vs StartupInsurance.ai Surety Bonds Summary Chubb publishes detailed construction, commercial, transactional and international surety lines; StartupInsurance.ai names surety for robot, hardware, energy and defense startups but gives no bond types. [1](https://www.chubb.com/us-en/surety.html "Surety Bonds") [2](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") [4](https://www.contractornerd.com/terms-and-conditions/ "Terms and Conditions") [5](https://www.contractornerd.com/insurance-licenses/ "Insurance Licenses") ## What Are the Key Differences Between Chubb and StartupInsurance.ai Surety Bonds? ### Named Bond Types Versus Startup Catalogue Listing Chubb lists construction, commercial, transactional and international bonds, including performance, payment, license and permit types. StartupInsurance.ai lists “Surety” among physical-risk lines for robot, hardware, energy and defense startups but does not specify license, permit, performance or payment bonds. [1](https://www.chubb.com/us-en/surety.html "Surety Bonds") [2](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") Choose Chubb if you already know you need construction, license or transactional surety; choose StartupInsurance.ai if you are a hardware or deep-tech startup and need a broker to clarify which bond fits. ### 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. [1](https://www.chubb.com/us-en/surety.html "Surety Bonds") [2](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).

Chubb does publish a company-wide T-listing figure; StartupInsurance.ai’s reviewed pages do not publish bond amounts or rates. [1](https://www.chubb.com/us-en/surety.html "Surety Bonds") [2](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") ## What Should You Confirm in Chubb and StartupInsurance.ai 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. [1](https://www.chubb.com/us-en/surety.html "Surety Bonds") [2](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. [1](https://www.chubb.com/us-en/surety.html "Surety Bonds") [2](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. [3](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.

[1](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. [2](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..) | | 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. [1](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. [2](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..) | | 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. [1](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. [2](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..) | | 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. [1](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.
