## What Is Builders Risk Insurance?

Builders risk protects the project you are building, including materials meant for it, against physical loss until construction ends. The gaps that cost owners money are materials in storage or transit, the existing building in a renovation, and coverage ending when you occupy early. [9](https://content.naic.org/glossary-insurance-terms "Glossary of Insurance Terms") [10](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [11](https://assets.touchpointmarkets.com/e8/58/dec27c1b462c8227b4693fb8ac81/ih-00-70-05-17-builders-risk-coverage-form.pdf "Builders Risk Coverage Form") [12](https://go.usassure.com/rs/381-ISO-510/images/us-assure-builders-risk-application-tip-sheet.pdf "Builders Risk Application Tip Sheet")

## Key Differences in Builders Risk Insurance

### Intended Project and Buyer

StartupInsurance.ai places builders risk in a physical-risk catalogue aimed at founders building robotics, hardware, energy, or defense technology. Marsh McLennan Agency describes a Builders’ Risk Panel for projects under construction or renovation, without similarly narrowing its overview to startup or hardware businesses. A founder building a facility or prototype should ask StartupInsurance.ai whether the project fits its physical-risk program and ask MMA how its construction panel handles specialized equipment and materials. [5](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") [3](https://www.marshmma.com/us/industries/construction.html "Construction Insurance | MMA")

### Access to Placement

StartupInsurance.ai directs buyers of these physical-risk lines to ask about insurance requirements, while its homepage uses a separate Get Quotes path elsewhere. Marsh McLennan Agency invites a buyer to contact an adviser or specialist to discuss placement. Neither description promises a quote or binding timeline, so teams with a construction start date should ask both for the information needed to assess the project and the expected response schedule. [5](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") [3](https://www.marshmma.com/us/industries/construction.html "Construction Insurance | MMA")

## What to Confirm in Builders Risk Insurance Quotes

- Ask StartupInsurance.ai whether the project is treated as builders risk, equipment coverage, or both, especially for prototype hardware on site. [5](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review")
- Ask Marsh McLennan Agency which panel insurer and form would address specialized equipment, materials, and testing during construction. [3](https://www.marshmma.com/us/industries/construction.html "Construction Insurance | MMA")
- Confirm project eligibility, start-date requirements, and who can bind coverage before work begins. [5](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review")

## Offering Details

| Criteria | Marsh McLennan Agency builders risk (official overview) | StartupInsurance.ai Builders Risk Insurance |
| --- | --- | --- |
| Role in This Line | Marsh McLennan Agency describes arranging builders risk for the audience stated on the cited product page. [3](https://www.marshmma.com/us/industries/construction.html "Construction Insurance | MMA") (Evidence: Company-reported; scope: builders risk marketed by marsh-mclennan-agency; scope is limited to the cited official product overview and described audience. This is not a policy form or a universal eligibility statement..) | StartupInsurance.ai does not underwrite builders risk coverage 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. [7](https://www.contractornerd.com/terms-and-conditions/ "Terms and Conditions") [8](https://www.contractornerd.com/insurance-licenses/ "Insurance Licenses") [5](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 builders-risk-specific placement terms..) |
| Issuing Insurer | Confirm in your quote. | 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, underwrites a given company's builders risk policy. [5](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 insurer for a builders risk placement is not disclosed on the pages reviewed and varies by placement..) |
| Who It’s For | Construction projects and clients described on the construction page; individual project eligibility is placement-specific. [3](https://www.marshmma.com/us/industries/construction.html "Construction Insurance | MMA") (Evidence: Company-reported; scope: builders risk marketed by marsh-mclennan-agency; scope is limited to the cited official product overview and described audience. This is not a policy form or a universal eligibility statement..) | 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 builders risk as a line it places regularly for hardware-adjacent startups with a construction or build-out project, rather than as a rare add-on. [5](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 | The cited product page describes a Builders' Risk Panel for projects under construction or renovation, with example risks including fire, theft, vandalism, and natural disasters. Marketing description only; actual coverage, exclusions, conditions, limits, and availability depend on the issued policy and jurisdiction. [3](https://www.marshmma.com/us/industries/construction.html "Construction Insurance | MMA") (Evidence: Company-reported; scope: builders risk marketed by marsh-mclennan-agency; scope is limited to the cited official product overview and described audience. This is not a policy form or a universal eligibility statement..) | StartupInsurance.ai lists Builders Risk 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. [5](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 project types, coverage period, or specific policy terms..) |
| Limits and Retentions | The cited overview does not set a universal limit or retention for this line. Ask for the proposed policy form, limits, retentions, exclusions, and conditions in the quote. [3](https://www.marshmma.com/us/industries/construction.html "Construction Insurance | MMA") (Evidence: Not publicly disclosed; scope: Only the cited marketing page was reviewed for published limit and retention information; no policy-form entitlement is inferred..) | The reviewed pages do not publish sample builders risk project-value limits, covered perils, or policy-period terms. [5](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; limits would only surface on an actual quote..) |
| How to Apply | The page invites organizations to contact a Marsh McLennan Agency adviser or specialist to discuss placement. The page does not establish a quote, bind, or coverage-effective timeline. [3](https://www.marshmma.com/us/industries/construction.html "Construction Insurance | MMA") (Evidence: Company-reported; scope: builders risk marketed by marsh-mclennan-agency; scope is limited to the cited official product overview and described audience. This is not a policy form or a universal eligibility statement..) | 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 builders risk is discussed with a specialist rather than quoted through a self-serve form. [5](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); Builders Risk 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..) |
