It identifies differences and questions to confirm; it does not select a winner for a particular business.

[3](https://www.markel.com/us/industries/construction/large-builders-risk "Builders Risk Insurance") [5](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review")

## Markel Insurance: Specialty Business and Products

Markel Insurance is Markel Group's specialty and small-business insurance business, with offerings across packages, workers' compensation, cyber, professional and management liability, property, marine, and surety.

## What Is StartupInsurance.ai?

StartupInsurance.ai fits startups, including hardware, robotics and AI companies, that must meet a customer-contract or investor insurance requirement and want a free policy review it says takes 48 hours. Look elsewhere if you need a named AI-failure insurer or a documented claims advocate before you buy.

## 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

### Project Audience and Scope

StartupInsurance.ai lists builders risk among physical-risk lines for founders building robotics, hardware, energy or defense technology, framing the line around startup projects. Markel describes projects from basic structures to complex infrastructure and power work, naming civil engineering, bridges, dams and tunnels. A startup constructing a facility or hardware build-out can ask StartupInsurance.ai how it handles the specific project; larger civil works can be tested against Markel’s listed project examples. [5](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") [3](https://www.markel.com/us/industries/construction/large-builders-risk "Builders Risk Insurance")

### Specialist Discussion or Capacity Proposal

StartupInsurance.ai’s physical-risk section invites buyers to ask about insurance requirements, while its public self-serve application does not include builders risk among the coverage checkboxes. Markel describes possible full or subscriber participation and periods up to 60 months. Buyers needing a defined capacity proposal should ask Markel for the project limit and share; founders contacting StartupInsurance.ai should ask which placement markets can quote the build. [6](https://quotes.startupinsurance.ai/ "Apply for Startup Insurance | StartupInsurance.ai") [3](https://www.markel.com/us/industries/construction/large-builders-risk "Builders Risk Insurance")

### Insurer Identification

StartupInsurance.ai names several insurers at the broader program level but does not identify which one would issue a builders-risk policy. Markel’s record describes its own offering and participation capability, though the project-specific insurer and share still need confirmation. Ask each provider to identify every proposed carrier and its role before comparing forms, limits or price. [5](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") [3](https://www.markel.com/us/industries/construction/large-builders-risk "Builders Risk Insurance")

## What to Confirm in Builders Risk Insurance Quotes

- Ask StartupInsurance.ai which carrier can quote the project, what application details it needs, and whether there is a dedicated builders-risk intake. [6](https://quotes.startupinsurance.ai/ "Apply for Startup Insurance | StartupInsurance.ai")
- Ask Markel for the actual project period, limit and whether its participation is full or shared. [3](https://www.markel.com/us/industries/construction/large-builders-risk "Builders Risk Insurance")
- Give both teams the project location, construction type, total values and completion schedule; request the proposed policy forms and deductibles. [5](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") [3](https://www.markel.com/us/industries/construction/large-builders-risk "Builders Risk Insurance")

## Offering Details

| Criteria | Markel builders risk | StartupInsurance.ai Builders Risk Insurance |
| --- | --- | --- |
| Role in This Line | Markel offers builders-risk coverage for construction projects from basic four-wall risks to complex infrastructure and power projects. [3](https://www.markel.com/us/industries/construction/large-builders-risk "Builders Risk Insurance") (Evidence: Company-reported; scope: Large builders-risk page; specific project underwriting applies..) | 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 | Targeted exposures include civil engineering, mechanical engineering and completed civil engineering projects, including bridges, dams, tunnels and power facilities. [3](https://www.markel.com/us/industries/construction/large-builders-risk "Builders Risk Insurance") (Evidence: Company-reported; scope: Published target examples; no eligibility guarantee..) | 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 | Confirm in your quote. | 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 | Markel states coverage periods may extend up to 60 months and that it may write 100% or participate as a subscriber; project-specific capacity must be confirmed. [3](https://www.markel.com/us/industries/construction/large-builders-risk "Builders Risk Insurance") (Evidence: Company-reported; scope: Program capability, not a commitment for an individual risk..) | 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 | Confirm in your quote. | 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..) |
