# Harper vs StartupInsurance.ai Builders Risk Insurance

Harper quotes builders risk for trades with same-day certificates; StartupInsurance.ai lists it for hardware founders off the self-serve form.

## Research Scope and Use

Use this comparison to evaluate Harper and StartupInsurance.ai for Builders Risk Insurance 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

Harper places builders risk inside Construction & Contractors coverage and issues additional-insured certificates the same day. StartupInsurance.ai catalogues the line for hardware-adjacent startups and discusses it with a specialist rather than the public quote checkboxes.

## What Is Builders Risk Insurance?

Builders risk insurance addresses physical property losses during building construction. [10](https://content.naic.org/glossary-insurance-terms "Glossary of Insurance Terms")

## Key Differences in Builders Risk Insurance

### Trades Placement Versus Hardware Catalogue

Harper and StartupInsurance.ai both arrange builders risk without underwriting it. Harper’s Construction & Contractors page is written for GCs, specialty trades, remodelers, handymen, residential and commercial builders, and construction managers. StartupInsurance.ai lists Builders Risk among physical-risk lines for founders building robots, hardware, energy or defense tech. [3](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance") [7](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") [8](https://www.contractornerd.com/terms-and-conditions/ "Terms and Conditions")

### Certificates Versus an Ask-a-Specialist Path

Harper says one application is quoted across construction markets and that certificates with additional-insured, waiver and primary-and-non-contributory wording go out the same day. StartupInsurance.ai’s physical-risk section uses “Ask about your insurance requirements,” and Builders Risk is not a checkbox on the public quote-application screen. [3](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance") [7](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") [6](https://quotes.startupinsurance.ai/ "Apply for Startup Insurance | StartupInsurance.ai")

### What Is Described About the Policy

Harper describes covering the structure, materials and fixtures from ground break to handover. StartupInsurance.ai’s reviewed pages name the line but do not describe project types, coverage period or specific policy terms. [3](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance") [7](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review")

## What to Confirm in Builders Risk Insurance Quotes

- Ask StartupInsurance.ai which carrier would issue the policy and whether Harper’s admitted or excess-and-surplus path would apply to a hardware fit-out. [7](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") [3](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance")
- Confirm certificate needs if lenders or GCs require additional-insured wording; Harper describes same-day issuance, StartupInsurance.ai’s reviewed pages do not. [3](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance") [7](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review")
- Get limits from both; neither publishes sample project-value figures. [3](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance") [7](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review")
- Match ground-break-to-handover wording on Harper’s quote to whatever form StartupInsurance.ai places. [3](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance") [7](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review")

## Offering Details

| Criteria | Harper Builders Risk Coverage | StartupInsurance.ai Builders Risk Insurance |
| --- | --- | --- |
| Role in This Line | Harper places builders risk as one piece of its Construction & Contractors insurance package, describing itself as calling every market that writes construction and presenting the options back, rather than underwriting the coverage itself. [3](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance") (Evidence: Company-reported; scope: Construction & Contractors industry page; describes Harper's placement role for the package that includes builders risk, not a standalone builders risk product page..) | 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. [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 builders-risk-specific placement terms..) |
| Issuing Insurer | The reviewed pages do not name the insurer or insurers that would issue a builders risk policy Harper places; the industry page refers only to 'every market that writes construction' without listing carriers. [3](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance") (Evidence: Not publicly disclosed; scope: Checked the Construction & Contractors industry page and homepage industries carousel on 2026-09-23; a specific insurer would appear on the quote or policy..) | 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. [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 insurer for a builders risk placement is not disclosed on the pages reviewed and varies by placement..) |
| Who It’s For | Harper says Construction & Contractors coverage, including builders risk, is for general contractors managing subs, specialty trades such as roofing, framing, electrical, plumbing and HVAC, remodelers and handymen, residential and commercial builders, and construction managers. [3](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance") (Evidence: Company-reported; scope: Construction & Contractors industry page 'Who this is for' section; not builders-risk-specific eligibility criteria such as project value or completion timeline..) | 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. [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 | Harper describes builders risk as covering the structure, materials and fixtures of a project from ground break to handover, alongside jobsite liability and the certificates a project requires to start. [3](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance") [4](https://www.harperinsure.com/ "Harper Homepage") (Evidence: Company-reported; scope: Construction & Contractors industry page coverage callouts and homepage industries carousel; the issued policy and declarations would control actual terms..) | 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. [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 project types, coverage period, or specific policy terms..) |
| Limits and Retentions | Harper's reviewed pages do not publish builders risk limits, deductibles or maximum project values; the industry page says cost depends on trade, payroll and revenue and is quoted individually across multiple markets. [3](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance") (Evidence: Not publicly disclosed; scope: Construction & Contractors industry page FAQ 'What does it cost?'; no published limit or retention figures found..) | The reviewed pages do not publish sample builders risk project-value limits, covered perils, or policy-period terms. [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; limits would only surface on an actual quote..) |
| Risk Services | Harper says it writes certificates of insurance with additional-insured, waiver-of-subrogation and primary-and-non-contributory wording the same day a contract calls for it, and checks subcontractors' certificates so their risk does not become the general contractor's. [3](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance") (Evidence: Company-reported; scope: Construction & Contractors industry page; describes the certificate and risk-review service Harper says it provides around construction projects, which includes builders risk jobs..) | Not described in the reviewed sources. |
| How to Apply | Harper says it takes one application for construction risk, including builders risk, and quotes it across every market it says writes construction, admitted where pricing allows and excess-and-surplus lines when the work demands it. [3](https://www.harperinsure.com/industries/construction-insurance "Construction & Contractors Insurance") (Evidence: Company-reported; scope: Construction & Contractors industry page 'Why Harper' section; specific markets contacted for a given project are not named..) | 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. [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); 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..) |
