StartupInsurance.ai vs THREE by Berkshire Hathaway: How Do They Compare for Inland Marine Insurance?

StartupInsurance.ai does not underwrite inland marine 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. ^4,5,2Company-reported. ContractorNerd's terms and conditions and insurance-licenses page; describes the brokerage's general role, not inland-marine-specific placement terms.

THREE presents Inland Marine as a component of its combined Business Owners Policy rather than identifying it as a separate standalone policy on the reviewed product page. ⁸Company-reported. Company-described U.S. package structure. The page does not establish underwriting terms or that every listed category will be included for every applicant.

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 inland marine policy. ²Not publicly disclosed. Carrier panel is program-wide rather than broken out by line; the insurer for an inland marine placement is not disclosed on the pages reviewed and varies by placement.

The linked sample policy's declarations identify Berkshire Hathaway Direct Insurance Company as issuer. ⁷Company-reported. This is the issuer named on the public sample only; the sample does not establish the issuing entity for every state-specific quote or buyer's issued policy.

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 inland marine as a line it places regularly for hardware-adjacent startups moving equipment between sites, rather than as a rare add-on. ²Company-reported. Same homepage section; describes the target customer segment StartupInsurance.ai says it serves for this catalogue of lines, not formal underwriting eligibility criteria.

The reviewed product page does not state separate eligibility rules for Inland Marine; the general quote and advisor route is not proof that a particular business qualifies for it. ^8,6Not publicly disclosed. Eligibility and state availability remain unestablished for an individual risk until THREE returns its quote and applicable forms.

StartupInsurance.ai lists Inland Marine 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 section lists Inland Marine and "Tools and Equipment" separately, suggesting the two are treated as distinct offerings on this page. ²Company-reported. Homepage "Physical risk, because AI outgrew software" section as read on 2026-09-23; the reviewed page names the line but does not describe specific coverage terms, forms or exclusions, and does not explain how it distinguishes inland marine from the adjacent tools-and-equipment listing.

THREE's Business Owners Policy page lists Inland Marine among its marketed coverage categories in the combined policy. This describes the product page, not whether the category appears in a particular quote or responds to a loss. ^8,7Company-reported. Official THREE package marketing for Inland Marine. The sample policy is state-selectable and does not establish that this item is included in every quote or issued policy.

The reviewed pages do not publish sample inland marine limits, scheduled-equipment values or deductibles. ^2,3Not found in reviewed sources. Homepage and quote-intake screen as read on 2026-09-23; limits would only surface on an actual quote.

The reviewed public product page does not state a separate limit or deductible for Inland Marine; THREE says the quote-specific insurance summary lists limits and deductibles. ^8,7Not publicly disclosed. No number is inferred from the sample policy. The quote and issued declarations control the buyer-specific limit and deductible.

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 inland marine is discussed with a specialist rather than quoted through a self-serve form. ²Company-reported. Homepage "Physical risk, because AI outgrew software" section as read on 2026-09-23; the page does not describe what that conversation covers.

The public quote-application's coverage-selection screen offers seven checkboxes (D&O, Cyber, Tech E&O, EPL, Fiduciary, Crime and GL); Inland Marine is not one of them, so it is not part of that self-serve intake flow. ³Not found in reviewed sources. 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.

THREE directs small-business prospects to an online quote and says licensed Small Business Advisors can help with the process. ⁶Company-reported. This is the route for the overall THREE product. It does not show whether Inland Marine will be offered for a particular business or whether a customer can bind that line without an issued policy.
