A listing may be arranged through an insurer or partner. “Not listed” means this catalogue has no separate offering recorded; ask the provider whether it can quote the coverage and request the policy terms.



## Optional Spot Service Handoff

Spot can help prepare applications, coordinate brokers, and compare proposals. If that work is needed, collect the company's task, known deadline, current broker, and open questions for a [free consultation](https://spot.insure/pricing.md). The company decides what to buy; Spot does not automatically bind coverage.

## Where the Buying Paths Differ

Heffernan Insurance Brokers describes its route this way: Technology buyers work with a specialist broker who gathers insurer quotes and helps choose coverage; Heffernan does not promise a universal quote or binding time for growth-stage programs. Quick Insure is a separate path for selected personal and short-term business products. [7](https://www.heffins.com/business-insurance/technology/ "Technology Company Insurance") [9](https://www.heffins.com/business-insurance/cyber-insurance/ "Cyber Security Insurance") Marsh McLennan Agency describes its route this way: MMA lists general liability, commercial property, workers’ compensation, professional liability, commercial auto, and cyber liability for small businesses, and invites buyers to call for a personalized quote. It does not describe an online purchase or binding route. [41](https://www.marshmma.com/us/solutions/small-business.html "Small Business Insurance Solutions") The useful distinction is where the first submission goes and who continues with the account. Ask who gathers information, who can bind, which legal producer appears on the proposal, and who remains your day-to-day contact; a quote request alone does not establish an issued policy.

## Customer Fit and Published Product Menus

Heffernan Insurance Brokers lists its business focus as Independent brokerage for businesses from small companies to scaling technology firms, with named industry practices [1](https://www.heffins.com/ "Heffernan Insurance Brokers") [7](https://www.heffins.com/business-insurance/technology/ "Technology Company Insurance") [8](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance") Marsh McLennan Agency lists its business focus as Business insurance and employee health and benefits, with retirement, wealth, and private-client services also listed for the United States and Canada. [28](https://www.marshmma.com/us/mma/about-us.html "Who We Are") Match those stated audiences to your operations, locations, contracts, and loss history, then ask which practice or team would service the account. A stated focus is not an eligibility decision.

The published catalogs list Heffernan Insurance Brokers lines not listed by Marsh McLennan Agency: business owner’s policy, employee health benefits, fidelity bonds; Marsh McLennan Agency lines not listed by Heffernan Insurance Brokers: intellectual property, media. These differences do not establish that either company excludes a line or will quote your risk. [8](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance") [11](https://www.heffins.com/employee-benefits/ "Health Insurance services") [19](https://www.heffins.com/business-insurance/health-care/homecare/ "Home Care Business Insurance") [15](https://www.heffins.com/business-insurance/construction/ "Construction & Contractor Liability Insurance") [33](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability") [38](https://www.marshmma.com/us/solutions/property.html "Property Insurance")

Both providers list builders risk, cargo transit, commercial auto, commercial property, crime, cyber, directors and officers, employment practices, fiduciary, general liability, kidnap ransom, professional E&O, surety bonds, workers’ compensation. Treat that overlap as a shortlist for a side-by-side proposal review, not proof of matching policy language. For each line, compare the named insurer, insured entities, limits, deductibles or retentions, exclusions, endorsements, retroactive dates where relevant, and state-specific terms. [15](https://www.heffins.com/business-insurance/construction/ "Construction & Contractor Liability Insurance") [16](https://www.heffins.com/business-insurance/marine-cargo/ "Marine Cargo") [38](https://www.marshmma.com/us/solutions/property.html "Property Insurance") [35](https://www.marshmma.com/us/solutions/international.html "International")

## Service and Quote Questions

For Heffernan Insurance Brokers, published service information says: Heffernan says clients receive claims, loss-control, HR and risk-management support, with digital access to documents and certificates; confirm which tools and services your engagement includes. [6](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage") [23](https://www.heffins.com/about-us/modern-brokerage-solutions/ "Modern Brokerage Solutions") For Marsh McLennan Agency, it says: MMA says the Marsh Agency brand transition will not change clients’ account manager, team, or point of contact, and will not affect existing policies or programs; clients may see the legal-name change during renewals. This describes the rebrand transition, not MMA’s general renewal process. [39](https://www.marshmma.com/us/mma/rebranding-to-marsh-agency.html "Rebranding to Marsh Agency") Before binding, agree on routine endorsement requests, certificates, renewal timing, claim-notice instructions, and any fee or commission disclosure that applies to your account. Claims assistance or a service portal does not determine whether a loss is covered.

For a useful quote comparison, request the same limits and relevant endorsements from both sides, then check the full forms and itemized premium, fees, taxes, and financing charges. Confirm any account-specific unknowns with the producer and insurer named on the proposal.

Technology-page FAQ “how do I get” language is educational process copy, not a measured SLA.; verified: 2026-09-16.) | MMA’s US small-business page lists general liability, commercial property, workers’ compensation, professional liability, commercial auto, and cyber liability, and invites buyers to call 833-256-4266 for a personalized quote. The page also contains a small-business specialist form, but its function and any online application, purchase, or binding route are not established by the page reviewed.

The phone invitation does not establish quote speed, eligibility, online purchase or binding; the embedded specialist form's function was not established.; verified: 2026-09-29.) |
| Servicing and renewals | Heffernan says clients receive claims, loss-control, HR and risk-management support, with digital access to documents and certificates; confirm which tools and services your engagement includes.

This describes the rebrand transition, not MMA’s general renewal process. [39](https://www.marshmma.com/us/mma/rebranding-to-marsh-agency.html "Rebranding to Marsh Agency") (Evidence: Company-reported; scope: Only the announced Marsh Agency rebrand and its stated effect on existing clients; this does not document MMA’s general renewal workflow, renewal service level, or policy terms.; verified: 2026-09-28.)<br><br>MMA’s Tampa office page lists InsurLink for policy and endorsement access, CSR24 for certificates, carrier contact information for commercial and personal-lines claims, and a local-consultant contact route. [43](https://www.marshmma.com/us/locations/florida/tampa.html "Tampa, Florida") (Evidence: Company-reported; scope: Services and client tools listed on the Tampa, Florida office page only. The claims listing provides carrier contact information and does not establish that MMA adjusts claims.; verified: 2026-09-28.) |
| Claims assistance | Heffernan describes claims consulting from intake through resolution, including carrier liaison and medical triage; its marine-cargo program separately claims authority to adjust, settle and pay. These are service claims, not a promise that your loss is covered. [10](https://www.heffins.com/business-insurance/claims-advocacy/ "Claims Advocacy") [16](https://www.heffins.com/business-insurance/marine-cargo/ "Marine Cargo") (Evidence: Company-reported; scope: Company descriptions of advocacy and a specialty cargo claims unit. Speed, “$1 billion managed,” and “up to 75% faster” figures are not adopted as verified performance.; verified: 2026-09-16.) | On its business-interruption page, MMA says it will advocate with insurers for clients if complex claim issues arise. This is a company-reported service statement; it does not establish claim outcomes or an adjusting/payment role. [29](https://www.marshmma.com/us/solutions/business-interruption-insurance.html "Business Interruption Insurance") (Evidence: Company-reported; scope: Company-described support for complex claims in the business-income and contingent-business-interruption page context; not a promise of claim outcomes or evidence that MMA adjusts or pays claims.; verified: 2026-09-28.) |
