Platform Insurance: Underwriting Shared Risk

Purpose-built cover for two-sided marketplaces and operator networks. Protect the platform, the people transacting on it, and every stage of growth from first cheque to listing.

The platform problem: everyone names you

When a transaction goes wrong on a marketplace, the operator is rarely left out of it. Buyers, sellers, providers, brands and regulators all reach for the platform. You need a policy shaped like the way those claims actually arrive.

Peer-to-peer liability

Cover for bodily-injury and property-damage claims that trace back to a transaction your platform arranged.

Vetting & moderation failures

Allegations aimed at how you screen, verify, onboard or moderate the supply side of your network.

Service reliability

Claims tied to outages, ranking shifts, listing errors, payout delays and other product failures your users feel.

The moments that trigger exposure

The enterprise supplier review

Large accounts will not join until you are named as an Additional Insured and carry limits above their procurement floor.

The trust & safety incident

One high-visibility failure drives churn, press coverage and third-party demands within the same fortnight.

The supply-side growth curve

As you scale contractors, worker-classification and employment-related allegations become routine rather than rare.

Claims that follow management decisions and corporate governance.

How these claims actually arrive

The “careless referral”

A provider damages a home during a booked job. The buyer names the platform too, alleging the vetting process was never real.

The automated suspension

Your moderation model wrongly flags and bans a high-volume seller. They file for lost income and reputational harm.

The classification suit

A group of contractors alleges misclassification and seeks back pay, damages and benefits across three states.

FAQ

What insurance does a marketplace startup actually need?
Most operators start with Technology Errors & Omissions for product-performance claims, Cyber for user-data exposure, General Liability for bodily injury and property damage tied to transactions, and Directors & Officers. With Halden, platforms that facilitate payments should also weigh Crime and Fidelity cover for transaction fraud.
What does trust-and-safety cover include?
It responds to allegations about screening, verification, onboarding and moderation decisions, including the cost of defending them.
Do platforms need to set supplier insurance requirements?
Usually yes. We help you write minimum limits into supply-side terms and verify certificates without adding onboarding friction.
What cyber limits do platform businesses carry?
Limits scale with record count and payment volume. Series A operators commonly sit between $2M and $6M with a matched retention.
How does general liability work for a marketplace?
It answers third-party bodily-injury and property-damage claims, including many that begin off-platform but name you anyway.
Are peer-to-peer disputes and safety incidents covered?
Yes, where the platform is named. Coverage turns on the allegation rather than on which side of the marketplace filed it.
What about vicarious liability for user conduct?
We underwrite it explicitly rather than leaving it to a silent exclusion, then set limits against your transaction mix.
Do I need cover for both sides of the marketplace?
The platform policy sits at the centre; supply-side requirements and optional embedded cover handle the rest.
How does cover differ for digital versus physical goods?
Physical fulfilment pulls weight toward general liability and products cover; digital marketplaces lean on Tech E&O, Media and Cyber.
