What does tech E&O insurance cover?

Most people asking this are holding a customer contract that demands the coverage — founders on r/msp are candid that enterprise contracts and fundraising, not risk analysis, drive the purchase. So the useful version of the question isn’t “what’s in the brochure,” it’s whether the form matches the promises in your MSA and where the edges are. Tech E&O is professional liability written for businesses whose product is technology: it pays to defend and settle claims that your product or service failed a client.

The claims it exists for

Founder Shield’s taxonomy of tech E&O claims is a fair map of the insuring agreement:

• Failure to perform. The project doesn’t ship, the platform doesn’t do what the contract promised, the migration breaks something it shouldn’t have. This is the core of the coverage.
• Negligence. Human mistakes in delivering professional services — a bad configuration, an error that cascades into client downtime.
• Software errors that cost clients money. The bug itself isn’t the claim; the client’s financial loss traced to it is.
• Copyright infringement. Allegations you shipped protected code or content — coverage on this varies by form, and it’s copyright, not patents.
• Defamation and media claims. On many forms, liability for user-generated or published content.

What the policy is buying you in every scenario is the same two things: defense costs from the first demand letter, and settlement or judgment up to the limit.

What it doesn’t cover

• Bodily injury and property damage. That’s general liability’s job; E&O forms exclude it.
• Your own breach costs. Forensics, notification, ransomware response are first-party cyber coverage. Most tech E&O today is sold blended with cyber — TechInsurance’s baseline product covers “mistakes and data breaches” in one policy — but a standalone E&O form leaves the first-party side bare. The boundary is mapped in cyber insurance vs tech E&O.
• Pure contract liability — sometimes. Here the market genuinely conflicts: forms advertise “failure to perform” coverage while carrying breach-of-contract or delay exclusions, and Founder Shield notes some policies push contract and delay claims outside coverage. Whether your form covers a contract-based suit turns on its contract-liability exclusion and carve-backs. Read that clause before you certificate the policy to a customer.
• Performance guarantees and warranties. Insuring a promised uptime number is not what E&O does; it responds to negligence-based claims, not to guarantees you chose to sign.

Software also sits awkwardly next to product liability — that boundary has its own page.

Setting the limit

Vouch’s limit guidance matches what we see in contracts: the floor is whatever your largest client’s insurance clause demands — enterprise and regulated customers “require proof of specific E&O coverage levels before signing” — and the sanity check is the worst plausible loss from a single mistake, defense costs included. Limits should be revisited when you land bigger contracts, not on a calendar. If the purchase is contract-driven, the broader stack is covered in what insurance startups need to close customer contracts.

Questions founders actually ask

How much tech E&O insurance do I need? Start from the insurance clause in your largest contract — that number is a requirement, not a suggestion — then test it against your worst single-client failure. We don’t quote premium figures; the limit decision is the one you control.

I need tech E&O for my startup — is it different from regular E&O? Structurally the same product; the difference is definitions. A generic E&O form written for consultants may not define software, SaaS delivery, or technology products as covered services. The tech form does, and usually adds cyber.

Does tech E&O cover data breaches? The lawsuits that follow a breach of your product, yes on most blended forms. Your own response costs, only if cyber coverage is attached — check for it rather than assuming.

Does tech E&O cover breach of contract? The most form-dependent answer in this line. Failure-to-perform coverage and contract exclusions coexist on the same policies; the carve-back language decides, and forms conflict enough that we won’t generalize.
