Errors & Omissions (Tech E&O) Insurance in California

What E&O Insurance Covers for California Tech Companies

E&O insurance in California — for software companies, usually written as technology errors & omissions — covers claims that your product or professional services failed, underperformed, or caused a client financial loss. Core coverage includes:

• Defense costs — attorneys' fees from day one, which in California's legal market are often the largest part of any claim.
• Damages and settlements — amounts you become legally obligated to pay for a covered claim.
• Software failure and negligence claims — your platform goes down during a customer's critical window, a data migration corrupts records, an integration error costs a client revenue, a missed deliverable triggers a dispute.
• Contractual liability tied to your services — including liability you assume under the indemnification clauses customers demand (more on that below).

A modern tech E&O policy is typically paired — often on the same form — with cyber coverage, because a security failure and a service failure are frequently the same incident. If a breach takes your platform offline and customers sue over the outage, you want one carrier responding, not two arguing about whose problem it is.

Why California Contract Norms Drive E&O Requirements

California's tech economy runs on master services agreements, and those agreements have hardened into a fairly predictable set of demands on vendors:

• Indemnification clauses. Nearly every enterprise MSA out of a Bay Area or LA legal department requires you to indemnify the customer for losses arising from your negligence, your product's failure, or third-party claims. You're contractually absorbing risk — E&O is how you finance it.
• Required insurance schedules. California enterprise contracts routinely specify minimum E&O limits — $1M per claim is the floor, and $2M–$5M is common once you're selling to large enterprises, financial institutions, or healthcare organizations. Many also require coverage to continue for a period after the contract ends.
• Certificates before kickoff. Procurement teams won't issue a PO or grant production access until they hold a certificate of insurance matching the contract. We issue certificates same-day for our clients precisely because deals stall on this.
• Limitation-of-liability carve-outs. Sophisticated buyers increasingly carve indemnification and confidentiality breaches out of liability caps — meaning your theoretical exposure under a single contract can far exceed the contract's value. That asymmetry is the strongest argument for real E&O limits, not minimum ones.

If you're selling into Silicon Valley enterprises, this isn't a someday problem. It usually shows up in your first or second meaningful enterprise negotiation.

Tech E&O Insurance for California SaaS and Software Companies

Tech E&O insurance in California gets underwritten on a handful of factors: your revenue, what your software does, who your customers are, your contract discipline, and your security posture. A few patterns we see with Silicon Valley and SF SaaS companies:

• AI and data-heavy products get more questions. If your product makes decisions or generates output customers rely on, expect underwriters to dig into your testing, human-in-the-loop controls, and disclaimers. The market still quotes these risks — just more carefully.
• Fintech, healthtech, and infrastructure carry higher severity. Customers in those verticals also demand the highest limits, so coverage and contract requirements rise together.
• Combined E&O/cyber is the default. We typically place a single technology E&O + cyber policy rather than separate towers — cheaper, with no coverage gaps.

E&O is one piece of a California startup's full program alongside D&O, cyber, and workers' comp — our California startup insurance guide shows how the whole stack fits together by stage.

What Does E&O Insurance Cost in California?

For early-stage California software companies, tech E&O (usually combined with cyber) typically runs in the broad range of $2,000–$6,000 per year for $1M–$2M in limits at seed through Series A, with pricing scaling on revenue, limits, product risk, and claims history. Pre-revenue companies buying coverage to satisfy a first enterprise contract often land at the bottom of that range; companies with meaningful ARR or higher-severity products land higher.

Two things to know: higher limits are usually cheaper than founders expect — going from $1M to $2M rarely doubles the premium — and the gap between a bad policy and a good one at the same price is large. Exclusions for contractual liability can gut the coverage your MSA assumes you have. Our E&O insurance cost guide covers the pricing drivers in more depth.

How the Quote Process Works with OnePark Risk

We've stripped the process down to what a founder or COO actually has time for:

1. A short application — basics about your product, revenue, customers, and security controls; under 15 minutes for most startups.
2. We shop the market — taking your risk to the carriers that specialize in venture-backed tech and negotiating terms, not just price.
3. You pick, we bind — quotes back within a few business days, and certificates of insurance issued same-day once bound so your contract can close.

If a live deal is waiting on a certificate, tell us — we prioritize quote-to-bind timelines around contract deadlines.
