Startup insurance: D&O, E&O & cyber from seed to Series A

Most founders think about insurance for the first time when a term sheet or a customer contract demands it — usually with a deadline attached. Here's what a venture-backed Bay Area startup actually needs, in plain English, and roughly when each coverage tends to become non-negotiable from seed to Series A.

Start with the basics (pre-seed / seed)

Before the fancy stuff, two unglamorous policies do most of the work:

General Liability (GL): Third-party bodily injury and property damage. Often required by your office lease or co-working space (WeWork-style spaces ask for a certificate).

Workers' Compensation: Legally required in California the moment you have employees — even one. Don't skip this; it's a state mandate, not a choice.

If you handle company-owned laptops and equipment, a simple Business Owner's Policy (BOP) can bundle property with GL affordably.

The three that matter most for funded startups

Directors & Officers (D&O). Protects your company's leadership — and increasingly the company itself — from claims tied to management decisions: investor disputes, misrepresentation, breach of fiduciary duty. This is the one VCs care about. Many term sheets require D&O as a closing condition, because the investors taking board seats want to be protected. If you're raising a priced round, expect to bind D&O at or near close.

Errors & Omissions (E&O) / Professional Liability — often combined with Tech E&O. Covers claims that your product or service failed, caused a financial loss, or didn't perform as promised. For a SaaS or services startup, this is your core product-risk coverage, and enterprise customers frequently require it in the contract before they'll sign.

Cyber Liability. Covers data breaches, ransomware, notification costs, and related liability. If you store customer data — and nearly every startup does — this is essential. Like E&O, it's increasingly a contractual requirement from larger customers and is often bundled with Tech E&O.

A rough timeline of when each kicks in

Signing an office lease? → General Liability.

First employee? → Workers' Comp (required by law).

Closing a priced/VC round? → D&O (often a term-sheet condition).

Selling to enterprise customers? → E&O + Cyber (often a contract requirement).

Growing headcount and revenue? → Revisit limits, add Employment Practices Liability (EPLI) for employee-related claims.

Two founder mistakes to avoid

Buying coverage the week of a deadline. Underwriting D&O and cyber takes time, and rushing it costs leverage and money. Line it up before the close, not during the scramble.

Setting limits by guesswork. The right limits depend on your round size, customer contracts, and data exposure. This is exactly where a broker who works with startups earns their keep.

Key takeaways

GL and Workers' Comp come first — lease requirements and California law, respectively.

D&O is the VC coverage, frequently required as a condition of closing a priced round.

E&O and Cyber are the customer coverages, commonly required in enterprise contracts.

Set up coverage before the deadline — underwriting takes time, and right-sizing limits matters.
