What Is D&O Insurance?
D&O insurance — directors and officers liability — protects the individual people who lead a company, and often the company itself, against claims that they mismanaged the business. In plain terms, it covers the legal defense and any settlement when investors, regulators, competitors, or other parties allege wrongdoing by leadership: breach of fiduciary duty, misrepresentation, a misleading disclosure, or a decision that allegedly harmed shareholders. What makes D&O different from most business insurance is that it can protect a director's or officer's personal assets, because these claims are frequently brought against individuals by name, not just the corporate entity. This guide explains the Side A/B/C structure, who actually needs D&O, when funded startups are expected to buy it, and what it costs today. It's written for founders, CFOs, and general counsel preparing for board governance and institutional investment.
What D&O Insurance Covers
D&O responds to "management liability" claims — allegations about how the company was run, rather than about a product defect or a data breach. Typical triggers include:
- Breach of fiduciary duty. Claims that leadership failed to act in the best interests of shareholders or the company.
- Misrepresentation. Alleged inaccurate or misleading statements to investors, including in a fundraising round.
- Mismanagement. Decisions or oversight failures that investors or regulators say caused financial harm.
- Regulatory and investigative actions. Government or regulator inquiries directed at the conduct of directors and officers.
Crucially, D&O pays defense costs even when allegations are unproven — and defending a management claim can be expensive long before any finding of fault. For where D&O sits among other startup coverages, see our management liability insurance overview.
The Side A/B/C Structure
D&O is usually written in three coordinated parts, which is worth understanding because it explains who gets protected:
| Side | Who it protects | What it does |
|---|---|---|
| Side A | Individual directors and officers | Pays when the company cannot indemnify them (e.g., insolvency or legal bar) |
| Side B | The company | Reimburses the company when it indemnifies its leaders |
| Side C | The company (entity) | Covers the company itself for covered claims, commonly securities-related |
The practical takeaway: Side A is the personal backstop that protects an individual's own assets, which is exactly why experienced directors ask whether a company carries D&O before joining a board. You can dig deeper in our startup D&O hub.
Who Needs D&O — and When
D&O matters most for companies with outside investors and a real board, because that governance structure is what creates the exposure. A solo-owned, self-funded business has fewer of these claims; a venture-backed company with institutional shareholders and board seats has many more potential claimants.
The clearest trigger is fundraising. At a Series A, institutional investors typically require D&O coverage before or at closing, because board seats appear and investors want their directors protected. Illustrative scenario: a startup negotiating a Series A finds the term sheet conditions closing on a bound D&O policy naming the new investor directors — a common reason founders buy D&O on a deadline.

What D&O Insurance Typically Costs
D&O pricing depends on your funding stage, the amount raised, your financials, industry, and litigation history; companies on an IPO track or in heavily regulated sectors pay more. As a directional guide, typical market ranges as of 2026 place early-stage D&O programs in the four-figure range annually for a starter limit, scaling with the size of the round and the limit purchased — a market range, not a quote. For how providers and pricing vary, see our directors and officers insurance guide.

Frequently asked questions
Does my startup need D&O insurance before it has revenue?
Often yes, if you've raised institutional money or are about to. Investors frequently require D&O at a priced round because board members want personal protection, regardless of whether the company is generating revenue yet.
Does D&O protect me personally, or just the company?
Both, depending on the side of coverage. Side A protects individual directors and officers — including their personal assets — when the company can't indemnify them, while Sides B and C protect the company. That personal protection is a key reason directors insist on it.
How is D&O different from general liability or E&O?
General liability covers bodily injury and property damage; tech E&O covers claims that your product or service failed a client. D&O is distinct — it covers claims about how leadership managed the company, such as breach of fiduciary duty or misrepresentation to investors.
When do investors require D&O coverage?
Most commonly at a Series A or other priced round, where institutional investors take board seats and condition closing on having D&O in place. It's wise to budget for it as part of fundraising rather than treating it as an afterthought.
