When should a Boston startup first buy D&O insurance?

The practical answer: when you take institutional money or add an outside board member. Many founders bind coverage as a closing condition of their seed or Series A. Some buy earlier — once there's a board making consequential decisions about equity, hiring, and spending, the exposure exists.

Do investor board members really get sued at private companies?

Claims against private-company boards are less publicized than public-company securities suits, but they happen — typically from other investors, founders, former employees, or creditors. That's precisely why VC firms insist portfolio companies carry D&O before their partners join a board.

Is D&O insurance required by Massachusetts law?

No. The requirement is contractual — written into financing documents — and practical, because experienced directors won't serve without it. Massachusetts corporate law permits indemnification of directors and officers, but indemnification is only as good as the company's balance sheet, which is exactly what D&O insurance backstops.

What's the difference between D&O and E&O?

D&O covers claims against leadership for how the company is managed and governed. E&O covers claims that your product or service failed and harmed a customer. A SaaS company being sued by a customer over an outage is an E&O matter; the same company sued by an investor over fundraising disclosures is a D&O matter. Most startups need both.

D&O Insurance for Boston Venture-Backed Startups

The most common trigger for buying D&O insurance in Boston isn't a lawsuit — it's a term sheet. When a venture firm leads your round, the financing documents almost always require the company to put directors and officers insurance in place within a set window after closing, because the investor taking a board seat wants protection before their first board meeting. If you're a founder in Boston, Cambridge, or anywhere in Massachusetts heading toward a seed, Series A, or Series B close, this guide covers what D&O actually protects, why biotech boards carry distinctive risk, and what to expect on pricing and process.

What D&O Insurance Covers — and Who It Protects

Directors and officers insurance protects the personal assets of your board members and executives — and the company's balance sheet — against claims alleging mismanagement, breach of fiduciary duty, misrepresentation, or other wrongful acts in running the company. A typical private-company policy has three insuring agreements: Side A protects individual directors and officers directly when the company can't indemnify them (most critically, in insolvency). Side B reimburses the company when it indemnifies its directors and officers. Side C covers the company itself as an entity for covered claims. For startups, claims most often come from disgruntled investors, co-founders, former employees, competitors, regulators, or — in a downturn or wind-down — creditors and bankruptcy trustees. Disputes over down rounds, recapitalizations, equity and option grants, and statements made during fundraising are recurring themes in the private-company claim data carriers publish.

Why Boston's Venture Density Raises the D&O Question Early

Greater Boston is one of the most active venture markets in the country, anchored by a deep bench of firms along the Route 128 corridor, in the Back Bay, and increasingly in the Seaport — plus the constant flow of university spinouts coming out of MIT and Harvard. That density has a practical consequence: Boston investors are experienced board members who know exactly what D&O coverage they expect, and their counsel writes the requirement into the stock purchase agreement or investor rights agreement as a condition or post-closing covenant. Typical investor requirements at financing: Seed: $1M in D&O limits is the most common request, occasionally $2M. Series A: $2M–$3M, often paired with a requirement that coverage be maintained while the investor holds a board seat. Series B and beyond: $3M–$5M+, with sophisticated boards starting to ask about Side A protection and policy quality, not just the limit number. Most early-stage companies buy D&O as part of a management liability package that also includes employment practices liability (EPL) and fiduciary liability. That matters in Massachusetts, where employment law is generally regarded as employee-friendly — wage-and-hour and discrimination claims are a real exposure for scaling startups, and EPL is frequently where the first claim actually lands.
