If you're a founder or COO at a venture-backed company, you've probably hit the moment where insurance stops being optional. Maybe a term sheet requires D&O before the round closes. Maybe an enterprise customer's MSA demands proof of tech E&O and cyber coverage. Either way, figuring out insurance for startups is rarely anyone's favorite job — so this guide lays out exactly which coverages you need, at which stage, and how to buy them efficiently. At OnePark Risk, we broker startup insurance for early-stage tech companies across New York, California, and Boston. The pattern is consistent: the right policies, bought at the right time, cost far less than scrambling for coverage while an investor or customer waits.
Most venture-backed tech companies build their insurance program around three specialty lines: Cyber insurance — covers data breaches, ransomware, business interruption from outages, and the regulatory and notification costs that follow. For any company holding customer data, cyber insurance for small businesses is now table stakes; for tech companies specifically, it's often contractually required. Tech E&O (errors & omissions) — covers claims that your product or service failed, underperformed, or caused a customer financial loss. Modern tech E&O insurance is usually written as a combined policy with cyber, since a software failure and a security failure often look identical in a lawsuit. D&O (directors & officers) — protects your personal assets, your co-founders', and your board members' when someone sues over a management decision: investors, regulators, competitors, even former employees. Our guide to directors and officers insurance covers how this works in a venture context. These three lines do different jobs, and none of them substitutes for another. A common and expensive misconception is that a general liability policy covers software failures or data breaches — it doesn't. GL handles bodily injury and property damage, which is why most startups also carry general liability insurance built for startups alongside their specialty lines, not instead of them.
### Incorporation to Pre-Seed At formation, your exposures are mostly practical: a lease that requires general liability, a state that requires workers' comp once you hire, and contractors who want certificates of insurance. Keep it lean — GL (often packaged in a business owner's policy), workers' comp where required, and cyber if you're already handling user data. ### Seed The seed round is when D&O typically enters the picture. Once outside investors take board seats, they're personally exposed — and most institutional investors require D&O as a closing condition. Founders are often surprised that D&O insurance quotes for seed-stage companies are more affordable than expected; early-stage placements with A-rated carriers are typically a modest line item relative to the round. This is also when many startups consolidate D&O with employment practices liability (EPLI) and fiduciary coverage into a single management liability insurance package, which usually prices better than buying each line separately. ### Series A By Series A, customer contracts drive the program. Enterprise buyers routinely require: Coverage Typical contractual requirement Tech E&O / Cyber $1M–$5M, often combined General liability $1M per occurrence / $2M aggregate Workers' comp Statutory limits Umbrella Sometimes, on larger deals If you're losing days in procurement because you can't produce a certificate, that's a solvable problem — a broker who works with tech companies can usually bind E&O/cyber quickly. Request an errors and omissions quote before the contract lands, not after. ### Series B and Beyond Growth-stage companies layer in higher limits, international coverage as you expand abroad, key person life insurance, and eventually IPO- or acquisition-readiness on the D&O tower. Limits that made sense at seed ($1M D&O, $1M cyber) usually step up to $3M–$10M+ as headcount, revenue, and board complexity grow.
