Startup insurance by funding stage: what changes, and when

Use the trigger, not the label

Funding stages are a useful shorthand for what a company looks like, but they are a poor instruction for what to buy. Two Series A companies can need very different programmes: one has forty staff, US customers and a regulated permission; the other has eight people and one pilot contract. What actually adds a layer of cover is an event, and the events cluster around rounds without being caused by them.

So this page works in two directions. The list below routes you to the detailed guide for your stage. The section after it sets out the triggers — the specific things that happen — so you can check whether you are already past one. If you want the whole picture from the top, start at our startup insurance guide.

The five stage guides

Pre-seed. Founders only, often no employees, building toward a first customer. The questions are whether the employers’ liability duty has been triggered yet, what your co-working licence requires, and what you are promising in early contracts.

Seed. First hires, first paying customers, first procurement questionnaires. Professional indemnity or tech E&O and cyber usually enter here, driven by contracts rather than by choice.

Series A. An institutional investor and, in most cases, an investor-nominated director. This is where D&O stops being optional in practice — not because the law requires it, but because the shareholders’ agreement and the board do.

Series B. Scale changes the questions: higher limits, international expansion, employment practices exposure as headcount grows, and a programme that has to be explained to a board and an audit process.

Series C and growth. Full programme management, structured limits, exit and transaction considerations, and an insurance history that will be examined in diligence.

If you would rather see the same journey as an interactive map, our startup and scale-up roadmap presents it stage by stage.

The triggers that add a layer

Your first employee who is not a qualifying director. This is a legal duty, immediately — employers’ liability cover under the Employers’ Liability (Compulsory Insurance) Act 1969. It is the only compulsory business cover in the list and it is triggered by a hire, not a round (employers’ liability insurance).

Your first contract with an insurance clause. Enterprise procurement specifies covers and limits, and sometimes requires cover to continue for a period after the contract ends. Read it before signing: it is a multi-year financial commitment written in a paragraph nobody negotiates.

Your first term sheet with an investor director. D&O follows the board, not the valuation. Once someone joins your board on behalf of a fund, the expectation is that the company protects them (D&O insurance for tech companies).

Your first office lease or co-working licence. Public liability is almost always a condition of occupying somebody else’s space (public liability insurance).

Your first customer outside the UK, and especially in the United States. Territory and jurisdiction wording decides whether a claim brought abroad is covered at all. This is a wording change, not a limit change, and it needs handling before the contract rather than after.

Your first material volume of customer data, or first security questionnaire. Cyber cover and the controls behind it become a sales requirement well before they become a risk-management decision (cyber insurance for startups).

Your first regulated activity. Permissions bring their own capital, conduct and insurance expectations, and they change how PI is structured.

Headcount past the point where HR is informal. Employment practices exposure grows with people and process, and it is usually bought as an extension to D&O rather than separately.

Where the round genuinely does matter

Two things really are tied to the round rather than to an operational event. The first is D&O, because the round is what puts an outside director on the board and what creates the shareholders’ agreement obligation. The second is diligence: investors will ask what you hold, and gaps found during diligence get fixed under time pressure and on worse terms. Our insurance checklist before a funding round exists for exactly that window.

Two traps between stages

Cover that stayed still while the company moved. Programmes bought at seed are commonly still in place two rounds later, with limits sized for a company that no longer exists, territories that exclude the markets you now sell into, and an activity description that predates the pivot. Insurers underwrite what you told them, and a description that no longer matches the business is a problem waiting for a claim.

Losing continuity when you switch. PI, cyber and D&O are claims-made. The policy that responds is the one live when the claim is made, and usually only for work done after the retroactive date. Moving insurer to save a modest amount, or letting cover lapse between rounds, can reset that date and quietly remove protection for everything you have already delivered. Continuity of cover is worth defending in the placement.

How Apex handles stage transitions

We would rather have the conversation before the trigger than after it. Practically that means knowing what is in your pipeline — the round, the first US customer, the enterprise contract, the first ten hires — and building a programme that can absorb them without an emergency. Bristol-based and FCA-regulated, and used to working to a completion date. If you want the covers explained rather than the sequence, go back to the startup insurance guide.

Frequently asked questions

Does insurance really change at each funding round?

Less than people assume. What changes cover is an event: a first employee, a first contract with an insurance clause, a first investor director, a first overseas customer. Those cluster around rounds without being caused by them, which is why it is more reliable to check the triggers than to buy by stage label.

At what stage do we need D&O?

In practice, when an outside director joins your board — typically at Series A, sometimes earlier with an active angel or a seed fund that takes a board seat. D&O is never a UK legal requirement; the pressure comes from the shareholders’ agreement, from investors, and from directors who will not serve without it.

We are raising in three months. When should we sort insurance out?

Now, not at completion. Diligence will ask what you hold, and anything missing gets bought late, under pressure and often on worse terms. Working backwards from the completion date also avoids the common problem of D&O being placed after signing, when the board it is meant to protect is already in place.

Can we just upgrade limits later instead of buying now?

Limits can be increased later, but continuity cannot be bought back. Professional indemnity, cyber and D&O are claims-made: they respond to claims made while the policy is live, usually only for work done after a retroactive date. A gap between policies, or a reset retroactive date on switching insurer, removes protection for work you have already delivered.
