Founders and early-stage boards run into directors and officers exposure earlier than most other sectors, and often at a point where the personal balance sheet is thinnest. This entry sets out why UK startups need D&O once external investors join the cap table, the specific claim triggers we see in venture-backed businesses, how Side A cover protects founders and independent non-executives, and where D&O sits alongside professional indemnity, cyber and employment practices cover in a growth-stage programme.
The moment a startup accepts external money — angel, SEIS, EIS, seed VC, Series A — the board acquires a set of stakeholders whose interests are legally distinct from the founders’ interests. The general duties in Companies Act 2006 sections 171 to 177 apply to every director regardless of company size or age. Section 172 (duty to promote the success of the company for the benefit of members as a whole) becomes contested territory the moment there is more than one class of shareholder. Derivative claims under sections 260 to 264, unfair-prejudice petitions under section 994, and disputes over information rights all attach to directors personally.
Venture-backed businesses carry a further exposure because investor boards ask directors to sign warranties and disclosures in shareholders’ agreements and investment documents. When a subsequent round produces down-round tension, or when a target is missed and management is replaced, those signed documents become the starting point for claims.
Side A responds when the company cannot indemnify the director — typically after insolvency or where the company’s articles do not extend to the specific loss. Side B reimburses the company when it has stepped in to indemnify a director under a qualifying third-party indemnity provision (section 234 Companies Act 2006). Side C covers the entity for securities claims, which for private-company startups is a limited head but becomes central at IPO or dual-listing.
The extensions that matter for startups are pre-claim investigation costs, outside directorship liability (for founders who sit on portfolio company or subsidiary boards), employment practices liability, and specific carve-outs to the insured-versus-insured exclusion so that shareholder-brought derivative claims are not shut out.
Deliberate dishonesty and improper personal profit are excluded once established by final adjudication. Prior known circumstances — anything the founders knew about before inception — are excluded, and the proposal-form disclosure is the moment to declare disputed matters honestly rather than optimistically. Bodily injury, property damage, and pollution sit on other policies. Claims by one insured against another are excluded except where the standard carve-outs apply for shareholder actions and employment claims.
The Companies Act 2006 duties apply from day one. The Insolvency Act 1986 sections 213 (fraudulent trading) and 214 (wrongful trading) are the routes a liquidator will use if a runway miscalculation puts the business into administration — and the Company Directors Disqualification Act 1986 section 6 sits behind those. The Enterprise Investment Scheme rules (Income Tax Act 2007 Part 5) and Seed EIS rules (Part 5A) do not create direct director liability, but they create a documentary trail that investors will read closely if the business fails.
For fintech, healthtech, marketplace and other regulated-sector startups the FCA’s SMCR framework, the Payment Services Regulations 2017, and sector-specific authorisation requirements bring further personal-accountability exposure. Consumer Duty (PRIN 2A) applies to authorised firms from July 2023 and travels with senior managers.
D&O responds to the founder’s decisions as a director — how the board raised capital, allocated resources, disclosed to investors, or exited the business. Professional indemnity responds to the company’s services delivered to its clients — a SaaS platform outage, a coding error, bad advice given to a customer. In practice the two policies live next to each other, and where the wordings are not aligned the client either pays for double cover or carries a gap. A specialist broker looks at the definitions of ‘claim’ and ‘insured’, the notification triggers, and the retro-dates across both policies to make sure the two towers actually work together.
A pre-Series B company misses its plan and takes a bridge round at a materially lower valuation. Two early investors bring a claim naming the two founder-directors personally, alleging that projections shared during the previous round were misleading and that the board failed to disclose material adverse information ahead of the bridge. Legal costs to defend the personal position through the pre-action correspondence, a Part 8 disclosure application and eventual mediation fall on the individuals. Side B reimburses the company for the indemnity extended to the founders under the articles; Side A responds where the company’s indemnification is limited by section 232 of the Companies Act 2006. Pre-claim investigation costs pick up counsel’s early advice on the section 994 unfair-prejudice route the claimants have hinted at.
