What a Data Room Actually Contains Before a UK Funding Round

What a data room is for

A data room is a secure online folder, usually built on a platform like DocSend, Google Drive with restricted access, or a dedicated tool such as Carta or a virtual data room provider, where a startup puts every document an investor needs to do due diligence. It is opened once a term sheet is signed or sometimes earlier, during later-stage due diligence, so that investors and their lawyers can verify what founders have told them in the pitch.

The point of a data room is speed and trust. Investors have seen hundreds of pitches that sound great and fall apart under scrutiny. A clean, complete data room signals that a founding team runs a tidy business, and it lets lawyers and analysts do their job without weeks of back and forth chasing missing documents. A disorganised or incomplete one is a common reason rounds slip or fall through at the last stage, even after terms have been agreed.

Corporate and legal documents

This is usually the first thing a lawyer will ask for. It typically includes the certificate of incorporation, articles of association, register of members and register of directors, board minutes and shareholder resolutions going back to formation, and details of any subsidiaries. Investors want to see the full history of who owns what and how decisions have been made, because gaps here can point to unresolved disputes or informal arrangements that were never properly documented.

Also expected: copies of all previous funding round documents, including any SEIS/EIS advance assurance letters, convertible loan note or SAFE agreements, and shareholder agreements. If founders have ever issued shares informally, done a friends-and-family round on a handshake, or forgotten to file something with Companies House, this is where it surfaces. Getting this tidied up before opening the data room, rather than during due diligence, saves a huge amount of time.

The cap table

A current, accurate capitalisation table sits near the top of every checklist. It should show every shareholder, their share class, the number of shares, any options granted under an EMI scheme or otherwise, and vesting status. Investors will model dilution from the new round against this table, so any inconsistency between what founders claim and what the cap table shows raises immediate red flags. Many rounds now use cap table software specifically so this document can be shared as a live, verifiable source rather than a spreadsheet someone might have edited by hand.

Financials

Expect to include historic management accounts, any audited or reviewed statutory accounts, current bank statements, a detailed budget and cash flow forecast, and a clear breakdown of burn rate and runway. SaaS and subscription businesses will also need a build-up of recurring revenue metrics and cohort data, and any business with meaningful revenue should be ready to show invoices or contracts that back up the top-line numbers, not just a summary spreadsheet.

Investors doing financial due diligence are checking that the numbers in the pitch deck reconcile with the underlying accounts. Discrepancies do not automatically kill a deal, but unexplained ones do.

Commercial and customer documents

This covers signed customer contracts, supplier and partnership agreements, standard terms of service, and any material commercial arrangements such as exclusivity clauses or minimum volume commitments. Investors want to understand customer concentration, contract length, and whether revenue is genuinely locked in or cancellable at short notice. For B2B startups, redacted versions of key contracts are often acceptable if commercial sensitivity is a concern.

IP, tech and data

For most startups this means proof that intellectual property sits with the company and not with a founder, a former co-founder, or a contractor who was never asked to assign rights. Include any patents or trademark filings, key employment contracts and contractor agreements with IP assignment clauses, and, for data-driven or AI businesses, documentation of data provenance and licensing terms for any third-party data or models in use. Gaps in IP assignment are one of the most common reasons legal due diligence drags on, because they can be genuinely hard to fix after the fact.

People and employment

This includes employment contracts, consultancy agreements, an organisation chart, details of any EMI option scheme and who holds options, and information on notice periods and any ongoing disputes or grievances. Investors want reassurance that key people are actually tied to the business through proper contracts and vesting, not informal understandings.

Insurance, compliance and disputes

Expect to include any D&O insurance policy, evidence of relevant regulatory registrations (for example ICO data protection registration, FCA authorisation if relevant), and a full disclosure of any current or threatened litigation. Investors will specifically ask whether there is anything the founders have not disclosed, and honesty here matters more than a clean-looking answer, because anything uncovered later can undermine trust in the whole deal.

Keeping it simple

The practical advice from lawyers and experienced founders is consistent: build the data room’s structure early, even before a round is planned, and update it continuously rather than scrambling in the weeks before a raise. A logical folder structure, consistent file naming, and a short index document at the top level make an enormous difference to how quickly investors move from term sheet to completed round. For the current expectations on company filings and statutory records, founders should check gov.uk and Companies House guidance directly rather than relying on templates that may be out of date.
