Series A Data Room: The 23 Tabs Investors Expect
An institutional-grade data room is dull and that is the point. Diligence teams want to find what they expect, where they expect it, with consistent naming and versioning. Here is the structure that turns a partner's "send the data room" into a term sheet inside two weeks rather than four.
Your data room is not a filing cabinet. It is a structured argument. Each tab answers a specific question the diligence team is trained to ask; each document inside each tab is evidence for that argument. The standard institutional shape runs to 23 tabs across seven sections. Missing tabs and inconsistent naming are the two most common reasons diligence teams report a data room as "not ready" — more common than missing documents inside individual tabs.
The seven sections are: Corporate, Commercial, Financial, Legal & Governance, People, Product & Technology, and Go-to-Market. Each maps to one or more of The Opagio 12 value drivers, which means the asset register output from the Round Readiness Diagnostic maps one-for-one onto this structure.
Corporate (tabs 1–3)
The starting section. Everything in it is binary — either clean or it's not. Missing items here create two-week delays while diligence teams wait for documents to be produced.
Tab 1 — Company information. Certificate of incorporation, memorandum and articles of association, registered office details, any trading names, change-of-control history. The question it answers: "Who is the company and is it genuinely incorporated as you say?"
Tab 2 — Cap table and ownership. Current cap table (fully diluted), share certificates, option pool size and utilisation, SAFE and convertible note register, any outstanding warrants, anti-dilution provisions, and dates/prices of every prior funding round. The question it answers: "Who owns what, and what happens to us when we put new money in?"
Tab 3 — Corporate governance. Board composition, board minutes for the last 12 months, shareholder resolutions, investor rights agreements from prior rounds, any enforceable pre-emption or drag-along rights. The question it answers: "Who decides what, and can this round complete without minority-shareholder drama?"
Commercial (tabs 4–6)
This section is where diligence starts actually digging. The cap table might be clean; the commercial story is where the investment case is made or lost.
Tab 4 — Customer contracts and commitments. Top-20 customer contracts, master services agreements, any non-standard terms (exclusivity, non-compete, uncapped liability), renewal and churn history, and a customer-concentration analysis. The question it answers: "Is the revenue as contracted as you claim, and how much of it is at risk?"
Tab 5 — Sales pipeline and bookings. Pipeline by stage, conversion rates by stage, average sales cycle by segment, booked-not-yet-delivered revenue, and a reconciliation of pipeline value to recent bookings. The question it answers: "Is the forecast credible and is the sales motion scalable?"
Tab 6 — Partnerships and channel. Reseller agreements, integration partnerships, white-label deals, any pending MOUs and their commercial weight. The question it answers: "How dependent is distribution on relationships outside the company?"
Financial (tabs 7–10)
The deepest section in most data rooms. This is where the forecast gets pressure-tested and where diligence teams build their own model alongside yours.
Tab 7 — Management accounts and financials. Monthly management accounts for the last 24 months, audited accounts for every completed year, trial balance, and detailed breakdowns of revenue, COGS, operating expenses, and headcount.
Tab 8 — Forecast and assumptions. Three-year forecast model (monthly Year 1, quarterly Years 2–3), explicit assumption schedule, sensitivity analyses on the top five drivers, and historical actuals-vs-forecast comparison for any prior forecasts you produced. Diligence teams look hard at the last point: has the forecast been historically accurate?
Tab 9 — Unit economics. Cohort retention curves, segmented LTV, CAC by channel, CAC payback by segment, gross margin by product line, contribution margin construction. Blended numbers read as evasion; segmented numbers read as operational maturity.
Tab 10 — Banking and treasury. Bank statements (last 6 months), cash position, cash runway calculation, any drawn or undrawn debt facilities, payment terms with top suppliers. The question it answers: "How fast is the burn and when do you run out?"
Legal & Governance (tabs 11–14)
A single missing IP assignment can tank an investment memo. Legal diligence is where founders with otherwise strong businesses lose two to three weeks scrambling to produce documents.
Tab 11 — Intellectual property. All granted patents, patent applications, registered trademarks, registered designs, and a schedule of material trade secrets with protection measures. Every IP assignment agreement from every founder, employee, and contractor who contributed to the IP. Missing assignments are the single most common Series A legal flag.
Tab 12 — Material contracts (non-customer). Supplier agreements, landlord agreements, any material licences (inbound and outbound), and any agreements with change-of-control clauses that a Series A round could trigger.
Tab 13 — Regulatory and compliance. Evidence of regulatory registrations where applicable (FCA, CQC, etc), GDPR compliance documentation, data processing agreements, information security certifications (SOC 2, ISO 27001), and any ongoing regulatory correspondence.
Tab 14 — Litigation and disputes. Any current or threatened litigation, any recent settled disputes, any employment tribunal history, and any known commercial disputes whether or not currently in process. Saying "none" is perfectly acceptable; hiding any of these is not.
Warning: The fastest way to lose momentum with a diligence team is to produce documents in response to each question rather than having them pre-loaded. Every "we'll get that to you tomorrow" extends diligence by a day — compound that across 23 tabs and a two-week process becomes six.
People (tabs 15–17)
Tab 15 — Team and organisation chart. Current org chart, headcount by function, any planned near-term hires, employment contracts for key executives, and any unresolved compensation obligations.
Tab 16 — Founder and exec background. CVs, any prior company history (including any that did not succeed — diligence teams find these anyway), any non-compete or non-solicit obligations inherited from prior employers. Honesty on prior company history is almost never a problem; discovery of undisclosed history almost always is.
Tab 17 — Compensation and equity. Salary bands, bonus structures, option grant history, option strike prices, and any promises of equity not yet formalised. Unformalised promises surface late in diligence and are almost always the single hardest thing to clean up on a short timeline.
Product & Technology (tabs 18–20)
Tab 18 — Product overview and roadmap. Product demonstrations or recordings, feature inventory, product roadmap for the next 12–18 months, prioritisation methodology, and any major architecture decisions ahead (e.g. cloud migrations, platform rewrites) that materially affect the operating model.
Tab 19 — Technology architecture. High-level architecture diagram, technology stack, hosting and infrastructure, any material third-party dependencies, and the dependency risk assessment. Key-person risk on engineering is a real diligence question — "what happens if your CTO leaves next month?" is asked often and answered poorly.
Tab 20 — Security and compliance posture. Security certifications, penetration test reports, incident history (real disclosures here are far less damaging than later discovery), backup and disaster recovery plans.
Go-to-Market (tabs 21–23)
Tab 21 — Sales motion and team. Sales team structure, quota model, commission plan, average ramp time for a new hire, and any known gaps in the current sales capacity.
Tab 22 — Marketing and brand. Marketing spend by channel, attribution methodology, content strategy, PR history, brand guidelines, and any brand-related IP (trademark registrations, content libraries with reuse value).
Tab 23 — Customer success and retention. CS team structure, renewal process, churn by cohort and segment, expansion motion, net revenue retention by segment, and any material customer advocacy programmes.
Key Takeaway: A data room that is structured like this turns the diligence question "what do you have?" into "what does the evidence in tab X actually say?" The second question is the one partners want to be asking.
Building this from the asset register
The Round Readiness Diagnostic scores your intangible asset base across The Opagio 12. Each driver maps onto one or more of the 23 tabs above, so the asset register output is the data room skeleton — not a parallel document that has to be translated. Starter tier unlocks the full asset-register flow with unlimited diagnostic runs.
For the companion walk-through of the question set diligence teams use when they navigate this data room, see the 47 questions Series A diligence asks. For the full Series A preparation sequence, see Round Ready Academy Lesson 5: building the Series A asset register.
The Bottom Line
The 23-tab shape is not optional. It is the shared language diligence teams expect to read. The asset register built from the diagnostic maps one-for-one onto the tabs — so the work is done in the shape that becomes the output, not in the shape that has to be translated later.
