# Data Room Builder
The data room is where momentum goes to die or to accelerate. A messy,
slow-to-assemble room signals an undisciplined company and gives a wavering
investor a reason to drift. A clean, staged room signals "this founder runs a
tight ship" and shortens the path to wired funds.
## When to use this skill
Build it during [[fundraise-readiness-audit]] (you should be able to produce it
in days - 3 to 5 working days is the standard for a seed-stage company with
clean books), and stage it for sharing once a term sheet is near. Confirmatory
diligence runs against it; see [[fundraise-closing-mechanics]].
## Structure the room in tiers
Share progressively - not everything goes out on the first call.
### Tier 1 - shared early (builds confidence)
- Pitch deck and the one-page narrative memo.
- Key metrics dashboard with definitions (so numbers are not disputed later).
- Market sizing with assumptions ([[market-sizing]]).
### Tier 2 - shared at serious interest / pre-term-sheet
- **Financials**: historical P&L covering at least the trailing 24 months
(monthly granularity), the model/projections ([[financial-planner]]),
monthly burn and runway.
- **Metrics detail**: cohort/retention curves, CAC by channel, pipeline.
- **Cap table**: fully-diluted, plus prior SAFEs/notes ([[cap-table-manager]]).
- **Product**: roadmap, architecture overview, security posture.
### Tier 3 - confirmatory diligence (post-term-sheet)
- **Corporate**: incorporation docs, board consents, prior financing docs.
- **IP**: assignment agreements for every founder and contractor.
- **Customers**: top contracts (any customer over ~10% of revenue gets extra
scrutiny - have those contracts and their renewal terms ready), churn
detail, references.
- **People**: org chart, key employee agreements, option grants.
- **Legal**: any litigation, regulatory exposure, material contracts.
## Operating rules
- One source of truth per number. The metric in the deck, the data room, and
your mouth must match to the decimal.
- Label and date every file. A folder named "Final_v3_real" loses you trust.
- Track who has access and what tier they are in; close access within a week
of a deal dying - a stale open room is a leak waiting to happen.
- Keep an index document at the root so a partner can navigate without asking.
- Respond to any diligence document request within 24-48 hours. Slower than
that reads as "they don't have it" and stalls the deal clock; confirmatory
diligence should run 2-4 weeks, and slow responses are the usual reason it
doesn't.
## Anti-patterns
- Dumping everything on day one - it overwhelms and surfaces issues out of
context.
- A number in diligence that contradicts the deck. This is the single fastest
way to lose a deal; reconcile before you share.
- A room you cannot assemble until week three of diligence. Build it before you
raise, not during.
## Quality bar
- Every metric in the room reconciles to the deck and the model to the decimal,
with one named source of truth per number.
- The full Tier 1-3 structure exists before outreach starts, with a have /
need / drafting status on every item.
- Every file is labeled and dated; the root index lets a partner find any
document without asking.
- Access is logged per person per tier, and there is a plan to revoke it when
a deal dies.
## Deliverable
A tiered, indexed data room (folder structure plus a contents checklist marking
have / need / drafting), with every metric reconciled to a single source and an
access-tracking plan for the raise.
