A fundraise has two very different document moments, and most founders only plan for the first.

Moment one is outreach. You send a deck to 30, 50, maybe 100 investors. You want to know who opened it, how long they spent on the financials slide, and whether a partner forwarded it to colleagues.

Moment two arrives after a term sheet. The lead investor’s lawyers send a diligence request list, and suddenly you need your cap table, option ledger, IP assignments, customer contracts and board minutes in one organised place.

A tool that is good at one moment is not always good at the other. Decide early whether you want one product for both, or two products and a handover.

What investors look at, by round

RoundTypical investor focusDocuments to have ready
Pre-seed and seedTeam, market, early tractionDeck, a one-page metrics summary, cap table
Series ARepeatable revenue and unit economicsMonthly metrics, cohort data, key contracts, IP assignments, incorporation documents
Series B and laterScale, governance and riskAudited or reviewed accounts, board minutes, option plan, material contracts, data protection and security policies

At seed, the “data room” might honestly be a tracked link to a deck plus a short folder. By Series B, investors expect something closer to an M&A room, with a numbered index and a way to ask questions.

What founders get wrong

Sending attachments. Once a PDF is in someone’s inbox, you have lost control of it. A tracked link lets you see engagement and switch access off.

Over-sharing early. Your customer list, pricing and product roadmap do not belong in a first-meeting folder. Hold them back until an investor is committed to diligence, and consider stricter download controls for anything that would help a competitor.

Letting the cap table drift. The single most common delay in a priced round is a cap table that does not match the share register or the option ledger. Fix it before the room opens, not during legal review.

Skipping the analytics. If an investor spent four minutes on your deck and never reached the financials, that is useful. If another went back to the competition slide three times, prepare for that conversation.

Founder tipCreate a separate link or permission group for each investor firm. Analytics are only useful if you can tell who did what, and you can revoke one firm’s access without breaking the others.

Two tools or one?

Plenty of founders pair a deck-sharing tool with a separate room for diligence. That works, but it means two subscriptions, two sets of permissions and a migration in the middle of your round.

DocSend is the specialist for moment one: strong analytics, simple links, per-user pricing. It lacks Q&A and bulk upload, so a full diligence room is not its natural job. SecureDocs and Ellty are built as proper rooms with flat monthly prices, which makes them easier to keep open from the first deck through to closing. Digify sits in between, with strong rights management for sensitive material. Read the reviews of Ellty, DocSend, SecureDocs and Digify for the details.

Budgeting

At seed, spend as little as you can while still getting tracking and revocable access. Most founders on a per-user plan only need a single seat.

From Series A, budget for a proper room for three to four months. That is about how long a priced round takes from first meeting to money in the bank, sometimes longer. At the published starting prices in our data (Digify $120, Ellty $149, SecureDocs $250 a month), a three to four month round costs roughly $360 to $1,000 in room fees. Prices are indicative and change, so check them on the pricing page and with the provider.

Most of these tools offer a free trial, so set up a test room with your real deck before committing.

A quick readiness check before you launch

  • Deck and one-page metrics summary are final and dated.
  • Cap table reconciles with the share register and option ledger.
  • Every founder and early employee has signed an IP assignment.
  • Material customer and supplier contracts are scanned and searchable.
  • You know which folders unlock only after a term sheet.

Frequently asked questions

Do seed-stage startups need a data room?

Not a full one. A tracked deck link and a small folder with your cap table and incorporation documents is usually enough. Investors at seed rarely run deep legal diligence.

What should be in a Series A data room?

Corporate documents, cap table and option ledger, IP assignments, key customer and supplier contracts, monthly financials and metrics, and employment agreements for the founding team. The lead investor's lawyers will send their own list; match your index to it.

Can investors see who else has looked at my data room?

Not in a properly configured room. Each investor sits in its own group and sees only its own activity. Check this during your free trial by logging in as a test investor.
