The other party asks for your data room. You have 24 hours. This is exactly what should be in it - organized, ready, and nothing missing.

A data room or virtual data room (VDR) is a secure online space where you store and share confidential company documents. It's used during fundraising, due diligence, M&A, and any situation where sensitive information needs to go to an outside party in a controlled way.
Before data rooms existed, people would email PDFs around or hand over physical folders. Some still do. That's a mistake, you lose all visibility into who saw what, and you can't revoke access if a deal falls through.
A proper data room gives you access controls (who sees which documents), audit trails (who opened what and when), and security features like NDA gating and watermarking. Recipients expect this now. Not having one signals disorganization at exactly the wrong moment.
A data room is not the same as a Google Drive folder or a Dropbox link. Drive gives you file storage. A data room gives you controlled access, tracking, and security - which is what visitors and acquirers actually need when they're reviewing sensitive information.
Most data rooms cover ten core areas. Think of these as the folders inside your room. Some viewers will want to see all of them. Others will focus on two or three depending on stage. Either way, you want to have everything ready so you're not scrambling when they ask.
Here's what a complete data room includes:
You don't need every single document in this table for every situation. An early-stage room is lighter than a later-stage room. We'll cover that breakdown by use cases a bit further down.
Due diligence is the process where an investor, acquirer, or lender goes through your company in detail before committing. Your data room is how you enable that process without sending 40 email attachments or giving everyone raw access to your Google Workspace.
The due diligence request list you'll typically receive will map to these five areas. Here's what each one actually means in practice.
This is the foundation. These documents prove your company is properly incorporated, equity is cleanly allocated, and there are no legal landmines.
If your equity structure is messy, missing founder agreements, unclear IP assignments, or cap table errors, fix it before opening a data room. People find these things. It's better to know and fix than to have it surface mid-diligence.
This is usually where other parties spend the most time. Everything here should be accurate and internally consistent, meaning your P&L matches your cash flow, which matches what you said in your deck.
Your cap table is the single document most likely to raise a question. Keep it clean and up to date. If you're using a cap table management tool like Carta or Pulley, export the current state before adding it to the room.
IP assignments are the most commonly forgotten document in early-stage rooms. Every business should have signed one at company formation. If they haven't, fix it before diligence starts. This is non-negotiable for most parties.
This section confirms who's actually on board, how they're compensated, and whether key roles are filled.
If you're raising from VCs specifically, the checklist gets slightly more structured than angel-stage diligence. VCs typically run a formal process with a defined request list. Here's what a typical VC due diligence checklist covers, and roughly how each document maps to their decision-making process.
VCs move faster than people expect once they're in diligence. Have everything in the room before you share the link. Don't send a half-built room and say "more coming soon" - that erodes confidence at the worst time.
The depth of your data room should match the stage of the conversation. A seed round data room is lighter than a Series B room. Here's how to think about it.
For a seed round, you don't need 100 documents. A well-organized room with 20-30 accurate documents beats a bloated room with 80 outdated ones. Quality over quantity.
These are the documents you need to load into your VDR before opening the Q&A module. When bidders ask questions, you need to answer fast, meaning everything should already be in the room.
Selling a property or portfolio to investors means putting every document they'd want to see in one place, from the physical building details to the financial returns.
During an IPO, your data room is shared with underwriters, legal counsel, and regulators. Everything in it will be scrutinized. Accuracy and completeness are not optional.
Law firms and in-house legal teams need a secure, organized way to store and share sensitive documents. This checklist covers what belongs in a legal VDR, whether for a matter, a client, or a department.
When two companies collaborate, both sides need to share sensitive information while protecting their own. The VDR has to be structured so each party sees only what they're supposed to.
A data room with 60 unorganized files is almost as bad as no data room. The other parties are probably looking through a lot of rooms. If yours is clean and logical, it signals the same about how you run the company.
Here's a folder structure that works for most data rooms:
01_Company overview
└─ Pitch deck (latest)
└─ Executive summary
└─ One-pager
02_Financials
└─ P&L 2022-2024
└─ Balance sheet (current)
└─ Cash flow statement
└─ Financial model (3-year)
└─ MRR tracker
03_Legal and corporate
└─ Certificate of incorporation
└─ Bylaws
└─ Board meeting minutes
└─ Prior financing docs (SAFEs)
04_Cap table and equity
└─ Cap table (current)
└─ Option pool summary
└─ Vesting schedules
05_Intellectual property
└─ IP assignment agreements
└─ Patent filings
└─ Trademark registrations
06_Customers and commercial
└─ Key customer contracts
└─ Revenue by customer
└─ Churn and retention data
07_Team
└─ Org chart
└─ Founder bios and LinkedIn
└─ Key employment agreements
08_Product and technology
└─ Product roadmap
└─ Tech stack overview
└─ Security and compliance docs
A few naming rules that save time: use dates in file names where relevant ("P&L_2022-2024" not "financials_final_v3"), number your folders so they stay in order, and don't use abbreviations that only make sense internally.
People often over-share. Some documents create more risk than they're worth including, especially early in a conversation. Others are just unnecessary noise.
The rule of thumb: if sharing a document creates risk without meaningfully advancing the conversation, don't include it until the deal is further along.
Once you know what documents go in your data room, you need a place to actually put them. Here's how Ellty fits into this.
Ellty is a virtual data room and secure file sharing platform built for all teams. It's not trying to be an enterprise M&A tool, it's designed to help you share sensitive documents securely, track engagement, and move faster during a deal.
You can set up a room in under an hour. No onboarding calls. No contract. No per-user fees eating into your budget as your visitor list grows.
Ellty works well when you need to share a core set of documents like a pitch deck, financial model, and supporting materials with multiple stakeholders in a structured way. The analytics are especially useful: seeing when a document was opened, how long someone spent on it, and which sections held attention gives you real signals to guide follow-ups.
It’s less suited to highly complex M&A transactions that require built-in Q&A modules, project management layers, or deeply customized enterprise security workflows. For most lean, fast-moving processes, that level of complexity isn’t necessary anyway.
This is where Ellty is different from just uploading files somewhere. When you share a data room link, you can see who accessed it, which documents they opened, which pages they spent the most time on, and when they came back.
If a viewer spent 18 minutes on your financial model and two seconds on the team page, that tells you something. You know exactly what to address on the follow-up call. That kind of signal is the difference between a reactive pitch process and a confident one.
Real-time notifications mean you know when someone is actively in your room, not three days later when you follow up and they've already moved on to something else.
Stop guessing which visitors are actually serious. Set up a trackable data room on Ellty and see exactly who's engaging with your documents - start free, no credit card needed.
A data room is a secure online space where you store and share confidential company documents with investors, acquirers, or legal teams. Think of it as a controlled filing cabinet that tracks who accesses what, with features like NDA gating, access permissions, and document watermarking that normal cloud storage doesn't have.
The core documents are: corporate formation papers, financials (P&L, balance sheet, cash flow, financial model), cap table, IP assignments, key customer contracts, employment agreements for key people, and your pitch deck.
A due diligence request list (sometimes called a diligence checklist or DDQ) is a document an investor or acquirer sends you listing every document and piece of information they need before closing a deal. Your data room is where you fulfill that request. Having your data room organized in advance means you can respond in hours instead of days.
Yes, but it doesn't need to be elaborate. At seed stage, a clean room with your pitch deck, basic financials, cap table, certificate of incorporation, SAFE documents, IP assignments, and founder bios is usually enough. The key is having it ready before an investor asks, not scrambling to build it mid-conversation.
Google Drive is file storage. A data room is a secure sharing environment. Drive doesn't give you view analytics, NDA gating, watermarking, granular access permissions, or audit logs. For sharing sensitive financial and legal documents with external parties, those missing features create real gaps, especially if a deal falls through and you want to revoke access.
NDA gating means that before anyone can access your data room, they must read and digitally accept a non-disclosure agreement. It's automated, you don't have to chase signatures manually. Ellty Data Room plan includes NDA gating as a built-in feature.
Dynamic watermarks automatically overlay each document with the viewer's name, email, and a timestamp. If someone screenshots or forwards a page, the watermark travels with it and identifies exactly who had access. This is a strong deterrent against unauthorized sharing of sensitive documents.
Pricing varies significantly. Enterprise platforms like Intralinks or Datasite don't publish pricing - expect $1,000-$3,000+ per month for large M&A deals. For most businesses, flat-rate platforms are more practical. Ellty offers a free plan for basic document tracking and secure sharing, with the core data room plan (NDA gating, granular permissions, watermarking) at $149/month with no per-user fees.
A pitch deck is a short visual presentation you use to generate visitor interest. A data room is a comprehensive document collection you share during due diligence. You share the deck first. You share the data room once a party is seriously interested. They serve different purposes at different stages of the process.
