Series A data rooms: what they are, what they cost, and what to use

A practical guide to what a data room is, what goes in it, how much it costs, and which tools are actually worth your time when you're raising.

What is a virtual data room?

A virtual data room (VDR) is a secure online space where you store and share sensitive business documents with a specific group of people - typically investors, lawyers, or acquirers. Think of it as a locked digital filing cabinet with a visitor log.

Unlike a shared Google Drive folder, a proper data room lets you control exactly who sees what, track every document view, set document-level permissions, add watermarks, and revoke access any time. Some let you set up NDAs that visitors must accept before they can see anything.

VDRs became standard in M&A transactions years ago. Now they're increasingly common in venture fundraising, especially at Series A and beyond, where investors start doing real due diligence.

What is Series A in venture capital?

Series A is typically the first significant institutional round of funding a startup raises - usually after a seed round has helped you prove some early traction. At this stage, you're going to professional venture capital firms, not just angels and accelerators.

The median Series A in the US in 2024 was around $10-15M, though ranges vary a lot by sector and geography. What matters more than the number is what investors expect from you at this stage.

At seed, investors often bet on the team and the idea. At Series A, they want evidence. Revenue growth, retention, unit economics, a clear path to scale. And they'll do due diligence - which means they'll want to see your documents, not just your slides.

Why you need a data room for Series A

Series A investors move fast when they're interested - and they stop moving entirely when the process feels disorganized. A data room solves both problems.

Here's what happens without one. An investor asks for your financials. You email a spreadsheet. Two weeks later, their associate asks for the same spreadsheet plus your cap table. You send another email. Then legal gets involved and asks for the same files again. You spend hours tracking down documents, sending updated versions, and wondering who has what.

With a data room, you send one link. Everything is there. You can see who opened it and what they looked at. When they come back with questions, you already know which sections they studied.

There's also a perception angle you shouldn't ignore. Showing up to a Series A process with a well-organized data room signals operational maturity. It tells the investor you've done this before, or at least that you prepared properly.

You don't set up a data room after term sheet. You set it up before you start reaching out to investors, so you're ready the moment someone says "send me your materials."

What goes in a Series A data room?

The exact contents depend on your business, but most Series A data rooms cover the same core categories. Here's a practical checklist.

Company overview

• Pitch deck (latest version)
• Company overview or one-pager
• Product demo video or link
• Press coverage or notable mentions

Financials

• Historical P&L (2-3 years or from founding)
• Balance sheet
• Cash flow statements
• Financial model with projections (3-5 years)
• MRR/ARR breakdown and growth chart
• Unit economics (CAC, LTV, payback period)

Legal and corporate

• Certificate of incorporation
• Cap table (usually via Carta or similar)
• Previous funding documents (SAFEs, convertible notes, prior term sheets)
• Shareholder agreements
• Key IP registrations (patents, trademarks)

Team

• Org chart
• Founder bios
• Key employee agreements
• Advisory board (if relevant)

Product and tech

• Product roadmap
• Tech stack overview
• Security and compliance documentation (SOC 2, GDPR, etc.)
• Key metrics dashboard or data export

Customers and market

• Customer list (anonymized is fine for sensitive industries)
• Key customer contracts (redacted if needed)
• NPS or customer satisfaction data
• Market sizing analysis
• Competitive landscape

Don't put everything in at once. Start with what you have, organize it clearly, and expand as the process progresses. A tidy data room with 25 documents beats a messy one with 80.

How to set up a virtual data room

Setting up a data room doesn't have to be complicated. Here's a practical process that works whether you're using a dedicated tool or a simpler platform.

Step 1 - Choose your tool

Pick a platform before you start gathering documents. Trying to migrate files mid-process is painful. Consider what you actually need: secure sharing, document tracking, permissions control, NDA gates, watermarking.

Step 2 - Create your folder structure

Use the categories from the previous section as your template. Keep folder names clear and consistent. Investors shouldn't have to hunt for your financials.

Step 3 - Upload your documents

Start with what you have. Don't delay the process waiting for a perfect model or updated deck. Placeholder folders ("coming soon") are better than sharing an unorganized drive link.

Step 4 - Set permissions

Decide who gets access to what. A common approach: a "teaser" view for early-stage conversations (overview + deck only), and a "full access" view for investors who are deeper in the process. Don't give everyone everything on the first contact.

Step 5 - Configure security settings

At minimum, enable viewer tracking. If you're sharing sensitive financials or contracts, enable watermarking and consider adding an NDA gate so visitors must accept terms before accessing documents.

Step 6 - Test before you share

Open the link yourself in an incognito browser. Check that files load correctly, the folder structure makes sense, and your permissions are working as intended.

Step 7 - Share and monitor

Send the link. Then actually check your analytics. Knowing an investor opened your deck three times and spent 12 minutes on your financial model is useful context for your next call.

How much does a virtual data room cost?

Virtual data room pricing varies enormously depending on the type of product you're looking at. Enterprise VDR software built for M&A transactions can run $400-$2,000+ per month. That's designed for law firms and PE shops running dozens of deals simultaneously - overkill for a startup raising a single Series A.

For startup use cases, there are more sensible options:

A few things to watch for in pricing:

• Per-user fees - some platforms charge per invited viewer, which adds up fast when you're sharing with 20 VCs
• Per-page or per-document fees on older enterprise tools
• Storage overages if you have a lot of large files
• Annual-only contracts that lock you in before you know if the product works for you

For a typical Series A process - a few months, 20-40 investor contacts, a few hundred documents - you probably don't need to spend more than $150-200/month. Enterprise pricing is for enterprise use cases.

Best data room tools for startups

There are a lot of options in this category. Here's an honest overview of the main tools founders actually use.

Dedicated VDR platforms

Tools like Digify, Firmex, Intralinks, and Datasite are purpose-built for secure document sharing. They tend to have more advanced security features - granular permissions, audit logs, watermarking, Q&A modules. The tradeoff is cost and complexity. Most are priced for M&A, not seed-to-Series-A fundraising.

Google Drive + permissions

Technically free and you probably already use it. The problem: no proper audit trail, no NDA gating, no document-level analytics, no watermarking. It works for casual sharing but it's not really a data room. Investors know the difference.

Notion or Confluence

Some founders use these for internal documentation and share a public view for early conversations. Again, not really a data room - no security controls, no tracking, no access expiry.

DocSend

Popular with founders for pitch deck sharing. Good analytics, link-based sharing, decent security. Pricing starts around $45/month for basic plans and scales up for team features and data room functionality.

Ellty

Ellty positions itself as a pitch deck sharing, analytics, and data room platform built for founders. It offers document tracking, real-time analytics (who viewed, which pages, time spent), secure data room features, NDA gating, dynamic watermarking, granular permissions, and audit logs depending on plan. More on this in the next section.

How Ellty fits into the picture

Ellty is built for founders who need to share pitch decks and documents securely, track engagement, and manage a due diligence process without buying enterprise software.

Here's what the plans actually include, so you can decide if it fits your situation:

A few things worth noting honestly:

Ellty works well when you're a startup running a Series A process and need to share a pitch deck, financial model, and a set of due diligence documents with investors. The analytics are particularly useful - knowing an investor opened your deck at 11pm and spent seven minutes on your revenue chart is the kind of signal that shapes how you prepare for the follow-up call.

Ellty is less suited to extremely complex M&A transactions that require features like Q&A modules, dedicated project management within the data room, or highly customized enterprise security workflows. For a startup raising a Series A, that's probably not what you need anyway.

One practical advantage: Ellty doesn't charge per viewer. When you're sharing with 30 investors, per-user pricing from other platforms adds up quickly. Ellty offers data room features without per-user pricing on investor access.

Setup is fast. You can go from signup to a shared, trackable link in under 15 minutes. For founders who've spent weeks configuring enterprise VDR tools, that difference is noticeable.

Free data room options for startups

If you're pre-seed or just starting to explore fundraising, you probably don't need to pay for a data room yet. Here are the realistic options:

Ellty free plan

Gives you document tracking and real-time analytics at no cost. You can see who viewed your documents and which pages they spent time on. It's a solid starting point before you need the full data room feature set.

Google Drive (free tier)

Works for basic document sharing but doesn't give you analytics, access control, or security features. Use it for internal organization, not investor sharing.

Notion public pages

Good for a lightweight "about us" page or early investor update hub. Not appropriate for sensitive financial documents.

What "free" actually means

Most free plans have meaningful limitations. Ellty free plan gives you tracking and analytics, which is genuinely useful. But NDA gating, watermarking, and granular permissions are paid features. That's a fair tradeoff - use free to get started and validate the tool, upgrade when the process gets serious.

If an investor is doing real due diligence on a $5M+ check, you should probably be on at least the $149/month Data Room plan. The cost over a 3-month raise process is trivial compared to what's at stake.

Frequently asked questions

What is a virtual data room?

A virtual data room is a secure online platform for storing and sharing sensitive business documents with selected parties. Unlike cloud storage, it includes access controls, document tracking, audit trails, and security features like watermarking and NDA gating. They're commonly used for fundraising due diligence, M&A transactions, and legal processes.

Do I really need a data room for Series A?

Yes, practically speaking. Institutional investors at Series A will request documents, and managing that process over email is messy and unprofessional. A data room keeps everything organized, shows you who's engaged, and signals that you run a tight operation. It's also useful after the raise - you'll already have organized documentation for your board and future rounds.

What is Series A in venture capital?

Series A is typically the first formal institutional funding round for a startup, usually following a seed round. It involves raising from professional VC firms, typically in the $5M-$20M range, and comes with full due diligence. Investors at this stage want to see revenue traction, unit economics, team, and a credible path to scale - not just an idea.

How much does a virtual data room cost?

It depends heavily on the type of product. Enterprise M&A platforms can cost $500-$2,000+ per month. Startup-focused tools range from free to around $350/month. Ellty Data Room plan starts at $149/month, which covers NDA gating, watermarking, granular permissions, and viewer tracking - enough for most Series A processes.

How do I set up a virtual data room?

Choose your tool, create a folder structure based on the standard categories (company overview, financials, legal, team, product, customers), upload your documents, configure permissions and security settings, test the access link yourself, then share it with investors. The whole setup process can take 2-4 hours if your documents are already organized.

Is there a free data room for startups?

Yes. Ellty offers a free plan with document tracking and real-time analytics. Google Drive is free but lacks proper data room security features. For early-stage conversations, a free tier can work. For actual due diligence with a serious investor, the security and permission controls in a paid plan are worth having.

What documents go in a Series A data room?

The core categories are: company overview (pitch deck, one-pager), financials (P&L, financial model, MRR breakdown, unit economics), legal and corporate (incorporation docs, cap table, prior funding docs), team info, product and tech documentation, and customer data. You don't need everything on day one - start with the essentials and expand as the process deepens.

What's the difference between a data room and Google Drive?

The main differences are tracking, security controls, and access management. Google Drive doesn't tell you who viewed a file, for how long, or which pages they looked at. It doesn't support watermarking, NDA acceptance, document-level permissions, or audit logs. A data room provides all of this. For sharing sensitive startup documents with investors, that gap matters.

When should I set up my Series A data room?

Before you start outreach. The worst time to set one up is when an interested investor asks for documents and you're scrambling. Aim to have a functional data room - even a lightweight one - ready before your first investor meeting. You can always add documents as the process progresses.

Does Ellty support NDA gating and watermarking?

Yes, both are available on the Data Room plan ($149/month). NDA gating requires visitors to accept a non-disclosure agreement before accessing documents. Dynamic watermarking overlays the viewer's information on documents to discourage unauthorized sharing. These features aren't available on the free or Standard plans.

How is Ellty different from DocSend?

Both offer document tracking and analytics for pitch deck sharing. Key differences include: Ellty doesn't charge per viewer (DocSend charges per seat on most plans), Ellty includes NDA gating and watermarking on its Data Room plan, and Ellty has a free tier with real analytics. DocSend is a well-established product with a strong reputation for pitch deck sharing. Ellty works well for founders who want data room features without the per-user cost structure.

The bottom line

A virtual data room isn't complicated. It's a secure, organized place to share documents with investors during due diligence. For a Series A process, you need one - the question is which tool fits your situation and what you're willing to spend.

If you're early-stage and want to start tracking pitch deck engagement without spending anything, Ellty free plan is a practical starting point. If you're actively running a Series A or a Series B, and sharing sensitive financial and legal documents, the Data Room plan at $149/month gives you the security and control features that actually matter.

Set it up before you need it. Keep it organized. Use the analytics. And stop emailing documents to investors who may or may not open them - that's information you should have.
