You're in the middle of fundraising or preparing for an acquisition. A potential acquirer or investor says they're ready to start due diligence. Then comes the inevitable question: where do you want to share documents?
If your answer is 'a Google Drive folder,' you probably don't have a data room yet.
This guide explains what a virtual data room is, when you actually need one, how to pick the right provider, and what good due diligence preparation looks like in practice. No fluff, no unnecessary upsell.
What is a virtual data room?
A virtual data room (VDR) is a secure online repository used to store and share confidential documents during business transactions. It's the digital successor to the physical 'data room' - a locked room in a law firm or bank where both parties would physically review documents during M&A deals.
Today, a VDR gives you a controlled environment where you decide who sees what, for how long, and with what level of access. You can track every action: who opened a document, which pages they read, how long they spent on each section. You can revoke access at any time.
In the context of M&A, a virtual data room is where you share financial records, legal documents, IP, customer contracts, and other sensitive materials with potential buyers, acquirers, or their legal teams - without losing control over your confidential information.
Setting up a data room doesn't have to take weeks. Ellty lets you create a secure data room in minutes.

Why Google Drive won't cut it for M&A
Google Drive is fine for internal collaboration. It's not built for due diligence. Here's the practical difference:
The issue isn't just security. It's control and accountability. In M&A, you need to know who is looking at what and when. You also need to prove - to your lawyers, your board, and yourself - that sensitive data was handled appropriately throughout the process.
When do you actually need a virtual data room?
Not every startup needs a dedicated VDR. Here's when it makes sense to invest in one:
- You're raising a Series A or later round and investors want formal due diligence
- You're in active M&A conversations - acquisition, merger, or a strategic investment
- You're going through a secondary transaction or investor exit
- You need to share sensitive IP, contracts, or financial data with multiple parties at once
- You want documented proof of what was shared and when, for legal protection
For pre-seed or seed-stage founders sharing a pitch deck with a handful of angels, a full VDR may be overkill. A secure document sharing platform with tracking is probably enough. Once you're in formal due diligence with institutional investors or acquirers, the calculation changes.
What goes into an M&A data room?
Every deal is different, but most M&A data rooms include documents across these categories. Organize them clearly from day one - buyers notice if you haven't.
Don't dump everything in at once. Start with the documents buyers most commonly request in early due diligence, then add depth as the deal progresses. Staged disclosure is standard practice and protects you if talks fall through.

Key features to look for in a virtual data room
There's a lot of noise in VDR marketing. Strip it back and focus on what actually matters for your deal.
Granular access controls
You need to control access at the folder and document level, not just the room level. Different parties (legal, finance, technical) should see only what's relevant to them. Look for role-based permissions and the ability to restrict printing, downloading, or copying.
Audit logs and activity tracking
A full audit trail is non-negotiable. You should be able to see every document viewed, by whom, on which date, for how long. This protects you legally and gives you intelligence about where buyers are spending their time.
NDA gating
Require users to accept an NDA before they can view any documents. Some VDRs let you customize the NDA text. This is a basic legal protection you shouldn't skip.
Dynamic watermarking
Watermarks that display the viewer's name and email on every page. Discourages screenshots and leaks. Essential if your documents contain sensitive financial projections or unreleased IP.
Document analytics
Beyond who viewed what, good VDRs tell you which pages were read most, which sections were skipped, and where viewers spent the most time. This is real signal. If a buyer's team spent 40 minutes on your customer contracts but skipped the financials, that tells you something.
Q&A and communication tools
Enterprise VDRs often include built-in Q&A workflows where buyers can submit questions and you respond in a structured way. This keeps communication organized and creates a record. Less critical for early-stage deals, but useful in complex transactions.
Fast setup and ease of use
You'll probably be setting this up while managing a hundred other things. A VDR that takes days to configure isn't helping you. Look for drag-and-drop uploads, bulk permissions, and a clean interface that your lawyers and counterparties won't complain about.
Virtual data room providers: a practical comparison
Here's a breakdown of the main virtual data room providers and where they fit. Pricing is approximate and changes frequently - always check directly with vendors.
Enterprise platforms like Datasite and Intralinks are built for billion-dollar transactions managed by investment banks with dedicated deal teams. If you're a Series A startup preparing for your first institutional fundraise or a potential acquisition, you don't need that level of complexity or cost.
Ellty sits in a different category. It's built for founders who need a functional, secure data room with document analytics - without per-user fees that make costs unpredictable as more people join the deal. You can set up a data room, gate it with an NDA, and share a link the same day.
Virtual data room pricing: what to expect
VDR pricing is one of the least transparent areas in SaaS. Most enterprise providers quote based on deal size, storage, and number of users. Here's how to think about costs before you commit.
Ellty uses flat-tier pricing with no per-user charges on data room plans. The Data Room plan ($149/month) includes 3 users, granular permissions, NDA gating, dynamic watermarking, and restricted visitor access. The Data Room Plus plan ($349/month) adds group visitor permissions, audit logs, and up to 4,000 assets per data room.
If you're comparing, calculate total cost based on your expected deal timeline and the number of people likely to access the room - not just the headline monthly rate.
Avoid per-user pricing surprises. Ellty data room plans include everything you need at a flat monthly rate, for 3 team members.
How to set up a virtual data room for M&A
Setting up a VDR doesn't have to be complicated. Here's a step-by-step process that works for most startup M&A situations.
Virtual data room security: what actually matters
Security is where VDR marketing gets the most inflated. Every provider claims 'bank-level security.' Here's what to actually verify:
- SOC 2 Type II certification - this is the baseline standard for data handling. Ask for the report, not just the logo.
- ISO 27001 certification - international standard for information security management.
- Data residency - where is your data stored? EU-based companies should check GDPR compliance carefully.
- Encryption - documents should be encrypted at rest (AES-256 is standard) and in transit (TLS 1.2 or higher).
- Access control - MFA, IP restrictions, and session timeouts should be available.
- Uptime and availability - check SLA commitments, especially if you're running a time-sensitive deal.
Don't just take marketing copy at face value. Ask for the actual security documentation. Reputable providers will share it without hesitation.

Common mistakes founders make with data rooms
Seen these patterns over and over. Avoid them.
Uploading everything at once
Don't dump your entire file system into the data room on day one. Start with the standard due diligence materials. Add sensitive documents (cap table details, key customer contracts) only when you're further along in the process. Staged disclosure is not unusual - it's expected.
Not using an NDA gate
Even if you think you can trust the counterparty, an NDA gate protects you legally and creates a formal record of agreement before access is granted. Don't skip it.
Ignoring the analytics
Your VDR analytics are real intelligence. If a buyer's team spends an hour on your customer churn data and asks no questions, that's a signal. If they haven't opened your financial model after two weeks, follow up. Use the data.
Sharing the same link with everyone
Different stakeholders need different access. Your potential acquirer's legal team doesn't need to see what your financial advisor is looking at. Set up separate access groups from day one.
Not keeping the data room clean
Outdated documents create confusion and can raise red flags. If your financial model from 18 months ago is sitting next to last month's version, a buyer will notice. Keep it organized and version-controlled.
Virtual data room example: what a clean setup looks like
Here's a simplified example of how a Series B startup might structure their data room for an M&A process:
This structure lets you give different access levels to different groups without needing to manually manage every document. The buyer sees what they need at each stage. Sensitive HR and legal details are restricted. You're in control throughout.
How Ellty document analytics change the fundraising game
Beyond data rooms, Ellty core functionality is document-level analytics for pitch decks and investor materials. This matters more than most founders realize.
When you share a pitch deck via email, you have no idea what happens next. Did they open it? Did they get to slide 12? Did someone forward it internally? You're in the dark.
With Ellty trackable links, you can see exactly who opened your deck, which slides they spent time on, which ones they skipped, and when they shared it with a colleague. You get a real-time notification the moment someone views your document.
This isn't just vanity data. It's actionable intelligence. If an investor reads your deck twice but hasn't replied to your follow-up email, you know they're interested. If they stopped at slide 4, you might have a problem with your early narrative. You can tailor your follow-up accordingly.
Know exactly who's reading your pitch deck and which slides they care about. Create a trackable link on Ellty - it's free.
FAQ: virtual data rooms for M&A
What is a virtual data room in M&A?
A virtual data room is a secure online platform used during M&A due diligence to share confidential documents between buyers, sellers, and their advisors. It replaces physical document rooms and gives the seller control over who accesses what, with full audit logging.
What is the best virtual data room for M&A?
There's no single best option - it depends on deal size and complexity. Enterprise deals often use Datasite, Intralinks, or Ansarada. For startups and mid-market deals, providers like Ellty, Digify, and Firmex offer solid functionality at a lower cost. Ellty is a strong fit if you want fast setup, document analytics, and flat pricing without per-user fees.
How much does a virtual data room cost?
Prices range from around $69/month for basic document sharing platforms to $500+/month for enterprise VDRs. Ellty's Data Room plan starts at $149/month with NDA gating, dynamic watermarking, and granular permissions. Enterprise providers like Datasite typically price by deal and can cost several thousand dollars per transaction.
What documents go in an M&A data room?
Typically: corporate structure documents, financial statements, legal contracts, IP documentation, employee agreements, customer contracts, and tax records. Exact requirements vary by deal type. Your legal advisor or the buyer will usually provide a due diligence checklist.
How long does it take to set up a virtual data room?
With modern platforms, the technical setup takes less than an hour. The real time investment is organizing and uploading your documents. Most founders underestimate this part. If your documents are well-organized internally, you can have a functional data room ready in a day or two.
Is Google Drive secure enough for M&A due diligence?
No - not for formal due diligence. Google Drive lacks NDA gating, page-level view tracking, dynamic watermarking, and granular audit logs. It's fine for internal collaboration, but it's not designed to give you the legal protection and document intelligence you need in an M&A process.
Can I use a virtual data room for fundraising, not just M&A?
Yes. VDRs are increasingly used for Series A and later fundraising rounds, not just acquisitions. Investors often request formal due diligence access even before term sheets. Ellty is built for both use cases - secure data rooms for due diligence and trackable pitch deck sharing for earlier-stage investor conversations.
What security certifications should a virtual data room provider have?
Look for SOC 2 Type II and ISO 27001 as the minimum. Also check that data is encrypted at rest and in transit, that MFA is available, and where your data is physically stored. If you have GDPR obligations, make sure the provider offers EU data residency or is compliant.
What is a virtual data room example for a startup?
A typical startup data room for a Series B fundraise or acquisition would include folders for: corporate documents, financials (3 years plus forecast), legal contracts, IP, key employee agreements, customer contracts, and tax records. Access is split by audience group - the buyer's legal team gets different permissions than their commercial team. View activity is tracked throughout.
How is Ellty different from other virtual data room providers?
Ellty combines pitch deck analytics with data room functionality in a single platform. It's built for founders, not investment bankers. Setup is fast, the interface is clean, and pricing is flat - no per-user fees that add up when multiple stakeholders join the process. It's positioned for startups and growth-stage companies, not billion-dollar M&A transactions.
Final word
A virtual data room isn't just a place to dump documents. It's how you control your narrative during one of the most high-stakes processes you'll go through as a founder. The right setup protects you legally, gives you deal intelligence, and signals to buyers and investors that you're organized and serious.
You don't need to spend thousands a month on enterprise software to achieve that. For most startup deals, a well-organized data room on the right platform is entirely sufficient.
If you're starting from scratch, set up an Ellty data room today. Upload your pitch deck, create a trackable link, and see what your investors are actually reading. It's free to start, and you can upgrade to a full data room plan when you're ready to go deeper into due diligence.
