You're raising a round and someone told you to get a data room. You found SeedLegals, which handles UK startup legals and has a data room built in. Now you're wondering: is the data room actually good enough, or do you need something else?
That's the right question. SeedLegals is a powerful platform for UK startup legals - SEIS/EIS, funding rounds, cap tables, employment agreements. The data room is a feature inside that platform, not a standalone product. This guide breaks down exactly what it does, what it costs, where it falls short, and when a dedicated alternative makes more sense. Ellty is one option worth knowing about - a standalone data room with transparent pricing from £0.
A virtual data room (VDR) is a secure online repository for storing and sharing confidential documents during fundraising, due diligence, or other sensitive transactions. Unlike basic file sharing, a data room gives you control over exactly who sees what. You can track who accessed documents and when, set permissions by user group, and revoke access instantly.
Investors and lawyers expect data rooms for anything beyond a casual intro. If you're closing a SEIS/EIS round, doing Series A diligence, or managing an acquisition, you'll need one. A data room tells investors you're organized. It also protects you - sensitive financials and contracts shouldn't live in email chains or open Google Drive folders.
SeedLegals launched their Data Room feature as part of their all-in-one UK startup legals platform. It's not a standalone product - it lives inside your funding round workflow, your pitch page, and your board management tools. The platform has helped over 60,000 UK companies raise more than £2.5 billion.
There are actually three distinct data room contexts within SeedLegals: the Pitch Data Room (linked to your public pitch page for sharing materials with prospective investors), the Deal Data Room (inside an active funding round for due diligence documents), and the Board Data Room (for governance materials shared with directors). Each serves a different stage of your company's growth.
The data room integrates directly with SeedLegals' document creation tools, meaning the legal documents you generate on the platform (Term Sheets, Shareholders Agreements, Articles, etc.) automatically appear in the relevant data room. You don't need to download and re-upload your own legal documents.
Who uses it:
SeedLegals offers several ways to share documents: a public pitch page, a deal data room inside a round, and a board data room. Here's how they differ and when each makes sense.
When to use the SeedLegals pitch page: You're early in conversations. Investors want a high-level view of your company. You're not ready to share sensitive documents. Setup speed matters.
When to use the SeedLegals data room: You have serious investors who want to run due diligence. You need to share founder agreements, employment contracts, IP documents, and financial forecasts. You want to control who sees what and track their engagement.
The key difference: The pitch page is for opening conversations. The data room is for closing them. You'll likely use both during a funding round.
Setting up the SeedLegals data room is straightforward if you're already using the platform for your funding round. It's designed to be self-service without needing DFIN-style onboarding calls or weeks of implementation.
Step 1: Get on an active plan You need at least an Access plan (£75/month or £590/year) to access the full data room features. The Deal Data Room specifically requires an open funding round on the platform.
Step 2: Open a funding round Navigate to Raise > Funding Round. Start a new round and enter your round details. SeedLegals will begin generating the legal documents you need (Term Sheet, Shareholders Agreement, etc.) which auto-populate the Documents tab.
Step 3: Find your Deal Data Room Inside your funding round, click the Documents tab. At the top you'll see your SeedLegals-generated documents. Below that is your Deal Data Room - the upload area for your own supporting documents.
Step 4: Upload your supporting documents Upload the materials investors will need for due diligence. Drag and drop works. You can add more at any time. Common uploads include founder service agreements, employment contracts, IP assignments, financial forecasts, and business plans.
Step 5: Set up investor groups Navigate to the Groups tab in your funding round. SeedLegals creates an "All investors" dynamic group by default - every investor you add to your round is automatically included. You can also create custom groups for specific stages, e.g. "Lead investors and lawyers" vs "Potential investors."
Step 6: Share with investors Assign document access to the relevant groups. When you add a new investor to your round, they automatically get access to any documents assigned to "All investors." When an investor pulls out, remove them from the round and their access is revoked instantly.
Step 7: Manage access as the round progresses Add documents as they become ready. Adjust groups as investors move through stages. Track who has accessed what through the platform.
Total setup time: 30-60 minutes for a standard seed round with organized documents. Add time for preparing documents that need to be uploaded (service agreements, signed contracts, financial models).
Ongoing maintenance: Low effort if you use SeedLegals for your round legals. Documents generated on the platform appear automatically. You just need to upload supporting third-party documents and manage investor group access as the round evolves.
The data room is included in all SeedLegals paid plans at no additional charge. There are no per-user fees, no storage add-ons, and no data room-specific pricing. You pay for the SeedLegals platform membership, and the data room comes with it.
That said, the Deal Data Room specifically requires an open funding round, which costs extra beyond the base subscription (more on that below).
Access plan - £75/month or £590/year + VAT
The entry-level paid plan. You get the Pitch Data Room (linked to your investor pitch page) and the Board Data Room. Full cap table, essential contracts, legal document creation, and board management tools included. To use the Deal Data Room inside a funding round, you'll need to purchase the actual funding round product separately.
Start / Raise / Scale plans - £1,490-£4,990/year + VAT
These are the plans most founders raising capital will actually use. They bundle the Access plan features together with "Flex credits" - credits you spend on actual transactions like funding rounds, SeedFASTs, and share transfers. The difference between tiers is how much Flex you get (i.e., how much you can raise per year before buying more). All include full data room access with no additional cost. These replaced the older "Standard" and "Plus" plan naming.
Funding round cost (Deal Data Room requirement)
The Deal Data Room is unlocked when you open a funding round. A Seed & Series A round costs £1,990 + VAT as a Flex spend. On the Start plan, this Flex is included up to £100k raised. On the Raise plan, up to £250k. So if you're on the Access-only plan and want a full Deal Data Room, budget for the round cost on top.
Beyond base subscription:
Round costs: If you're on the Access plan (£590/year), running a full funding round is an extra £1,990 + VAT in Flex credits. That brings your total to roughly £2,580 + VAT minimum for a year with one round - similar to the Start plan at £1,490/year which bundles it.
VAT: All SeedLegals pricing is + VAT (20%). The £590/year Access plan is actually £708/year all-in. Factor this into your budget comparisons.
SEIS/EIS: If you need Advance Assurance, that's £390 + VAT separately. Compliance is from £490 + VAT. These aren't included in base plans and aren't part of the data room, but they're costs most SeedLegals users encounter.
Storage limits: SeedLegals doesn't publish explicit storage caps. The platform is designed for legal documents and financial files - not bulk media or massive data sets. For typical fundraising document sets this isn't an issue, but it's worth knowing there's no stated unlimited storage guarantee.
Document limitations: Some users have noted the data room lacks folder organization (sub-folders). You're working with a flat document list within groups, not a hierarchical folder tree. For complex due diligence with dozens of document categories, this is a real constraint.
Early-stage founder raising a pre-seed SEIS round (3 investors)
You join on the Start plan at £1,490 + VAT/year (£1,788 all-in). This includes everything - legals, cap table, data room, and Flex credits for your round up to £100k raised. No separate data room fee. No per-investor fee. Total annual cost for the full stack: £1,788.
Seed stage founder raising £300k with multiple investors
You'd need the Raise plan at £2,790 + VAT/year (£3,348 all-in), which covers up to £250k Flex, meaning the first £250k raise is included. You'd buy additional Flex for the remaining £50k. Data room access included throughout. No extra cost per investor or per document.
Founder who only needs a data room (no SeedLegals round)
This is where it gets tricky. If you don't need SeedLegals' legal services and just want a data room, the Access plan at £590/year + VAT gives you the Pitch and Board Data Rooms. The Deal Data Room requires an active round. Paying £590+/year for a data room feature alone is hard to justify when standalone options exist at a fraction of that cost.
SeedLegals is reasonably priced when you're using the full platform for UK startup legals. If you only want a data room, you're paying for a lot of features you won't use.
Data rooms aren't always necessary. Here's when they add real value, and how SeedLegals' version fits each scenario.
The scenario: You're raising your first or second round from UK angel investors. Some have SEIS/EIS questions. Others want to see your founder agreements and financial model before committing. You're managing three to ten investors simultaneously, each at different stages of their decision.
Why a data room helps:
What you'd include:
Example workflow: Open a SeedLegals round and begin generating legal documents. Upload supporting materials to the Deal Data Room. Add investors as they express interest - they automatically get access to the "All investors" group documents. Create a separate "Lead investors" group with access to more sensitive materials like full financials. Track who's reviewed what and prioritize conversations accordingly.
SeedLegals features that matter:
The scenario: UK investors want SEIS or EIS relief. That means they (and HMRC) need specific documentation confirming your company meets the qualifying conditions. Lead investors often conduct structured due diligence before signing, covering legal, financial, and operational aspects of the business.
Why a data room helps:
What you'd include:
Example workflow: Generate your SEIS/EIS Advance Assurance through SeedLegals (£390 + VAT). Upload the approval letter and supporting documents to your Deal Data Room. Share with potential investors who can review documentation to confirm eligibility. For investors using lawyers, add the lawyer to a "Lead investor - legal" group with full document access.
SeedLegals features that matter:
The scenario: You're raising Series A from institutional VCs. The due diligence process is more structured and extensive than seed. Lead investors will send a formal due diligence checklist covering legal, financial, commercial, technical, and HR dimensions. Multiple people on their team will access materials simultaneously.
Why a data room helps:
What you'd include:
Example workflow: Build a comprehensive data room before starting investor conversations. Organize by due diligence category using SeedLegals' groups feature. Start with limited access for initial conversations. Expand to full due diligence access once term sheet discussions progress. Coordinate with your lawyers on what to include in which group.
SeedLegals features that matter:
A note on Series A: SeedLegals' data room works for Series A, but it's worth knowing the interface is optimized for seed-stage simplicity. Very large document sets or complex multi-party processes may benefit from a more feature-rich VDR. Assess based on your specific round complexity.
The scenario: You have a board of directors including external investors and independent directors. They need regular access to board packs, minutes, management accounts, and strategic documents. You want a secure, organized way to share these without emailing PDFs every quarter.
Why a data room helps:
What you'd include:
Example workflow: Use the SeedLegals Board Data Room (included in all plans). Add board members as users. Upload board pack before each meeting. Share minutes after sign-off. Maintain a running archive that all board members can access anytime. SeedLegals' board management tools also help with agenda creation and meeting minutes templates.
SeedLegals features that matter:
The scenario: You're not formally raising yet. But you're building relationships with potential angels or advisors who want to understand the business before you open a formal round. You want to share some materials without the full due diligence structure of a live round.
Why a data room helps:
What you'd include:
Example workflow: Use the Pitch Data Room linked to your SeedLegals pitch page. Upload supporting documents. Share the pitch link with specific individuals. They'll see your pitch page and can request access to data room materials. Track who views your pitch and which materials they access.
SeedLegals features that matter:
The scenario: Your round has closed. You now need to keep records of all signed documents for future reference - by future investors, your accountants, or potential acquirers. You want everything accessible and organized without managing a file server.
Why a data room helps:
What you'd include:
Example workflow: Leave your SeedLegals account active between rounds. All documents created on the platform are stored and accessible from My Documents. Update your cap table as any changes occur. When you start your next round, prior documents are already available.
SeedLegals features that matter:
SeedLegals is honest that the data room is a feature within a legal platform, not a standalone VDR product. Knowing the constraints upfront saves frustration.
No folder hierarchy This is the most commonly cited limitation from real users. SeedLegals' data room doesn't support nested folders or subfolder structures. You work with flat document lists organized by group. For a seed round with 20-30 documents, that's fine. For a Series A with 100+ documents across categories (legal, financial, commercial, HR, technical), it becomes hard to navigate. One Capterra reviewer specifically noted they'd like "grouping documents in folders (e.g. sub-folders)" as an improvement.
Deal Data Room requires an active funding round You can't use the Deal Data Room as a standalone secure document repository. It only exists inside an open funding round on the platform. If your round closes or you cancel your membership, access to documents in that room follows the round lifecycle. This matters if you want an always-on data room separate from your transaction timeline.
Not designed for complex M&A or enterprise due diligence SeedLegals is built for UK startup fundraising. The data room reflects that focus - it's designed for rounds with tens of investors, not for enterprise M&A with hundreds of users, sophisticated permission tiers, or regulatory compliance requirements. Don't try to use it for a £50M+ acquisition or a multi-bidder competitive process.
Limited analytics depth You can track who has viewed your pitch page and which investors have accessed your round. But you won't get the granular document-level analytics that dedicated VDRs provide - things like time spent on specific pages, which document sections attracted attention, or comparative engagement between investors. If investor behavior analytics matter to your follow-up strategy, this is a gap.
No advanced security features SeedLegals provides standard encryption and secure access. It doesn't offer dynamic watermarking on downloaded documents, screenshot prevention, print restrictions, or automatic redaction. For most seed and Series A rounds, standard security is enough. For highly sensitive transactions with sophisticated counterparties, this may fall short.
UK-focused platform SeedLegals is primarily designed for UK companies and UK legal frameworks (English law, SEIS/EIS, Companies House). If you're a non-UK company or raising from primarily US investors expecting US legal structures, the platform's value proposition diminishes significantly and the data room context won't match their expectations.
Data room access requires paid membership There's no free plan. The 7-day free trial lets you explore the platform, but you'll need a paid plan to use the data room in any meaningful way for investor sharing. For a completely free data room option, you'll need to look elsewhere.
Membership cancellation affects document access If you cancel your SeedLegals membership, documents are stored for a period but not indefinitely. SeedLegals recommends downloading everything before cancelling. This means you can't treat SeedLegals as a permanent long-term document archive if you stop paying.
Not a standalone product This is the fundamental constraint. If you want only a data room, you're paying for the whole SeedLegals platform. If you're already using SeedLegals for legals, the data room is a valuable free addition. If you're not using SeedLegals for anything else, the cost-to-value ratio for the data room alone is poor.
SeedLegals works well when the data room is a bonus on top of a legal platform you're already paying for. When you only need a data room, or when SeedLegals' limitations are dealbreakers, these alternatives are worth knowing.
What it offers: Ellty is a dedicated pitch deck sharing and data room platform for startup founders. Unlike SeedLegals, it's not a legal platform with a data room bolted on - the data room is the product. That means you get cleaner analytics, faster setup, and pricing that doesn't bundle in services you don't need.
Key features:
Pricing:
No setup fees. No per-user fees. No round transaction costs. Start free and upgrade when you need more.
Best for:
Compared to SeedLegals:
When to choose Ellty:
What it offers: Docsend is a document sharing platform popular with founders for pitch deck tracking. It's strong on individual document analytics and has added basic data room functionality for due diligence.
Key features:
Pricing:
Per-user pricing means costs scale significantly with team size.
Best for:
When to choose over SeedLegals: When investor analytics depth matters more than integrated legals. When raising from US investors who expect Docsend links. When you don't need SEIS/EIS workflow.
What it offers: Not technically a VDR, but many early-stage founders use Google Drive with careful permission management as a free alternative to paid data rooms. It works for simple situations.
What you get:
Pricing: Free for basic storage. Google Workspace from ~£5.20/user/month for business features.
Best for:
When to choose over SeedLegals: When you need £0 cost and don't mind the lack of analytics, security features, or professional presentation. Not recommended for formal due diligence with institutional investors.
What it offers: Some founders use Notion to create an organized investor wiki or data room equivalent. It looks clean, is easy to organize, and can have page-level permissions.
What you get:
Pricing: Notion free plan exists. Team plans from ~£8/user/month.
Best for:
When to choose over SeedLegals: Only if you're at the earliest possible stage and aren't yet doing formal due diligence. Not appropriate for closing rounds.
If you're using SeedLegals for your round legals already: Stick with the built-in data room. It's included, it works for typical UK seed/Series A rounds, and keeping everything in one platform saves time. The limitations (no subfolders, limited analytics) are manageable for most rounds.
If you only need a data room: Don't pay for SeedLegals just to use the data room. Ellty starts free and covers the main use cases without the platform overhead. Docsend is worth considering if pitch analytics are a priority.
If you're a non-UK company: SeedLegals is UK-centric. Ellty, Docsend, or another standalone option will serve you better without the SEIS/EIS and Companies House framing that won't apply to your situation.
If you need enterprise-grade VDR for M&A: Neither SeedLegals nor Ellty is the right answer. Firmex, Datasite, or Venue are the appropriate tools for complex multi-party transactions.
The short answer: yes, if you're already using SeedLegals for your round. No, if you're only here for the data room.
Ask yourself:
About your use case:
About your team:
About your budget:
About timing:
SeedLegals data room is genuinely good for what it's designed for: UK startup founders running seed or Series A rounds who are already using the platform for legals. In that context, having your legal documents, cap table, and investor data room all in one place is a real time-saver. The platform is mature, the team support is strong (9am-6pm, unlimited chat/phone/email), and 60,000+ companies have validated the core workflow.
The problem isn't quality - it's fit. If you're a non-UK startup, only need a data room, have a complex document set requiring folder hierarchy, or care deeply about investor engagement analytics, SeedLegals' data room will disappoint you. The limitations are real and worth knowing before you commit to an annual plan assuming the data room will cover all your needs.
Treat SeedLegals data room as a bonus feature on a legal platform, not as a standalone VDR product. If you need a dedicated data room - especially a free or low-cost one without the legal platform bundled in - Ellty is worth a look first.
The data room is included at no additional charge for all paid SeedLegals members. There are no extra fees per user or per document. However, it requires a paid plan starting from £75/month or £590/year + VAT. The Deal Data Room specifically also requires an open funding round, which is purchased separately via Flex credits (or bundled in higher-tier plans).
There's no limit on the number of users you can add. Unlike per-user VDR pricing models, SeedLegals doesn't charge per investor or per viewer. Add as many investors, lawyers, and advisors as your round requires.
It's possible for straightforward, smaller acquisitions. For complex M&A with multiple bidders, large document sets, and sophisticated due diligence requirements, SeedLegals' data room is not built for that use case. The lack of subfolder hierarchy, limited analytics, and absence of advanced security features (watermarking, screenshot prevention) make it poorly suited for enterprise M&A. Use a dedicated VDR for those scenarios.
SeedLegals is primarily designed for UK companies using English law, SEIS/EIS, and Companies House. The platform has expanded to other markets (France, Ireland, US, Hong Kong, Singapore) with adapted services. For non-UK companies, the data room functionality itself is usable, but the platform's value proposition is much weaker without the SEIS/EIS and UK legal framework integrations.
SeedLegals stores your documents for a period after cancellation but doesn't guarantee permanent storage. They explicitly recommend downloading all documents before cancelling. Don't treat SeedLegals as a permanent long-term archive if you're not maintaining an active membership.
No, not currently. The data room uses groups (pre-set and custom) to organize access, but doesn't support hierarchical folder structures. Documents sit in a flat list within each group. This is frequently mentioned in user reviews as a limitation, and SeedLegals has acknowledged they're working to improve it.
The Pitch Data Room is linked to your public-facing investor pitch page. It's for sharing materials with prospective investors during early conversations. The Deal Data Room sits inside an active funding round and is designed for formal due diligence documents shared with committed investors. The Board Data Room is separate again, designed for governance materials with directors. You'll likely use all three at different stages.
You can track who has access and who has been added to which groups. SeedLegals' pitch page shows who has viewed your pitch. However, the Deal Data Room doesn't provide granular page-level analytics on individual document engagement the way dedicated analytics platforms like Docsend or Ellty do. If deep engagement tracking is important to your process, consider a standalone analytics-first tool.
Yes, investors need to be added to your round and create a SeedLegals account (free for investors) to access Deal Data Room documents. This adds a small friction point for investors unfamiliar with the platform. Most UK angel investors are already familiar with SeedLegals, but international investors may find it an unexpected extra step.
Yes, for standard startup fundraising. SeedLegals uses secure data transmission, encrypted storage, and access controls with explicit permission management. Documents are only accessible to users you've added. For typical seed and Series A rounds with commercial-grade due diligence requirements, the security is adequate. SeedLegals is also insured for claims related to their platform. For highly sensitive transactions requiring SOC 2 certification, advanced watermarking, or litigation-grade audit trails, a specialized VDR would be more appropriate.
Yes - the Pitch Data Room and Board Data Room are available on any paid plan without requiring an active round. These let you share materials with potential investors and board members. The Deal Data Room (with full group permissions for formal due diligence) requires an open funding round.
