The read receipt, in detail
What you see when an investor opens your deck
Most tools give you one number: opens. HummingDeck shows you the whole behavior, slide by slide, viewer by viewer.
01
Per-slide engagement
Beyond a binary "opened" flag, you see which slides they read and how long on each. Four minutes on the team page reads differently than 30 seconds across the whole deck.
02
Unique viewers
Send a personal link to one investor. If multiple unique viewers appear on it, you know it was shared internally. The number of viewers, not just the click, is the signal.
03
Return visits
An investor viewed your deck on Monday, then came back Thursday without you following up. Something changed on their end. Return visits and forwarded reads are usually the two clearest signs the conversation is alive.
04
Bot filtering
VC firms use enterprise email with SafeLinks and Proofpoint. Not every "view" is real. HummingDeck's three-layer detection filters automated scans so every view represents a real investor.
05
Real-time alerts
Get a Slack message or email the moment an investor opens your deck. No dashboard to keep open.

How it works
From upload to engagement in three steps
1
Upload your pitch deck
PDF, PowerPoint, or Google Slides. Drag and drop. Your deck is ready to share in seconds. Attach your financial model (Excel) and other diligence docs alongside it.
2
Create a unique link for each investor
One link per investor. Send it open, require email to view, or restrict to a verified allowlist for confirmed identity. Each link tracks individually.
3
Share and track
Send via email, LinkedIn DM, or warm intro. See what happens in real time. Update your deck anytime, and every existing link automatically serves the latest version.

The forwarding signal
The signal most tools can't show you
Send a personal link to one investor. When extra unique viewers appear on it, with different locations and time on each slide, the deck has been forwarded.
30% of decks that result in meetings are shared internally before the meeting is scheduled.
Multiple viewers on one link usually means a partner is reviewing internally.
Investor data room
One link for your entire fundraise
Bundle the deck, financial model, cap table, team bios, and a Calendly booking into one tracked link. Per-investor analytics across the whole packet, not just the deck.
One branded page, one link
Embedded Loom, Calendly, Typeform, Figma, Notion
See time spent on each document, per investor
Replace any document mid-raise without changing the link
You're sending your deck to 50+ investors for the first time. Know who opened it, which slides held their attention, and whether the link was shared with others. Time your follow-ups based on real engagement, not guesswork.
Growth-stage founders
Larger rounds mean more firms evaluating simultaneously. Track engagement across dozens of investor conversations. See which firms are actively reviewing vs. going cold.
M&A advisors and bankers
Share CIMs, teasers, and deal memos with per-page tracking and controlled access. Know which buyers are seriously evaluating before the first call.
Accelerators and scouts
Share portfolio company decks with LPs or co-investors. Track which companies generate the most interest and who's coming back for a second look.
Early-stage founders
You're sending your deck to 50+ investors for the first time. Know who opened it, which slides held their attention, and whether the link was shared with others. Time your follow-ups based on real engagement, not guesswork.
Access control
Pick the access model that matches the stage.
Cold outreach works best with no friction: personal link, no email gate, no login. Confidential late-stage materials, financials, term sheets, the full data room, belong behind an allowlist of verified emails. Choose per share.
Restriction · Low
Anyone with the link
No email, no login. Best for cold outreach where every extra click costs you a view. You still get per-slide analytics and unique-viewer detection.
Plus applicable VAT/tax. Tax is added at checkout. Pricing for businesses. Prices exclude VAT/sales tax, which is calculated at checkout based on your location.
Why founders use HummingDeck as their fundraising data room
By Series A, investors expect more than a deck. A fundraising data room puts your pitch deck, financial model, team page, and customer references behind one branded link, with per-document analytics across the whole package.
Most virtual data rooms hide that behind enterprise pricing and a sales call. HummingDeck includes it from the Starter plan.
Same per-page tracking, unique-viewer detection, bot filtering. Live in 5 minutes.
FAQ
Frequently asked questions
Do investors need to log in to view my deck?
No. They click the link and view your deck in their browser. No account, no download, no friction.
Should I require email gating?
Generally no. Investors consistently cite email gating as the #1 annoyance with deck-sharing tools. Use unique per-investor links instead. You get individual tracking without asking for anything.
Can I update my deck without resending the link?
Yes. Replace the file and every existing link automatically serves the new version. Investors always see the latest deck.
Can I revoke access after my round closes?
Yes. Set link expiration dates or manually disable links at any time.
How do I know if an investor forwarded my deck?
When you send a personal link to one investor and multiple unique viewers appear on that link, you know it was shared. HummingDeck identifies each viewer separately by fingerprint and location.
Is this really free?
Yes. The free plan includes pitch deck tracking with per-slide analytics, unique-viewer detection, and bot filtering. Up to 5 documents and 1 data room. No credit card required.
How is this different from DocSend?
HummingDeck includes unique-viewer detection, return visit alerts, bot filtering, and data rooms with 25+ embed providers on every plan. No monthly view caps. See our full comparison for details.
Can I use this for M&A or due diligence documents?
Yes. Share CIMs, deal memos, and teasers with per-page tracking and controlled access. For full due diligence data rooms with many documents, consider the Pro or Business plan.
What's the difference between a data room and a deal room?
A data room (also called a virtual data room or VDR) is the standard term for a secure document space used in fundraising and M&A. "Deal room" is sometimes used as a synonym, especially in sales contexts. HummingDeck supports both use cases. For fundraising, founders typically call it a data room.
How fast can I set up a fundraising data room?
Under 5 minutes. Upload your deck, drag in your financials and team docs, generate one link. Share with investors. No configuration, no annual contract.
Can I share my financial model as an Excel file?
Yes. Upload your .xlsx (or legacy .xls) straight into the room and investors view it tab-by-tab in the browser: ARR build, P&L, cohorts, scenarios. Charts and cell formatting render. You see which partner spent time on which tab. No need to flatten to PDF first.
What file types can I upload?
PDF, PowerPoint, Word, Excel, Google Slides and Docs, and HTML. Decks, financial models, one-pagers, and diligence docs all track the same way.
Can I use my own domain?
Yes, on the Business plan. Serve every link and data room from your own custom domain for a fully branded investor experience.
