Self-hosted on the Cloudflare edge

Stop sending docs
into the dark.
Know who's really reading.

You poured weeks into that deck. The moment you hit send, it disappears into someone's inbox — and you're left guessing. Folio gives you the truth: who opened it, where, on what, and how long they lingered on the slide that matters. Private. Signed. Yours.

Investor deck access tracking for their Pre-Series A raise — token-gated pitch deck with 47-point analytics on every open.
India's cycling OS Pre-Series A ₹500M thesis

You sent the proposal three days ago.
Did they even open it? Did they forward it? Are they still interested — or already gone?

That silence is the worst part of every deal. Folio ends the guessing. The instant someone opens your document, you know — and you walk into the next call already holding the cards.

Built for the moments that matter

When the document is the deal

Some files are just files. Others carry your raise, your number, your reputation. Folio is for the second kind — the ones you can't afford to lose track of.

Founders raising capital

Your pitch deck is your future. See which partner opened it, how long they spent on the financials, and whether it got forwarded around the firm — so your follow-up lands at exactly the right moment.

Index opened it twice last night and spent six minutes on the traction slide. Time to call.

Sales teams closing

Stop chasing ghosts. The moment a prospect reopens your quote, your rep gets the signal — and reaches out while you're still top of mind, not a week too late.

He reopened the pricing page on his phone at 9pm. That's a buying signal you can act on.

Legal & M&A

Term sheets and diligence files demand a paper trail. Every open is signed, logged, and tied to a verified link — so you know precisely who saw what, and when, if it ever matters.

Forensic-grade access logs on every confidential document, without a heavyweight data room.

Consultants & agencies

Your proposal is your craft on the page. Watch the client read it slide by slide — and tailor the kickoff call to the exact sections that made them lean in.

They read the scope twice and skipped the price. Now I know where to start the conversation.

Real estate & deals

Off-market memos and investor packets, shared with confidence. Send one signed link per party, cap the opens, and revoke the instant a deal goes cold.

One link per buyer, full visibility, killed in one click when the listing moves.

Recruiting & talent

Sending an offer, a JD, or a candidate packet? See the moment it's opened — and read the interest in the timing, not just the reply.

She opened the offer at midnight and again at breakfast. That's a yes forming.
Everything in one console

A complete document command center

Upload, tokenize, share, and watch — every capability you'd expect from an enterprise data room, on infrastructure you control.

Core

Memorable access tokens

Generate human-friendly links like apex-node-4821 instead of opaque hashes. Set max-uses, expiry dates, and attach any document — each link is independently revocable in one click.

one-time usedate expiryinstant revokeper-recipient

Branded reading room

Recipients open a clean, your-logo viewer — no login, no friction, no download leakage.

Real-time activity

See opens the instant they happen — recipient, location, device, and dwell signals.

Email delivery

Send signed links straight to recipients with branded transactional email built in.

Role-based team access

Three tiers — Super Admin, Admin, and Viewer — so your whole team can manage documents and read analytics without sharing one password.

Multi-tenant workspaces

Every document, token, and log is scoped to a workspace. Run separate brands or clients from a single deployment with zero data bleed.

Forensic-grade analytics

Know exactly who opened what

DocSend tells you "someone viewed it." Folio captures 47+ signals on every open — geography, network, device, and client environment.

A Tuesday night, in real life

The follow-up that wrote itself

It's 9:47pm. You're about to close the laptop when Folio lights up. The partner you've been chasing for two weeks just opened your deck — and they're still reading.

You watch it happen. Eight minutes on the financials. Back to the team slide. A second device joins from the same firm. This isn't a polite skim — this is a room making a decision.

The next morning you don't send a nervous "just checking in." You send the one email that matters, to the people who actually read it, about the exact thing they cared about. That's the difference between hoping and knowing.

Why people never go back

It's not about tracking. It's about peace of mind.

The data is the feature. The calm is the reason. Here's what changes the day you start sharing through Folio.

No more wondering

Trade the pit-in-your-stomach silence for a live feed of exactly what's happening to your document.

Perfect timing

Reach out the minute interest spikes — not days later when the moment's already passed.

Total control

Cap opens, set expiry, revoke in a click. Your confidential work stays exactly as private as you decide.

Quiet confidence

Walk into every call already knowing what they read. Preparation beats anxiety, every time.

Built for confidential material

Security that protects the sender

Cryptographically signed links, owner-IP bypass, and hardened auth — so your documents can't be forged, replayed, or guessed.

HMAC-signed links

Every share URL carries an ?sig= HMAC-SHA256 signature. Tampered or hand-crafted links are rejected at the edge with a timing-safe comparison — guessing a token is useless without the workspace key.

Trusted-IP bypass

Whitelist the creator's IP plus up to five reviewers. Their opens never hit the access log and never burn a max-use — preview your own decks without polluting recipient analytics.

Hardened authentication

Admin passwords use PBKDF2 derivation; sessions are HttpOnly, Secure, SameSite-Strict cookies scoped to /admin. The signing key never leaves the server or appears in any API response.

From upload to insight

Live in three steps

No infrastructure to provision, no SDK to wire up. Sign in and start sharing in minutes.

1

Upload your document

Drop in an HTML deck or document. It's stored encrypted in your own D1 database — never on a third party's servers.

2

Generate a signed link

Create a memorable, HMAC-signed token per recipient. Set usage limits and expiry, then copy or email it directly.

3

Watch every open

The moment a recipient opens it, 47+ data points land in your dashboard — who, where, on what, and how often.

Pricing

Start free. Upgrade when it's working.

No card to start. Every plan includes signed links, the branded reading room, and forensic analytics — paid tiers just lift the limits.

From the people who send what matters

The relief is the product

"I used to refresh my inbox like a maniac after sending a deck. Now I just watch Folio. The night a fund opened it four times, I knew we had a term sheet coming before they did."

RA
Rohan A.
Founder, seed-stage SaaS

"My reps stopped guessing. The second a buyer reopens the proposal, we know — and we call. Our follow-up timing went from random to surgical, and close rates followed."

MK
Maya K.
Head of Sales, B2B agency

"We share term sheets that absolutely cannot leak. Signed links, capped opens, instant revoke, a full audit trail on our own infrastructure. It finally feels like the document is ours again."
