Any file name, any layout. Read on your computer, matched to your cap table.

Capfolder does what Carta, Pulley, Cake Equity, Ledgy, Eqvista and every other cap table and stakeholder platform do. The difference: it's free, your data stays on your own devices, and you can plug in your own AI to make the annoying tasks disappear.

Built on open source

Why we built this

We lost our cap table paperwork.

We raised our seed on SAFEs from 28 investors. Some signed in Pulley. Some sent their own paperwork. Some signed by email.

When we needed the documents, the data was gone. We're now digging through old inboxes and asking investors to sign again.

A cap table is the most important record a company has. It shouldn't depend on a vendor, a subscription or a login. So we built one that lives in a folder you own, and open-sourced it so it can't disappear.

What it does

Everything Pulley did that you actually used.

The cap table is the first screen

Who owns what, with everyone's vesting, on one page.

What's missing, flagged

Found before an investor's lawyer finds it.

SAFEs, grants and shares in two minutes

Record them from a short form, then send your signed-off PDF for signature. Capfolder adds the signature page.

Excel or CSV, any date

For the auditor, the bank or the tax office.

Math you can check

Click a holding to see how its numbers were computed. Tests are public.

A real desktop app

Fast, small, and no login screen.

Compare

Rent your cap table, or own it.

Hosted tools do more today. Capfolder is the one that can't disappear with your data.

Features vary by vendor and plan. Free tiers: Cake Equity ≤5, Eqvista ≤20, Carta Launch ≤25 stakeholders (and under $1M raised), Ledgy ≤25; Mantle has a free plan. Paid entry points: Cake $1,000/yr, Mantle $1,200/yr, Ledgy from €5,000/yr; Carta doesn't publish prices, so its figures are from Vendr purchase data (Feb 2026). AngelList stopped taking new cap-table customers in 2026. Checked October 2026; check each vendor before deciding. Spotted something wrong? Open an issue.

Signatures

The only thing in the cloud is the unsigned document.

It waits on the relay until everyone has signed. Then it comes back to your folder, is checked against your original, and the relay deletes its copy (within 7 days).

Your folderoriginal + hash

Relay emptyholding 1copy deleted

Investorsigns in browser

No account for signers. A link in their email, that's it.

Matched to your original. Every page you sent must come back with the same text and nothing added on top.

Self-host the relay. Documenso plus a small API, both in the repo, if you want zero cloud.

Bring your own AI

Plug in your local AI. Give your folder superpowers.

Ollama or LM Studio keep everything on your machine. The AI reads the odd PDFs the rules can't, and fills in a proposal. Every field is checked against the cap table, and nothing is saved until you click.

Sort my old Pulley folder (14 files)

11 filed. 3 need you. scan_0042.pdf looks like Fund X's SAFE ($250k, Mar 14, 2023), signed as “Fund X Ventures I, L.P.” Same investor?

Yes. Remember that name.

Questions

Who can see my data?

Your cap table and documents stay on your computer. A document you send for signature sits on the relay until it's signed, and whoever runs the relay could read it (self-host it if that matters). The app sends an anonymous install count; turn it off in Settings. Details below.

Can I move from Pulley or Carta?

Import their export (spreadsheet or OCF). Totals are checked against it before anything is saved. Then drop in your signed documents and they're sorted for you.

What does it cost?

The app is free. Pay what you want if it helps you. A paid hosted relay for teams may come later.

Which companies does it support?

Delaware C-corps first. More jurisdictions after.

Is this legal advice?

No. Capfolder records what you and your lawyer decided; it doesn't write your documents. Have a lawyer review them.

Own your cap table.

Privacy

This page. Fonts and images come from this site. Visits are counted with Plausible: no cookies, no personal data, your IP isn't stored. The star count and download links are read from GitHub's public API when the page loads, so GitHub sees that request.

The download form. When you click "Get the download", the form is loaded from Tally. It asks for your email and your computer, only to send you new versions. Ask through a GitHub issue to be removed, or reply to any email.

The app. Your cap table and documents stay in your folder. Documents you send for signature pass through the signing relay until everyone has signed, then the relay deletes them (within 7 days, or 30 if never signed). The app sends an anonymous install ping (a random install id, the app version, your operating system, and yes/no for "imported", "has documents", "sent for signature") once on first run and then weekly, only after you accept the terms. The relay keeps the day, not the time or your IP address. Turn it off in Settings → Privacy. The code that sends and stores it is public in the repo.
