CapSign
The registry of private companies

Your cap table, verified and free.

Claim your company, move your cap table off spreadsheets and legacy vendors, and run equity, governance, and your next raise from one register of record.

Moving from another provider or a spreadsheet? We'll help you bring it over. Export in Open Cap Format any time.

How it works

From spreadsheet to verified register

CapSign becomes your system of record in four steps, and we help with the move.

  1. 01

    Claim your company

    Sign in with a work email on your company's domain. We confirm you're an officer before the page is yours.

  2. 02

    Move your cap table

    Upload Open Cap Format files, or send us your current provider's export and we'll convert it. Review every holder before you move it over.

  3. 03

    Choose your register

    Keep it on CapSign, publish public onchain lots, or run a confidential onchain register only you can read.

  4. 04

    Raise from your investors

    Open a Rule 506(b) or 506(c) placement. Investors verify, sign, and pay. Closing issues their shares.

One register, every workflow

Everything that touches ownership, in one place

The cap table isn't a report you update after the fact. Grants, consents, raises, and transfers all write to the same register.

Raise

Run your own private placement

Data room with NDA, identity and accreditation checks, subscription agreements, and payment tracking. Closing issues shares straight onto your register.

How placements work

Sign

Native e-sign that updates the cap table

Grant notices, consents, and subscription agreements go out by email. When the last signature lands, the record updates itself.

Signing and documents

Equity plans and 409A

Options, RSUs, vesting, acceleration, 83(b) tracking, and the ISO $100k limit.

Transfers and corporate actions

Right of first refusal, legends, splits, repurchases, dividends, tender offers, and mergers.

Modeling

Model the next round and the exit waterfall against the cap table you already have.

Governance

Board consents, signed natively and tied to the grants and issuances they approve.

Filings and tax

Franchise tax, annual reports, foreign registrations, Form 3921, Rule 701, and ASC 718.

Subscription payments

Every investor gets a wire reference, so you match incoming funds and mark them paid.

The index

A public page for every private company

Search the companies on CapSign. Unverified pages show public facts only. Verified means the company claimed its page and keeps its live register here.

  • Verified on CapSign is earned, not bought: a confirmed officer and a live cap table.
  • Show capitalization totals only if you opt in. Holder names are never public.
  • Rule 506(c) offerings can appear on your page. Rule 506(b) offerings never do.

Your register, your rules

Choose how public your ownership is

Choose a register when you move your cap table over. Every issuance after that, from grants to placement closes, lands in the same place.

Keep it on CapSign

Your cap table of record lives in CapSign with a signed hash receipt.

Onchain registers run on Base Sepolia today and move to Base mainnet with our first verified issuers. No wallet needed: CapSign submits and pays for the transactions.

For investors and employees

Every company you own, one login

Holders see their shares, options, and SAFEs across companies, with the documents behind them. No more digging through email for a grant notice.

  • Verify your identity and accreditation once, then reuse it.
  • Sign subscription agreements and grant notices in a few clicks.
  • Wire funds with a reference that matches your subscription.
  • Track vesting and 83(b) deadlines in one place.

Pricing

Free. Not a trial.

The cap table, claiming, OCF import and export, e-sign, and issuer placements cost nothing. A verified register is worth more to everyone than a seat license.

What's included

Trust

Software, not a broker.

Companies run their own offerings. CapSign never finds investors, recommends securities, or matches buyers and sellers. Every placement surface says so.

Security and compliance

Questions

What does it cost?
Claiming your company, the cap table, OCF import and export, e-sign, and issuer-conducted placements are free.
What does Verified mean?
The company claimed its page and keeps its cap table of record on CapSign. It says nothing about valuation, financials, or investment quality.
Is CapSign a broker-dealer?
No. CapSign is software. The company conducts its own offering. We don't find investors, recommend securities, or match buyers and sellers.
Who can see my cap table?
Your team and each holder's own position. Public pages show totals only if you opt in. Holder names are never public.
Can I leave?
Yes. Export your cap table as Open Cap Format at any time. Your register is yours.
Do I need a crypto wallet?
No. You sign in with a passkey or email. Onchain registers are optional, and CapSign handles the transactions for you.

CapSign provides software. Companies conduct their own offerings. CapSign is not a broker-dealer and does not find investors, recommend securities, or match buyers and sellers.
