Captain
Usage-based cap table software

The cap table for all.

Most cap table software charges by stakeholder, by seat, or by a subscription you pay whether you use it or not. Captain charges $10 when a document is executed. Nothing else. Reads are free, drafting is free, and the 83(b) deadline tracker — the feature that saves someone's stock — is free forever.

Why it costs this little

You pay for outcomes, not for existing.

A cap table is mostly reading. Charging for the reading is how the incumbents reach four figures a year for a company with nine stakeholders and one option pool.

Free forever

Cap table reads and snapshots, the stakeholder portal, adding classes and stakeholders, drafting, option and warrant exercise, and 83(b) deadline tracking. A holder's right to their own shares never depends on a balance.

Metered

Four events, all of them a completed, value-bearing outcome: an instrument executed, an e-signature envelope completed, a board consent executed, a compliance packet exported. Nothing bills on an attempt.

Prepaid credits

1 credit = $1.00. Buy a package, spend it as you go. Unused paid credits are refundable 1:1 for 180 days — no per-lot rate, no tier history, no forfeiture of money you did not spend.

No lock-in

Export the whole ledger, every document and the audit chain at any time. Closing your account returns the unused balance rather than keeping it.

Packages

Buy credits. Spend them when something happens.

One closed-loop grant — document generated, signed, and on the ledger — is $12: $10 for the instrument and $2 for the envelope. A seed-stage company issuing twenty grants a year spends $240.

Starter$25 25 credits$1.00 / credit
Small$45 50 credits$0.90 / credit · +5 bonus
Standard$85 100 credits$0.85 / credit · +15 bonus
Best value$160 200 credits$0.80 / credit · +40 bonus

Bonus credits are a volume discount and are not refundable; paid credits always refund 1:1. Draws spend paid credits first, oldest first — so the credits closest to aging out of refundability are always the ones spent.

Live — running against a real ledger

Model the round before you sign it.

Drag anything. The pool comes out of the pre-money, a post-money SAFE cap does not protect against the round that follows it, and the exit waterfall conserves to the cent. Every figure below is computed server-side — this page holds no arithmetic.
