Who it’s for

Four seats. One round.

A first round has four kinds of people in it, and Cairnul looks different from each seat. Pick the one that sounds like you. Thirty seconds, and you will know whether Cairnul is for you or not.

Cairnul is agentic fundraising compliance software for early rounds: SAFEs, advisor agreements, consents and authorizations, and the state and federal filings that come with them.

SEAT 01

You are running the round.

First time, US C-Corp, raising from people who already believe in you. Nobody handed you the checklist, so you are assembling one out of blog posts and a shared doc. That is not a you problem: the tools at this stage were built for the stage after yours.

This is you if

You run a US C-Corp and you are the one signing.

You are raising $25k to $25 million under Reg D Rule 506(b) or 506(c).

You are bringing on two to four Advisors on equity.

The next 12 to 18 months matter more to you than the next five years.

What you get

A Round with authorized terms

One open at a time, so the paper cannot contradict itself.

SAFEs sent, signed and recorded

YC post-money forms, countersigned, on your cap table the moment they close.

Every filing date on one calendar

Form D, state notice filings, the 83(b) window, each with the trigger that caused it.

Cairnul Agents doing the drafting

Drafted from verified library entries, declined and flagged when an entry is unverified or stale.

Your next step

Tell us about the round, or arrive on a referral link from a founder already inside and skip the review entirely.

Cairnul prepares every filing and files none. You approve and you send.

The honest part

Who Cairnul is not for.

Finding this out on the pricing page is expensive. Finding it out here takes ten seconds.

You are an LLC.

Cairnul supports US C-Corps. If you plan to convert, come back after.

You are raising outside Reg D.

Rule 506(b) and Rule 506(c) are the two exemptions Cairnul supports. Nothing else, yet.

Your round is bigger than this.

Above $25 million, or past a priced Series A, you have outgrown us.

You need someone to hold funds.

Cairnul is not a broker-dealer and never handles investor money.

You’re already a founder. Cairnul makes your first round look like it.
