Cardinal is the AI executive assistant for small business owners. It lives in your Slack, writes email in your voice, runs your calendar, and stays on top of your tasks — then waits for your yes on anything that matters.

You're the bottleneck. And you know it.

You're the last set of eyes on every email, the one who remembers the follow-up, the one juggling the calendar, booking the travel, and holding the loose ends nobody else is tracking. The business runs through you — which means it slows down the moment you do.

A full-time assistant would fix it. But hiring one, training one, and hoping they stick is its own second job — one most owners can't justify. So it all piles up in the one place it shouldn't: on you.

The shift

Most AI answers questions.
Cardinal does the work.

A chatbot waits for a prompt and hands you a paragraph. You still write the email, remember the follow-up, book the table, and prep for the call. Cardinal works the other way around — it lives in your Slack, watches your day across your inbox and calendar, does the work that needs doing, and brings it back ready for your approval.

"A chatbot answers.
Cardinal follows through."

A day with Cardinal.

Why a cardinal?

Because the name isn't decoration — it's the job. A cardinal is the one everything hinges on. And the bird itself works the way a great assistant does.

It's up before you are.

The cardinal sings first, before dawn. Cardinal has your day prepped and your inbox triaged before you sit down.

It learned your voice.

Every cardinal learns the local song and sings it in its own dialect. Cardinal works in your voice — across every channel — not a generic one.

It's always watching the field.

A cardinal spots what needs attention before it becomes a problem. Cardinal surfaces the loose ends and follows through.

It guards your time.

Cardinals defend their territory and keep intruders out. Cardinal routes the noise so you can protect the work only you can do.

It's the one that stays.

Cardinals don't migrate — they hold their ground through every season. No hiring, no turnover, no training a replacement.

It has your back.

Folklore says a cardinal means someone is watching over you. With Cardinal, someone always is.

One assistant, named by you, that works the way the bird does — quietly, loyally, and always a step ahead.

Premium, because it does a premium job.

Personal.

Trained on your voice, your people, and how you like things done — so it acts like your person, not a tool everyone shares.

Proactive.

It surfaces and drafts before you ask. This is the one thing owners want most, and the thing most assistants — human or AI — never quite deliver.

Trusted.

It drafts, but it doesn't send. Anything sensitive waits for your approval. You stay in control of every word and every dollar that goes out with your name on it.

Set up once.
Handed off for good.

01

Add Cardinal to Slack.

30 minutes, start to finish. Connect Gmail or Outlook and your calendar.

02

Give it your voice.

It learns from how you already write, so its drafts sound like you from day one.

03

Set your guardrails.

You decide what it handles on its own and what needs your yes.

04

Delegate in plain English.

Message it like you'd message a great assistant. It drafts, books, coordinates, reminds, and follows through — and only gets sharper.

You approve. Cardinal executes.

Cardinal moves fast without moving recklessly. It drafts, researches, schedules, and prepares in the background — but anything sensitive waits for you.

Drafts, not sends. Emails, bookings, purchases, and anything public wait for your approval.

Your data stays yours. Isolated to your account. Never used to train anyone else's assistant.

Full audit trail. See everything it did, everything it's waiting on, and why.

Security & control

Enterprise security. Small-business simplicity.

You're handing over your inbox and your calendar. We treat that like the trust it is.

Your tenant. Your data.

Every owner is fully isolated. Your emails, calendar, and voice model never touch anyone else's assistant.

Human approval gates.

Emails, bookings, and purchases wait for your yes. You can dial approval on or off per action type.

Revoke in one click.

Disconnect a tool, pause your assistant, or delete your data — from Slack, at any time.

The Cardinal principle

We're not building a super-agent.

There's a race to make AI that runs your entire business by itself. That's not us. Cardinal does three things exceptionally well — writes email in your voice, runs your calendar, and stays on top of your tasks — with a human in the loop for anything that touches money, calendar, or someone else. That's the whole product. That's the entire promise.

Built for owners, not org charts.

Cardinal is for solo consultants, agency owners, service-business owners, and lean teams — successful, short on time, who could use a right hand but can't justify a full-time hire.

It's not a $49 productivity toy, and it's not for people who want to babysit another app. If you've been burned by tools that overpromised, that's exactly who we built this for.

Half the price. For as long as you're here.

Cardinal will be $1,000/month. Founding beta members lock in 50% off — $500/month — for life.

A full-time executive assistant runs $60–100K a year, before you've trained them. Cardinal does the day-to-day of one, is on duty around the clock, and never leaves.
