Now onboarding founders

Your chief of staff.
In iMessage.

Chief runs your day over iMessage. Schedules, follow-ups, research, inbox triage, vendor chasing. Everything it learns gets written to a private Obsidian vault in your iCloud, so the brain you build is yours forever.

The problem

You are the bottleneck.

Every follow-up sits in your head.

Every decision routes through you.

Every loose end becomes tomorrow's fire.

A chief of staff fixes this. You can't afford one yet.

How Chief works

Three things. That's the whole product.

01 Text

Send Chief anything.

Tasks. Reminders. Half-formed thoughts. Voice notes. Screenshots. No app to open. No new tool to learn. If you can text it, Chief can act on it.

02 Execute

Chief does the work.

Schedules meetings, drafts emails, researches prospects, chases vendors, summarizes calls, and runs your follow-ups. It works inside the tools you already pay for.

Behind every text

Chief isn't one assistant.
It's a team that built itself for you.

On day one, Chief reads your Gmail, calendar, Notion, and meeting transcripts. Within an hour, you have a custom team of sub-agents and a starter playbook of slash commands tuned to how you actually work. Every week, the playbook gets sharper.

01 The team

A team behind
every reply.

Behind the iMessage thread is an org chart of specialists. Sales drafts the email. Operations updates Notion. Finance logs the expense. Research pulls the brief. Each sub-agent has its own tools and memory — and reports back to Chief.

You stay on iMessage. Chief delegates and consolidates. Every artifact lands in your vault.

02 The playbook

Anything you do twice
becomes a one-line command.

Day one, Chief audits your inbox, calendar, Notion, and meeting transcripts to find the work you do over and over. Then it builds you a starter playbook of slash commands tuned to how you operate.

  • → Run by text. Send /weekly-investor-update — Chief executes.
  • → Run on schedule. /inbox-zero every weekday at 7am.
  • → Library compounds. Two new skills proposed each week. Approve, edit, or skip.
The vault

The first AI assistant whose memory you actually own.

Most AI assistants are black boxes. Their memory lives on someone else's servers and disappears the day you cancel. Chief is the opposite. Every contact, decision, follow-up, and workflow it learns gets written as plain markdown to an Obsidian vault in your iCloud. Open it. Read it. Edit it. Take it with you.

Who it's for

Built for founders who can't afford a team yet.

You're running sales, ops, recruiting, and product at the same time. You don't have a chief of staff. You don't have an EA. You have iMessage, a calendar, and a Notion that's three weeks out of date. Chief is the leverage you need before you can hire.

Archetype 01

Solo founder, pre-seed to Series A.

Archetype 02

Two-person team running on duct tape.

Archetype 03

Operator who left a real job and now does everything themselves.

FAQ

Questions, answered short.

Why iMessage?

Because you're already there. No new app. No new login. No friction.

What if I prefer WhatsApp or Telegram?

Both supported. iMessage is just the default for Mac and iPhone users.

Where does my data live?

In an Obsidian vault inside your personal iCloud. We don't store your knowledge base on our servers. You own it.

What if I cancel?

You keep the entire vault. Everything Chief learned about your business is yours. Forever.

How is this different from ChatGPT?

ChatGPT is a chatbot. Chief is an operator. It runs work, takes actions, and remembers everything in a knowledge base you control.

Stop being the bottleneck.

We're onboarding 25 founders this month.
