GROWTH DEPT.

Security & trust

Your data, your machine, your rules.

Your AI team touches your ad budgets, your listings and your customers' data. Here is exactly what it can and can't do, where your data lives, and what happens if you ever leave. Written for a founder, not an engineer.

Eleven promises

What we promise every brand we run.

An AI that touches ad budgets and customer data has to earn it. These aren't policies in a drawer; they're how the machine is built.

  • Nothing changes without your approval

    Your AI team proposes in Slack with before and after. Nothing touches your ads, listings, prices or emails until you tap Approve, or until you've set limits it must stay inside. Approval always comes from someone on your team; your growth executive never approves for you. Your ad accounts stay yours: your AI team is a user on them, never the owner, and you can remove it from any platform in one click.

  • A record of every change

    Who proposed it, who approved it, what it was before and after, and when. The record can't be edited or deleted, and you get an hourly summary.

  • Your data lives on your machine, in your office

    Every number from every store, marketplace and ad account is kept on the machine we built for you. Not in our cloud. Not on our laptops. For the first thirty days the machine sits with us while we connect everything; it is still your machine and your accounts, and it ships on Day 30.

  • Nobody trains on your data

    When your AI team or Claude works on a question, only the figures that question needs go to the AI provider, under an account in your company's name, on business terms that rule out training and keeping. Customer names never cross. Nothing goes to Growth Dept.

  • Claude can read, never change

    When your team asks Claude about the business, it can only look. Changes still go through your AI team and your approval.

  • You decide who can ask what

    Finance can see margins; a new hire can't. Anyone not on your list gets no answer at all — not a partial one.

  • Backups you can restore

    Your data is backed up every night and we test a restore every week, so a backup is something that works, not something that exists.

  • Private access only

    Your machine isn't reachable from the public internet. Your team gets in through a private connection; nobody else gets a door to knock on.

  • Our key is your switch

    After Day 30 we hold no standing key. When your AI team needs a hand from us, you grant access from Slack for that job, every sign-in by us lands in the change record with a name and a reason, and it switches off when the job is done. One message turns it off early, and it stays off.

  • Everything is yours if you leave

    The machine, your AI team, your data, your playbooks and your Slack app stay with you and keep running. We hand over the manual.

  • Where a question goes

    The honest version: the numbers a question needs do leave the machine for the AI, under your own account. Customer names never do.

    1. 01

      Your machine

      Every number, every customer record. Stays here.

    2. 02

      The AI provider, under your account

      Sees only the figures the question needs. Business terms: no training, nothing kept.

    3. 03

      The answer, in Slack

      Back to the person who asked. Nothing goes to Growth Dept.

    Customer names, emails and addresses never cross. The machine strips them out itself, and we test that every six hours.

  • If the machine fails, your ads keep running

    A replacement ships with your last backup on it, and your growth executive is on the phone until it arrives.

    1. 01

      Backed up nightly

      Every number, every playbook, every change record.

    2. 02

      Replacement ships

      With your last backup already on it.

    3. 03

      Ads keep running

      At their last approved budgets. Nothing changes without you.

The first thirty days

Before it reaches your office, it is still yours.

For one month the machine sits with us while everything is connected. Here is what protects it during exactly that window.

  1. 01

    Where it sits

    On our desk, in our office, for thirty days. It is your machine and your accounts the whole time.

  2. 02

    Its disk is encrypted

    Powered off, it is a brick to anyone without the key. It is already behind the same private connection your team will use.

  3. 03

    Every connection is yours

    Made under your own store, marketplace and ad accounts, so you can cut any of them from the platform side at any moment.

  4. 04

    The record runs from day one

    The same change record, from the first sign-in. The Day 30 hand-off includes who touched it and when.

How a change happens

Propose. Approve. Go live. On the record.

Every change to your ads, listings, prices or emails takes the same four steps. There is no shortcut, for your AI team or for us.

  1. 1 / 4

    Your AI team proposes

    In Slack, with before and after.

  2. 2 / 4

    You approve

    One tap. Or skip it.

  3. 3 / 4

    It goes live

    Inside the limits you set.

  4. 4 / 4

    It's on the record

    Who, what, when — kept forever.

The details

For your technical person.

Eight things they'll want to know, in plain words. Ask to see any of them on the install call.

  • Approval gates on every money-moving action

    Ad budgets, bids, prices, listing edits and customer emails are previewed with old and new values, approved by a named person, and refused if the target changed in between.

  • An append-only change log

    Every approved change writes a record that can't be edited or deleted, and an hourly summary of every change on every ad platform — ours, yours or an agency's — posts to Slack.

  • Customer names never reach the AI

    Your AI team and Claude only ever see numbers with names, emails and addresses stripped out. The machine enforces that rule itself, not a policy document, and we test it every six hours.

  • Nightly backups with weekly restore tests

    Everything on the machine is backed up every night, encrypted. Once a week a backup is restored and checked, and the recovery steps are written down.

  • No door from the public internet

    Your machine cannot be reached from the open internet. Your team gets in through a private connection with two-step sign-in, and the short list of who can get in is checked and re-applied every time the machine starts.

  • Your own AI accounts and billing

    Your AI team and Claude run under AI accounts opened in your company's name, on business terms that rule out training. Software subscriptions and AI usage are additional costs, billed directly to you by the providers. The AI sees the answer to each question, never your whole set of records.

  • No cloud to certify

    There is no Growth Dept cloud holding your data, so there is nothing of ours to audit. Your records stay on a machine in your office; the only thing that leaves it is the figures a question needs, sent to the AI under your own account with names stripped out. We will sit with your security lead and show every control on this page.

  • Our access is granted per job and on the record

    After Day 30 we hold no standing key. When a job needs us, someone on your team grants access from Slack for that job; every sign-in by us is written to the same change record with a name and a reason, and access ends when the job does. One message ends it early.

Next step

Forty-five minutes with our team. Your AI team in your Slack a week later.

Bring your store URL and the numbers you already trust. You'll leave with a written plan: what your AI team takes on first, what it costs, and when it's in your Slack.
