AI Harness Labs
For US businesses

Run the business. Not the busywork.

A trained intern builds AI agents for the jobs that eat your week, in 1 to 3 months and at no cost to you. An expert AI checks every step, and you keep the software.

Your agent learns how your business works, in a memory you can see, correct and delete. In time, your team can work in apps you own instead of renting.

Start from 664 workflow designs written for 53 kinds of business, from plumbers and dental practices to online stores.

See what this is worth to a 10-person business, with every source.

  • You keep the code

An illustration: your agent works in your own apps (team chat, tasks, customers, leads, docs and the assistant), recalls what it knows about your business from a memory where each fact shows where it came from and can be corrected or withdrawn, and a change it wants to make waits for your approval.

Inside a small business

Open up the business, one department at a time.

Front office, sales, marketing, money, operations and people. Each has jobs an agent can run from your own information, waiting for your approval where it matters. Scroll, and the shop opens one department at a time. Then see how it is built and what stays with you.

Once it is built, it hands each job to its department's agent, watches all of them, checks the day's numbers against what is normal for you, and sends one morning summary of what happened, what it did and what needs you.

How it gets built, and what stays with you

Act II · before anything is built

Six advisors read your business before anything is built.

While you answer the interview, a board of AI advisors reads along and leaves short notes: a question worth asking, an opportunity, or a risk.

How the board of advisors works

Act III · the build

Your intern starts from a ready design.

Start from 664 workflow designs written for 53 kinds of business, from plumbers and dental practices to online stores.

Browse the workflow designs

Act IV · business memory

A brain for your business.

Turn on business memory and your intern's agent learns how your business works: facts from your interview, the brief and the check-ins, with personal details replaced. You see, correct and delete what it knows, and export it at handover.

How business memory works

Act V · the agents at work

Nothing sent without you.

Messages the agent would send wait for your approval, unless you let one kind run on its own, and a batch is one decision. QuickBooks Online, Square, HubSpot and Jobber are available once you connect them.

Approvals and standing permissions

Act VI · yours to keep

Own your team's apps instead of renting them.

In time, replace the tools only your team uses with your own: open-source team chat, tasks, customers, docs and an assistant, on a server you rent. Connect to accounting and payments, never replace them.

Yours to keep

When the intern leaves, everything stays.

Three things are yours for good: a memory of how your business works, a board of advisors that read it with you, and apps your team owns instead of rents.

Business memory

A brain for your business.

Your business gets a memory of its own, kept apart from every other business. It holds the facts your intern's agent needs, each with where it came from, so nobody asks you the same thing twice. It is off until you turn it on.

  • What goes in: your interview, the brief, the weekly check-ins, and a one-line note when the agent reads one of your systems. Never customer lists, card numbers or raw emails.
  • Names, email addresses, phone numbers and street addresses are replaced with placeholders before anything is saved. Search is by keyword only, on a server we run in Germany.
  • You see what your agent knows. Correct a fact, withdraw it, or turn memory off and delete it.
  • Your intern's agent connects with a token of its own. It can recall facts and add notes; it cannot delete anything, and you can revoke it at any time.
  • At handover, "Export my memory" downloads every fact, ready to import into your own apps.
What your agent knows
Example. Personal details become placeholders such as [person].
How business memory works
Board of advisors

Six advisors read your business before anything is built.

While you answer the interview, a board of AI advisors reads along and leaves short notes: a question worth asking, an opportunity, or a risk. You get the view of finance, marketing, operations, sales, technology and risk on your own business, side by side, before your intern writes a line of code.

  • Roles, not people: one seat for each part of a business, never a real person's name, photo or likeness.
  • Every note shows what it rests on, in your own words. A note that uses a figure you did not give is thrown away before you see it.
  • Ask any advisor, or the whole board, a question during the interview, and any time from your dashboard. Press "Turn this into steps" to put a note on your Tasks list, marked for you or for your intern.
  • Suggestions, not legal, tax or financial advice. When something needs a professional, the Risk advisor says which kind to ask.

Example. Notes rest only on what you told us.
How the board of advisors works

At handover, your memory export goes into the suite's assistant. Approve it once.

Your own apps

Own your team's apps instead of renting them.

The Business Suite is open source under the MIT licence: team chat, tasks and projects, customers, leads from your website, docs and procedures, and an assistant with the business brain, on a server you rent in your business's name. Your intern sets it up and changes it to fit how you work.

  • Replace the tools only your team uses. Connect to accounting, payments, payroll and banking, never replace them. Leave regulated records where they are.
  • The subscription review in your interview lists what you pay for each month and shows what you could save, from your own figures.
  • Anything the assistant or an import wants to change waits for a person's approval. A batch is one approval, and nothing is written twice.

  • Turn this into steps

    Any advisor note or proposed project becomes one to four concrete steps on your Tasks list, each marked for you or for your intern.

In writing

A 15-minute interview. Everything else in writing.

  • The interview and the brief

    A 15-minute interview. Then a brief.

    An AI interview asks about your business and proposes up to three AI projects that fit it. Approve the ones you want, and each becomes a scoped brief, sized for 1 to 3 months.

    How it works, step by step
  • The completion fee and the review

    $50 for each completed internship

    Complete an internship with an honest written review of the intern's work, and we pay you $50. It pays for your time; we make no promise of income.

    Read the Business Agreement
  • The agreements and the NDA

    Everything in writing, before anyone starts.

    You confirm the Business Agreement when you post, and each intern signs an NDA with you before they see anything beyond the brief. You own what is delivered.

For the people who build these

Want to be the one who builds it?

Our interns learn by building one for a real US business, with an AI mentor at their side and the owner reading their weekly check-in. The fastest way into AI work is a shipped project with a business owner's name on it.

Join any dayHow it works for students
One line on your CV
Before

Interested in AI. Completed an online course.

After

Built and shipped a working AI agent for a US business, reviewed weekly by the owner, then kept on a monthly retainer. Reference letter. Referrals with proof of work attached.

What you walk out with

  1. A shipped project, not a certificate

    A working agent, running inside a real US business, with the code and the one-page handover you wrote. It answers the question every interview asks: what have you built?

    • You build it on the business’s real work, not a practice brief.
    • You write the one-page handover the owner keeps.
    • Your public page can show what you built, after a confidentiality check.

  2. A reference letter from the owner

    Every intern leaves with one, signed by the business owner after the walkthrough. It says what you built and what it does for them.

    • The owner writes it after you walk them through the agent.
    • Download it from your course home whenever you need it.
    • Each extra placement brings its own letter.

  3. Referrals that carry your proof

    The owner can refer you to other businesses in one click. Your brief, your weekly check-in log, your approved capstone and their letter travel with it, on a page anyone can open.

    • The owner refers you to another business in one click.
    • Anyone with the link can open the page, no account needed.
    • You can withdraw a referral if you no longer want it shared.

  4. A real chance of being hired

    Many owners want the person who built their agent to build the next one: as staff, on contract, or on a monthly retainer through us, as their Forward Deployed Engineer. It's a chance, not a promise.

    • Hiring you as staff is between you and the business, with nothing to pay us.
    • Or the business keeps you on a monthly retainer through us.
    • Either way, the agent you built is the reason they ask.

After the internship, the business can keep you on a monthly retainer through us, and you keep 80% of it. How retainers work

A job, a contract or a referral is a chance, not a promise.

Your next week could be a lot quieter.

15-minute interview. Nothing to pay. You approve everything that goes out, and you keep the software.
